graph f(x)=3x+4 and h(x)=f(x+3)
The standard form for expressing the equation of a straight line is
y = mx + b
Given the functions from the question f(x) = 3x + 4
If h(x) = f(x+3)
Replace x with x+3 in the function f(x) to have;
h(x) = 3(x+3) + 4
h(x) = 3x + 9 + 4
h(x) = 3x + 13

Let n = the number of lawn she mows.
Write an expression for the total amount she will charge for all of the lawns she mows.
will brainlist
Answer:
Kx20=N
Step-by-step explanation:
k with be the number multiplied by 20 and then N will be the answer
The expression for the total amount she charged can be represented as A = 20n.
What is an expression?A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.
For example 2x = 54
An expression is a mathematical proof of the equality of two mathematical expressions.
Given that,
She will charge $20 for every lawn
Number of lawns she mows = n
Total charge let's represent by A

Answer:
$1017.19
Step-by-step explanation:
First find the fraction of how much of Paulo's money is spent on his rent and car. Add 1/4 and 1/8, which is 3/8 because 1/4 = 2/8. Then multiply 3/8 by Paulo's monthly spending, which is $2712.50. Multiplying those numbers will get you $1017.1875. which you have to round up to $1017.19 because you can't spend three quarters of a cent.
Answer:
Asumming that you are rounding to the nearest hundreth:
1,017.19
Step-by-step explanation:
Find [tex]\frac{1}{8}[/tex] of 2,712.5 to find how much money Paulo spends on his car.
[tex]\frac{1}{8}[/tex] = .125
Multiply 2,712.5 by .125
2,712.5 × .125 = 339.0625 ≈ 339.06
Now, find [tex]\frac{1}{4}[/tex] of 2,712.5 to find how much paulo spends on his rent.
[tex]\frac{1}{4}[/tex] = .25
Multiply 2,712.5 by .25
2,712.5 × .25 = 678.125 ≈ 678.13
Add the two values together to get your answer
339.09 +
678.13
----------
1,017.19
(Another way to dolve this problem would be to find [tex]\frac{5}{8}[/tex] of 2,712.5 and subtract it from the origional value, 2,712.5)
Before her hike, Lara filled her water bottle with 4 cups of water. During the hike, she drank about 10 fluid ounces every hour. Afterward, she had about 12 fluid ounces left. How many hours did she hike?
Answer:
Lara hiked for 2 hours.
Step-by-step explanation:
1 cup = 8 ounces
4 cups = 32 ounces
32 - 10h = 12
10h = 20
h = 2
Lara hiked for 2 hours.
A cup contains 8 fluid ounces so the total number of ounces that Lara had before the hike was:
= Number of cups x fluid ounces per cup
= 4 x 8
= 32 fluid ounces
After the hike, Lara was left with 12 fluid ounces which means that she consumed:
= 32 - 12
= 20 fluid ounces
She drank 10 fluid ounces per hour so the total number of hours she hiked were:
= Number of fluid ounces consumed / Fluid ounces per hour
= 20 / 10
= 2 hours

The area of a rectangular pool is 7719m2. If the width of the pool is 83m, what is its length?
Answer:
The answer is 93 mStep-by-step explanation:
Area of a rectangle = l × w
l is the length
w is the width
From the question
Area = 7719 m²
width = 83 m
We have
[tex]7719 = 83l \\ \frac{83l}{83} = \frac{7719}{83} [/tex]
We have the final answer as
length = 93 mHope this helps you

a movie theater charges $8 for adults and $5 for children. If there were 40 people altogether and theater collected $272
Answer: You can put this solution on YOUR website!
let's call the number of adults a and the number of children c.
so the total adults plus the total children equals 40 or a+c=40 or c=40-a
also we know that 8a+5c=272
substituting c's value in the 1st equation into the 2nd equation we get
8a+5(40-a)=272---->lets distribute that left side---->8a+200-5a=272
now let's combine like terms on either side of the equals sign.
3a=72 a=24
so we have highlight%2824-adults%29
and c=40-a(24)=highlight%2816-children%29

Answer:
Alright! BTW, the answer to the question is D :)
Step-by-step explanation:
Reflecting across the x-axis, the x-coordinate ALWAYS remains the same, but the y-coordinate is transformed into its opposite. If you forget this, fold along the x line, and you should be able to figure it out.

57 is greater than x - 8
This is an inequality.
This is what the statement should look like: [tex]57 > x - 8[/tex]
Now, you can actually "properly" reverse these meaning the equality sign changes too. So basically you can mirror them.
The "mirrored" inequality expression would look like this: [tex]x - 8 < 57[/tex]
Now just like normal algebra, you can transpose these terms from 1 side to another and so, -8 would transpose to the right hand side and the operation would be the inverse or in this case, addition. The expression would look something like this: [tex]x < 57 + 8[/tex]
Add them up and you get: [tex]x < 65[/tex] :D

Dionna rode her skateboard at a speed of 10 miles per hour. Which statement is correct? *
If she covered 2.5 miles, she rode for 4 hours.
If she covered 2.5 miles, she rode for 0.25 hours.
If she covered 4 miles, she rode for 0.25 hours.
If she covered 4 miles, she rode for 4 hours.
Answer: A
Step-by-step explanation:
Because if she rode 10 mph means that she would ride 2.5 miles in 0.25 hours because if you divide 10 by 2.5 then you would get 0.25.

Stephen and Diana are traveling towards each other from points that are 276 miles apart. If Diana is traveling 4 mph faster than and they meet after 6 hours, how fast was each traveling?
Stephen is traveling______mph.
Diana is traveling_____ mph.
Answer:
Step-by-step explanation:
let speed of Stephen=x mph
speed of Diana=x+4
then
6x+6(x+4)=276
divide by 6
x+x+4=276/6=46
2x=46-4=42
x=42/2=21
Stephen is traveling at 21 mph.
Diana is traveling at 21+4=25 mph.
