Answer:

y = 3/2x + 7

Step-by-step explanation:

y - 1 = 3/2 (x + 4)

y = 3/2x + b

1 = 3/2(-4) + b

1 = -6 + b

7 = b

Find the prime factorization of 210 A.) 2 X 3 X 5 X 7 B.) 2 X 3 X 35 C.) 2 X 7 X 15

horrorfan [7]

To prime factorization would be A: 2 X 3 X 5 X 7

Because if your do 2 X 3 it would be 6

Then you do 5 X 7 it would be 35

And 6 X 35 would be 210

AND THAT IS FACTORING THE PROBLEM

What are the coordinates of the x-intercepts of the parabola y = x² - 8x + 15?

tamaranim1 [39]

Answer:

(3, 0) and (5, 0)

Step-by-step explanation:

we have

$y=x^{2}-8x+15$

we know that

The x-intercepts are the values of x when the value of y is equal to zero

For y=0

$x^{2}-8x+15=0$

The formula to solve a quadratic equation of the form

$ax^{2} +bx+c=0$

is equal to

$x=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$x^{2}-8x+15=0$

$a=1\\b=-8\\c=15$

substitute in the formula

$x=\frac{-(-8)\pm\sqrt{-8^{2}-4(1)(15)}} {2(1)}$

$x=\frac{8\pm\sqrt{4}} {2}$

$x=\frac{8\pm2} {2}$

$x=\frac{8+2} {2}=5$

$x=\frac{8-2} {2}=3$

x=3, x=5

therefore

The x-intercepts are (3,0) and (5,0)

Find the mean of the data in the dot plot below

Firdavs [7]

The mean would be 5
Reason for this is that the mean is when all data is summed up then divided by how many data points there are
So 4+4+7=15
Then divide by 3 would equal 5
I hope this helps!
