Answer:
y = 10x^2 + x +21
Step-by-step explanation:
5h-6h=20
-h=20
h=-20
5(-20)-6(-20)=20
-100+120=20
20=20
The answer to solve h would be -20! :)
Answer:
B x = 7
Step-by-step explanation:
You know based on the ratio that it's being scaled by 4 times because the one side 4 is 16 in the bigger pentagon.
So if you go the side that matches the one you need to solve, it's 2.5.
2.5 times 4 = 10 so that bigger pentagon side should equal 10.
The equation x-3 = 10
which means x is 7
Answer:
Q(2, 6 )
Step-by-step explanation:
Using the midpoint formula
let the coordinates of Q = (x, y ), then
0.5(x + 10) = 6 ( multiply both sides by 2 )
x + 10 = 12 ( subtract 10 from both sides )
x = 2
and
0.5(y + 6) = 6 ( multiply both sides by 2 )
y + 6 = 12 ( subtract 6 from both sides )
y = 6
Coordinates of Q = (2, 6 )
