Answer:

<h2>The warmest temperature was -13F</h2>

Step-by-step explanation:

We are expected to compute the warmest temperature recorded at Minneapolis

Step one:

We are told that on January 30th of 2019 was the coldest day at Minneapolis

hence the temperature reading= -28F------this is like 28 points away from 0 on the number line

Step two:

We are given that the warmest temperature recorded is 15F higher.

since the -ve sign represent cold or snowy weather, the warm temperature

is gotten by adding 15F to the negative temperature

=-28+15

= -13F

<u>The warmest temperature was -13F</u>

Emanuel works as a car salesman. He makes $13 an hour plus a commission of 5% on all cars he sells. Last month he worked 40 hour
gtnhenbr [62]

Solution: Emanuel earns $13 per hour. Also he earns a commission of 5% on all cars he sells.

Number of hours Emanuel worked last month = 40 hours

He sold cars worth $120,000.

Therefore, the total earning of Emanuel is:

13 \times 40 + 5\% of 120,000

520 + \frac{5}{100} \times 120,000

520+6000

6520

Hence, last month Emanuel made $6520, including his hourly pay and commissions.

Consider this system of equations. Which shows the second equation written in slope intercept form?
lora16 [44]

Answer: Second option.

Step-by-step explanation:

The Slope-Intercept form of the equation of the line is:

y=mx+b

Where "m" is the slope of the line and "b" is the y-intercept.

You know that the second equation of the System of equations given in the exercise is:

10(x+\frac{3}{5})=2y

Then, you need to solve for the variable "y" in order to write it in Slope-Intercept form. The steps are:

1. Apply the Distributive property and simplify:

10x+\frac{30}{5}=2y\\\\10x+6=2y

2. Now subtract 6 from both sides of the equation:

10x+6-6=2y-6\\\\10x=2y-6

3. Subtract 2y from both sides of the equation:

10x-2y=2y-6-2y\\\\10x-2y=-6

4. Subtract 10x from both sides:

10x-2y-10x=-6-10x\\\\-2y=-10x-6

5. Divide both sides by -2:

\frac{-2y}{-2}=\frac{-10x-6}{-2}\\\\y=5x+3

Write a polynomial in standard form that meets the following conditions. Assume a=1 and your function is f(x), The zeros are 5 a
jeka57 [31]

Polynomials are equations that uses variables and several terms

The polynomial in standard form is f(x) = x^2 - x -20

<h3>How to determine the polynomial</h3>

The polynomial has 2 zeros.

So, the form of the polynomial is:

f(x) = a(x - x1)(x - x2)

The zeros of the polynomial are 5 and -4.

So, the equation becomes

f(x) = a(x - 5)(x + 4)

The value of a = 1.

So, we have;

f(x) = 1(x - 5)(x + 4)

This gives

f(x) = (x - 5)(x + 4)

Expand

f(x) = x^2 - x -20

Hence, the polynomial in standard form is f(x) = x^2 - x -20
