Step-by-step explanation:
If f (x) = x^2 + 3, evaluate f (-4).
=
A) -5
B) 19
C
11
D) -13
Answer: B) 19
Step-by-step explanation:
To solve this problem, simply plug in -4 for x:
[tex]f(x)=x^{2} +3\\f(x)=(-4)^{2} +3\\f(x)=16+3\\f(x)=19[/tex]
Hope it helps :) and let me know if you want me to elaborate/explain further
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
f(-4)= -13

Frank's Furters $6.24 /hr.
Harriet's Hair Styles $80 for 12 hours weekly
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.

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

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

Terry’s average driving speed for a 2 and a half hour trip was 58 mph. How far did Terry travel?
145 miles. lets see how i got this.
so first i took the 2.5 hour trip and the average speed, which was 58 mph (or 93.3 kph), and multiplied them together, because of the rule of d=rt.
sidenote: also if you want to find the speed, use r=d/t. also, for finding the time, use the t=d/r rule.
side-sidenote: i hope this answers your question and helps you in the future.
key: r= rate (mph or kph), d=distance, and t=time.

Step-by-step explanation:
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.

Given h(x) = 4x + 5 solve for when h(x) = 9 .
Answer:
3x = 5
Step-by-step explanation:
9x = 4x + 5
-4x -4x
3x = 5
Answer:
h(x) = 4x + 5 h(x) = 9
9 = 4x + 5 9 - 5 = 4 and 5 - 5 = 0
4 = 4x 4 divided by 4 equals 1
Answer is x = 1.
--------------------------------------------------------
Check your answer:
9 = 4x + 5
Input the 1 into the variable x's place in the equation.
9 = 4 X 1 + 5
And now solve.
4 X 1 + 5 = 9

Coordinate Planes
Properties of coordinate planesDomain is the set of x-values that can be inputted into function f(x) Range is the set of y-values that are outputted by function f(x)Interval Notation/Inequality NotationStep-by-step explanation:
According to the graph, we see that our x-value stretches from x = -2 to infinity. Since x = -2 is a closed dot, it is included in the domain:
[-2, ∞) or -2 ≤ x < ∞
According to the graph, we see that our y-value stretches from y = -4 to infinity. Since y = -4 is a closed dot, it is included in the range:
[-4, ∞) or -4 ≤ y < ∞

1) Cancel 3 on both sides
d≤−d
2) Subtract -d from both sides.
d+d≤0
3) Simplify d+d to 2d.
2d≤0
4) Divide both sides by 2.
