Answer:

Step-by-step explanation

Since -2+-0.5= -2.5, we need to use a plus sign. Also, since we multiply both by 8.6, that is the answer.

Identify the y-intercept and slope of
the line.
y= 2x - 5

Answers

Answer:

y-intercept = -5

slope = 2

Step-by-step explanation:

Hello!

The y-intercept is always the y-coordinate when the line touches the y-axis. You can find this by plugging in 0 for x in the equation or choosing the last term in slope-intercept form.

Slope intercept form: y = mx + b

y = outputx = inputm = slopeb = y - intercept

Given this info, we can see that the slope, m, is 2, from our equation of y = 2x - 5, and the y-intercept is -5

What is a function?

Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

The composition of the two functions should render 'x" if one is the inverse of the other. That is, we need to find what f(g(x))  renders. Notice as well that the same verification could be done by examining g(f(x) .

Let's work with f(g(x).

[tex]f(g(x)=f(\dfrac{1}{5}+5)\\\\f(g(x)=5(\dfrac{1}{5}x+5)-25\\\\f(g(x)=x+25-25\\\\f(g(x)=x[/tex]

So we see that the composition of both functions indeed renders "x", and that way we have verified that one is the inverse of the other.

Joseph's hourly rate R, in dollars, is a function of t, the number of years he works at the grocery store.

Answers

Answer:

R(t)=10+0.50t

Step-by-step explanation:

Let t be the number of years.

We have been given that When Joseph first starts working at a grocery store, his hourly rate is $10.

 For each year he works at the grocery store, his hourly rate increases by $0.50.

So the hourly rates after t years will be 10 plus 0.50t.We can represent this information in an equation as: R(t)=10+0.50t


Therefore, the function  R(t)=10+0.50t represents Joseph's hourly rates after t years.

The answer to the question including equations is "None of these."

The value of x cannot be determined from the information given. The answer choices are all numbers, but they do not follow any obvious pattern. There is no mathematical operation that can be performed on the answer choices to arrive at a single value for x.

If we were given more information about the problem, such as the relationship between the answer choices, then we might be able to determine the value of x. For example, if we were told that the answer choices are all prime numbers, then we could rule out all of the answer choices except for 2 and 3. However, without more information, the value of x cannot be determined.

Here is a more detailed explanation of why the value of x cannot be determined:

The answer choices are all numbers, but they do not follow any obvious pattern. For example, the answer choices are not consecutive numbers, nor are they all even or odd numbers.

There is no mathematical operation that can be performed on the answer choices to arrive at a single value for x. For example, we cannot add, subtract, multiply, or divide the answer choices to get a single value for x.

Answers

Answer:

113.04

Step-by-step explanation:

Given:V = 324 cu

cmh = 9 cm

Since the formula for the volume of a cylinder is V = AreaBase*heightAreaBase = V/height = 324cu cm/ 9 cmAreaBase = 113.04 square centimetresTherefore, the area of the pillar in square centimeters is 113.04

The base area of the cylindrical pillar would be; 113.04 cm²

What is the Volume of a cylinder?

The volume of the cylinder is the product of the height, pie, and square of the radius.

v = πr²h

where, r = radius, h = height

Therefore,

v = 324π cm³

h = 9cm

Consider find the radius;

324π = 9πr²

r² = 324π  /9π

r² = 36

r = √36

r = 6 cm

Step-by-step explanation:

the perimeter (P) is the sum of the 3 sides of the triangle.

P = 4x² + 1 + 26x + 6 + x² + 10x ← collect like terms

  = 5x² + 36x + 7

to factor the expression, consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 5 × 7 = 35 and sum = 36

the factors are + 35 and + 1

use these factors to split the x- term

5x² + 35x + 1x + 7 ( factor the first/second and third/fourth terms )

= 5x(x + 7) + 1 (x + 7) ← factor out (x + 7) from each term

= (x + 7)(5x + 1) , then

P = (x + 7)(5x + 1) ← in factored form

Tina buys tickets to an amusement park. Adult tickets cost $18.50 each and children tickets cost $12.25 each. Tina has $280 to purchase both adult and children's tickets. If she purchases 6 children's tickets, determine algebraically the maximum number of adult tickets that Tina can purchase.

Answers

Answer: 11 adult tickets

Step-by-step explanation:

      First, we will write an equation. Let x be adult tickets and y be children tickets.

   $280 ≥ 18.5x + 12.25y

      Now I will graph it!

-> See attached

    If she bought 6 children's tickets, we can look to the y value of 6 (children's tickets) to find our maximum value of x (adult tickets).

    This means she can buy a maximum of 11 tickets because we will assume she cannot buy part of a ticket.

      She can buy 11 adult tickets.

In order to obtain the other side;

12/26 = 1560/26 = 60
