Answer:

-21

28

Step-by-step explanation:

1) if r = -4

Substitute r = -4 in 3r - 9

= 3 * (-4) - 9

= -12 - 9

= -21

2) ( 4 / 7 ) * x = 16

 4 * x = 16 * 7

 x = 4 * 7

 x = 28

Answer:

y = 6x + 23

Step-by-step explanation:

Flip 6x + 23 = 1y into 1y = 6x + 23

Also, 1y is the same as just saying y.

Answer:

$20.55

Explanation:

The total amount spent on apples is $20.5425.

Given that, Kathy is baking 3 apple pies. Each pie requires 2 3/4 pounds of apples. Apples cost $2.49 a pound.

We need to find out how much will Kathy spend on apples.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the amount spent on apples be x.

Now, 2 3/4=11/4

The total number of apples required to make 3 apple pies=3 × 11/4

=33/4 pounds

Apples cost $2.49 a pound.

So, the amount spent on apples=x=33/4 × 2.49

=$20.5425

Therefore, the total amount spent on apples is $20.5425.

Answer:

Nelson will be 17, and his father will be 45.

Step-by-step explanation:

So let's say 9 years went by. N= Nelson, F= Father

N 8+9 = 17

F 36+9 = 45

45 + 17 = 62.

BOOOOOOM!!!!

Answer:

Nelson: 17, Father: 45

Step-by-step explanation:

8 + 36 = 44          13 + 41 = 54

9 + 37 = 46          14 + 42 = 56

10 + 38 = 48         15 + 43 = 58

11 + 39 = 50         16 + 44 = 60

12 + 40 = 52         17 + 45 = 62

Answer:

Answer:c

Step-by-step explanation:

Linnea’s company’s revenue in 2017 as a percent of its revenue in 2016 is; 1.44%.

Now, we are told that her revenue in 2017 is 36/25 of her revenue in 2016.

To express this revenue as a percentage, we will multiply 36/25 by 100%.

⇒ 36/25 × 100%.

⇒ 1.44%

Thus, in conclusion Linnea’s company’s revenue in 2017 as a percent of its revenue in 2016 is 1.44%.

Answer:

1 is parallel to 3. 1 is perpendicular to 2. 2 is perpendicular to 3.

Step-by-step explanation:

The slope of line 1 is 5/3. This is because it is the m term from the equation y=mx+b.

The slope of line 2 is -3/5. You would have to solve the equation in the following format.

[tex]6x+10y-6x=-4-6x[/tex]

[tex]\frac{10y}{10}=\frac{-4-6x}{10}[/tex]

Which simplifies to y=-2/5 - 3/5x, making -3/5 the slope.

The slope of line 3 is 5/3, which can be found by dividing both sides of the equation by 3.

Parallel lines have exactly the same slope. So lines 1 and 3 are parallel.

Perpendicular lines have opposite reciprocal slopes. So lines 1 and 2, and 2 and 3 are both perpendicular.

Answer:

Step-by-step explanation:

y = mx + b

The line y = 3 is a horizontal line with slope zero

y = 0x + 3

All parallel lines will also have a slope zero

a parallel line passing through (-2, 7) will have the equation

y = 0x + 7

y = 7

Answer:

(x-5)/(x+1) and x cannot equal -1 because the denominator can't be zero.

Step-by-step explanation:

Factor the numerator:

(x+9)(x-5)

Factor the denominator:

(x+1)(x+9)

So you have

(x+9)(x-5)/(x+1)(x+9); see that you can cross out the (x+9) in both the numerator and denominator?

You're left with (x-5)/(x+1)

The only number that is restricted is -1, because that would make the denominator zero, which is a no no

Answer:

Step-by-step explanation:

To avoid ambiguity please write the given expression as  

                                                                 x² + 4x - 45

x² + 4x - 45/(x^2+10x+9) or (better) as ---------------------

                                                                   x^2+10x+9

Notice that both numerator and denominator have the factor x + 9:

 (x + 9)(x - 5)

---------------------

 (x + 9)(x + 1)

This allows us to cancel out the (x + 9) factor, resulting in:

x - 5

------- ONLY for x ≠ -1 and x = -9

x + 1

We must exclude these two x-values because otherwise the denominator would be zero, which is not allowed.

Step-by-step explanation:

Answer:

Slope intercept form: y = -x + 5

Point slope form: y - 4 = -1 (x - 1)

Step-by-step explanation:

First we need to find slope by using this formula⤵⤵⤵

[tex] \frac{y _{2} - y _{1} }{x _{2} - x _{1} } [/tex]

(Sorry if it's a bit small btw)

-1 - 4 = -5

6 - 1 = 5

Simplify -5/5 by dividing, and your slope is -1.

Now we plug in one of the points and the slope into the point slope formula⤵⤵⤵

[tex]y - y _{1} = m(x - x _{1})[/tex]

We'll use point (1,4) for this:

y - 4 = -1 (x - 1)

To solve this, start by distributing the -1 among everything inside the parenthesis to get

y - 4 = -x + 1. Next, add 4 on both sides to get

y = - x + 5.

Hope this helps you :)
