Answer:
m<EFG = [tex]69^{o}[/tex], and m<GFH = [tex]111^{o}[/tex]
Step-by-step explanation:
Linear pair angles are two supplementary angles.
Thus,
m<EFG + m<GFH = [tex]180^{o}[/tex]
2n + 21 + 4n + 15 = [tex]180^{o}[/tex]
collecting like terms, we have:
6n + 36 = [tex]180^{o}[/tex]
6n = [tex]180^{o}[/tex] - 36
6n = [tex]144^{o}[/tex]
divide both both sides by 6,
n = [tex]24^{o}[/tex]
Therefore,
m<EFG = 2n + 21
= 2 x [tex]24^{o}[/tex] + 21
= 48 + 21
= [tex]69^{o}[/tex]
m<GFH = 4n + 15
= 4 x [tex]24^{o}[/tex] + 15
= 96 + 15
= [tex]111^{o}[/tex]
Thus m<EFG = [tex]69^{o}[/tex], and m<GFH = [tex]111^{o}[/tex]

What are the x- and y-intercepts of f(x) = x2 - 49?
Answer:
x-intercepts: (-7, 0) and (7, 0) y-intercept: (0, -49)Step-by-step explanation:
x-intercepts: f(x) = 0
x² - 49 = 0
x² = 49
x = -7 ∨ x = 7
Points: (-7, 0) and (7, 0)
y-intecept: y = f(0)
f(0) = 0² - 49 = -49
Point: (0, -49)
Find the Value of X.

x + 16 + 11x = 172 , that is
12x + 16 = 172 ( subtract 16 from both sides )
12x = 156 ( divide both sides by 12 )
x = 13 → C

7+5+3+y=x+3+12
true or false
Answer:
Hello! :) I hope I’m correct!!
Step-by-step explanation:
The answer would be TRUE.
Step #1. Okay so first, evaluate the left side of the equal sign.
(7 + 5 + 3 + y = 15)
Step #2. Now, you have to evaluate the right side of the equal sign.
( x + 3 + 12 = 15)
Explaintion of the steps: if 15 = 15 than, 7 + 5 + 3 + y = x + 3 + 12 would be true.
Therefore, the answer to your question is TRUE.
Hope these steps where clear & helpful!! :)

Solve the Inequality: -2|1-3h|+9<-12
Answer:
h < -19/6
Step-by-step explanation:
Step 1 : Add -9 to both sides.
-2(|1-3h|)+9<-12
-2(|-3h+1|)+9<-12
Step 1: -2(|-3h+1|)+9+ -9<-12+ -9
-2(|-3h+1|)<-21
step 2: Divide both sides by 2.
-2(|3h+1|) -21
-2 -2
|-3h+1|> 21/2
step 3: solve absolute value.
|-3h+1|> 21/2
or either -3h+1-1> 21/2-1 (subtract 1 from both sides)
-3h>19/2
-3h > 19/2 (divide both sides by -3)
-3 -3
h<-19/6
hope this made sense

Over the course of a month, Katniss caught three times as many squirrels as deer. She also caught five less rabbits than squirrels. The total number of animals she caught is ten more than four times the number of deer caught. How many rabbits did Katniss catch? - let x = number of deer Write an equation for deer plus squirrels plus rabbits equals total: - Write an expression for squirrels: - Write an expression for rabbits: - Write an expression for the total number of animals:
Answer:
She caught 10 rabbits
Step-by-step explanation:
Given
Represent Rabbits with R; Squirrels with S and Deer with D
[tex]S = 3D[/tex]
[tex]S = R - 5[/tex]
[tex]S + R+ D = 10 +4D[/tex]
Required
Determine the value of R
[tex]S + R+ D = 10 +4D[/tex]
Solve for R
[tex]R = 10 + 4D - D - S[/tex]
[tex]R = 10 + 3D - S[/tex]
Recall that [tex]S = 3D[/tex]
Substitute 3D for S
[tex]R = 10 + 3D - 3D[/tex]
[tex]R = 10[/tex]
Hence;
She caught 10 rabbits

The yoga instructor at Universe Fitness spent $1,925 on 200 items for the upcoming yoga seminar. He purchased yoga mats for $12.50 each, yoga towels for $8.00 each, and carrying cases for $10.00 each*. He purchased twice as many towels as mats.
Part A: Define variables and write a system of equations to represent the situation.
Part B: The instructor’s bookkeeper was auditing books. She noticed that in this transaction, the instructor purchased 200 items: 25 mats, 50 towels, and 125 carrying cases. Are the records accurate? Justify your answer.
Answer:
The auditing book is not accurate
Step-by-step explanation:
25($12.5)+50($8)+125($10)+= $1,925
$312.5 + $400 + $1,250 = $1,925
$1,962.5 not= to $1,925

Answer:
Step-by-step explanation:
Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the formula,
Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Slope of the line PQ passing through the two points P(-8, 2) and Q(4, 2) will be,
Slope '[tex]m_1[/tex]' = [tex]\frac{2-2}{-8-2}[/tex] = 0
Therefore, slope of the line PQ parallel to the x-axis = 0
Slope of the line MN passing through the points M(8, 6) and N(8, -8) is,
Slope '[tex]m_2[/tex]' = [tex]\frac{6+8}{8-8}[/tex] = ∞
Therefore, slope of the line MN parallel to y-axis is undefined.
Since, angle between the x-axis and y-axis is 90°,angle at the intersection point between the lines parallel to x and y axis will be 90°.
These lines are perpendicular to each other.
Answer:
B, slope = 0

walmart sells birthday cakes for $18. After 3 days, they markdown the cakes by 45%. What is the discounted price.
Answer:
The discounted price is $9.90.
Step-by-step explanation:
First, you need to find the amount of 45%.
Step 1- Convert the percent to a decimal.
[tex]\frac{45}{100} = 0.45[/tex]
Step 2- Multiply.
0.45×18= 8.10
Step 3- Subtract.
18-8.10= 9.90
So, the discounted price would be $9.90.
The discounted price is $9.90 for the birthday cakes.
