Answer:
g(f(x)) = 6x^2 -2
Step-by-step explanation:
Evaluate the expression using the given argument value.
g(f(x)) = g(2x^2 +1) = 3(2x^2 +1) -5
= 6x^2 +3 -5 = 6x^2 -2

Find X ( please explain how)
Answer:
90
Step-by-step explanation:
(5-2)x180= 540 formula to find the sum of interior angles of a polygon
180-70 = 110 lower right angle
180 -60 = 130 lower left angle
110+130+120+90= 450 all known angles sum
540-450 = 90 total minus known gives you x
Additive inverse of 400
Given:
A number is 400.
To find:
The additive inverse of 400.
Solution:
We know that the sum of a number and its additive inverse is 0.
If "a" is number and "b" is its additive inverse, then
[tex]a+b=0[/tex]
Let x be the additive inverse of 400. Then,
[tex]400+x=0[/tex]
Subtract both sides by 400.
[tex]400+x-400=0-400[/tex]
[tex]x=-400[/tex]
Therefore, the additive inverse of 400 is [tex]-400[/tex].

what is the answer to 4x+7=-2+4x
0=(-9)
Step-by-step explanation:
4x + 7 = -2 + 4x
4x + 7 = 4x -2
subtract 7 from both sides of the equation.
simplify your answer.
subtract 4x from both sides of the equation.
simplify your answer again.
4x + 7 = 4x -2
___-7 = 4x -7
4x __ = 4x -9
__4x = 4x -9
-4x = -4x -9
__0 = -9

Tom is told by his doctor that he needs to lose 15 pounds if Tom now it's 285 pounds then by what percentage should Tom's week decrease
Answer:
the percentage is 5.56%
Step-by-step explanation:
The computation of the percentage that the tom should decrease is shown below:
As Doctor said tom to reduce 15 pounds
As of now the tom has 285 pounds
So after considering the 15 pounds, it would be
= 285 - 15
= 270 pounds
Now the percentage that should be considered is
= (285 - 270) ÷ (270)
= 5.56%
Hence, the percentage is 5.56%

Sally has a car that accelerates at 5 m/s^2. If the car has a mass of 1000 kg, how much force does the car produce?
F=______
m=______
a=______
Answer:
You have to use the equation F=ma.
F: the force an object has (in this case the unknown)
M: the mass an object has (in this case 1000kg)
A: the acceleration an object has (in this case 5m/s^2)
when you plug in everything you should get F=5000N
Answer:
The answer is 5000 N (Newtons).
Explanation:
F=M*A
F=1000 kilograms * 5 m/s squared
F=5000 Newtons

Daniel says that more than half the students spent 2 1 2 hours or more on homework. Liz says more than half the students spent less than 2 1 2 hours on homework. Who is correct? Explain.
Answer:
Liz is correct
Step-by-step explanation:
Given
See attachment for complete question
Required
Who is correct? Daniel or Liz
From the attached data, we have:
[tex]Time: 1\frac{3}{4},\ 2\frac{1}{2},\ 2,\ 2\frac{3}{4},\ 1,\ 1\frac{3}{4},\ 1\frac{1}{4},\ 3,3\frac{1}{4},\ 3\frac{3}{4},\ 2,\ 2[/tex]
The total number of students is:
[tex]n = 12[/tex]
The data that represents [tex]2\frac{1}{2}[/tex] or more is:
[tex]Time: 2\frac{1}{2},\ 2\frac{3}{4},\ 3,3\frac{1}{4},\ 3\frac{3}{4}[/tex]
The frequency of this is 5
The frequency that represents [tex]2\frac{1}{2}[/tex] or less will be 7
This means that less than half spend [tex]2\frac{1}{2}[/tex] or more
and more than half spend [tex]2\frac{1}{2}[/tex] or more
Hence, Daniel is incorrect. Liz is correct

A hair salon uses 4 bottles of shampoo for every 3 bottles of conditioner.
The coordinate plane shows a graph of equivalent ratios.
Use the graph to find the number of bottles of conditioner that are used when 16 bottles of shampoo are used.
Answers
A 3 bottles of conditioner
B 6 bottles of conditioner
C 12 bottles of conditioner
D 20 bottles of conditioner
Answer:
I honestly think it is C.
Step-by-step explanation:
Since "4 bottles of shampoo for every 3 bottles of conditioner" is (4,3), I think the 16 is (16,12) on the graph. It might be worng, might be right. Just go for C.
Which rule is correct for translation 2 units right and 6 units down
Answer:
(x + 2, y - 6)
Step-by-step explanation:
When you go right or up it is in the positive.
When you go left or down it is in the negatives.
Answer:
[see below]
Step-by-step explanation:
Two units to the right is adding 2 together to the x value.
6 units down is subtracting 6 from the y-value.
The rule should be:
[tex](x,y)\rightarrow(x+2,y-6)[/tex]

M {-5,2} and N {5,2} are the endpoints of the segment MN on the coordinate plane what is the length of MN?
Answer:
Length MN = 10 unit
Step-by-step explanation:
Given: M {-5,2} and N {5,2} are the endpoints of the segment MN.
Length of line segment having co-ordinates as
[tex](x_1, y_1) and (x_2, y_2)[/tex]
is calculated as
[tex]D =\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
So plugging the values in above equation we get
[tex]D =\sqrt{(5+5)^2+(2-2)^2}[/tex]
D = 10 unit
Therefore, Length MN = 10 unit

a plumber charges $15 for a service call plus $20 per hour of service. Write an equation in slope-intercept form for the cost, y, after x hours of service. What will be the total cost for 8 hours of work?
Answer:
C= 25$ + 50$ * h
8 hours 425$
10 hours 525$
Step-by-step explanation:
Answer:
y = 20x + 15
The total cost for 8 hours of work will be $175
Step-by-step explanation:
To find the total cost for 8 hours of work, substitute the x in the equation with 8, and solve. 20 times 8 is 160. 160 + 15 is 175.

Students and adults purchased tickets for a recent school play. All tickets were sold at the ticket booth (discounts of any type) were not allowed.
Student tickets cost $8 each, and adult tickets cost $10 each. A total of $1,760 was collected. 200 tickets were sold.
a. Write a system of equations that can model the number of student and adult tickets sold at the ticket booth for the play.
b. Solve the system you create to find the exact number of student tickets sold and adult tickets sold.
c. Assuming that the number of students and adults attending would not change, how much more money could have been collected at the play if the student price was kept at $8 per ticket and adults were charged $15 per ticket instead of $10?
Answer:
a. (A + S = 200), (8S + 10A = 1760)
b. The school play sold 80 adult tickets, and 120 student tickets.
c. 400$ more would have been collected if the school charged 15$ per ticket instead of 10$
Step-by-step explanation:
a. To begin with, we can refer to S as student tickets, and A as adult tickets. We know that 200 tickets were sold, so we can say that (A + S = 200). We can also say that (8S + 10A = 1760).
b. We can twist the first system of equations and put one variable on the other side. It'll be (A = 200 - S). From there, we will substitute A in the second system of equations. The equation will be
(8S + 10(200 - S) = 1760)
Then you solve for S
(8S + 2000 - 10S = 1760)
-2S = -240
S = 120
Substitute for S in the first system of equations
A = 200 - 120
A = 80
or the second
8(120) + 10A = 1760
960 + 10A = 1760
10A = 800
A = 80
This means that the school play sold 80 adult tickets, and 120 student tickets.
c. (8S + 15A = X)
8(120) + 15(80) = X
X = 2160
2160 - 1760 = 400
400$ more would have been collected if the school charged 15$ per ticket instead of 10$
