The table represents the function f (x) = 5x - 8.
Find f(-4):
f(-4)= 5(-4)-8
f(-4) = -28
Answers
Answer:
a=-18
b=7
c=27
Step-by-step explanation:
Given the function f (x) = 5x - 8 ,for different value of f(x)
f (-2)=-18
f (-2)=7
f (-2)=27
How to solve function?
A) for f (x) = 5x - 8 where f (-2).
⇒ f (-2) = 5x - 8
⇒ f (-2) = 5(-2) - 8
⇒ f (-2) = -10 - 8
⇒ f (-2) =-18
B) for for f (x) = 5x - 8 where f (3).
⇒ f (3) = 5x - 8
⇒ f (3) = 5(3) - 8
⇒ f (3) = 15 - 8
⇒ f (3) =7
C) for f (x) = 5x - 8 where f (7).
⇒ f (7) = 57 - 8
⇒ f (7) = 5(7) - 8
⇒ f (7) = 35- 8
⇒ f (7) =27

Answer:
They have a common numerator, that is 3. Therefore we can directly conclude that fraction with smaller denominator is greater of the two. Thus 3/5 is greater than 3/6. One way to compare the two fractions would be to both have the same denominator, so that numerators will be easily compared

The siding of a house is 2250 square feet. The siding needs two coats of paint. One quart costs $18 and covers 80 square feet. One gallon costs $29 and covers 320 square feet. What is the minimum cost of the paint needed to complete the job? How much paint is left over?
Answers
Answer:
Minimum cost needed = $221
Remaining quart paint = 7/8
Step-by-step explanation:
Let
x = number of 1 gallon paints
y = number of 1 quart paints
1 gallon covers 320 square feet
1 quart covers 80 square feet
Number of gallons paint needed = Total siding of the house / 320 square feet
= 2250 / 320
= 7.0312
Approximately to the nearest whole number
Number of gallons paint needed = 7 gallons
Total siding of the house covered by gallons = 7 gallons × 320 square feet
= 2,240 square feet
Siding of the house remaining = Total siding - Siding covered
= 2,250 - 2,240
= 10 square feet
1 quart covers 80 feet
Therefore, 1 quart will cover the remaining 10 square feet
A. The minimum cost of the paint needed to complete the job
Total cost = (Price of gallons × Quantity of gallons needed) + (price of quart × Quantity of quart needed)
= (29 × 7) + (18 × 1)
= 203 + 18
= $221
Minimum cost needed = $221
B. How much paint is left over
Recall
1 quart covers 80 square feet
And remaining siding to be covered = 10 square feet
That is,
10/80 = 1/8 of a quart paint used
Remaining quart paint = 1 - 1/8
= 7/8 quart paint

To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.

Find the inverse of the function f(x) = x3 + 5
Answers
Answer:
[tex]{f}^{ - 1} (x) = \sqrt[3]{x - 5} [/tex]Step-by-step explanation:
[tex]f(x) = {x}^{3} + 5[/tex]
To find the inverse of f (x) , equate f(x) to y
That's
y = f(x)
[tex]y = {x}^{3} + 5[/tex]
Next interchange the terms
That's x becomes y and y becomes x
[tex]x = {y}^{3} + 5[/tex]
Next solve for y
Send 5 to the other side of the equation
[tex] {y}^{3} = x - 5[/tex]
Find the cube root of both sides to make y stand alone
That's
[tex] \sqrt[3]{ {y}^{3} } = \sqrt[3]{x - 5} [/tex]
[tex]y = \sqrt[3]{x - 5} [/tex]
We have the final answer as
[tex] {f}^{ - 1} (x) = \sqrt[3]{x - 5} [/tex]

Step-by-step explanation:
First, we need to combine like terms,

simplify 5(a+6)−a+7a−18
Answers
Answer:
11a + 12
Step-by-step explanation:
For this problem, we will simply use the distributive property both forwards to gather all of the like terms, and then backward to simplify the like terms.
5 ( a + 6 ) - a + 7a - 18
= 5a + 30 - a + 7a - 18
= 5a - a + 7a + 30 - 18
= a ( 5 + -1 + 7 ) + 30 - 18
= a ( 4 + 7 ) + 12
= a ( 11 ) + 12
= 11a + 12
Hence, the simplification for 5(a+6)-a+7a-18 is 11a + 12.
Cheers.

Answers
Answer:
a: left = 14 feet
right = 18 feet
b: 18 is significant
c: absolute value is 18
Step-by-step explanation:
a)
The position of the diver on the left relative to the sea level is 14 feet.
The position of a diver on the right to sea level is 18 feet.
b)
integer 18 in part (a) is more significant.
c)
Absolute value is the distance and the zero on the number line.
Absolute value of |18| = 18
Absolute value of |14| = 14
Hence the most excellent absolute value is 18.
