Show me how to work the equation 30-f+8f=30

ELEN [110]

30-f+8f=30

30+7f=30

Move +30 to the right side. Sign changes from +30 to -30.

30-30+7f=30-30

7f=0

Divde by 7

7f/7=0/7

Cross out 7 and 7, divide by 7. Becomes 1*1*f=f

f=0

Answer: f=0

A line passes through the given points. Write an equation for the line in point-slope form. Then rewrite the equation in slope-i

Andre45 [30]

Answer:

The answer to your question is a) y - 2 = -5(x - 3)

b) y = -5x + 17

Step-by-step explanation:

Data

A (1, 12)

B (3, 2)

Process

1.- Find the slope

Formula

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

Substitution

$m = \frac{2 - 12}{3 - 1} = \frac{-10}{2} = - 5$

2.- Find the equation in point slope form

Equation

y - y1 = m(x - x1)

Substitution and equation

y - 2 = -5(x - 3)

3.- Find the slope-intercept form

Expand the point slope form

y - 2 = -5x + 15

Simplify

y = -5x + 15 + 2

Equation

y = -5x + 17

Solve for x than find the perimeter

My name is Ann [436]

Answer:

136 in

Step-by-step explanation:

Assuming the figure is a square with equal sides, then

4x - 2 = 3x + 7 ( subtract 3x from both sides )

x - 2 = 7 ( add 2 to both sides )

x = 9

Thus side = 3x + 7 = 3(9) + 7 = 27 + 7 = 34

Thus

perimeter = 4 × 34 = 136 in
