Answer:

see explanation

Step-by-step explanation:

Choose any value for x, substitute into the equation and solve for y, that is

x = - 1

2(- 1) + y = 8

- 2 + y = 8 ( add 2 to both sides )

y = 10

---------

x = 0

2(0) + y = 8

0 + y = 8

y = 8

----------------

x = 1

2(1) + y = 8

2 + y = 8 ( subtract 2 from both sides )

y = 6

---------------

x = 3

2(3) + y = 8

6 + y = 8 ( subtract 6 from both sides )

y = 2

----------------

4 possible solutions are (- 1, 10 ), (0, 8 ), (1, 6 ) and (3, 2 )

Answer:

80 * 80% = 64 So it's not A

80 * 55% = 44 so it's not B

80 * 100% = 80 so it's not C

80 * 125% = 100 so D is your answer

Write an equation that is perpendicular to x-3y=2 and contains the point (2,4)

Kisachek [45]

perp to x-3y=2 thru (2,4)

For perpendicular we swap the coefficients on x and y, negating one

3x + y = some constant

We get the constant in the obvious way from the point

3x + y = 3(2) + 4 = 6 + 4 = 10

Answer: 3x + y = 10

100 POINTS!!! PLEASE HELP!!!

BabaBlast [244]

For both functions, we can use the rise over run formula to find the slope. Rise over run uses the following formula:

$\frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

Function 1 has the points (0,4) and (3,0). Plug the x and y values into the formula:

$\frac{0-4}{3-0} = \frac{-4}{3}$

Function 1 has a slope of -4/3.

We can take any two points from Function 2. We'll use (0,5) and (4,8). Plug the values into the formula:

$\frac{8 - 5}{4 - 0} = \frac{3}{4}$

Function 2 has a slope of 3/4.

Because the question asks for the steeper slope, we'll convert the slope of Function 1 into a positive number. The slope will now be 4/3.

Compare the slopes of both functions:

$\frac{4}{3} \ \textgreater \ \frac{3}{4}$

Function 1 has the steeper slope, -4/3.

4k-36 = 9k-44 what is k

Effectus [21]

4k-36 = 9k-44

add 36 to both sides:

4k =9k-8

subtract 9k from each side

-5k=-8

k = -8 / -5 = 8/5
