A car company tested a sports car on a road with different inclines. The test driver tested the car by driving a distance of x miles on a flat road, (x2 + 3) miles downhill, and (x − 7) miles uphill. Which simplified expression is equivalent to the total distance, in miles, for which the car was tested?

3x2 − 4
3x2 + 10
x2 + 2x − 4
x2 + 2x + 10

Answers

Answer 1

Answer:

The third option x2 + 2x- 4

Step-by-step explanation:

Total distance = flat road + downhill + uphill

x + (x^2 + 3) + (x -7) = x + x^2 + 3 + x - 7 = x^2 + 2x - 4

Hope that helps!

What property was applied to solve the equation below?

0.36 x = negative 1.8
0.36 (divided by 0.36) x = negative 1.8 (divided by 0.36)
x = negative 5

Answers

Answer:

Division property

Step-by-step explanation:

The property which states that we can divide both side of the equation by the same non-zero number is called the division property of equality.

The goal of dividing an equation is to isolate the unknown variable on one side.

For example, let the equation be:

2×x=10

Since the unknown variable x is being multiplied by the number 2, to isolate the variable an inverse operation needs to be applied - division:

2×x÷2=10÷2

Careful! Never forget to write the same operation on both sides of the equation! When doing so, the solution of the equation stays the same, i.e. we get an equivalent equation.

A cheesecake recipe says, “Mix 12 oz of cream cheese with 15 oz of sugar.”



How many ounces of cream cheese are there for every ounce of sugar?

Answers

Answer:

4/5 of cream cheese per ounce of sugar

Step-by-step explanation:

If you turn 12 and 15 to a fraction it would be 12/15 so from there we can simplify to 4/5 and can’t simplify it anymore thus giving the answer 4/5 or 4/5 ounce of cream cheese per 1 ounce of sugar. Hope this helps!

Answers

Answer:

Stevie earns $600 on Sunday and $217.50 on Saturday. Together it is 817.50 dollars.

Step-by-step explanation:

Sunday Newspaper:

36+4=40 dollars per Sunday Newspaper

40*15=600 dollars

Saturday Newspaper:

12+2.50=14.50 dollars per Saturday newspaper

14.50*15=217.50 dollars

600+217.5=817.50 dollars for 15 Sunday Newspapers and 15 Saturday Newspapers

Step-by-step explanation:

The last one only needs to be explained

36x+4 and 12x+2.50

If x= 15 you have to multiply it by 36 and 12

(36(15) +4) + (12(15) +2.50)

(540+4) + (180+2.50)

544+182.5

What is 6x + 2y = 10 solve for y And if you would be so kind to add the slope and y-intercept thank youuuuu!!!

Answers

Answer:

y = mx + b

Where m is the slope and b is the y-intercept.

To do this we just solve for y.

Subtract 6x from both sides.

-2y = 10 - 6x

Divide both sides by -2.

y = -5 + 3x

m=3

The line has a slope of 3.

Where is 7,0 located on the graph?

Answers

Hi!

When you want to locate coordinates on the graph, you need to trace left and right and up and down depending on what coordinates you are looking for.

For example: You want 7, 0

The first digit on the left (7) indicates the x-coordinate and to locate the x-coordinate, you move horizontally.

7 is a positive number so we move right starting from the origin (0, 0.)

Place your finger on the bottom left corner of your graph, (0, 0) and move to the right 7 times.

You will land on the coordinate (7, 0) because you move to the right 7 times and since the y-coordinate is 0, you do not move up or down. You stay where you are. (to find the y-coordinate, you have to move up or down but in this case, you don't move at all seeing as it is 0.)

Here's a picture :)
