Answer: x + 18.99 \leq 24

Step-by-step explanation:

Since, the cost of bus fair = x dollars,

Also, a baseball cap which is $18.99 is needed to buy with the given money,

Hence, total expenditure = x + 18.99

While the given money for spending = 24 dollars,

That is, the expenditure can not be exceeded to $ 24.

Thus, the required inequality,

x + 18.99 \leq 24

Write the formula for the parabola that has x- intercepts (3,0) and (8,0), and y- intercept (0,−2)
alexira [117]

Answer:x^2-5x=-12(y+2)

Step-by-step explanation:

Given

Parabola has x-intercept has (3,0) and (8,0)

and Y-intercept as (0,-2)

Now the general equation of parabola is

y=ax^2+bx+c\quad \ldots(i)

Substitute  (0,-2) in (i) we get

-2=c

Now substitute (3,0) in equation (i)

0=a(3)^2+3b-2\quad \ldots(ii)

Now substitute (8,0) in equation (i)

0=a(8)^2+8b-2\quad \ldots(iii)

Solving (ii) and (iii) we get

a=\frac{-1}{12}\ \text{and}\ b=\frac{5}{12}

therefore

y=\frac{-x^2}{12}+\frac{5x}{12}-2

12y=-x^2+5x-24

A local salesman receives a base salary of $975 monthly. He also receives a commission of 7% on all sales over $1250. How much w
slava [35]

Answer:

  $17,321.43

Step-by-step explanation:

The amount of monthly income from commissions would have to be ...

  $2100 -975 = $1125

This is 7% of sales over $1250, so the sales (s) would need to be ...

  1125 = 0.07(s -1250)

  1125 = .07s -87.50 . . eliminate parentheses

  1212.50 = 0.07s . . . . add 87.50

  17,321.43 = s . . . . . . . divide by 0.07

He would have to sell $17,321.43 in a month if he needed an income of $2100.
