Answer:
The slope is 7
Step-by-step explanation:
Choose any of the following points for example (0.5,3.5) and (1,7)
7-3.5=4.5/1-0.5=0.5
Divide 4.5/0.5 to get 7

Solve the following system of equations algebraically:
y = 4x^2 + 17x + 14
y = 2x + 5
Answer:
When x = -3 y = -1
When x = -3/4 y = 7/2
Step-by-step explanation:
y = 4x^2 + 17x + 14
y = 2x + 5
Set each equation equal to each other
4x^2 + 17x + 14 = 2x + 5
Subtract 2x from each side
4x^2 + 17x-2x + 14 = 2x-2x + 5
4x^2 + 15x + 14 = 5
Subtract 5 from each side
4x^2 + 15x + 14-5 = 5-5
4x^2 + 15x +9 = 0
Factor
(4x+3) ( x+3) =0
Using the zero product property
4x+3 =0 x+3 =0
4x = -3 x=-3
x = -3/4 x=-3
Now we need to find y for each x
x =-3 y = 2x+5 =2(-3)+5 = -6+5 = -1
When x = -3 y = -1
x = -3/4 y = 2(-3/4) +5 = -3/2 +5 = 7/2
When x = -3/4 y = 7/2

Step-by-step explanation:
Timothy went to a baseball game. After the game, he wanted to ride the bus home. The red and blue line buses both stop at the stadium. * A red line and a blue line bus both leave the stadium at 4:00 p.M. * Red line buses leave the stadium every 6 minutes * Blue line buses leave the stadium every 8 minutes If the game is over at 4:30 p.M., what bus will the kids take if they wanted to leave the stadium at the same time after the game was over?
Answer:
Red bus if it takes no time to reach the bus from stadium.
Blue bus if it takes some time to reach the bus from stadium.
Step-by-step explanation:
Given that:
Red bus leaves the stadium every 6 minutes starting from 4:00 PM.
So, the timings for red bus are:
4:00 PM, 4:06 PM, 4:12 PM, 4:18 PM, 4:24 PM, 4:30 PM, 4:36 PM, 4:42 PM, ......
Blue bus leaves the stadium every 8 minutes starting from 4:00 PM.
So, the timings for Blue bus are:
4:00 PM, 4:08 PM, 4:16 PM, 4:24 PM, 4:32 PM, 4:40 PM, 4:48 PM, ......
Also Given that, game is over at 4:30 PM, so near to that time Red bus leaves at 4:30 PM and then Blue bus leaves at 4:32 PM.
Therefore, the answer is:
Red bus if it takes no time to reach the bus from stadium.
Blue bus if it takes some time to reach the bus from stadium.

hey can someone help cus ive been asking this same question for an hour and everyone who responded didnt give a real answer-
=============================================
Work Shown:
Let's call the "height" to be the "width".
The area of a rectangle is
area = length*width
We're told the width is 8.5 feet
If the length is some unknown variable L, then
area = length*width
area = L*8.5
area = 8.5L
We want the area to be at least 76.5 square feet
This means 8.5L is either equal to 76.5, or larger than it
[tex]\text{ area } \ge 76.5\\\\\\8.5L \ge 76.5\\\\\\\frac{8.5L}{8.5} \ge \frac{76.5}{8.5} \ \ \text{ ... divide both sides by 8.5}\\\\\\L \ge 9\\\\\\[/tex]
This shows the length can be 9 feet or larger.
In other words, the minimum length is 9 feet.
Find the equation of the line passing through the point (–1, 0) and parallel to the line y = –1∕2x + 3∕7
Answer:
y = -1/2x - 1/2
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
m - slope
b - y-intercept
Step 1: Define
y = -1/2x + 3/7
Point (-1, 0)
Step 2: Find parallel line
Parallel lines have the same slope as the original but different y-intercepts.
m = -1/2
y = -1/2x + b
0 = -1/2(-1) + b
0 = 1/2 + b
b = -1/2
Step 3: Write parallel line
y = -1/2x - 1/2

an hourly rate of $45. Her total cost for the night was $347.50. How many
hours did Kayla rent the limo? please helppp
Answer:
5.5 hours
Step-by-step explanation:
347.50 - 100 = 247.50
247.50 ÷ 45 = 5.5
Answer:
5.5 hours

Which statement illustrates a simulation that could be used to generate samples of people on a game show selecting either door A, door B, or door C?
A. Flipping a coin and getting heads for door A or tails for door C.
B. Rolling a die; 1 or 2 represents door A, 3 or 4 represents door B, and 5 or 6 represents door C.
C. Creating a spinner divided into 4 equal parts. Label two parts door A, one part door B, and the third part door C.
D. Go to the game show and collect data for a month on which doors people chose.
Answer:
The correct option is;
B. Rolling a die; 1 or 2 represents door A, 3 or 4 represents door B, and 5 or 6 represents door C
Step-by-step explanation:
Given that an onloaded die has equal chances of getting either 1 or 2 or 3 or 4 or 5 or 6, the chances of getting a particular score is therefore 1/6
and the probability of getting a 1 or 2 = 1/6 + 1/6 = 2/6 = 1/3
Therefore, given that the probability, P[tex]_{door}[/tex] of opening door A, or door B, or door C is the probability of selecting 1 out of 3 given as follows;
P[tex]_{door}[/tex](door A) = 1/3
P[tex]_{door}[/tex](door B) = 1/3
P[tex]_{door}[/tex](door C) = 1/3
Therefore, given that the probability of selecting either door A or door B or door C is equivalent to the probability of getting a 1 or 2, or a 3 or 4, or a 5 or 6 on a die.
Answer:
Its B: Rolling a die; 1 or 2 represents door A, 3 or 4 represents door B, and 5 or 6 represents door C.
Step-by-step explanation:
They have to be evenly probable so its B

Write the equation of the line that passes through the given points. (0,-5) and (8,0)
Answer:
[tex]y=\frac{5}{8}x-5[/tex]
Step-by-step explanation:
You're given two points, using that you can use the slope-finding formula:
[tex]slope=\frac{(y^{2} - y^{1}) }{(x^{2} - x^{1})}[/tex]
After that, match up the y-coordinates with each other and the same goes for the x-coordinates. It should look something like this:
[tex]slope = \frac{(0-(-5))}{(8-0)} \\\\=\frac{5}{8}[/tex]
5/8 is your slope. Using the general slope formula y=mx + b, you know that m is the slope and b is the y-intercept. So now you know your slope, plug it into the formula, along with one of the given points. In this case, I will be using (8, 0) because it is easier to solve.
[tex]m = \frac{5}{8}\\ \\y = (\frac{5}{8} )x+b\\(8, 0)\\(0) = \frac{5}{8}(8) + b\\ 0 = 5 + b\\\\-5 =b\\ \\y=\frac{5}{8}x-5[/tex]
You can see I replaced the x and y with the given values accordingly. Then you simplify by subtracting the five on both sides and your y-intercept is -5. Then combine your slope and y-intercept to get your answer!
Hope that helped!

If f(x) = 3x – 7 and g(x) = -x, what is
the value of f(g(2))?
Answer:
C. -19
Step-by-step explanation:
take 2 plug it into g(x)=-x^2 that gives you -4 take that number and plug it into f(x)=3x-7 that gives you -19
Answer:
C) -19
Step-by-step explanation:
Step 1: Define
f(x) = 3x - 7
g(x) = -x²
Step 2: Find g(2)
g(2) = -(2)²
g(2) = -4
Step 3: Find f(g(2)) or f(-4)
f(-2) = 3(-4) - 7
f(-2) = -12 - 7
f(-2) = -19
Part D
Compare your answers in parts B and C. Did your predictions for the coordinates of the reflected images match the actual results? Why or why
Answer/Step-by-step explanation:
Yes, it did because the coordinates of the other polygons would be a direct opposite of polygon ABCD depending on what line it reflects off of. If it reflects off of the y-axis then they would be the same coordinates, just that the X values of the coordinates would now be positive, for the reflection of the x-axis it is also the same except that now the x value would now stay negative while the y values would now be positive. For y=x, it is different because now the X, and Y place values now switch (for example, (-3,-2) would now be (-2,-3)). For y=-x, the place values would both switch, and now be positive.
PS; PLATO does not have an answer this is my personal answer since I am also on this assignment.
Sorry if this response is late! Hope you did well! :)
The coordinates of the reflected images match the actual results because of the following reason.
What is coordinate?Coordinates are two numbers (Cartesian coordinates), or sometimes a letter and a number, that locate a specific point on a grid, known as a coordinate plane. A coordinate plane has four quadrants and two axes: the x axis (horizontal) and y axis (vertical).
Yes, because the coordinates of the other polygons will be in opposite of polygon ABCD depends on what line it reflects off .
Suppose if it reflects off of on the y-axis then the coordinates will be same, only the x- coordinate will be positive.
and if the reflection of the x-axis, the coordinate will be same only the y- coordinate will be negative and the x- coordinate remain positive.
but, For y=x it is different because now the both the x- coordinate and the y- coordinate will be switched with their sign.

-1 + 4 (6x + 3) = 1/2 (-10x - 10) -5
Answer: x = 60/11
Step-by-step explanation:
-1 + 4 (6x + 3) = 1/2 (-10x - 10) -5
Multiply the 1/2 with -10x, and -10.
Let's look on the side that we are working on now.
New equation:
- 1 + 4 (6x + 3) = -5x - 5 - 5
-5-5= -10
-1+4(6x+3)=-10-5x
Next we remove the brackets.
-1 + 4 * 6x + 3 = -10x -5
Now we bring the x's on one side and the non-x's on the other. When we bring a positive x on the other side of an equal sign, it becomes negative. If we bring a negative x on the other side of an equal sign, it becomes positive.
10x * 6x = 1 - 4 - 3 - 5
60x = 1 - 12
60x = -11
x = 60/11
