Midpoint problem. Given two endpoints P1 (8, -4) and P2 (-3, 9), find the midpoint. Enter just the x-coordinate in this problem.
Given parameters:
The coordinates are:
P1 (8, -4) and P2 (-3, 9)
Unknown:
The midpoint of the endpoints = ?
Solution:
x₁ = 8
y₁ = -4
x₂ = -3
y₂ = 9
midpoints; x[tex]_{m}[/tex] , y[tex]_{m}[/tex] = [tex]\frac{x_{1} + x_{2} }{2} ,[/tex] [tex]\frac{y_{1} + y_{2} }{2}[/tex]
= [tex]\frac{8 +(-3)}{2}[/tex] , [tex]\frac{-4 + 9}{2}[/tex]
= [tex]\frac{5}{2}[/tex] , [tex]\frac{5}{2}[/tex]
The coordinate of the x-axis is [tex]\frac{5}{2}[/tex]

Write the equation of the line that passes through (1, 3) and has a slope of 2 in point-slope form.
Answer:
y=2x+1
Step-by-step explanation:
The point-slope form is (y-y1)=m(x-x1), with x1 and y1 being the coordinates from ordered pair, and m being the slope. You can plug all of those values into the original equation:
(y-y1)=m(x-x1)
y-3=2(x-1)
y-3=2x-2
y=2x+1

Answer:
its linear (i know how to draw the graph but i cant show you here, just make umm an x axis and y axis from 1 to 30 ) (also i feel like theres another way to know if its linear but this is how i would do it!)
Step-by-step explanation:
to see if its linear ummm we first have to find the slope, the equation for the slope is
y2 - y1 / x2 - x1
lets use the points (2, 8) and (3, 12)
12 - 8/ 3 -2
4 / 1
4
y = 4x + b
now to find the y-intercept lets input a point we did not use yet
(5, 20)
20 = 4(5) + b
20 = 20 + b
b = 0
y = 4x
now we check if its linear with the points (6, 24) and (3.5, 14) sooo
24 = 4(6) ?
24 = 24
14 = 4(3.5) ?
14 = 14
so yes it is a linear graph

Answer:
25
Step-by-step explanation:
complementary angles is when their sum = 90 so
30 + 2x + 10 = 90
2x = 90 - 40
2x = 50
X = 25
Answer:
x = 25
Step-by-step explanation:
1. Due to the fact that Angle F and angle G are complementary, 2x + 10 + 30 = 90.
2. Solve this equation: 2x + 10 + 30 = 90
Add 10 and 30
2x + 10 + 30 = 90
2x + 40 = 90
3. Subtract 40 from 90
2x + 40 = 90
2x = 90 - 40
2x = 50
4. Divide 2 from 50
x = 50/2
x = 25

Mary has been hired as a receptionist. She is paid a flat rate of $150 each week and earns an additional
$12.50 for every hour that she works. If her goal is to make $575 in one week, how many hours must Mary
work?
Answer:
34
Step-by-step explanation:
$575-$150= $425
So $425 is how much she needs bc she already gets $150 each week so subtract it from the $575. then do
$425/$12.50=(hours)34) so she needs to work 34 hours this week to get 575$

Answer:

factor?
what is the area of y°
Answer: Below
Step-by-step explanation:
First, we start with x. We see the x is opposite of 30, so x is 30.
x + y + y = 180, since they lay on a straight angle.
180 - 30 = 150
since we still have 2 y's left:
2y = 150
y = 75

What is Logarithm?How many times must one "base" number be multiplied by itself in order to generate another specific number? The answer is found using a logarithm (or log).
For instance, how many times must a base of 10 be multiplied by itself to get 1,000? The answer is 3 (1,000 = 10 × 10 × 10).
Given that;
We have to use the property as;
aᵇ = x then
b = logₐx
So, we get;
log₁₂ 144 = a
12ᵃ = 144
12ᵃ = 12²
On comparing the base
= 2
Now, second is,
log₁₅ 1 = a
15ᵃ = 1
a = 0
Now, log₃ (1/81)
3ᵃ = 1/81
3ᵃ = 3⁻⁴
a = - 4
And, log 0.00001
= log (10)⁻⁵
= -5 log 10
= -5

Find the Area of the trapezoids
Hey there!
A = ½ (a + b) h,
a =8b = 16h =14⇒ A = ½(8+16)14
⇒ A = ½(24)14
⇒ A = (12)(14)
⇒ A = 168
Therefore, Area of trapezoid is 168 sq. un
Check the picture below.

Carlos was having a home built. The blueprints are shown below. The scale for the blueprints to the actual house is 2 inches to 7 feet.
Part A What is the actual width of the entire building
Part B What is the length of the entire building
The actual width of the entire building is 28 feet and the length of the entire building is 84 feet.
Given that, the scale for the blueprints to the actual house is 2 inches to 7 feet.
What is the scale factor?The scale factor is defined as the number or the conversion factor which is used to change the size of a figure without changing its shape. It is used to increase or decrease the size of an object. The scale factor can be calculated if the dimensions of the original figure and the dimensions of the dilated (increased or decreased) figure are known.
Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.
Now, width = 8 inches in feet is 4 × 7 =28 feet
Length = 14+10 =24 inches in feet is 12 × 7 = 84 feet
Therefore, the actual width of the entire building is 28 feet and the length of the entire building is 84 feet.
