O D. -2

Answer:
A. 3
Step-by-step explanation:
The formula for slope is (y2-y1)/(x2-x1), for two points (x1,y1) and (x2,y2) on the line.
Our points are (-1,-1) and (1,5):
(5-(-1))/(1-(-1))
6/2
3
The slope of the line shown below is 3.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
We have,
Points from the graph (1, 5) and (-1,-1).
So, the slope of line
= (-1 - 5)/ (-1 - 1)
= -6 / (-2)
= 3
Thus, the slope of line is 3.

If a shirt selling for $18 is marked upto $20 then the % increase is
equal to
a. 11%
b. 10%
c. 12%
d. 9%
Answer:
11%
Step-by-step explanation:
it is a simple question, whenever you need to find % increase or % decrease.
always divide the increase as in this case $2 by the original amount which is $18 and multiply it by 100 as you need to take the %.
so,
2/18*100 gives you 11.11% * is multiply
Step-by-step explanation:
$20 - $18 = $2
to get % of increase we need to know what % of $18 the $2 are.
$2 ÷ $18 = 0.11111111........
Multiply this number by 100 and you will get the percentage.
0.111111111111........ x 100 = 11.1111111111....%

area of a circle is 254.34 cm2. What is the diameter of the circle, use 3.14.
The area of a circle is:
Area = PI x r^2 ( r is the radius which is half the diameter)
Using the information in the problem:
254.34 = 3.14 x r^2
Divide both sides by 3.14:
81 = r^2
Take the square root of both sides:
r = 9
The diameter = 2r = 2(9) = 18 cm

Which number is composite?
A. 36
B. 2
C. 19
D. 23
Answer:
A. 36
Step-by-step explanation:
A composite number is a number that can be divided evenly by more numbers than 1 and itself. It is the opposite of a prime number. The number 36 can be evenly divided by 1, 2, 3, 4, 6, 9, 12, 18 and 36, with no remainder. Since 36 cannot be divided by just 1 and 36, it is a composite number.

marissa rode her bike to the park and back home. halfway to the park, she stopped at the library. she lives 1 3/10 miles from the library. how many miles did marissa ride her bike in all?
Answer:
5 2/10 miles or 5 1/5 miles, if you need to reduce fractions
Step-by-step explanation:
The way they wrote this is kind of confusing. Home to library = 1 3/10 miles. That's halfway to the park, so the distance to the park is 1 3/10 + 1 3/10 = 2 6/10 miles.
Then she had to ride that same distance home, so add
2 6/10 + 2 6/10 = 4 12/10 = 5 2/10
If your teacher has you reduce fractions, then it's 5 1/5 miles.
The number of miles did marissa ride her bike in all should be 5 2/10 miles or 5 1/5 miles.
Calculation of the number of miles:Since
She lives 1 3/10 miles from the library.
So here the distance to the park should be
= 1 3/10 + 1 3/10
= 2 6/10 miles.
Now we basically add it
= 2 6/10 + 2 6/10
= 4 12/10
= 5 2/10
hence, The number of miles did marissa ride her bike in all should be 5 2/10 miles or 5 1/5 miles.

Your job in a company is to fill quart size bottles of oil from a full 150- gallon oil tank. Then you are to pack 24 quarts of oil in a case to ship to a store. How many full cases of oil can you get from a full 150- gallon oil tank?
Answer:
25
Step-by-step explanation:
I gallon is 4 quarts so that would be a 600 quarts oil tank so since each case is 24 quarts 600/24 = 25
150 gallons of oil is equivalent to 600 quarts. A full 150-gallon oil tank can yield 25 full cases, with each case containing 24 quarts
The concept used to solve the problem is conversion:
The conversion factor that 1 gallon is equal to 4 quarts.
Given that,
Job: Fill quart-size bottles of oil from a full 150-gallon oil tank.
Packaging: Pack 24 quarts of oil in a case to ship to a store.
Tank Capacity: The oil tank is full and has a capacity of 150 gallons.
Convert the measurements to a common unit.
Since we have to fill quart-size bottles,
Convert 150 gallons to quarts.
Since 1 gallon is = 4 quarts,
So 150 gallons would be 150 x 4 = 600 quarts.
To determine how many full cases of oil we can pack from 600 quarts. Each case contains 24 quarts.
To find the number of cases,
Divide the total number of quarts by the number of quarts per case:
600 quarts ÷ 24 quarts/case
= 25 cases.
Therefore,
You can get 25 full cases of oil from a full 150-gallon oil tank.

The length of each side of an equilateral triangle is increased by 6 inches, so the perimeter is now 60 inches. What was the original length of each side of the equilateral triangle?
Answer:
14 inches
Step-by-step explanation:
Using this information, we can form an equation.
Since there are 3 sides in a triangle, and each side increased by 6, that means that the perimeter increased by 18 inches. Down below, I did 3x because there are 3 sides in a triangle.
(This is the equation you'd want to do to get the answer)
3x + 3 * 6 = 60
Simplify:
3x + 18 = 60
Same to both sides
3x = 42
Isolate x:
x = 14

Answer:
z = [tex]\sqrt{117}[/tex]
Step-by-step explanation:
find 'y' first by using the altitude rule:
y/4 = 9/y
cross-multiply:
y² = 4(9)
y² = 36
y = [tex]\sqrt{36}[/tex] = 6
Find 'z' by using the Pythagorean Theorem with legs equal to 6 and 9
6² + 9² = z²
36 + 81 = z²
117 = z²
z = [tex]\sqrt{117}[/tex]
Factor the expression using the GCF 42-12
