Answer:
The transformation
![(x,y) \rightarrow (x-5,-y+1)](https://tex.z-dn.net/?f=%28x%2Cy%29%20%5Crightarrow%20%28x-5%2C-y%2B1%29)
maps triangle XYZ onto triangle X”Y”Z”.
Step-by-step explanation:
Let us take point Z on the XYZ triangle and see what sequence of transformations we have to apply to map it into the point Z''.
Now Z = (-2, 2) and Z'' = (-7, -1).
The x-coordinate goes from -2 ⇒ -7.
The y-coordinate goes from 2 ⇒ -1.
The x-coordinate is just shifted by -5; thus,
, and the y-coordinate first transforms as
, and is then shifted by 1; thus, it transforms as
.
So we have the full transformation
![(x,y) \rightarrow (x-5,-y+1)](https://tex.z-dn.net/?f=%28x%2Cy%29%20%5Crightarrow%20%28x-5%2C-y%2B1%29)
Hey there,
There are 2 ways
1st way:
Since there are 8 5 point problems, 38 - 8 = 30, will give you the 2 point problems.
2nd way:
8 x 5 = 40
100 - 40 = 60
60 / 2 = 30
Thus there are 30, 2 point problems.
Hope this helps :))

Answer:
1st option
Step-by-step explanation:
Given the 2 equations
2x + 5y = 19 → (1)
y = 3x - 3 → (2)
Substitute y = 3x - 3 into (1)
2x + 5(3x - 3) = 19
Answer:
C
Step-by-step explanation:
It should be 2/3 because there are 6 balls and two of them are green which gives the fraction 2/6 and can be reduced to 1/3
The slope intercept form is y=mx+b
in this case y=-x
y=(-1)x + 0
so the slope m=-1 and y-intercept which is b is 0
