find the equation of a line parallel to the given line in passing through the given point
y=3;(-2,7)
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
After six biology tests, Ruben has a mean score of 75. What score does Ruben need on the next test to raise his average (mean) to 77?
Ruben's score on the next test to raise his average (mean) to 77 is 89.
What is the average?The average is the quotient of the total divided by the number of items involved.
The average is also known as the mean.
The mean is one of the values of central tendency. Other values of central tendency include the mode and the median.
The number of biology tests taken by Ruben so far = 6
The mean score of the six tests = 75
The total score so far in the six tests = 450 (6 x 75)
The expected average for seven tests = 77
The total score for the seven tests = 539 (77 x 7)
The expected score for the seventh test = 89 (539 - 450)
Thus, Ruben is expected to score 89 for his average score to be 77.

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
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.

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%.

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.
