Answer:
-6
Step-by-step explanation:
Hope I understand your "f(x) = 12 over the quantity of 4 x + 2" correctly
f(x) = 12 / 4x +2
Now so they want a f(-1), as u can see they substituted the x for - 1, therefor do that the same to the right side
f(-1) = 12/ 4(-1) + 2
f(-1) = 12 / - 4+2
= 12/ - 2
= - 6
8. Peter put 4/5 cup of chocolate
Chips into cookies batter. Samantha put 7/8 cup into hers. Whose batter contains more chips? How do you know?
Answer: Samantha
Step-by-step explanation:
Two ways you could solve this percents or fractions.
Percents
Peter: 4/5 = 80%
Samantha: 7/8 = 87.5%
Fractions
Set the denominator equal to each other
the common denominator would be a multiples to both 5 and 8 which is 40.
Peter: 4/5 = 32/40 because 5 times 8 is 40 and what you do to the denominator you do to the numerator so 4 times 8 is 32.
Samantha: 7/8 = 35/40 because 8 x 5 = 40 and 7 x 5 = 35.
Then compare and 35/40 is greater so Samantha.

Amaya wants to jog 8 miles this week.She jogged 2 1/2 miles on Monday and 3 2/5 miles on wednesday. How many miles does Amaya still need to jog?
Answer:
2 1/10 miles.
Step-by-step explanation:
8 - (2 1/2 + 3 2/5)
= 8 - (5/2 + 17/5)
= 8 - (25/10 + 34/10)
= 8 - 59/10
= 80/10 - 59/10
= 21/10
= 2 1/10 miles.

If the perimeter of the triangle below is 120 inches, what is the length of AC?
Answer:
54
Step-by-step explanation:
4x + 1 + 4x + 1 + 7x - 2 = 120
x=8
7(8) - 2 = 54
The length of the side AC is 54 inches.
Given that, the perimeter of the triangle is 120 inches.
We need to find the length of AC.
What is the perimeter of a triangle?The perimeter of a triangle is defined as the total length of its boundary. It is the sum of all three sides of the triangle.
The given triangle ABC is an isosceles triangle, so AC=BC
Now, AB+AC+BC=120
⇒4x+1+7x-2+4x+1=120
⇒15x=120
⇒x=8
Then, AC=7x-2=7×8-2
=56-2=54 inches
Therefore, the length of the side AC is 54 inches.

If ray AB is the angle bisector of Im in geometry freshman year and I have absolutely no idea how to solve this I’m taking notes as I go so please help me!!
Answer:
x=8
Step-by-step explanation:
Angle bisector means it cute the big angle into two equal, smaller angles (like cutting a piece of cake in half)
therefore, you can set both smaller angles equal to each other, then solve for x
4x+1=33 Subtract 1 from both sides
4x=32 Divide both sides by 4
x=8

The school that Linda goes to is selling tickets to the annual talent show. On the first day of ticket sales the school sold 4 senior citizen tickets
and 5 student tickets for a total of $102. The school took in $126 on the second day by selling 7 senior citizen tickets and 5 student tickets.
What is the price each of one senior citizen ticket and one student ticket?
Answer:
8 & 14
Step-by-step explanation:
Let
Cost of senior tickets be x and students be y
In day 1
4x + 5y = 102
In day 2
7x + 5y = 126
Subtract both
7x + 5y - (4x + 5y) = 126 - 102
7x + 5y - 4x - 5y = 24
7x - 4x = 24
3x = 24
x = 24/3
x = 8
From 1
4(8) + 5y = 102
32 + 5y = 102
5y = 102 - 32
5y = 70
y = 70/5
y = 14

Solve each equation 3m-3/5=2m-1/2
Answer:
m= 1/10
Step-by-step explanation:
1. Move the terms so that will be 3m - 2m=-1/2 + 3/5
2. Subtract the m values so that will be 3m - 2m= 1 or m
3. Calculate the sum.
4. So the answer will be m= 1/10. M because we subtracted 2 from 3 which make us 1 so we say it m and 1/10 by doing 1/2 + 3/5.
Answer:
Step-by-step explanation:
3m - 3/5 = 2m - 1/2
3m - 2m = 3/5 - 1/2
m = 0.1
i need help algebra
Answer:
A. the slope value is 1/4
B. 0
C. y = 1/4x
Step-by-step explanation:
A: the slope can be calculated with the formula
[tex]m = \frac{rise}{run} = \frac{y2 - y1}{x2 - x1} [/tex]
m is the slope
(x1, y1) is your first coordinate point (any point will work)
(x2, y2) is your second coordinate point (any point will work)
Plug in your values, in this case I chose (0,0) and (4,1) as the two coordinates:
[tex]m = \frac{y2 - y1}{x2 - x1} = \frac{1 - 0}{4 - 0} = \frac{1}{4} [/tex]
B: the y-intercept is the y-coordinate of where the graph touches the y-axis and in this case the coordinate is (0,0) where the y coordinate is 0.
C:
the equation of the graph is y = mx + b.
m is the slope = 1/4
b is the y-intercept = 0
Therefore the equation is y = 1/4x

Find FH on number 2 please
Answer:
FH = 7
Step-by-step explanation:
Look at the figure below.
In this problem, we use twice the definition of a point between two points.
Point F is between points E and G, so
EF + FG = EG
Point G is between points F and H, so
FG + GH = FH
From point F being between points E and G, we have:
EF + FG = EG
We are shown that EF = 8 and EG = 10.
8 + FG = 10
FG = 2
From point G being between points F and H, we have:
FH = FG + GH
We calculated FG = 2, and we are shown that GH = 5.
FH = 2 + 5
FH = 7

Order the racers from first place to fifth place based on the clues.
Susan finished the race in second place.
The swimmers who placed first and fourth have names that start with the same letter.
Maria finished immediately after Janice.
Jennifer finished before Emily.
Answer:
Jennifer - 1st
Susan - 2nd
Emily - 3rd
Janice - 4th
Maria - 5th
Step-by-step explanation:
Susan is 2nd.
Places 1, 3, 4, and 5 are left.
Janice and Jennifer both start with J. None of the other swimmers start with the same first letter. One is 1st and one is 4th.
Since Maria finished immediately after Janice, and Janice must be 1st or 4th, Janice can't be first since 2nd place is already taken. This means that Janice is 4th and Maria is 5th.
Places 1 and 3 are left.
We know Jennifer is 1st or 4th and since 4th is taken, Jennifer is first.
Place 3 is left.
Emily must be 3rd since that is the only spot left.
