Answer:
D. -13
Step-by-step explanation:
If you substitute -4 in for x you get -4^2+3, so when you simplify you get -16+3 which equals -13.
f(x)=x^2+3
f(-4)= -4^2+3
f(-4)= -16+3

Suppose M is the midpoint of Segment AB, P is the midpoint of Segment AM, and Q is the midpoint of segment PM.
If a and b are the coordinates of A and B, find the coordinates of M, P, and Q in terms of a and b.
The coordinates of M, P and Q in terms of a and b are [tex]M = \frac{1}{2}\cdot a + \frac{1}{2}\cdot b[/tex], [tex]P = \frac{3}{4}\cdot a + \frac{1}{4}\cdot b[/tex] and [tex]Q = \frac{1}{8}\cdot a - \frac{1}{8}\cdot b[/tex], respectively.
In this question we are going to use definitions of vectors and product of a vector by a scalar. Based on the information given on statement, we have the following vectorial formulas:
Location of M
[tex]\overrightarrow{AM} = \frac{1}{2}\cdot \overrightarrow{AB}[/tex]
[tex]\vec M - \vec A = \frac{1}{2}\cdot \vec B - \frac{1}{2}\cdot \vec A[/tex]

[tex]M = \frac{1}{2}\cdot a + \frac{1}{2}\cdot b[/tex]
Location of P
[tex]\overrightarrow{AP} = \frac{1}{2}\cdot \overrightarrow{AM}[/tex]
[tex]\vec P - \vec A = \frac{1}{2}\cdot \vec M - \frac{1}{2}\cdot \vec A[/tex]
[tex]\vec P = \frac{1}{2}\cdot \vec A +\frac{1}{2}\cdot \vec M[/tex]
[tex]\vec P = \frac{3}{4}\cdot \vec A + \frac{1}{4}\cdot \vec B[/tex]
[tex]P = \frac{3}{4}\cdot a + \frac{1}{4}\cdot b[/tex]
Location of Q
[tex]\overrightarrow{QM} = \frac{1}{2}\cdot \overrightarrow{PM}[/tex]
[tex]\vec M - \vec Q = \frac{1}{2}\cdot \vec M - \frac{1}{2}\cdot \vec P[/tex]
[tex]\vec Q = \frac{1}{2}\cdot \vec P - \frac{1}{2}\cdot \vec M[/tex]
[tex]\vec Q = \frac{1}{2}\cdot \left(\frac{3}{4}\cdot \vec A + \frac{1}{4}\cdot \vec B\right) -\frac{1}{2}\cdot \left(\frac{1}{2}\cdot \vec A + \frac{1}{2}\cdot \vec B\right)[/tex]

Babysitting $250 a month for 10 hours after school a week. (Assume 4 weeks is a month.)
Which job has the highest hourly pay?
Frank's Furters
Two of them are tied.
Babysitting
Harriet's Hair Styles
Answer:
Harriet's Hair Styles
Step-by-step explanation:
Frank's Furters $6.24 /hr
Harriet's Hair Styles $80 for 12 hours weekly
$80 / 12 hr = $6.66/hr
Babysitting $250 a month for 10 hours after school a week. (Assume 4 weeks is a month.)
$250 / (4 wk * 10 hr/wk) = $250/ 40 hr = $6.25/hr
Answer: Harriet's Hair Styles
Harriet's Hair Styles has the highest hourly pay at $6.67 per hour.
To determine which job has the highest hourly pay, we need to calculate the hourly wage for each job based on the information provided.
Frank's Furters: $6.24 per hour.
Harriet's Hair Styles: $80 for 12 hours weekly.
Babysitting: $250 a month for 10 hours after school a week.
Let's calculate the hourly wage for each job:
Frank's Furters: $6.24 per hour.
Harriet's Hair Styles: $80 for 12 hours weekly
= $80 / 12 hours
= $6.67 per hour.
Babysitting: $250 a month for 10 hours after school a week
= $250 / (4 weeks x 10 hours)
= $6.25 per hour.
Hence, Harriet's Hair Styles has the highest hourly pay at $6.67 per hour.

Solve the equation: 8 = 1/3(a+5)
Answer:
a=19
Step-by-step explanation:
8=1/3(a+5) by dividing both sides by 1/3
24 = a+5 get 5 to other side with oposite sign
24-5 = a
a = 19
Answer:
a = 19
Step-by-step explanation:
8 = [tex]\frac{1}{3}[/tex] ( a + 5) ← multiply both sides by 3 to clear the fraction
24 = a + 5 ( subtract 5 from both sides )
19 = a

The solution of the linear equation [tex]\sqrt{x+3} = 12[/tex] for the variable, x is 141.
Two algebraic expressions separated by an equal symbol in between them and with the same value of the expression are called equations.
Example = 2x +4 = 12
here, 4 and 12 are constants and x is variable
The solution of the equation can be calculated as:
[tex]\sqrt{x+3} = 12[/tex]
Squaring both side,
[tex]x+3 = (12)^2[/tex]
x+3 = 144
Subtract 3 from both the sides,
x = 141

M is the midpoint of PQ. MQ = 5x + 8 and PQ = 6x + 56, find PM.
(4 Points)
Enter your answer
If M is the midpoint of PQ. MQ = 5x + 8 and PQ = 6x + 56, then PM = 58
Since M is the midpoint of PQ
PM + MQ = PQ................(*)
Given:
PQ = 6x + 56
MQ = 5x + 8
Substitute PQ and MQ into equation (*)
PM + (5x + 8) = 6x + 56
Collect like terms
PM = 6x + 56 - (5x + 8)
Expand the equation using the distributive rule
PM = 6x + 56 - 5x - 8
PM = 6x - 5x + 56 - 8
PM = x + 48.........(**)
Equate MQ and PM
MQ = PM
5x + 8 = x + 48
Collect like terms
5x - x = 48 - 8
4x = 40
Divide both sides by 4
4x / 4 = 40/4
x = 10
Substitute x = 10 into equation (**)
PM = x + 48
PM = 10 + 48
PM = 58

If R is the midpoint of QS, QR = 6x – 51 and RS = 2x – 7, find QS.
Answer:
QS = 30
Step-by-step explanation:
Since R is the mid point QR = RS
Given QR = 6x – 51 and RS = 2x – 7 then
6x – 51 = 2x – 7, isolate like terms
6x -2x = 51 -7 , combine like terms
4x = 44, divide both sides by 4
x = 11
QS = QR + RS
QS = 6x -51 +2x -7 , combine like terms
QS = 8x - 58, substitute x= 11 in the equation
QS = 8*11 -58, multiply 8 and 11
QS = 88 -58
QS = 30
Bert made 3 batches of his uncle's signature spicy wing sauce for a barbecue last weekend.
He didn't want the sauce to be too spicy, so he tweaked the recipe, reducing the amount of
hot sauce he put in each batch by 2 ounces. Bert used 24 ounces of hot sauce in all to make
the wing sauce.
Which equation can you use to find u, the amount of hot sauce Bert's uncle usually puts in
each batch of spicy wing sauce?
3(u - 2) - 24
2(0 - 3) - = 24
3u - 2 = 24
2u - 3 = 24
How much hot sauce does Bert's uncle usually put in each batch of spicy wing sauce?
Write your answer as a whole number or a simplified fraction.
ounces
Algebraic equations are equations that have coefficients and unknown variables in them.
The equation to show how many ounces of spicy sauce Bert's uncle usually put in is given as: 3(u - 2) = 24
The amount of hot sauce Bert's uncle usually puts in each batch of spicy wing sauce is 10 ounces.
a) We are told in the question that Bert made 3 batches of his uncle's spicy sauce. He reduced the amount of hot sauce and used 2 ounces in each batch. He used 24 ounces of hot sauce in all to make the wing sauce.Let's represent each ounce of hot sauce as u
Hence, the equation to show how many ounces of spicy sauce Bert's uncle usual put in is given as:
3(u - 2) = 24
b) How much hot sauce does Bert's uncle usually put in each batch of spicy wing sauce?The amount of hot sauce Bert's uncle puts in the spicy wing sauce
3(u - 2) = 24
3u - 6 = 24
Collect like terms
3u = 24 + 6
3u = 30
Divide both sides by 3
u = 30/3
u = 10
Bert's uncle puts 10 ounces of hot sauce in the spicy wing sauce.

The circle graph shows the results of a survey. Of those surveyed, 200 said yes. About how many people were surveyed?
Answer:
250 people
Step-by-step explanation:
let's first look for the missing 20%,
one way you can solve this is by cross multiplication:
since 80% is 200 then 80% = 200
and we know 20% is x then 20% = x (we use x because we don't know the amount of people)
so then we set it up:
[tex]\frac{x}{20}[/tex] × [tex]\frac{200}{80}[/tex]
now we cross multiply:
80x = 4000
= x = 50
now we need to find how many people were surveyed so we do:
200 + 50 = 250
250 people were surveyed
