Answer:

(Hope this helps can I pls have brainlist (crown)☺️)

Step-by-step explanation:

To find the x-intercept, substitute in 0 for y and solve for x To find the y-intercept, substitute in 0 for x and solve for y.

Slope: $m=-\frac{4}{5}$

x-intercept(s): ( 5 , 0 )

y-intercept(s): ( 0 , 4 )

1. Identify the vertex and the y-intercept of the graph of the function y=-2(x+ 2)+2.

KATRIN_1 [288]

Answer:

Please let me know if your quadratic is $y=-2(x+2)^2+2$ .

And if so your vertex is (-2,2) and your y-intercept is (0,-6)

Step-by-step explanation:

It says vertex so I'm thinking you meant $y=-2(x+2)^2+2$ . Please correct me if I'm wrong.

The vertex form of a quadratic is $y=a(x-h)^2+k$ . It is called that because it tells you the vertex (h,k).

So if you compare the two forms you should see -h=2 while k=2.

-h=2 implies h=-2.

So the vertex is (h,k)=(-2,2).

To find the y-intercept, set x=0 and find y.

$y=-2(0+2)^2+2$

$y=-2(2)^2+2$

$y=-2(4)+2$

$y=-8+2$

$y=-6$

So the y-intercept is (0,-6).

S(t)=9t-4, find S(4)

melamori03 [73]

For this problem, you need to substitute 4 in for your variable t. the original equation is S(t) and the one you need is S(4) -- in other words, evaluate this equation when t = 4.

S(4) = 9(4) - 4
S(4) = 36 - 4
S(4) = 32 is your answer.

What are the x-intercept and the y-intercept of the graph of 9x - 7y = -63?

trasher [3.6K]

Answer:

x-int: x = -7 and y-int: y = 9

Step-by-step explanation:

9x - 7y = -63

x-int: 9x - 0 = -63

x = -7

y-int: -7y = -63

y = 9
