Answer:

-7x - 2

Step-by-step explanation:

First, find the new slope that is perpendicular.

1/7 -> 7 -> -7

So far, we have -7x + b. (we use mx + b)

Since you asked for it to pass point A (-1, 5), substitute in x and y.

y = -7x + b

5 = -7(-1) +b

5 = 7 + b

b = -2

So the equation would be -7x - 2.

Your welcome!

Part B Isabella's mother sells the peas and gets $3 for each square foot. So, multiply your answer from Part A by 3 to calculate

choli [55]

Answer:

See Explanation

Step-by-step explanation:

<em>The question is incomplete as the solution to part A (or part A itself) is not given. To solve this, I will assume a value to the supposes solution to part A.</em>

From the question:

1 square foot is sold at $3.

This implies that:

p square foot will be sold at $3p.

So, total sales can be calculated using:

$Total = 3p$

Now assume that p is 10 square feet (from part A).

The total will be:

$Total = 3*10$

$Total = \$30$

GalinKa [24]

4+7=11 i.e. The whole.
7/11=28

1/11=4
Goats are 4/11 therefore
4 x 4= Ans
All the animals add up to 44 and if you check w/ 7/11 it is correct.

a line with a slope of -1/9 passes through point (9,-1). What is its equation in slope intercept form

Elena L [17]

Answer:

$\huge \orange{y = - \frac{1}{9} x} \\$

Step-by-step explanation:

To find an equation of a line when given the slope and a point we use the formula

$y - y_1 = m(x - x_1)$

From the question we have

$y + 1 = - \frac{1}{9} (x - 9) \\ y + 1 = - \frac{1}{9} x + 1 \\ y = - \frac{1}{9} x + 1 - 1$

We have the final answer as

$y = - \frac{1}{9} x \\$

Hope this helps you
