Answer:
x = 1 and y = 2
Step-by-step explanation:
because 100(1) + 50(2) = 100 + 100 = 200
Answer: 7/12
Step-by-step explanation:
1/3 + 1/3 = 2/3
2/3 - 1/3 = 1/3 (Rearrange the denominator together)
= 1/3 + 1/4
(Multiple 1/3 by 4 for the numerator and the denominator)
(Multiply 1/4 by 3 for the numerator and the denominator as well)
= 4 + 3 / 12
=7/12
Answer:
36
Step-by-step explanation:
2(4.5*3)=13.5
2(3+7.5)=22.5
13.5+22.5=36
Answer:
y = 4(x - 2)² + 48
Step-by-step explanation:
Given
y = 4x² - 16x + 64
Using the method of competing the square
Factor out 4 from 4x² - 16x
y = 4(x² - 4x) + 64
add/ subtract ( half the coefficient of the x- term)² to x² - 4x
y = 4(x² + 2(- 2)x + 4 - 4 ) + 64
= 4(x - 2)² - 16 + 64
= 4(x - 2)² + 48
