Answer:
2y² - 5y + 2
Step-by-step explanation:
Original equation:
2y² - 9y - 2 + 4(y + 1) =
Use distributive property
4 · y = 4y
4 · 1 = 4
Plug these values back into the equation:
2y² - 9y - 2 + 4y + 4 = ?
Combine like terms
2y² - 5y - 2 + 4
Combine more like terms
2y² - 5y + 2
That is the most simplified version

Answer:
The equation of the line is y = (5/2)x + 5.
Step-by-step explanation:
When both line are parallel, they share the same gradient value so the equation will be y = (5/2)x + b. Next, you have to find the value of b, by substituting the coordinates into the equation :
y = (5/2)x + b
let x = -2, y = 0,
0 = (5/2)(-2) + b
0 = -5 + b
b = 5
Answer:
y=5/2x+5
Step-by-step explanation:
Since both lines are parallel they have the same slope. From y=5/2x+1, the slope is 5/2
The equation of the line passing through (-2,0) using slope intercept form is
y-y1=m(x-x1)
y-0=5/2(x--2)
y=5/2(x+2)
y=5/2x+5

Step-by-step explanation:
(3²)² is 9², and (10³)² is 1000² so its 9² x 1000² or 9000² or 81 million, 81000000.

worth a brainliest I need help on a and b!! I won't be accepting any ridiculous answers and if you do answer something stupid like "I can't read it. Sorry. Too small." Or "idk haha" I won't hesitate to spam all of your answers with the same response you gave me, taking your points...
Answer:
For answer a,
the equation is -1 - 5
this equals -6
From -1 to -6 is 5
A.) The difference is 5
For answer b,
the equation is -7 - (-3)
There are two minus signs by the -3 so that means to turn those two signs into a plus sign
- 7 + 3
Start at -7 and move to the right 3
You will end up at -4
B.) The difference is 3

The length of a rectangle is 10 more than 10 twice the width , if the perimeter is 80inches find the length the width
Answer:
The width is 10 inches
The length is 30 inches
Step-by-step explanation:
Perimeter of a Rectangle
The perimeter of a rectangle of length L and width W is calculated as follows:
P = 2L + 2W
It's given the length of a rectangle is 10 more than twice the width:
L = 2W + 10
Substituting into the formula of the perimeter:
P = 2(2W + 10) + 2W
Operating:
P = 4W + 20 + 2W
P = 6W + 20
It's given this perimeter is 80 inches, thus
6W + 20 = 80
Subtracting 20:
6W = 80 - 20 = 60
Dividing by 6:
W = 60 /6 = 10
Since :
L = 2W + 10
L = 2*10 + 10
L = 30
The width is 10 inches
The length is 30 inches

Answer:
5 and a half hours
Step-by-step explanation:
How many times does 50 go in to 275
1. 50
2. 100
3. 150
4. 200
5. 250
and to get 275 you add half of 50 which is 25
Answer:
5 hours and 30 minutes.
Step-by-step explanation:
5x50=250
remainder 25
half of an hour is 30 mins and half of 50 is 25.

Answer:
The sequence 18
Step-by-step explanation:
After Nolan brings down a zero, the dividend Nolan will be 20, the same one he started with. So, he will get the same result he has gotten so far: the first quotient digit is 1 and the second quotient digit is 8, resulting in a new dividend of 20 (after the 0 is brought down).
The digits 18 will repeat until Nolan gets tired.

The two triangles below are similar. What value of Q and B would make this true
Answer:
∠B = ∠Q = 26°Step-by-step explanation:
The angles B and Q should be same, therefore:
Q = 4x + 2 and B = 15x - 64The equation below as per above, solving for x:
4x + 2 = 15x - 6415x - 4x = 64 +211x = 66x = 6Then the angle measures:
4*6 + 2 = 26°What is the slope indicated in the table below?*
X. 8 6 4 2
Y. 2 4 6 8
Answer:
-1
Step-by-step explanation:
in order to find the slope you need to look at the change in x over the change in y. x is decreasing by 2 every time, and y is increasing by 2. you now have -2/2 simplify and you get -1
Please help me....Could you answer these 2 questions correctly?
Answer:
A
Step-by-step explanation:
for the two of them, the first answer is the answer
Answer:
#1 - First option: y + 7 = [tex]\frac{-1}{4}[/tex](x -4)
#2 - First option: y = 2x - 5
Step-by-step explanation:
#1
Given: (x1,y1) = (4,-7) and m = [tex]\frac{-1}{4}[/tex];
To find the point slope form which is
y - y1 = m(x - x1); substitute (x1,y1) and m
y - (-7) = [tex]\frac{-1}{4}[/tex](x -4)
y + 7 = [tex]\frac{-1}{4}[/tex](x -4)
#2
Given: points (x1,y1) = (0, -5) and (x2,y2)=(4,3)
To find the slope we use
m = [tex]\frac{(y2-y1)}{(x2-x1)}[/tex] = [tex]\frac{(3-(-5))}{(4-0)}[/tex] = [tex]\frac{8}{4}[/tex] = 2
Now pick a number to find b
y = mx + b
y1 = mx1 + b
-5 = 2(0) + b
b = -5
now plug into y = mx + b; which is
y = 2x - 5

Answer:
Im not sure how you are supposed to answer this but they are similar by side angle side
Step-by-step explanation:
We are given that NO/OQ=PO/OM
This tells us that the sides are in a ratio.
We also know that angle NOM is equal to angle POQ
Now we have 2 sides and 1 angle thus they are similar by side angle side

x=1160
Write an equation for the line parallel to the given line that contains C.
y =
Answer:
y=3/7x+46/7
Step-by-step explanation:
Parallel lines have the same slope. This means in the equation y=mx+b, m=3/7 for sure. Then, it gives us the point (1,7). The line has to go through this point so we plug it in: 7=3/7(1)+C. Then, we solve for C using algebra.
7-3/7=C
C=46/7

Answer:
(4,5)
Step-by-step explanation:
I solved through substitution
3x+2y=22
x-2y=-6 ----> -2y=-6-x ----> -2y=-x-6 -----> y=1/2x+3
Solving for x:
3x+2y=22
3x+2(1/2x+3)=22
3x+x+6=22
4x+6=22
4x=16
x=4
Solving for y:
x-2y=-6
4-2y=-6
-2y=-10
y=5
