(f + g)(x) = 3x² + 2x - 1
g(x) = 2x - 2

(3x² + 2x - 1) - (2x - 2)
3x² + 2x - 2x - 1 + 2
3x² + 1

f(x) = 3x² + 1

f(x)=(f+g)(x)-g(x)\\
f(x)=3x^2+2x-1 -(2x-2)\\
f(x)=3x^2+2x-1 -2x+2\\
f(x)=3x^2+1\\

Equation for the points (3,8) (2,6) on slope
Irina18 [472]
\frac{8-6}{3-2} = \frac{2}{1}=4

The slope is 2

y=2x + b

Plug in a point to solve for b
8 = 2(3) + b

8 = 6 + b
b = 2

The equation is y = 2x + 2

If the ratio of purple marbles to orange marbles is 3 to 8, how many orange marbles will I have if I have 48 purple marbles?
sveticcg [70]

Answer:

You will have 128 orange marbles

Step-by-step explanation:

Set this up as an equation

Variable x = number of orange marbles

3/8 = 48/x

Cross multiply

3 × x = 8 × 48

3x = 384

Divide both sides by 3 to isolate the variable

3x ÷ 3 = 384 ÷ 3

1x = 128

x = 128

128 orange marbles

Check work:

Substitute the variable x for the answer

3/8 = 48/128

Cross multiply

3 × 128 = 8 × 48

384 = 384

If the numbers equal, the answer is correct
