Answer:
(f+g)(x) = x^2 +10x +7
Step-by-step explanation:
(f+g)(x) = f(x) +g(x) = (15x +7) +(x^2 -5x)
= x^2 +x(15 -5) +7
= x^2 +10x +7

Answer:
The First table is going by 6 on the top, the bottom is going by 1.5.
<u> 6 12 18 24</u>
1.5 3 4.5 6
The Second table is going by multiplying by 2 on the top, the bottom is doing the same thing(from least to greatest).
<u>112.8 56.4 28.2 14.1 </u>
5,640 2,820 1,140 570
The cost per pound of apples on sale is $1.50.
3÷2= 1.50
You can buy 12 pounds of apples for $18.00.
18.00÷1.5= 12
Since 1 pound=16 ounces, so there are about 3 apples in each pound.
16÷5= 3.2
You can buy approximately 36 apples with $18.00.
12×3= 36
Answer:
The value of a = 14
Step-by-step explanation:
Given
(x₁, y₁) = (2, 4)
(x₂, y₂) = (6, a)
(x₃, y₃) = (-1, 1)
A = 9 sq.units
Area of a triangle with vertices (x₁, y₁), (x₂, y₂), and (x₃, y₃) is:

substituting the values (x₁, y₁) = (2, 4), (x₂, y₂) = (6, a), (x₃, y₃) = (-1, 1), A = 9 in th formula


Multiply both sides by 2

simplify

As the area is always positive.
so


Add 18 to both sides

simplify



Divide both sides by 3


Thus, the value of a = 14
