Answer:

To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.

What is the slope intercept form of the equation y+18=2(x-1)
statuscvo [17]
<h2>The slope intercept form of the given equation is: y  = 2x +  ( - 20)   </h2>

Step-by-step explanation:

Given,

The equation y + 18 = 2( x - 1)

To write the given equation in the slope intercept form = ?

∴ The equation y + 18 = 2( x - 1)

⇒ y + 18 = 2x - 2

⇒ y  = 2x - 2 - 18

⇒ y  = 2x - 20

⇒ y  = 2x +  ( - 20)                  ..... (1)

We know that,

The equation of slope intercept form,

y = mx + c

Where, m is the sope and c is the y-intercept

∴ The slope intercept form of the given equation is: y  = 2x +  ( - 20)

The are of a shaded region is 118 ft squared. Which equation can be- used to find the value of X, in feet?
Triss [41]

Answer:

x^2+ 18x -130=0

Step-by-step explanation:

Given

See attachment for diagram

Required

The equation to find x

First, calculate the area of the big rectangle using:

Area = Length * Width

So:

A_1 = (x + 6) * (3x - 2)

The smaller rectangle

A_2 = (x - 1) * (2x)

The difference between this areas give the area of the shaded region.

So:

A_1 - A_1 = 118

(x+6)*(3x-2) - (x-1)*2x = 118

Open brackets

3x^2 - 2x + 18x -12 -2x^2 +2x = 118

Collect like terms

3x^2 -2x^2- 2x +2x+ 18x -12   - 118=0

x^2+ 18x -130=0

<em>The above equation can be used to solve for x</em>
