20 pts and brainliest. please help me on this
Answer:
The equation of the line is 4y = -x + 19
Step-by-step explanation:
Firstly, we need to get the slope of the line;
Since it is through two points; we have the slope as;
y2-y1/x2-x1 = (5-3)/(-1-7) = 2/-8 = -1/4
Mathematically, we can write the equation of a straight line line as;
y = mx + c
So we have;
y = -1/4x + c
y = -x/4 + c
To complete the equation, we need the value of c.
we can choose any of the points and insert the x and y value
Thus;
3 = -7/4 + c
c = 3 + 7/4
c = 19/4
So our equation becomes;
y = -x/4 + 19/4
Multiply through by 4
4y = -x + 19
Answer:
y-3= -1/4 x (x-7)
Step-by-step explanation:
Find the slope of the line between
( 7 , 3 ) (7,3) and ( − 1 , 5 ) (-1,5) using m = y 2 − y 1 x 2 − x 1
m=y2-y1x2-x1 , which is the change of y/ y over the change of x/ x .

if a van traveled 200 miles in 5hours how far could the van go in 8hours
Answer:
320 mph
Step-by-step explanation:
200/5=40
40x8=320
A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. The van travelled 320 miles in 8 hours.
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given,
if a van traveled 200 miles in 5 hours
We need to find how long it travels in 8 hours.
Let x be the distance to travel in eight hours.
Let us make a equation
200/5=x/8
Apply cross multiplication
1600=5x
Divide both sides by 5
1600/5=x
320=x
Hence the van travelled 320 miles in 8 hours.

The first set:

Represents a function.
Which set of ordered pairs represents a function?
A function is a relationship that maps elements from a set (inputs) into elements from another set (output). Such that each input can be mapped into only one output.
Then, for example, the second set:
{(0, 1), (1, 2), (1, 3), (2, 5)}
Is not a function, because the input x = 1 is being mapped into y = 2 and y = 3.
The only case where the inputs are not repeated is on the first set:
" {(0, 1), (1, 2), (2, 3), (3, 3)}"
Where no input is repeated, so this is a function.

Given; D is the Midpoint of CE / Prove DE =1/2CE
Answer:
Check explanation
Step-by-step explanation:
Here, we want to make a prove;
Mathematically , since D is the midpoint of CE
Then;
CE = CD + DE
Also, since D splits the line segment into two equal parts as the midpoint, then CD must be equal to DE
I.e CD = DE
Hence, we can express CE as follows;
CE = DE + DE
CE = 2 DE
Divide both sides by 2
CE/2 = DE
Hence; DE = 1/2 CE

-36x+36=180
-36x=144
X=-4
Then put -4 in -16(-4) + 13 = 77
Answer is 77
The angle LMP will be 75.22° and the angle NMP will be 104.77°.
What is an angle?An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.
In another word, the angle is the measurement of the angular distance for example for linear motion we have a meter inch but for angular rotation, we don't have the measurement so the angle is useful to measure the angular rotation.
∠LMN = ∠ LMP + ∠NMP
Since ∠LMN = 180°
So,
∠ LMP + ∠NMP = 180
-16x + 13 - 20x + 23 = 180
-36x + 40 = 180
36x = -140
x = -3.88
So,
∠ LMP = -16(-3.88) + 13 = 75.22°
So,
∠NMP = 180 - 75.22 = 104.77°
Hence "The angle LMP will be 75.22° and the angle NMP will be 104.77°".

Two car rental companies charge an initial rental fee plus a fee per day. The table shows the total costs of renting a car for x days from
Discount Car Rentals. The total costy (in dollars) of renting a car for x days from Pay Less Rentals is represented by the equation
y=25x + 170. Which rental company charges less per day? How many days must you rent a car for the total costs to be the same?
Answer:
Step-by-step explanation:
Two car rental companies charge an initial rental fee and a fee per day.
Total cost for the company A is given by the equation,
y = 25x + 170
Car A charges $25 per day. [Slope of the line]
Another car rental company B charges as per table attached.
Per day car rental for the company B = [tex]\frac{270-180}{4-2}[/tex]
= [tex]\frac{90}{2}[/tex]
= $45 per day
Therefore, per day rental charged by company A is less.
Let the equation for the car rental by company A is,
y = mx + b
where m = per day rental charged by company A = $21.5
y = 45x + b
One point (2, 180) from the table lies on the equation.
Therefore, 180 = 45(2) + b
b = 180 - 90
b = 90
So the equation will be,
y = 45x + 90
If both the company charge the same after x day of rental,
45x + 90 = 25x + 170
45x - 25x = 170 - 90
20x = 80
x = 4
After 4 days car rentals for both the companies will be same.

Step-by-step explanation:
ANSWER: Degrees
explanation:
The difference between the linear and nonlinear functions are their degrees. For linear functions, the highest order is only 1 while more than for those nonlinear functions. If these are presented in graphs, linear functions would generate straight lines while parabola or other curved lines will be generated for nonlinear functions.

Explicación paso a paso:
Dados los datos:
Datos de jonrones durante 11 años:

[(56 + 62 + 49 + 65 + 58 + 52 + 68 + 72 + 25 + 64 x) / 11] = 60
[(571 + x) / 11] = 60

What is the reciprocal of 2 and 9 over 10?
Answer:
Part A: [tex]\frac{1}{2}[/tex]
Part B: [tex]\frac{10}{9}[/tex]
Step-by-step explanation:
Part A: What is the reciprocal of 2.
2 is just [tex]\frac{2}{1}[/tex] in fraction terms. To find the reciprocal, you just have to flip it over. That would get to [tex]\frac{1}{2}[/tex]. Therefore, the reciprocal is [tex]\frac{1}{2}[/tex].
Part B: What is the reciprocal of 9 over 10?
9 over 10 in numerical terms is just [tex]\frac{9}{10}[/tex]. o find the reciprocal, you just have to flip it over. That would get to [tex]\frac{10}{9}[/tex]. Therefore, the reciprocal is [tex]\frac{10}{9}[/tex].

Then we simplify both sides of the equation, so we get 11-x=-1-3x. When we separate the numbers and variables, we get -12=-2x. -12/2 = -6.

Use the triangle sum conjecture to determine each lettered angle measure.
Pls help!
Answer:
a = 69
b = 47
c = 116
d = 93
e = 86
See ALL MATH below!
Step-by-step explanation: (PLEASE READ!!!) ;3
remember that the sum of all the angles in a triangle will always add up to be 180.
All angles in a quadrilateral will be 360.
Pentagon, 540, and the center shape in your problem, hexagon, 720°
It's easier to think about this problem when you look at the two separate triangles, and not the small individual shapes. SO...
one of them, the one that points down, only has a single missing angle (a)
we can find that by doing this:
40 + 71 = 111
180 - 111 = 69
so a = 69
to find B, it's actually more simple. b+133, the angle next to it, will add up to 180, because it's a straight line. so...
180-133 = 47, so B = 47
now that you have a and b, we can find c by using the same method we used to find b, but first we need the angle next to it, so we use the method to find a!
180 - (a + b) = needed angle
180 - needed angle = c
69 + 47 = 116
180-116 = 64
now we have 64. we will subtract that from 180 to get c!
180- 64 = 116
the easiest way to find d is to find the other angle in that small triangle to the bottom right, so we'll subtract 140 from 180, which is 40. 47 + 40 = 87
180 - 87 = 93
d = 93!
finally for e, I'm going to do my work below, I'll have to find many other angles to get e, so maaaaybe you'll be able to follow along.
71+40=111, 180 - 111 = 69
180 - 69 = 111
111 is the angle to the left of the given 140.
NOW we can focus on that little triangle to the left, after we get the bottom left most angle, we can add that with 47, subtract it from 180, and we'll have e!!!
180-111 = 69 (bottom right angle of little triangle)
180-116 (c) = 64 (top angle)
69 + 64 = 133
180 - 133 = 47!!
Now we have two angles of the large triangle that points up. using them, we can find the last one, E.
47 + 47 = 94
180 - 94 = e
