Answer:
[tex]y = \frac{11}{3}x + -\frac{4}{3}[/tex]
Step-by-step explanation:
[tex]y = mx + b\\m = \frac{-5 - 6}{-1 - 2} = \frac{-11}{-3} = \frac{11}{3} \\\\y = \frac{11}{3}x + b\\6 = \frac{11}{3}(2) + b\\6 = \frac{22}{3} + b \\6 - \frac{22}{3} = b \\b = -\frac{4}{3}\\\\y = \frac{11}{3}x + -\frac{4}{3}[/tex]
The probability that Sara wins a raffle is given by the expression n n + 3 . Write down an expression, in the form of a combined single fraction, for the probability that Sara does not win.
Answer:
n/3
Step-by-step explanation:
n×by n is=n square.
n/3
Probability that Sara does not wins a raffle is [tex]\frac{3}{n+3}[/tex].
What is probability?Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are.
Given
Probability that Sara wins a raffle is given by the expression
P(win) = [tex]\frac{n}{n+3}[/tex]
Probability that Sara does not wins a raffle is given by
P(does not win) = 1 - [tex]\frac{n}{n+3}[/tex]
= [tex]\frac{n+3}{n+3} -\frac{n}{n+3}[/tex]
= [tex]\frac{n+3-n}{n+3}[/tex]
= [tex]\frac{3}{n+3}[/tex]
Thus, probability that Sara does not wins a raffle is [tex]\frac{3}{n+3}[/tex].

The function y=f(x) is graphed below. What is the average rate of change of the function f(x) on the interval -8 ≤ x ≤ -1?
Answer:
The average rate of change of the function is: 0
Step-by-step explanation:
The function y = f(x) is graphed below.
From the graph it is clear that:
at x = -8, the value of f(-8) = -10
at x = -1, the value of f(-1) = -10
We have to determine the average rate of change of the function f(x) on the interval -8 ≤ x ≤ -1.
so
at x₁ = -8, f(x₁) = f(-8) = -10
at x₂ = -1, f(x₂) = f(-1) = -10
Using the formula to determine the average rate of change of the function f(x) on the interval -8 ≤ x ≤ -1.
Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]
= [f(-1) - f(-8) ] / [-1-(-8)]
= [-10 - (-10)] / [-1+8]
= [-10 + 10] / 7
= 0 / 7
= 0
Therefore, the average rate of change of the function is: 0
The Henry family drove 276.5 miles on the family vacation. They used 7.9 gallons of gas. How many miles per gallon of gas did they get on the trip?
Answer:To solve this problem you would have to write 276.5 over 7.9 and divide the numerator and denominator by 7.9 since you want miles per gallon (it should have a denominator of 1 after you divide). When you do this you will get 35, so the Henry family got 35 miles per gallon of gas on the trip.

Last week, a pharmacy sold a bottle of shampoo for $5.00. This week, the shampoo sells for $6.50. By what percent did price increase?
Answer:
The percent increase is 30%
Step-by-step explanation:
First find the difference
6.50 - 5.00 = 1.50
Divide by the original cost
1.50 / 5.00
.3
Change to percent
.3 = 30%
The percent increase is 30%
Answer:
30%
Step-by-step explanation:
5.0*30%=1.50
5.0+1.50=6.50

The dance committee of Pine Bluff Middle School earns $ 72 $72dollar sign, 72 from a bake sale and will earn $ 4 $4dollar sign, 4 for each ticket they sell to the Spring Fling dance. The dance will cost $ 400 $400dollar
Answer: See explanation
Step-by-step explanation:
Since the number of tickets is represented by t and we're told that the committee earns $4 per ticket and also earned $72 from bake sale, then the inequality will be given as:
= 72+4t>400
The solution if the inequality will then be:
72 + 4t > 400
4t > 400 - 72
4t > 328
t > 328/4
t > 82

Solve the inequality for x.
- 4x + 16 > -64
A)
X> 12
B)
X > 20
x < 12
D
x < 20
Answer:
D: x < 20
Step-by-step explanation:
-4x + 16 > -64
subtract 16 from both sides because you must isolate x.
-4x + 16 - 16 > -64 - 16
-4x > -80
Then divide -4 on both sides... I believe that when you divide a number by a negative number you must flip the sign...
-4x/ -4 < -80/ -4
x < 20
(negative divided by a negative will result in a POSITIVE.)
Hope this helped... I truly apologize if this is wrong..

What is an equal intercept theorem?The theorem states if a transversal makes equal intercepts on three or more parallel lines, then any other line cutting them will also make equal intercepts. It means that given any three mutually perpendicular lines, a line passing through them forms intercepts in the corresponding ratio of the distances between the lines.
Here, EG = GA - AE
= 36-24
= 12 cm
Here, ΔADE is similar to ΔAGF
Now, AE/GA = AD/FA
⇒ 24/36 = AD/(AD+10)
⇒ 24 (AD+10) = 36AD
⇒ 24AD+240 = 36AD
⇒ 12AD =240
⇒ AD =20 cm
Here, ΔAGF is similar to ΔABC
Now, 30/45 = 36/AC
⇒ 30AC = 36×45
⇒ AC = 54 cm
So, GC = 54-36 = 18 cm
Therefore, the measure of AD is 20 cm, the measure of EG is 12 cm and the measure of GC is 18 cm.

Solve using the order of operations. (9+9+72)-4+9
PLZ ANSWER PLZ HURRY
Answer:
95
Step-by-step explanation:
The order of operations is PEMDAS
Equations in PARENTHESES come first
Numbers with EXPONENTS come second
MULTIPLICATION/DIVISION problems come next (depending on which comes first in the equation
ADDITION/SUBTRACTION comes last (again, depending on which comes first in the equation)
So we do (9+9+72) first
So that equals 90
And then we subtract 4 from 90
90 - 4 = 86
Then we add 9 to 86
86 + 9 = 95

(a) Identify the angle relationship and setup your equation with the given expressions.
(b) What is the value of x? Show your work.
(c) What is the measure of angle A, B, & C? Show your work and make sure to identify which is which.
Answer:
I only know B and C
Step-by-step explanation:
Part B)
2 (x+15) + 3x + 10+ 5x = 180 2x + 30 + 3x + 10 +5x = 180 10 +40 = 180
- 40 -40 10x divided by 10 = 140 divided by 10 x= 14
Part C)
A = 2 (x + 15) = 2 (14 + 15) = 2 * 29 = 58 degrees
< B = 3 x + 10 = 3 * 14 + 10 = 52 degrees
< C = 5 x = 5 * 14 = 70 degrees
