Answer:

h(-2) = 32

[tex]\displaystyle\mathsf{h(\frac{20}{7})=-2}[/tex]

Step-by-step explanation:

Given the linear function, h(x) = -7x + 18:

In order to evaluate h(-2), simply substitute the value of the given input, x = -2, into the function.

h(x) = -7x + 18

h(-2) = -7(-2) + 18

h(-2) = 14 + 18

h(-2) = 32

Therefore, the output value when x = -2 is: h(-2) = 32.

This particular problem asks us to find the corresponding domain (x-value) given the range value of y = -2.  

Substitute the value of y = -2 into the function to solve for the value of x:

h(x) = -7x + 18

-2 = -7x + 18

Subtract 18 from both sides:

-2 - 18 = -7x + 18 - 18

-20 = -7x

Divide both sides by -7 to solve for x:

[tex]\displaystyle\mathsf{\frac{-20}{-7}\:=\:\frac{-7x}{-7} }[/tex]

[tex]\displaystyle\mathsf{x\:=\frac{20}{7}}[/tex]

Therefore, the value of x when h(x) = -2 is:   [tex]\displaystyle\mathsf{h(\frac{20}{7})=-2}[/tex].

Answer:Therefore, the domain is restricted to non-negative values of x so that the function values will be defined. The variable x is often referred to as the independent variable, while the variable y is referred to as the dependent variable

Answer:

40

Step-by-step explanation: Make a proportional relationship. Make 25% into a fraction, 25/100. Then make 10 into a fraction using a variable. For example 10/p. Then cross multiply. 100x10=1000. Divide 1000 by 25 and the answer would be 40.

Answer:

1st number: 37

2nd number: 22

Step-by-step explanation:

let n = 1st number

let n-15 = 2nd number

n+(n-15)=59

collect like terms: 2n-15=59

add 15 to both sides

2n=74

divide both sides by 2

n=37

n-15=22

4batches= 5 1/3 cups

Step-by-step explanation:

Again, basic math.... You should actually be trying to learn it instead of getting people online to do it.

Step-by-step explanation:

Change the equation to the general form [tex]Ax + By + C = 0[/tex].

[tex]y - 15 = - 6(x + 7) \\ y - 15 = - 6x - 42 \\ 6x + y - 15 + 42 = 0 \\ 6x + y + 27 = 0[/tex]

The slope

[tex] = - \frac{A}{B} [/tex]

[tex] = - \frac{6}{1} [/tex]

[tex] = - 6[/tex]

Answer:  Slope is -6

Step-by-step explanation:

We want to rearrange the equation to the form of y=mx+b, where m is the slope and b the y-intercept.

y−15=−6(x+7)

y−15=−6x-42

y=−6x-42+15

y = -6x - 27

The slope is -6

Answer:

x = 6/5

Step-by-step explanation:

x-4        4x-9

------ = ----------

2             3

Using cross products

3 * (x-4) = 2 ( 4x-9)

Distribute

3x-12 = 8x-18

Subtract 3x from each side

3x-12-3x = 8x-18-3x

-12 = 5x-18

Add 18 to each side

-12+18 =5x-18+18

6 = 5x

Divide by 5

6/5 = 5x/5

6/5 =x

Answer:

Answer:

Do you mean 3/8 times 2/5? It equals 3/20

Step-by-step explanation:

So multiple the top numbers together for the top result and multiple bottom numbers for bottom result. 3 times 2 equal 6, 8 times 5 equal 40. the result is 6 over 40. After simplifying, we have 3 over 20 (dividing both 6 and 40 by 2)

Answer:

B. X > 8

Step-by-step explanation:

when dividing a negative denominator, you are flipping the sign. if the denominator doesn't have a negative sign, the sign isn't flipped.

steps:

subtract 30 by -18.

Soon you receive -48. Divide that by -6.

The signs soon flip giving you X> 8

Answer:

B) (4x+3)(16x²-12x+9)

Answer:

He volunteered 10 hrs 15 min on average.

Step-by-step explanation:

The first week: 8 hrs

The second week: 12 hrs

The third week: 12 hrs

The fourth week: 9 hrs

8 + 12 + 12 + 9 = 41 hrs total

41 hours/4 weeks = 10.25 hrs (10 hrs 15 min)

Answer: 10.25 hours/week (On average, William volunteered 10.25 hours per week during these four weeks)

Step-by-step explanation:

To find an average, you need to add up each entity:

8+12+12+9=41

After that, you divide that number by n (the number of weeks)

41/4=10.25 hours

Answer:

1/5

Step-by-step explanation:

it appears as those two distinct points on the graph are (-3,1) and (2,2)

so take the difference of the y-values and put it over the difference of the x-values to get a fraction to represent the slope

2-1 / 2-(-3) = 1/5

if you start from the point (-3,1) you must rise by one unit and then run five units to the right to get to (2,2)

Answer:

First option: (2,-6.5)

Step-by-step explanation:

The solution for this type of graph is basically where the two lines intersect. Remember that ordered pairs represent (x,y).

Hope this helps :)

Answer:

m=0,-8

Step-by-step explanation:

Rearrange this Absolute Value Equation

|m+4|+7 = 11

Another term is moved / added to the right hand side.

|m+4| = 4  STEP 2:

Clear the Absolute Value Bars

The Absolute Value term is |m+4|

For the Negative case we'll use -(m+4)

For the Positive case we'll use (m+4)

STEP3:Solve the Negative Case

     -(m+4) = 4

Multiply

     -m-4 = 4

Rearrange and Add up

     -m = 8   Multiply both sides by (-1)

     m = -8

    Which is the solution for the Negative Case

STEP4:Solve the Positive Case

     (m+4) = 4

Rearrange and Add up

     m = 0

Which is the solution for the Positive Case

STEP5:

Wrap up the solution

m=-8

m=0

Solutions on the Number Line

 Two solutions were found :

m=0,M=-8

Answer:

It depends

Step-by-step explanation:

It depends on how many problems are in the test. If the test has a standard amount of ten questions, you can only miss one question if you want to get a solid 90%. If the test has twenty questions, you can miss two to get that 90%.

If you're going for an 80% (or B), you can miss two on a ten-question test and four on a twenty-question test.

Again, it all depends on the number of questions and what percentage you want to get on the test.

Answer:

y=1/2x

Step-by-step explanation:

Its a positive slope so you go up 2 then right 4

Answer:

slope = [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0,  0) and (x₂, y₂ ) = (6, 3) ← 2 points on the line
