xy - -4x²
Step-by-step explanation:
(2x - 3y)(4x -y)
2x( 4x -y) -3x( 4x - y)
8x² - 2xy - 12x² + 3xy
8x²- 12x²- 2xy + 3xy
-4x² + xy
xy - -4x²
Answer:
q = 2
Step-by-step explanation:
0.5-0.125q=(q-1)/4
At first, we have to multiply both the sides by 4.
4 × (0.5 - 0.125q) = q - 1
or, 2 - 0.5q = q - 1
now, we change the side by taking constant into the right side and the number into the left side.
2 + 1 = q + 0.5q
or, 3 = q (1 + 0.5)
or, 3 = 1.5 q
or, 1.5 q = 3
or,
= (3 ÷ 1.5) [Dividing both the sides by 1.5]
or, q = 2
Therefore, q = 2
Answer:
-21
Step-by-step explanation:
f(-3) = -4(-3)² + 15 = -4(9) + 15 = -36 + 15 = -21
EF = 50 in.
In similar figures, corresponding sides are proportional. We use the similarity statement ABCD~EFGH to write a proportion:
![\frac{AB}{EF}=\frac{AD}{EH} \\ \\ \frac{30}{x}=\frac{45}{75}](https://tex.z-dn.net/?f=%5Cfrac%7BAB%7D%7BEF%7D%3D%5Cfrac%7BAD%7D%7BEH%7D%0A%5C%5C%0A%5C%5C%20%5Cfrac%7B30%7D%7Bx%7D%3D%5Cfrac%7B45%7D%7B75%7D)
Cross multiply the proportion:
45*x = 75*30
45x = 2250
Divide both sides by 45:
45x/45 = 2250/45
x = 50
Answer:
y/(x - 10)
Step-by-step explanation:
The quantity is x minus ten, which means that it is (x - 10)
y divided by the quantity = y/(x - 10)
