Half of a number decreased by 8 is 3

Answers

Answer 1

Answer:
With the Brainly help you've gotten in the last 15 minutes or so,
you should be able to do this one now.

The mystery number . . . . . . . M
Half of it . . . . . . . . . . . . . . . . 1/2 M
Half of it decreased by 8 . . . 1/2 M - 8

You said that's 3 .
So the equation you have to solve is

      1/2 M - 8 = 3

Add 8 to each side: 1/2 M   = 11

Multiply each side by 2 : M   = 22

This is easier than the last one we ( I ) did.

Write an equation in standard form for a line that passes through (4,1) & (5,7)

Answers

y = mx + b

First equation 1 = m(4) + b, bring everything to one side m(4) + b - 1 = 0
Second equation 7 = m(5) + b, bring everything to one side m(5) + b - 7 = 0

Set them equal to each other,

m(4) + b - 1 = m(5) + b - 7

If you bring the b over to the left hand side it becomes

m(4) + b - b - 1 = m(5) - 7

m(4) - 1 = m(5) - 7

Solve for m

6 = m

Plug m = 6 into either equation from the beginning,

m(4) + b - 1 = 0

6(4) + b - 1 = 0

24 + b - 1 = 0

b = -23

Knowing m and b we can now make an equation

y = mx + b

y = 6x -23 Final answer

Justin ordered 6 pizzas. Each pizza costs $10.95. How much will he need to pay?

Answers

Answer:

$65.7

Step-by-step explanation:

Eachpizza costs $10.95.

So to get the amount of 6 pizzas, it has to be multiplied by the amount of each pizza.

That is, 6 × $10.95 =$65.7

=$65.7 is the amount he needs to pay.

Answer: 65.7

Step-by-step explanation: you do 6 x 10.95 = 65.7

There are two types of trees: elm and pine. There should be at least 16 total trees but no more than 30. The ratio of elm trees to pine trees will be 3:2. Give an example of how many trees of each type the designer could plan for the park. Show or explain how you found your answer.

Answers

Answer: 18 pine trees / 12 elm trees

Step-by-step explanation:

To meet the requirement of at least 16 but no more than 30 trees with a 3:2 ratio of elm to pine trees, we can choose:

Elm Trees: 3x

Pine Trees: 2x

Where x is a positive integer. To stay within the given constraints:

3x + 2x ≥ 16 (at least 16 trees)

5x ≥ 16

x ≥ 16/5

x ≥ 3.2

We need to find the largest integer value for x while staying below 30 (no more than 30 trees). Since x must be an integer, the largest valid value for x is 6 (as 7 would exceed 30).

So, for the example:

Elm Trees = 3x = 3 * 6 = 18

Pine Trees = 2x = 2 * 6 = 12

In this case, there would be 18 elm trees and 12 pine trees, totaling 30 trees, which falls within the range of at least 16 but no more than 30 trees and maintains the 3:2 ratio of elm to pine trees.

Which of the following represents the graph of f(x) = 4x − 2? graph of exponential rising up to the right, through the point 0, negative 3
graph of exponential rising up to the right, through the point 0, 1
graph of exponential rising up to the right, through the point 0, 3
graph of exponential rising up to the right, through the point 0, negative 1

Answers

The graph of the function
f(x) = 4^x - 2
has a constant value from negative infinity to negative 3 and then increases exponentially to positive infinity

Therefore, the answer from the choices is:
graph of exponential rising up to the right, through the point 0, negative 3
