Step-by-step explanation:
simplify
−4x^2 + 10 + 2x^2 −5x −7
= −4x^2 + 10 + 2x^2 + −5x +−7
combine like terms:
= −4x^2 + 10 + 2x^2 + −5x + −7
= (−4x^2 + 2x^2) + (−5x) + (10+ −7)
= −2x^2 + −5x + 3
Answer:
-2x^2-5x+3
Step-by-step explanation:
-4x^2+2x^2=-2x^2 10-7=3
Is it ever possible for adjacent angles to also be vertical? Why or why not?
Yes
Step-by-step explanation:
Because adjacent angles are vertical angles since they both have intersecting lines

Answer:
Jump discontinuity at x = -2 & infinite discontinuity at x = 0.
Step-by-step explanation:
Hi again,
In this example, we see that there is a jump discontinuity at x = -2 because the line hypothetically "jumps" from y = 2 to y = 0. (just a way to remember these terms)
In addition, there is an infinite discontinuity at x = 0 because the green function will become infinitely close to x = 0 but never crosses nor touches it.
Hope this explanation was helpful. Cheers.

For 5 months Tomas buys 4 boxes of crunchy granola bars and 3 boxes of chewy granola bars for his family.
Crunchy bars come in x bars and chewy granola bars come in y bars. Which two expressions can be used to
show the total number of granola bars Tomas buys.
x bars <4> and y bars come in <3>
Answer:
5(4x + 3y) = 20x + 15y
Step-by-step explanation:
The matter of months in which in this case is 5 months is the coefficient.
The amount of boxes per month is important information. We don't know how many bars are in each box. EACH is a key word for multiplying. If we want to know quickly how many bars are in 4 boxes (or 3) of the granola bars. We can simply multiply the amount of bars for each box with the amount of boxes. Since we don't know the amount of bars there are in each box we are going to use a variable. so it would look like this- 4x + 3y BUT we need to add the coefficient. Now rewrite the expression. 5(4x + 3y)
We can use the distributive property to generate an equal expression.

Solve the system by substitution.
x= −8y
−x+y= 18
=(_,_)
Answer:
(-16,2)
Step-by-step explanation:
x= −8y
−x+y= 18
substitute for x:
-(-8y) + y = 18
8y + y = 18
9y = 18
divide both sides by 9:
y = 2
x = -8(2) = -16

If 3x-7=5x, what is 6x?
Answer:
6x = - 21
Step-by-step explanation:
Given
3x - 7 = 5x ( subtract 3x from both sides )
- 7 = 2x
Then
6x = 3 × 2x = 3 × - 7 = - 21
A cylinder has a height of 4 yards. Its volume is 452.16 cubic yards. What is the radius of the cylinder?
Answer:
Step-by-step explanation:
V = π times r^2 times h (height)
452.16 = 3.14 times r^2 times 4
Multiply 3.14 times 4
452.16 = 12.56 times r^2
Divide 452.16 by 12.56.
452.16 / 12.56 = 36
36 = r^2
The square root of 36 is 6.
So the radius of the cylinder is 6 yards^3.

if f(x) =2x-6 then f(1)=
Answer:
f(1) = -4
Step-by-step explanation:
Given that,
f(x) = 2x-6
We need to find the value of f(1).
Put x = 1 in the above expression.
f(1) = 2(1)-6
= 2-6
= -4
So, the value of f(1) is equal to -4.
At a bake sale, the cost, C or buying n pies is C = 7n. If one customer buys $84
worth of pies, how many did they buy? Use proper solution form.
C = 7n
fill in the missing numbers and you get
84 = 7n
which means you can divide 84 by 7 to get n
84/7 = n
n = 12
12
Answer: 12 pies
Step-by-step explanation:
C=7n
C=7(12)
C=84
Customer bought 12 pies

A group of seven people went to an amusement park and spent $234 on tickets. If
a child's ticket costs $28 each and an adult ticket costs $37.50 each, how many
adult tickets and how many child tickets were purchased?
Answer:
3 adult tickets and 4 child tickets were bought.
Answer:
4 adult tickets and 3 child tickets
Step-by-step explanation:
So doing 234/7 gives you 33.428... which means its not all just children or adults. (I know that's common sense but it's best to do this anyway to further justify your answer)
The total cost for all 7 people shows that there must be an even amount of adult tickets to end up with a whole number so either 2, 4, or 6 adults.
2 adults = $75
4 adults = $150
6 adults = $225
Now we can use these possibilities to figure out if the left over child tickets added to the adult tickets would equal $234. (quick note: I am using # to show that it doesn't equal $234)
If 2 adults = $75, 5 children = $140, $140+$75 = $215 # $234
If 4 adults = £150, 3 children = $84, $84+$150 = $234
Now because we have already figured out that it would be 4 adult tickets and 3 child tickets, we wouldn't need to figure out 6 adult tickets and 1 child ticket, but, again, this would justify your answer and help to secure your marks.
If 6 adults = $225, 1 child = 28, $28+$225 = $253 # $234
I hope this answer helped you out and if you have any questions I'd be happy to help :)
