what is –2.5(7.5 – 3x)?
Answer:
-18.75 + 7.5x
Step-by-step explanation:
-2.5(7.5 - 3x)
you can seperate it into
-2.5 * 7.5 and -2.5 * -3x
-2.5 * 7.5 = - 18.75
-2.5 * -3x = 7.5x
so... -2.5(7.5 - 3x) = -18.75 + 7.5x

HELP ASAP !! THANK YOU <3
Answer:
(-1,8)
(1,4)
(3,0)
(5,-4)
Step-by-step explanation:
First off the y intercept is 6 (0,6)
the change of rate is -2 so as y goes up 1 x goes down 2 so when y =1 x = 6-2
so the coordinates would be (1,4) We do this for the rest of the table and get
(-1,8)
(1,4)
(3,0)
(5,-4)

Answer:
Step-by-step explanatio
for 13: A
for 14: Step 1: Recall the definition of an outlier as any value in a data set that is greater than or less than . Step 2: Calculate the IQR, which is the third quartile minus the first quartile, or . ... \displaystyle Q3+1.5*IQR= 89 + 1.5*10 = 104. In the data set, 105 > 104, so it is an outlier.
for 15: not sure at all sorry
13. B) Non-linear
As per its definition, linear means line. If a function is linear, then one can plot it out, and the resulting graph will be a line. This is not the case for the given function, therefore, it is non-linear.
14. A) Yes
An outlier is a data point that does not fit in with the result. It is not in the general region that the rest of the data points fall in. In the given function, the point (0.5, 3) is not in the general region that the rest of the points are in, therefore, it is an outlier.
15. B) Yes, there seems to be two distinct groups of data.
As one can see there appears two be two groups of data. One of them is towards the upper left corner, whereas the other seems to be towards the lower right corner.

you are given 2 supplementary angles.one has a measure of 4x and the other has a measure of 8x. what is x?
Answer:
x=15
Step-by-step explanation:
Supplementary angles are two angles that equal the sum of 180 degrees.
Take 4x and 8x and make it equal to 180
4x+8x=180
Add like terms:
12x=180
Divide:
x=15
To check:
Plug in 15 to both expressions
4(15)=60
8(15)=120
Add them up and they equal 180 degrees

Answer:
Given : The high school stadium contains a track that surrounds a soccer field. The soccer field is 100 yards long and 70 yards wide.
The school decided to cover the semicircles with grass to create a space for stretching and other activities.
To Find: area of one of the semicircles at either end of the track
How many square yards of grass will the school need to cover the entire circle?
Solution:
Diameter of semicircle = 70 yards
Radius of semicircle = 70/2 = 35 yards
Area of semicircle at one end = (1/2)πr²
= (1/2)(22/7)35²
= 1,925 sq yards
area of one of the semicircles at either end of the track = 1,925 sq yards
square yards of grass will the school need to cover the entire circle
= 2 x 1,925
= 3850 sq yards
distance around one of the semicircles at either end of the soccer field = πr = (22/7) 35 = 110 yards
distance around the inner lane of the track = 100 + 100 + 110 + 110
= 420 yards
