Given the following function, find f(-4), f(0), and f(4).
f(x) = x + 2

f(-4)=
f(0) =
f(4)=

Answers

Answer 1

Answer:

-2, 2, 6

Step-by-step explanation:

f(-4)= -4+2=-2

f(0)=0+2=2

f(4)=4+2=6

Substitute x for the number in parentheses

Answer 2

The values of f(-4), f(0), and f(4) are -2, 2, and 6 after plugging the value of x: -4, 0, and 4.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

The function f(x) = x + 2

To find the value of f(-4):

Plug x = -4 in the function:

f(-4) = -4 + 2 = -2

To find the value of f(0):

Plug x = 0 in the function:

f(0) = 0 + 2 = 2

To find the value of f(4):

Plug x = 4 in the function:

f(4) = 4 + 2 = 6

Thus, the values of f(-4), f(0), and f(4) are -2, 2, and 6 after plugging the value of x: -4, 0, and 4.

Mark starts a rock climb when he is 1 mile above sea level. He can climb at the rate of 1.5 miles per hour. Which of the following functions would express Mark's height above sea level over time?
A. f( x) = 1.5 x
B. f( x) = 2.5 x
C. f( x) = 1 + 1.5 x

Answers

Answer:

C.

Step-by-step explanation:

Its C because you start out at 1 mile above sea level, then each time Mark climbs he goes up 1.5 miles per hour. f(x)= 1(starting point) + 1.15x (miles per hour).

It would be C because the 1.5x represents the miles per hour since that changes and you would add 1 because he is 1 mile above sea level

A line has a slope of
1/4
and passes through the point (0.2,
4/5


Find the value of b, the y-intercept.


b = ???

Answers

Answer:

b = 3/4

Step-by-step explanation:

Using point slope: y - y1 = m(x - x1).

Substitute your given slope, given point, and subsitute 0 in for x and solve for y since the y intercept is the y value when x = 0.

0.2 = 1/5, so 1/5 * 1/4 = 1/20

Therefore: y - 4/5 = 1/4(0 - 0.2) → y - 4/5 = -1/20 → y = 4/5 - 1/20 → 15/20 → 3/4

b = 3/4

Using point slope: y - y1 = m(x - x1).

Substitute your given slope, given point, and subsitute 0 in for x and solve for y since the y intercept is the y value when x = 0.

0.2 = 1/5, so 1/5 * 1/4 = 1/20

Therefore: y - 4/5 = 1/4(0 - 0.2) → y - 4/5 = -1/20 → y = 4/5 - 1/20 → 15/20 → 3/4

Naomi is planning a holiday. The hotel costs $80 every night she stays and the flight costs $250,
She has a budget of $700 for her hotel and flight. How many nights will she be able to stay at
the hotel without going over her budget?

Answers

Answer:

5 nights

Step-by-step explanation:

# of nights= budget - flight {divided by} price per night

                 = 700$ - 250$ {divided by} 80$

                 = 450$ {divided by} 80$

                 = 5.6

                 =5 (round down)

Answer:

she will be able to stay 5 nights at the hotel

the second awnser and the third awnser.

Step-by-step explanation:

if the flight costs $250 and a night at the hotel costs $80 then 5 nights would equal $400 and then you would add the flight costs and it would equal $650. it can't be 6 nights cause she would go over her budget.

POLYNOMIALS QUESTION!!!

Answer:

The new area of the smaller rectangle is 16 - x² units²

Step-by-step explanation:

The dimensions of the small rectangles are 2 + x and 2 - x

∵ The length of the small rectangle is 2 + x units

∵ The length is adding by 2 units

The new length = 2 + x + 2 = 4 + x units

∵ The width of the small rectangle is 2 - x units

∵ The width is adding by 2 units

The new width = 2 - x + 2 = 4 - x units

Area of the rectangle = length × width

∴ The new area of the smaller rectangle = (4 + x) × (4 - x)

→ Simplify it by multiplying the 2 brackets

∵ (4 + x)(4 - x) = (4)(4) + (4)(-x) + (x)(4) + x(-x)

∴ (4 + x)(4 - x) = 16 + (-4x) + 4x + (-x²)

→ Remember (+)(-) = (-)

∴ (4 + x)(4 - x) = 16 - 4x + 4x - x²

→ Add the like terms

(4 + x)(4 - x) = 16 - x²

The new area of the smaller rectangle is 16 - x² units²

Jeremiah dad Ordered five large pepperoni pizzas in each large cheese pizzas for the birthday party he spent a total of 144 on pizza if a pepperoni pizza cost 12 right and solve a linear equation to find the cost of a cheese pizza

Answers

This question is incomplete because part of the information is missing; here is the complete question:

Jeremiah's dad ordered 5 large pepperoni pizzas and 8 large cheese pizzas for the birthday party. He spent a total of $144 on pizza. If a pepperoni pizza costs $12, write and solve a linear equation to find the cost of a cheese pizza.

The answer to this question is $10.50

Explanation:

The first step to solve this problem is to write a linear equation. In this, the unknown should be represented by an x, and other variables should be included using correct mathematical symbols. Here is the process:

1. In an equation there is always an equality symbol = and mathematical expressions on both sides.

2. In this situation, the value after the = symbol should be 144 or the total spend on pizzas.

3. The values missing should be expressed as 5 (12) + 8x because there are 5 pepperoni pizzas and each of these costs $12; also, this should be added to the 8 cheese pizza and x represents the missing value (the price of a cheese pizza.)

4. Solve the equation

5 (12) + 8x = 144 -Simplify using multiplication

60 + 8x = 144 - Solve by moving the number to the right side and changing the symbol

8x = 144 - 60

8x = 84

x = 84 ÷ 8

x = 10.5
