Answer:

slope: 3; vertex: (5, -8)

Step-by-step explanation:

Compare the given y+8=3(x−5) to the slope-vertex form y - k = m(x - h). We see that the slope, m, must be 3 and the vertex must be (h, k): (5, -8).

The ordered pairs (1, 1), (2, 8), (3, 27), (4, 64), and (5, 125) represent a function. What is a rule that represents this funct

Zarrin [17]

The functions would be:

D. y=x³

We can check it out.

(1,1); x=1; y=1 ⇒1=(1)³=1*1*1=1
(2,8); x=2; y=8 ⇒8=(2)³=2*2*2=8
(3,27); x=3; y=27 ⇒27=3³=3*3*3=27
(4,64): x=4; y=64 ⇒64=4³=4*4*4=64
(5,125); x=5; y=125 ⇔ 125=5³=5*5*5=125

Jefferson Middle School needs to see a 300% gain in PTO fundraiser

Ronch [10]

Given parameters:

Percentage gain = 300%

Selling cost last year = $2420

Unknown:

Selling cost this year = ?

Solution:

To solve this problem;

Profit percent = $\frac{Selling cost this year - Selling cost last year}{Selling cost last year} x 100$

300 = $\frac{S - 2420}{2420} x 100$

3 = $\frac{S - 2420}{2420}$

S- 2420 = 7260

S = $9680

To make a 300% gain, Jefferson Middle school needs a $9680 from fundraiser sales this year.
