What is the equation of the line that passes through the points (-3,4) and (6,7)
inn [45]
Y=mx+b, m=(y2-y1)/(x2-x1)

m=(7-4)/(6--3)=3/9=1/3

y=x/3 +b, now use either point to solve for b, I'll use (6,7)

7=6/3 +b

7=2+b

b=5 so our line is:

y=x/3 +5 or more neatly...

y=(x+15)/3

4. The cosine function can be made to have the same values as the sine function for each angle by including a shifted _______ in
r-ruslan [8.4K]

Answer: Option D

phase

Step-by-step explanation:

By definition, the cosine function has the following form

y = cos (x - \phi)

Where \phi is known as the phase angle

By definition the sinx function is equal to the cosx function with a phase shift of \frac{\pi}{2}

So if we have the function

y = cos (x - \phi) and we want to transform it into the function y=sin(x) then \phi = \frac{\pi}{2}

Finally

y = cos(x - \frac{\pi}{2})=sin(x)

the answer is the option D

Darryl and Kayla sold pies for a school fundraiser. Darryl made $38 from 2 chocolate pies and 4 apple pies. Kayla made $138 from
REY [17]

Answer:

$3

Step-by-step explanation:

Let chocolate pie be x and apple pie be y

Darryl made $38 from 2 chocolate pies and 4 apple pies

That’s

2x + 4y = $38

Kayla made $138 from 14 chocolate pies and 12 apple pies

That’s

14x + 12y = $138

We now have two equations

Equation 1 : 2x + 4y = 38

Equation 2: 14x + 12y = 138

Multiply equation one by 12 and equation 2 by 4 to eliminate apple pie y

We have

12 x 2x + 12 x 4y = 12 x 38

4 x 14x + 4 x 12y = 4 x 138

24x + 48y = 456

56x + 48y = 552

Subtract equation equation two from one

-32x = -96

Divide both sides by -32

x = -96/-32

x = 3

A chocolate pie cost $3
