5 0

Easy, find the equation of the line,

Using y=mx+b form:

(-1,3) m=2

3= 2(-1)+b

3= -2+b
+2 +2

5=b

y=2x+5. This is your equation.

Now, plug in the coordinates:

(-3,2)

2= 2(-3)+5
2= -6+5
2= -1

NO

(0,5)

5= 2(0)+5
5=5

YES

(1,5)

5= 2(1)+5
5= 2+5
5=7

NO

(1,4)

4= 2(1)+5
4= 2+5
4=7

NO.

Thus, B, is your answer.

I need help <br> 5=6(1q-5)-19

Rudiy27

ok distribute the 6 by multiplying it by 1q and -5
5=6q-30-19
Now subtract 30-19
5=6q-11
add 11 to both sides
16=6q
divide both sides by 6
q= 16/6
simplify
16/2=8, 6/2=3
q=8/3

Determine the zeros for and the end behavior of f(x) = x(x – 4)(x + 2)^4.

omeli [17]

Answer:

Step-by-step explanation:

x=-2,0,4

it is of 6 th degree (even)

coefficient of leading term is 1 (positive)

so it starts from top on the left and ends also positive direction of y-axis.
