The image shows the linear graph for a family that hired a babysitter for a day. The family gave the babysitter some money up front to buy herself some lunch, and then paid her a constant hourly rate for the hours she worked. Click the thumbnail image to see the full size image.
Which 2 of the following statements are TRUE about the SLOPE of this line? Select the TWO statements that are accurate.
A. The slope is 10
B. The slope is 1/10.
C. The slope tells me that the hourly rate for babysitting is $10.
D. The slope tells me that the hourly rate for babysitting is $20.
Answer:
A and c
Step-by-step explanation: i did some research.
The slope of a function is the rate of change of the function.
The true statements are:
A. The slope is 10 C. The slope tells me that the hourly rate for babysitting is $10.From the graph, we have the following points
[tex]\mathbf{(x_1,y_1) = (0,10)}[/tex]
[tex]\mathbf{(x_2,y_2) = (1,20)}[/tex]
The slope (m) is calculated as follows:
[tex]\mathbf{m = \frac{y_2 - y_1}{x_2 - x_1}}[/tex]
So, we have:
[tex]\mathbf{m = \frac{20-10}{1-0}}[/tex]
[tex]\mathbf{m = \frac{10}{1}}[/tex]
[tex]\mathbf{m = 10}[/tex]
The slope is the rate of change of the y values over the x values.
Hence, the true statements are:
A. The slope is 10 C. The slope tells me that the hourly rate for babysitting is $10.Read more about slopes at:

Find the length of the hypotenuse in the triangle below
Answer:
The hypotenuse is 15. Please give Brainilest
Step-by-step explanation:
Since it is a right triangle, it probably follows the Pythagorean theorem
basically saying two legs squared equal hypotenuse squared
[tex]a^2+b^2=c^2[/tex]
In this case, if you know your Pythagorean theorem triples, then the
answer will be 9,12,15
If you don't let me explain
[tex]9^2 = 81\\12^2 = 144\\15^2=225\\\\a^2+b^2=c^2\\9^2+12^2=15^2\\81+144=225\\[/tex]
This is correct
If you don't know how I got this, learn the first five or six Pythagorean theorem triples, and these will be a piece of cake for you. Remember this only works for right triangle though.

write an expression to show the total volume of the two boxes i-ready
Answer:
The answer is 512 in³.
Step-by-step explanation:
The formula for the volume of the box is V = s³.
Since 8 is the side length, substitute s for 8 in the formula: V = 8³.
8³ is the same as 8×8×8, which is equal to 512.
Therefore, the answer is 512 in³.
Hope this helps!
The expression to show the total volume of the two boxes is 512 in.³
What is volume of cube?The volume of a cube is defined as the total number of cubic units occupied by the cube completely. A cube is a three-dimensional solid figure, having 6 square faces. Volume is nothing but the total space occupied by an object.
a) In the given figure, volume of bigger box is s³ and the volume of smaller box is 100 in.³
Total volume =s³+100
b) The volume of larger box has a side length of 8 inches
Now, s³
Where, s is edge, s=8
Volume =8³
= 512 in.³
Therefore, the expression to show the total volume of the two boxes is 512 in.³

After taxes Brianna makes $9.25 per hour. She works for 6 hours a day and 4 days a per week. She puts 32% of her money in a savings account each week?
Answer:
She puts $71.04 into her savings each week
Amount Earned Each Day:
$9.25 x 6 hours = $55.5 per day
Amount Earned Each Week:
$55.5 per shift x 4 times per week = $222 each week
Amount Put Into Savings Account:
$222 x 0.32 (or 32%) = $71.04 in her savings
Amount Kept After Savings:
$222 - $71.04 = $150.96

-5= -10+y how do i reorder this and why do i reorder it in that way? i think i know how to reorder it i'm just confused on why it has to be ordered that way. plz help, thanks!
Answer:
y = 5
Step-by-step explanation:
Ok so you need to move y to its own spot so either on the right or left of the equation. BUT i recommend leaving it and instead moving -10 to the other side. REMEMBER when you move a number to the other side of the equation you change its value so instead of -10 it will become +10. so you will get 10-5=y so 5=y, if you want the y to be on the other side flip them around -y=-5(since you switched them you need to make them minus, or plus if the number was originally negative) SINCE you have minuses on both sides you can cancel them out and you will be left with y=5.
Why you need to reorder:
you need to reorder to find Y there is no way you can find Y without reordering. When you are reordering remember that Y has to be by itself in one side of the equation.
