Answer:
Step-by-step explanation:
y=x²+4x+4
or y=(x+2)²
or y=(x+2)²+0
vertex Is (-2,0)
Answer:
X=4, y=-7
Step-by-step explanation:
To use elimination method, you want to cancel x or y when adding the equations together. So let’s multiply the first equation by -2
2(y)=2(-x-3)
2y=-2x-6
——————
add above equation 2y=-2x-6
to second equation Y=2x-15
add together. 3y=-21
Y=-7
—————————————-
solve for x by substituting y value (7) into either equation
y=-x-3
-7=-x-3
-4=-x
4=x
Scale factor is the ratio of two corresponding sides.
Here we have two triangles, where the preimage is the smaller triangle and the image is the larger triangle.
So scale factor =14/18 = 7/9
And to find the missing variable, we need to set the ratio.
7/9 = 28/x
Cross multiplying both sides
7x = 28*9
x = 36
Answer:
5 is a co efficient and b is a variable together is a term, 3.79 is a constant/term the whole equation is an expression.
Answer:
No, 2 is not 14
Step-by-step explanation:
Evaluate 2*7 you get 2*7 = 14
but 14 is not 2 so no.
