Answer:
16
Step-by-step explanation:
f ( x ) = 3x² - 2x
To find : f ( - 2 )
f ( - 2 ) = f ( x )
Here,
x = - 2
f ( - 2 ) = 3 ( - 2 )² - 2 ( - 2 )
= 3 ( 4 ) - 2*( - 2 )
= 3*4 + 4
= 12 + 4
f ( - 2 ) = 16
Answer:
19b-4
Step-by-step explanation:
7b+3(4b-2)+6÷3
Bracket comes first so we distribute 3 over the terms in the bracket
= 7b + 12b -6 +6 ÷ 3
First we solve division
= 7b + 12b -6 +6 ÷ 3
= 7b + 12b -6 +2
= (7b+12b)+(-6+2)
= 19b -4
This can't be simplified further as it can't be solved anymore
Decreasing by $52 every year, we need to subtract 52 for each year.
350 is the original price.
52x is the amount decreased by how many years
350 - 52(3) = ?
350-156 = 194
Answer: Matt should sell his iPod for $194 in 3 years
Answer: 35 pies
Step-by-step explanation:
Ken can bake 1 pie with each additional cup of sugar he buys. 1 pie =1 cup
4 + x = y
Where;
x= additional pies
y= total pies
If 1 cup= 1 pie; then 31 cups =
31 cup × 1 pie/1 cup = x
:. x= 31 pies
y= x + 4
y= 31+4 = 35
