Simplifying
h(t) = -1t2 + -2t + 30
Multiply h * t
ht = -1t2 + -2t + 30
Reorder the terms:
ht = 30 + -2t + -1t2
Solving
ht = 30 + -2t + -1t2
Solving for variable 'h'.
Move all terms containing h to the left, all other terms to the right.
Divide each side by 't'.
h = 30t-1 + -2 + -1t
Simplifying
h = 30t-1 + -2 + -1t
Reorder the terms:
h = -2 + 30t-1 + -1t
Answer:
a. 12 years
b. 30 years
Step-by-step explanation:
a) Assume Liaqat's age is x. His age would be:
5x + 10 = 70
5x = 70- 10
x = (70 - 10) / 5
x = 12
<em>Liaqat is 12 years old.</em>
b. Assume his uncle's age is y;
4y - 10 = 130
4y = 130 - 10
y = (130 - 10) / 4
y = 30
<em>Liaqat's uncle is 30 years old. </em>
Answer:
8y + 6x
Step-by-step explanation:
Combine like terms
y + 3x +4y + x + 3y + 2x
= (y + 4y + 3y) + ( 3x + x + 2x)
= 8y + 6x
