Answer:
x= -1
Step-by-step explanation:
5x1 would be -5 then -5 - 2 would be -7
Answer:
x = -1
Step-by-step explanation:
The key thing to remember is that every operation you do on either side needs to be done on the other.
Let's start by getting rid of that -2 you can do that by adding 2 to both sides of the equals sign:
5x - 2 = -7
5x - 2 + 2 = -7 + 2
5x - 0 = -5
5x = -5
The next step is to get rid of that 5 on the left. We can do that by dividing both sides by 5:
5x = -5
5x ÷ 5 = -5 ÷ 5
x = -1
And there you have it! x is equal to negative one.

What is the equation of a line that is parallel to 2x +3y = 3 and passes through the point (3, -4) ?
Answer:
2x + 3y = -6
Step-by-step explanation:
The equation of the new line will be identical to that of the given line except that the constant term will differ.
Start with the given 2x + 3y = 3 and replace x with 3 and y with -4. We get:
2(3) + 3(-4) = C, and C = 6 - 12 = -6
The equation of the new line is therefore 2x + 3y = -6

Write the equation of the line that passes through the points (-8,-1) and (5,-7). Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal line
Answer:
The answer to the question provided is:
[tex]y + 1 = - \frac{6}{13} (x + 8)[/tex]
Step-by-step explanation:
❃Incase you forgot what the point-slope formula is ☟
[tex]y - y_1 = m(x - x_1)[/tex]
❃Incase you also forgot, what the slope formula is ☟
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
➊ First: We are going to be solving for the slope.
[tex]m = \frac{ - 7 - ( - 1)}{5 - ( - 8)} = \frac{ - 6}{ \: 13} = - \frac{6}{13} [/tex]
➋Second: Plug in.
[tex]y + 1 = - \frac{6}{13} (x + 8)[/tex]

Answer:
a. one solution
b. infinetly many solutions
c. one solution
d. no solution
Step-by-step explanation:
brainliest plz :)
The solution of equations are one solution, infinitely many solutions, one solution and no solution.
We are given that;
The four equations
Now,
To determine whether an equation has no solution, one solution, or infinitely many solutions, we can try to solve for the variable and see what happens.
Let's apply this method to each equation:
a. 8p + 1 = 4p + 2
4p + 1 = 2
Subtracting 1 from both sides, we get:
4p = 1
p = 1/4
This is a consistent result, so the equation has one solution: p = 1/4.
b. -6p + 7 = 7 - 6p
Adding 6p to both sides, we get:
7 = 7
This is an identity, so the equation has infinitely many solutions. Any value of p will satisfy the equation.
c. p + 9 = 2p - 3
Subtracting p from both sides, we get:
9 = p - 3
Adding 3 to both sides, we get:
12 = p
This is a consistent result, so the equation has one solution: p = 12.
d. 5p + 3 = 5p - 1
Subtracting 5p from both sides, we get:
3 = -1
This is a contradiction, so the equation has no solution.
Therefore, by the equation answer will be one solution, infinitely many solutions, one solution and no solution.

Max invested $5700 into Brandon's new business where he will earn interest on his investment. After 7 years Max's investment is worth $13300. What is the Total Return on Max's Money? ROUND YOUR ANSWER TO 1 DECIMAL PLACE. The total return is %
Answer: 133.33%
Step-by-step explanation:
Max invested $5,700 into the new business.
After 7 years this came out to be $13,300.
The total return is calculated as:
= [(Ending investment amount - Beginning investment amount) / Beginning investment amount] * 100
= [(13,300 - 5,700) / 5,700] * 100
= 133.33%

Line segment JK is divided by point L in the ratio of 3:2. Endpoint J is at (-16, 2) and point L is at (-15, -20). What are the coordinates of endpoint K?
9514 1404 393
Answer:
K(-14 1/3, -34 2/3)
Step-by-step explanation:
The division ratio says ...
(L -J)/(K -L) = 3/2
2(L -J) = 3(K -L)
5L -2J = 3K
K = (5L -2J)/3
K = (5(-15, -20) -2(-16, 2))/3 = (-75+32, -100-4)/3 = (-43/3, -104/3)
K = (-14 1/3, -34 2/3)

A fit is rolled 25 times and 12 evens are observed. Calculate and interpret a 95% confidence interval to estimate the true proportion of evens rolled on a die.
Answer:
95% confidence interval to estimate the true proportion of evens rolled on a die.
(0.197368 , 0.762632)
Step-by-step explanation:
Explanation:-
Given A fit is rolled 25 times and 12 evens are observed
proportion [tex]p = \frac{x}{n} = \frac{12}{25} = 0.48[/tex]
q = 1 - p = 1- 0.48 = 0.52
Level of significance =0.05

[tex](0.48 - 1.96 \sqrt{\frac{0.48(1-0.48)}{12} } , 0.48 + 1.96 \sqrt{\frac{0.48(1-0.48)}{12} } )[/tex]
( 0.48 - 1.96 (0.1442 , 0.48 + 1.96(0.1442)
( 0.48 - 0.282632 , 0.48 + 0.282632)
(0.197368 , 0.762632)

What is the interquartile range of the data shown in the box plot?
Answer:
12
Step-by-step explanation:
Interquartile range (IQR) = third quartile (Q3) - first quartile (Q1)
From the box plot given, the first quartile is located at the beginning of the edge of the rectangular box = 73,
the third quartile is located at the other edge of the rectangular box to your right = 85
Find x and y so the quadrilateral is a parallelogram.
Answer:
Summary:
The value of x = 7 The value of y = 4Step-by-step explanation:
We know that the diagonals of a parallelogram bisect each other.
As
The parallelogram PQRS is given, so
RT = TP
Given
RT = xTP = 5x-28plug in RT = x and TP = 5x-28 in the equation RT = TP
RT = TP
x = 5x-28
switch the sides
5x-28 = x
adding 28 in both sides
5x-28+28 = x+28
simplify
5x = x+28
subtract x from both sides
5x-x = x+28-x
4x = 28
divide boh sides by 4
4x ÷ 4 = 28 ÷ 4
simplify
x = 7
Therefore, we conclude that the value of x is: x = 7
Similarly,
QT = TS
Given
QT = 5yTS = 2y+12plug in QT = 5y and TS = 2y+12 in the equation QT = TS
QT = TS
5y = 2y+12
subtract 2y from both sides
5y - 2y = 2y+12-2y
simplify
3y = 12
divide both sides by 3
3y ÷ 3 = 12 ÷ 3
simplify
y = 4
Therefore, we conclude that the value of y is: y = 7

The value of x = 7 The value of y = 4HELP ASAP‼️‼️ The price for 4 pounds of ribs is $28

Answer: About 509 seventh-graders attend Parson City Middle School.
Step-by-step explanation:
Total students in the school = 1,340
About 38% of the students are in the seventh grade.
Number of students in the seventh grade = 38% of (Total students in the school)
= 0.38 x (1340) [38%= 0.38]
= 509.2 ≈ 509

Graph y = -3/2x - 3.
Answer:
Step-by-step explanation:
One point can be the y-intercept. We can see that the y-intercept is (0,-3). -3 is the value of y when x = 0. The next point can be when x = 2. If we plug that in the equation, we get the point (2,-6).
Plotting these two points will graph the equation.
The graph is given below.
Some of the coordinates on the graph are (0, -3, (1, -4.5), and (2, -6).
What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
y = (-3/2)x - 3
The coordinates from the given equation are:
When x = 0,
y = - 3
(0, -3)
When x = 1,
y = -3/2 - 3 = (-3 - 6)/2 = -9/2 = -4.5
(1, -4.5)
When x = 2,
y = -3 - 3 = -6
(2, -6)
Now,
The graph of the equation is given below.
Thus,
The graph is given below.
