Answer:
I think it 90x-30y hopefully it helps
Answer:
A. 45h = 1,575
Step-by-step explanation:
Area of trapezoid = 1,575 cm² (given)
We are given the length of both bases, a = 63 cm and b = 27 cm
We need to find the formula that will enable us determine its height (h).
Thus:
Area of trapezoid = ½(a + b)h
Plug in the values
½(63 + 27)h = 1,575
½(90)h = 1,575
45h = 1,575
The answer is A. 45h = 1,575
Keep dividing by 3 to get the rest of the answers.
“a” affects we there or not the parabola points up or down. Hope this helps!!
Answer:
y = 4 , x = 0
Step-by-step explanation:
4x + 2y =8----------equ{1}
make 4x subject of the formula
4x = 8- 2y.................equ(2)
now, substitute 4x into equ{1}
4(8-2y) + 2y = 8
32 - 8y + 2y = 8
Collect like terms
-8y + 2y = 8 - 32
-6y = -24
divide both sides by -6
y = 4
Substitute y into equ(2)
4x = 8-2(4)
4x = 8 - 8
4x = 0
divide both sides by 4
x = o
CHECK
4(0) + 2(4) =8
0 + 8 = 8
