Answer:

y - y1 = m(x - x1)

y - 6 = 8(x - (-4))

y - 6 = 8(x + 4)

y - 6 = 8x + 32

y = 8x + 32 + 6

y = 8x + 38

Step-by-step explanation:

First you input the given values ( m = 8 and (-4, 6)) into the point-slope equation.

After that, you multiply the 8 by the two terms inside the parentheses, giving you 8x and 32.

Then you add 6 to both sides of the equation to isolate the y.

The slope-intercept equation ends up looking like this: y = 8x + 38

Hope this helps :)

Answer:

y = 8x + 38

Step-by-step explanation:

To find the slope we set up y = mx + b and plug m (our slope) in and then plug in the point into x and y to find b (our y-intercept)

   y = mx + b

   y = 8x + b

   6 = 8(-4) + b

   6 = -32 + b

+32   +32

 38 = b

So using our slope and our intercept we have our slope intercept

y = mx + b

y = 8x + 38

Hope this helps :)

Unit rate<br>How many cents would you earn per minute? <br>Show work<br>ASAP
Yanka [14]
So, it depends. Imma give you two answers, all of which are the same at the end. They just have different ways to do it.

1. So, it's<span> $9 per hour, or $9 per 60 min </span>
<span>You can write a ratio: 9/60 = n/1 </span>
<span>In this case you have to divide 9 by 60 cause
60/60 = 1 </span>
<span>And n=0.15 </span>
<span>Answer: you earn 15 cents per min. 

2.</span><span>$9 = 900 cents </span>
<span>900 cents divided by 60 minutes = 15 cents in a minute.

Hope this helps love!! :)</span>

The graph of the function f(x) = ax^2 + bx + c has vertex at (0, 2) and passes through the point
Ann [662]

Answer:

Step-by-step explanation:

You need to use vertex form of a quadratic to solve this.

Consider the vertex to be (h,k)

Another way of representing a quadratic is in "vertex form":

f(x) = a(x-h)^2+k

Now all you have to do is solve for a.  You know that the vertex is (0,2) and you have know the point of (1,8).  Now, all you have to do is plug in these values and solve for a.

8 = a(1-0)^2+2\\8=a(1)^2+2\\8=a+2\\a=6

Now you know the equation is f(x) = 6(x-0)^2+2 , but you need it in quadratic form.  All you have to do is solve is distribute the 6:

6x^2+2

You get:

a = 6

b = 0

c = 2

Please mark this as brainliest if it satisfies your question

Felix scored 52 and 64 on his first two test in Sociology 212. What must he get on the third test to get an average of the three
Pie

Answer:

Felix's third test score must be greater than 94

Step-by-step explanation:

Felix scores on Sociology 212 tests:

1st test - 52

2nd test - 64

3rd test - x

Find the average of Felix's scores:

\text{Average}=\dfrac{\text{The sum of all scores}}{\text{The total number of scores}}\\ \\\text{Average}=\dfrac{52+64+x}{3}

An average of the three test must be above 70, this means

\text{Average}>70\\ \\\dfrac{52+64+x}{3}>70

Solve this inequality. First, multiply it by 3:

52+64+x>210\\ \\x>210-52-64\\ \\x>94

Answer:

392.5‬     terms of pi = 125π

Step-by-step explanation:

V = πr²h

V = 3.14 x 5² x 5

V = 3.14 x 25 x 5

V = 3.14 x 125

V = 392.5‬

If its terms of pi it should be 125π
