3( x -5)- 5x= 25+ 6x What is the answer and how do you solve this??
stiks02 [169]
1.) expand

3x - 15 - 5x = 25 + 6x

2.) simplify

-2x - 15 = 25 + 6x

3.) add 2x to both sides

-15 = 25 + 6x + 2x

4.) simplify

-15 = 25 + 8x

5.) subtract 25 from both sides

-15 - 25 = 8x

6.) simplify -15 - 25 to -40

-40 = 8x

7.) divide both sides by 8

-40/8 = x

8.) x = -5

Find the Area and Perimeter!
olga_2 [115]

Area of a triangle is 1/2 x base x height.

base = 12

Height = x+6

Area = 1/2 * 12 * x+6

Area = 1/2 * 12x * 72

Area = 6x + 36



Perimeter is the sum of the 3 sides:

x-7 + 12 + 2x+5

3x -2 + 12

3x+10


The last choice is the correct answer.

Find an equation that is perpendicular to the x-axis and passes through the point (7,13)
rjkz [21]

Answer:

x = 7

Step-by-step explanation:

A line perpendicular to the x- axis is a vertical line parallel to the y- axis.

The equation of a vertical line is

x = c

where c is the value of the x- coordinates the line goes through

The line goes through (7, 13) with x- coordinate of 7, thus

x = 7 ← equation of perpendicular line

The functions f and g are defined by f: x = 4 - x and g: x = hx² + k. If the composite function gf is given by gf: x + 2x² - 16x
kozerog [31]

Answer:

Step-by-step explanation:

f(x) = 4-x

g(x) = hx^{2}+k

g(f(x)) = 2x^{2}-16x+26

so put  f(x)  in g(x)

h(4-x)^{2}+k

h((4-x)(4-x) + k

h(x^{2}-8x+16)+k

if h = 2 , then

2x^{2}-16x+32 + k

and we want 26  instead of 32 so subtract 6 so K = (-6)

2x^{2}-16x+32 + (-6)

2x^{2}-16x+32 - 6

2x^{2}-16x+26

h=2

k=(-6)
