Answer:

$y+1=-2(x-5)$

Step-by-step explanation:

We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have a point given and a slope from the equation. We will chose point-slope since we have a point and the slope.

We will substitute $m=-2$ and $x_1=5\\y_1=-1$ .

$y-(-1)=-2 (x-5)$

$y+1=-2(x-5)$

This is the equation of the line with slope -2 that passes through (5,-1).

The polynomial p(x)=(3-2x)(x^2-5) is graphed in a coordinate plane. Which statement about the graph is correct?

satela [25.4K]

Answer:

0 = (3-2x) x (x x 2 -5)

(3-2x) x ( x x 2 - 5) = 0

(3-2x) x (2x - 5) = 0

3 - 2x = 0

2x - 5 = 0

x = 3/2

x = 5/2

x1 = 3/2 or x2 = 5/2

To do this you have to times the number of fabric by the length of each fabric
so you have 6*5/8=30/8=15/4 or 3.75

ASHA 777 [7]

Answer: $5,744.61

Step-by-step explanation:

year 1 = -2,277

year 2 = -2026.53

year 3 = -1803.61

year 4 = -1605.21

year 5 = -1428.64

year 6 = -1271.49

year 7 = -1131.62

year 8 = -1007.17

year 9 = -896.36

year 10 = -797.76

year 11 = -710

you are subtracting 11% from each year.

Alicia earned d dollars baby-sitting. Her friend earned twice as much. You earned $2 less than Alicia's friend earned. Write an

Semenov [28]

Answer:

$Total = \$5d - 2$

Step-by-step explanation:

Represent Alice with A, her friend with F and you with Y.

From the question, we have:

$A = \$d$

$F = 2 * A$ --- Twice as much Alice means 2 times Alice's earnings

$Y = F - 2$ --- 2 less than her friend

Required

Determine the total amount

$A = \$d$

Substitute $\$d$ for A in $F = 2 * A$

$F = 2 * \$d$

$F = \$2d$

Substitute $\$2d$ for F in $Y = F - 2$

$Y = \$2d - 2$

The total amount is calculated by adding the earnings of Alice, her friend and you

$Total = A + F + Y$

$Total = \$d + \$2d + \$2d - 2$

$Total = \$5d - 2$

<em>Hence, the total earnings is 5d - 2</em>
