Find the sum or difference 1/4(q-12)+1/3(q+9)

1 answer:

3 0

1/4(q-12) + 1/3(q+9), Then you must use the distributive property to get 1/q-3+1/3q+3. Then you simplify by combining like terms to get, 7/12q. You do not have any constants because they cross each other out.

andriy [413]

Answer:

Part 1) The rate of change is $\frac{1}{3}$

Part 2) The initial value is $12$

Step-by-step explanation:

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope or rate of change

b is the y-intercept or initial value

step 1

Find the slope or rate of change

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have the points

(3,13) and (6,14)

substitute the values in the formula

$m=\frac{14-13}{6-3}$

$m=\frac{1}{3}$

therefore

The rate of change is $\frac{1}{3}$

step 2

Find the initial value

we have

$m=\frac{1}{3}$

$point\ (3,13)$

substitute in the equation $y=mx+b$

$13=\frac{1}{3}(3)+b$

solve for b

$13=1+b$

$b=13-1=12$ ---> initial value

The linear equation is equal to

$y=\frac{1}{3}x+12$

The y-intercept or initial value is 12

What is 4-1/4 help please

miskamm [114]

Answer:

It lets me add one now! The answer is 3.75

Step-by-step explanation:

1/4 of a unit is 25%

When converted to a decimal, 25% = .25

4 - .25 = 3.75

We can check this by using reversive property:

4 - .25 = 3.75

3.75 + .25 = 4
