Answer:

\large\boxed{x=-4}

Step-by-step explanation:

-4x+3=19\qquad\text{subtract 3 from both sides}\\\\-4x+3-3=19-3\\\\-4x=16\qquad\text{divide both sides by (-4)}\\\\\dfrac{-4x}{-4}=\dfrac{16}{-4}\\\\x=-4

Step 1: Combine like terms ( 3 and 19) by subtracting 3 to both sides

-4x + (3-3) = 19 -3

-4x = 16

Step 2: Isolate x by dividing -4 to both sides

\frac{-4x}{-4} =\frac{16}{-4}

x = -4

Hope this helped!

you were 20 inches tall at birth, and 48 inches tall on your 8th birthday. Create a linear equation to represent this equation.
Marianna [84]

Answer:

Part a) y=3.5x+20

Part b) 90\ in

Step-by-step explanation:

Part a) Create a linear equation to represent this situation

Let

x -----> the number of years

y ----> the height in inches

we have the points

(020) ----> at birth the height was 20 inches

(8,48) ---> 8th birthday the height was 48 inches

step 1

Find the linear equation in slope intercept form

y=mx+b

where

m is the slope

b is the y-coordinate of the y-intercept

<em>Find the slope m</em>

m=(48-20)/(8-0)\\m=3.5\ in/year

<em>Find the value of b</em>

b=20\ in ----> the point (0,20) is the y-intercept

substitute

y=3.5x+20

Part b) According to your equation, how tall will you be at age 20?

For x=20 years

substitute the value of x in the linear equation and solve for y

y=3.5(20)+20

y=90\ in
