→Answer:

(1,0)

→Step-by-step explanation:

Well first we need to graph the following equation.

y=-5x^2+8x-3, look at the image below.

So if one x intercept is at (.6,0) then looking at the graph we can see the other one is at (1,0).

Finn and Ellie sell oranges at a produce stand. Finn earns $5 for each crate of oranges he sells. At the end of the week, Ellie
KatRina [158]

The second term in the expression represents a. Finn's earnings at the end of the week.

To answer the question, we need to know what mathematical expressions are.

<h3>What are mathematical expression?</h3>

Mathematical expressions are expressions that show the relationship between two variables.

<h3>Finn's earnings</h3>

Now, let z be the number of crates Finn sold.

Since Finn earns $5 per crate, the total amount he earns at the end of the week is t = amount per crate × number of crates

= 5 × z

= 5z

<h3>Ellie's earnings</h3>

Now since Ellie earns $20 more than Finn, the amount Ellie earns is

T = 20 + t

= 20 + 5z.

So, 5z the second term in the expression represents Finn's earnings at the end of the week.

So, the second term in the expression represents a. Finn's earnings at the end of the week.

Complete the equation of the line whose y intercept is (0,6) and slope is 3
m_a_m_a [10]
Y = mx + b
m = slope
b= y intercept

so the equation is y= 3x + 6

A radio station plays a total of 272 pop, rock, and hip-hop songs during a day. The number of pop songs is 3 times the number of
Norma-Jean [14]
Let the daily played number of pop songs be P, the number of rock songs be R and the number of hip-hop songs be H.

i) 
"A radio station plays a total of 272 pop, rock, and hip-hop songs during a day"

means that : P+R+H=272

ii) 
"The number of pop songs is 3 times the number of rock songs. "

so, P=3R

iii)
"The number of hip-hop songs is 32 more than the number of rock songs."

means: H=32+R

iv)

since both P and H can be written in terms of R, we have:

P+R+H=272

(3R)+R+(32+R)=272

3R+R+32+R=272

5R+32=272

5R=272-32=240

R=240/5=48


vi) 

thus: P=3R=3*48=144,    H=32+R= 32+48=80

Answer: 

48 Rock, 144 Pop and 80 Hip-hop
