What is the slope of the line that passes through the points (4,8) and (-2,1) ?
Answers
Answer:
f(x) = 7/6
Step-by-step explanation:
First off, hello! This is my explanation to the provided answer,
You can use the slope formula, (or simply graph the points), y2 - y2 / x2 - x1.
This would give you: 1 - 8 / -2 - 4, meaning that you would get the answer: 7/6 as the slope.

Road Sign
The U.S. Department of Transportation determines the sizes of the trafic control signs that you see along the roadways. The square Pennsylvania state route sign at the right has an area of 1296 square inches. Find the side length of the sign.
(I need an answer and how to solve it please<3)
Answers
Answer:
A = S square (s^2)
we know that A = 1296 square inches, then,
[tex]\sqrt{1296} = \sqrt{s^{2}} \\[/tex] we square both sides and cancel out the square on the right side. We get:
36 = s
The length of the sign is 36 inches.

Answers
Answer:

9500 / 7 = 1357.14286 one part
1357.14286 x 3 = 4071.42858 = 4071 males
1357.14286 x 10 = 13571.42 is the same as

Answer:
68.50 in
Step-by-step explanation:
first we are given the width and the length for the rectangle and so we know that 4 × 5x + 7 = 128
so we would now solve for x:
4 × 5x + 7 = 128
= 4 × 5x = 121
= 20x = 121
= x = 6.05
now we can plug in 6.05 for x and find the perimeter:
5(6.05) + 4 = 34.25
5(6.05) + 4 = 34.25
34.25 + 34.25 = 68.50

Find the unknown sizes of angles in the following figure (I need step by step explanation and ill give brainliest):
Answers
Answer:
∠p, ∠q, and ∠r are all 40°
Step-by-step explanation:
ARQ is a triangle so the sum of the interior angles must equal 180°
48 + 52 = 100
180 - 100 = 80°
This means that the last angle, 2p = 80°
If 2p = 80, then ∠p = 40° (divide by 2)
PQR is also a triangle which means PR is a straight line
The angle next to 2p is going to be 100, because 2p was 80 and angles on a straight line add to 180° (180 - 80 = 100)
∠r = ∠p because they are alternate angles (in the sideways Z shape), 40°
∠q can be found by doing:
180 - (∠PAQ + ∠r)
= 180 - (100 + 40)
= 180 - 140
= 40

What is the slope of the line that passes through the points (10, 5) and (9,5)? Write your answer in simplest form.
Answers
Answer:
Slope = 0
Step-by-step explanation:
Equation: y = 5
Since the graph would show a horizontal line (passing through 5) the slope would be zero
Write an equation perpendicular to y = −1/5x + 9 that passes through the point (-2, -2) in slope intercept form. (y = mx + b)
What is the perpendicular slope?
Answers
Answer:
y = 5x + 8
m = 5
Step-by-step explanation:
ok so perpendicular means negative reciprocal of the slope so the original slope of the line is -1/5x so the negative reciprocal is 5 (5/1 and the negative undos the negative so it's positive) so now we will use the point (-2, -2) and plug that into the slope intercept form (y = mx+b)
so -2 = 5(-2) + b
5 • -2 = -10 and u add that to the other side so b = 8 so the answer is y = 5x + 8! hope this helps!

A population in a town has 2500 people in the first month of its development. Every month after that, the population constantly increases 1.25 times from the previous month. What will the population of the town be in the 4th month?
A.) About 4883 people
B.) About 6104 people
C.) 12500 people
D.) 9375 people
Answers
Answer:
6104 people.
Step-by-step explanation:
1.25 means it will multiply by 1 and a fourth
2500*1.25 =3125 the first month
3125*1.25=3906.25 the second.
3906.25*1.25=4882.8125 the third
4882.8125*1.25=6103.515625
round that up and you have 6104 people.

Joe’s age is three times Aaron’s age and Aaron is six years older than Christina. If the sum of their ages is 149, what is Christina’s age? Joe’s age? Aaron’s age?
Answers
Answer
If Christina's age is = x
Aaron's age is = x + 6
Jeo's age = 3(x + 6 )
So, the sum of their ages can be write as,
[tex]x + x + 6 + 3(x + 6) \\ x + x + 6 + 3x + 18 \\ 5x + 24[/tex]
Also, they have given that the sum of their ages is 149
Therefore we can write a equation as,
[tex]5x + 24 = 149[/tex]
Now let's solve this and find the age of Christina
[tex]5x + 24 = 149 \\ 5x = 149 - 24 \\ 5x =12 5 \\ \frac{5x}{5} = \frac{125}{5} \\ x = 25[/tex]
Aaron's age is
[tex] x+ 6 \\ 25 + 6 \\ = 31[/tex]
Joe's age is
[tex]3(x + 6) \\ 3(25 + 6) \\ 3 \times 31 \\ = 93[/tex]

y = -5/7(x) - 3/7
Step-by-step explanation:
1. We're already given the value of m in y = mx + b: -5/7. So, our equation looks like this so far: y = -5/7(x) + b.
2. To solve for b, the y-intercept, we use this formula: [tex]b = y_1 - m * x_1[/tex]
[tex]b = -4 - (-\frac{5}{7}) * (5)[/tex] [tex]b = -\frac{3}{7}[/tex]3. Now that we know the values of m and b, the equation looks like this: [tex]y = -\frac{5}{7}x -\frac{3}{7}[/tex].
Therefore, the answer is [tex]y = -\frac{5}{7}x -\frac{3}{7}[/tex].
