General Formulas and Concepts:

<u>Algebra I</u>

  • Composite Functions
  • Combining Like Terms

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 4x² + 1

g(x) = x² - 5

(f + g)(x) is f(x) + g(x)

<u>Step 2: Find (f + g)(x)</u>

  1. Substitute:                    (f + g)(x) = 4x² + 1 + x² - 5
  2. Combine like terms:    (f + g)(x) = 5x² - 4

Really need helpllllll!!!!!

Answer:

The relationship of the number of months and the total amount paid is proportional for both Hanks and Lynn.

Step-by-step explanation:

Let us divide the equation into 2 parts.

Hanks

Hank paid $2000 up front when he bought the car and he pays $200 every month. Therefore, the total amount paid (y)  and the number of month (x)can be expressed as follows.

Let

x = number of month

y = total amount paid

y = 2000 + 200x

The relationship between amount paid and the number of months is proportional

Lynn

She did not paid anything upfront but she paid $275 every month. Therefore,

x = number of month

y = total amount paid

y = 275x

This relationship between amount paid and number of month is directly proportional

I don't know how to solve this and the answer isn't 4 or 0 so what is it?4=-4+a​
nevsk [136]
The answer is 8. This is because when you substitute 8 with “a” you then solve the problem to see if it is equal to the answer. -4+8=4... -4+4=0 so that is wrong and -4+O=-4 which is also incorrect.

Spencer made a quilt for his cousin's doll. The quilt had a 7x7 array of different color square patches. If each patch is 1 3/4
Damm [24]

Answer:

\frac{2401}{16} square inches

Step-by-step explanation:

Given:

The quilt made by Spencer had a 7×7 array of different color square patches such that each patch is 1\frac{3}{4} in long.

To find: the area of the whole quilt

Solution:

Side of each quilt = 7(\frac{3}{4})=7(\frac{7}{4})=\frac{49}{4}

Quilt is in the form of a square such that area of square is given by (side)^2

Therefore, area of quilt = (side)^2=(\frac{49}{4})^2 =\frac{2401}{16}  square inches
