What is the slope of the line which contains the ordered pairs (2, 1) and (-3, 5)?
a. -5/4
b. -4
c. -1/4
d. -4/5
Answer:
d. -4/5
Step-by-step explanation:
When using the equation m = y2 - y1 / x2 - x1, we get m = 5-1 / -3-2.
Simplified: m = 4/-5.
The negative can be placed on the numerator or denominator, it doesn't make a difference.

Twice a number, increased by the
sum of the same number and five.
I
Answer:
2x + (x + 2)
Step-by-step explanation:
Let the number = x
"twice a number" means 2x
"increased by the sum of the same number and five" means to add x + 5, so the expression is
2x + (x + 2)

Finding the slope of the line
Answer:
-2
Step-by-step explanation:
Slope of a line is the gradient of a line so I consider points (4,-8) and (0,0) so now u gotta find the gradient that is..
y difference over x difference so,
-8-0 /4-0 so its
-8/4 = -2

What is the slope of a line perpendicular to the line whose equation is 12x-9y=135
Answer:
[tex]\frac{-9}{12}[/tex]
Step-by-step explanation:
First, we need to isolate y.
1. Subtract 12x from both sides.
-9y=-12x+135
2. Divide by -9 in order to isolate y.
[tex]y=\frac{12}{9} x-15[/tex]
3. Understand that perpendicular equations' slopes are opposite and reciprocal to the original equation. The slope of the original equation is [tex]\frac{12}{9}[/tex], so the reciprocal and opposite (flip and change the sign) slope would be [tex]\frac{-9}{12}[/tex].
Josh went to a local barber to get his haircut. It cost $18 for the haircut. Josh tipped the barber 15%. What was the total cost of the haircut including tip?
$20.70
Step-by-step explanation:
15% of 18 is 2.7 so 18 + 2.7 = 20.70
Calculators cost $12.99 each, rulers cost $0.49 each, pencils cost $0.10 each, and erasers
cost $0.05 each. How much would Mrs. Algebra's single order be? Use the expression below
to calculate the total.
Given :
Calculators cost $12.99 each, rulers cost $0.49 each, pencils cost $0.10 each, and erasers cost $0.05 each.
To Find :
How much would Mrs. Algebra's single order be.
Solution :
Total price paid by Mrs. Algebra = Price of pencil + price of ruler + price of calculator + price of eraser.
T = $(0.10 + 0.49 + 12.99 + 0.05)
T = $13.63
Therefore, Mrs. Algebra's single order cost is $13.63 .
Hence, this is the required solution.
7. On Monday, Jeremiah had a debt of $92.80 after buying a pair of Jordan's. Jeremiah was
paid $126.42 from his job at Home Depot on Tuesday. After depositing his check from
Home Depot, what is the amount, in dollars, in Jeremiah's bank account?
A $33.62
B. $219.22
C. $174.42
D. $42.22
Answer:
A $33.62
Step-by-step explanation:
To figure this out you have to take -92.80 and add 126.42 to get $33.62. Have a great day and LEAVE ME ALONE PLZ! <3
Answer:
-92.80+126.42=33.62
Step-by-step explanation
Since you owe $92.80 it would be a negative. So it would be like this.
126.42-92.80= 33.62
Or
-92.80+126.42=33.62

Use the elimination method to solve the system of equations. Choose the correct ordered pair.
-x + y = -2
2x - 3y = 4
A. (3, 1)
B. (4, 2)
C. (2, 0)
D. (5, 3)
Answer:
C. (2, 0)
Step-by-step explanation:
-x + y = -2
2x - 3y = 4
Multiply both sides of the first equation by 2.
Write the second equation below it and add them.
-2x + 2y = -4
(+) 2x - 3y = 4
----------------------------
-y = 0
y = 0
Start again with the original equations.
Multiply both sides of the first equation by 3. Write the second original equation below it and add them.
-3x + 3y = -6
(+) 2x - 3y = 4
-------------------------
-x = -2
x = 2
Answer: C. (2, 0)

Explain why triangle ABC is congruent to triangle FED.
Answer:
The two angles of ΔABC are equal to the two respective angles of ΔFED. Also, the sum of all interior angles of a triangle is 180º. Therefore, third angle of both triangles will also be equal in measure.

A spinner has 8 equal sectors with different letters for each sector, as shown below:
A spinner with 8 equal sectors is shown. The sectors are labeled B, Y, G, P, O, V, M, and R.
Hamlet spins the spinner 13 times, and it stops at the letter R 9 times. If he spins the spinner a 14th time, what is the theoretical probability that this time it will stop at the letter R?
Answer:
The theoretical probability of obtaining letter 'r' at the 14th spin is:
1/8
Step-by-step explanation:
It is given that:
A spinner has 8 equal sectors with different letters for each sector.
The sectors are labeled b, y, g, p, o, v, m, and r.
Hamlet spins the spinner 13 times, and it stops at the letter r 9 times.
We are asked to find the theoretical probability that we will get letter r at the 14th spin.
The theoretical Probability is given as the ratio of number of favorable outcomes to the total number of outcomes.
Hence, the theoretical probability of obtaining letter 'r' at the 14th spin is:
( As there are a total of 8 outcomes( or 8 sectors) out of which there is only one sector which is red)
