Answer:  C: cubic expression

Step-by-step explanation:

Classify the expression: 5x³ + 2x − 3

we know that

Polynomials can be classified two different ways - by the number of terms and by their degree.

so

a) By the number of terms is a trinomial, because has three terms

b) By their degree The degree of the polynomial is found by looking at the term with the highest exponent on its variable

The highest exponent is 3 so this is a 3rd degree trinomial  

therefore

Is a cubic expression

a customer left a tip of 25$ this is 20% of his bill. whats the price of the bill?

Answers

Answer:

i think 150

Step-by-step explanation:

Answer:  $30.00

Step-by-step explanation:

First, convert the 20% to an actual number that can be used in a calculation. For percents, this is always done by simply dividing the percent (in this case 20%) by 100%.So, the conversational term "20%" becomes 20% / 100% = 0.20 in terms of a real mathematical number.

0.20 x $25.00=$5.00.

$25.00 + $5.00 = $30.00.

1. g(x) = f(x) - 7
how do u solve these?

Answers

Answer:

g' (×)=f

Step-by-step explanation:

g (×)=f×-7

g' (×)= d÷d× (f×-7)

d÷d×(f+g)=d÷d×(f)+d÷d=(g)

g' (×)=d÷d×(f×)-d÷d×(7)

g'(×)=f-d÷d×(7)

g'(×)=f-0

F. -5

Answers

Answer:

-3 and 1

Step-by-step explanation:

The zeros of the given function are -3 and 1.

What are zeros of a function?

The zeros of a function, also referred to as roots or x-intercepts, are the x-values at which the value of the function is 0 (f (x) = 0). The zeros of a function can be thought of as the input values that result in an output of 0.

Given is a function f(x) = (x + 3)(x - 1)/(x-2)(x + 2),

We need to find the zeros of the function,

Equate to 0,

(x + 3)(x - 1)/(x-2)(x + 2) = 0

Therefore,

(x + 3)(x - 1) = 0

x+3 = 0 and x-1 = 0

Therefore,

x = -3, x = 1

Hence, the zeros of the given function are -3 and 1.

There are 40 working hours in a week and 52 weeks a year. How much does Nate need to make an hour to stay out of debt if it costs him $900 to live each month?

Answers

Answer: $5.19

Step-by-step explanation:

If there are 40 working hours in a week and 52 weeks in a year, 40 * 52 should be the amount of working hours in a year.

40 * 52 = 2080 working hours

Nate needs $900 to live each month and there are 12 months in a year, so $900 * 12 would equal how much he spends per year.

$900 * 12 = $10800

Divide $10800 by 2080 working hours to get how much he needs to make per working hour.

10800/2080 = approximately 5.19, rounded down from the nearest hundredth

He needs to make $5.19 per hour, so the answer is the last option.

The correct answer is 5.19

Solve the following system of equations.
2x + 5y = -18 and y = -4x

Answers

Answer:

x=1 and y= -4

Step-by-step explanation:

step one: plug -4x into y in thi]e first equation.

2x+5(-4)= -18

step two: solve for x

2x-20= -18

(add 20 to both sides to eliminate -20 on the right)

2x=2

(divide both sides by 2 to get x by its self)

x=1

step 3: now that we found the value for x plug it in to either equation and solve for y

y= -4x

y= -4(1)

y= -4

Step-by-step explanation:

Given

[tex]\frac{2y-1}{15}[/tex] = [tex]\frac{y}{10}[/tex] ( cross- multiply )

10(2y - 1) = 15y ← distribute left side

20y - 10 = 15y ( subtract 15y from both sides )

5y - 10 = 0 ( add 10 to both sides )

5y = 10 ( divide both sides by 5 )

y = 2
