Answer:

y = - 3x - 19

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 3x + y = 6 into this form

Subtract 3x from both sides

y = - 3x + 6 ← in slope- intercept form

with slope m = - 3

• Parallel lines have equal slopes, hence

y = - 3x + c ← is the partial equation

To find c substitute (- 6, - 1) into the partial equation

- 1 = 18 + c ⇒ c = - 1 - 18 = - 19

y = - 3x - 19 ← is the equation of the parallel line

your formula will ALWAYS be Y=MX+B

3x + Y = 6

subtract 3x from each side

Y = -3x + 6

you’ll use rise over run, 1/3 will be your ratio.

Gre4nikov [31]

Answer: $28-$33

Step-by-step explanation: Call the cost per pair x. She buys the first pair full price, so x, then 2 dollars off, so x-2, and 2 dollars off, so x-2, adding them up you get 3x-4= total money spent. Sinze this ranges from 80-95 solve equations and you get 28 and 33 respectively.

Grace [21]

Answer:

There is a 1-a chance, where a is the complement of the confidence level, that the true value of p will fall in the confidence interval produced from our sample. ( B )

Step-by-step explanation:

Confidence level depicts the probability that the confidence interval actually contains the values of p ( true values of P ) hence

There is a 1-a chance, where a is the complement of the confidence level, that the true value of p will fall in the confidence interval produced from our sample Is a complete misinterpretation of the confidence interval therefore it is NOT true

find the equation of a line that passes through (-3,1) and (-1,-2) and write it in standard form. please help me !

Savatey [412]

Find the slope first
slope=(2-1)/(-1+3)=1/4=.25

now use the slope and either point to write in point slope form
y-1=.25(x-2)
y-1=¼x-½

to rationalize all the denominators multiply by the last common multiple, here we get 4
4y-4=x-2

then put in the correct order

x-4y=-2
