Answer:
13
Step-by-step explanation:
input is X
and output is Y
if the input is 4, then we need to plug in x=4
we get
y=3*4 + 1 = 12+1=13
Answer:
13
Step-by-step explanation:
If you plug in 4 for x (the input) and do the math. 3x4 is 12 then 12+1 is 13

Nelson is 8 years old. His father is 36 years old. How old will Nelson and his father be when the sum of their ages is 62?
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

Kathy is baking 3 apple pies. Each pie requires 2 3/4 pounds apples. Apples cost $2.49 a pound. About how much will Kathy spend on apples?
Answer:
$20.55
Explanation:
1apple pie needs 2/3/4pounds of apple 1pound cost $2.492/3/4 = ?2/3/4 ×2.49 =$6.85 for one pieFor 3 pies , =$6.85×3 = $20.55The 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.
What is an equation?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:
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.

find the point slope asap plsssssss
Answer:
(5,-5)
Step-by-step explanation:
-1-4
------ = (5,-5)
(6-1)
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 :)

Simplify completely
x² + 4x - 45/x^2+10x+9
and find the restrictions on the variable.
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.

Substitute r = -4 in 3r - 9
= 3 * (-4) - 9

Linnea’s company’s revenue in 2017 is 36/25 of its revenue in 2016
What is Linnea’s company’s revenue in 2017 as a percent of its revenue in 2016
Linnea’s company’s revenue in 2017 as a percent of its revenue in 2016 is; 1.44%.
Let Linnea’s company’s revenue in 2016 be x.Now, we are told that her revenue in 2017 is 36/25 of her revenue in 2016.
This means the revenue in 2017 = (36/25)xTo 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%.
