Answer:
y = 8/7x+3/7
Step-by-step explanation:
We can find the slope using the slope formula
m = ( y2-y1)/(x2-x1)
= ( 5 - -3)/( 4 - -3)
= ( 5+3)/ ( 4+3)
=8/7
The slope intercept form of the equation is y = mx+b
y = 8/7x+b
Substitute a point into the equation
5 = 8/7 *4 +b
5 = 32/7 +b
35/7 = 32/7 +b
Subtract 32/7 from each side
35/7 - 32/7 =b
3/7 =b
y = 8/7x+3/7
Answer:
y = 8/7x+3/7

how does increasing the mass affect the gravity of the planet? How do you know?
I’m rlly struggling on this question so I’ll give brainliest to the best answer and 50 points<3
Answer:
there are two factors to the strength of the gravitational force, mass and distance. if the mass between 2 objects is increased the gravitational force between the 2 objects is also increased.
Since the mass of a body is directly proportional to the graviational force so by increasing the mass the gravitational force also increases.
What is gravitational force?The gravitational force is a force that attracts any two objects with mass. We call the gravitational force attractive because it always tries to pull masses together, it never pushes them apart. In fact, every object, including you, is pulling on every other object in the entire universe.This is called Newton's Universal Law of Gravitation.
The formulas for the universal gravitational force is given by
[tex]F=\dfrac{Gm_1m_2}{r^2}[/tex]
Here G is the universal gravitational constant m1 and m2 are the masses of the two planets. r is the distance between the two bodies.
So from the formula, it is clear that the gravitational force between the two bodies is directly proportional to the masses of the planets.
So when the mass of the planets is high then the gravitational force will also be higher.

1.A cell phone is advertised for 25% off the list price of D dollars. Write an algabraic expression that represents the sale price of the phone?
2. A car travels for 10 hours at an average speed of s miles per hour, write an algabraic expression that represents the total distance traveled by a car.
Answer:
$0.75D ; 10s miles
Step-by-step explanation:
1)
Given that:
List price of phone = $D
Advertised price = 25% off the list price
Hence, sales price of phone :
(100% - 25%) × list price
Sales price = 75% × $D
Sales price = $0.75D
2)
Given that :
Time of travel = 10 hours
Speed of travel = s miles per hour
Total distance traveled = (speed of travel × time of travel)
Total distance traveled = (10 * s) miles

evaluate r(x) = -x -7 when x = -2, 0, and 5
Answer:
r(-2) = -5 , r(0) = -7 , r(5) = -12
Step-by-step explanation:
Plug in the numbers for x and then solve. : )
r(-2) = - (-2) - 7
r(-2) = 2 -7
r(-2) = -5
r(0)= -0 -7
r(0)=0-7
r(0) = -7
r(5) = -5 - 7
r(5) = -12
The values of r(x) for x = - 2, 0 and 5 are obtained by Substituting the values for x in the function, hence the values are :
r(-2) = -9r(0) = -7r(5) = -2When x = - 2
Substitute the value of x = - 2 into the function r(x) = - x - 7 r(-2) = - 2 - 7 = - 9When x = 0
Substitute the value of x = 0 into the function r(x) = - x - 7 r(-2) = 0 - 7 = - 7When x = 5
Substitute the value of x = 5 into the function r(x) = - x - 7 r(-2) = 5 - 7 = - 2Therefore, the required values are - 9, - 7 and - 2

Step-by-step explanation:
a) When the length of AC = 5 in. and CB = 3 in. we have;
The length of [tex]\overline {AB}[/tex] = AC + CB (segment addition postulate)
Therefore;
[tex]\overline{AB}[/tex] = 5 in. + 3 in. = 8 in.
b) When the length of AC = [tex]6\frac{1}{2}[/tex] in. and BC = [tex]3\frac{1}{2}[/tex] in. we have;
The length of [tex]\overline {AB}[/tex] = AC + CB (segment addition postulate)
Therefore;
[tex]\overline{AB}[/tex] = [tex]6\frac{1}{2}[/tex] in.+ [tex]3\frac{1}{2}[/tex] in. = 10 in.
c) When the length of AB = 10.2 in. and BC = 3.7 in. we have;
The length of [tex]\overline {AC}[/tex] = AB - BC (converse of the segment addition postulate)
Therefore;
[tex]\overline {AC}[/tex] = 10.2 in.+ 3.7 in. = 6.5 in.
d) When the length of AB = [tex]4\frac{3}{4}[/tex] in. and BC = [tex]3\frac{1}{4}[/tex] in. in. we have;
The length of [tex]\overline {BC}[/tex] = AB - AC (converse of the segment addition postulate)
Therefore;
[tex]\overline {BC}[/tex] = [tex]4\frac{3}{4}[/tex] in. - [tex]3\frac{1}{4}[/tex] in.= [tex]1\frac{1}{2}[/tex] in.

A. Write and solve an equation to find x, the number of meters Skyler must add to her personal best to tie the district record.
Enter your answer.
B. Look for Relationships Rewrite your equation as an inequality to represent the situation where Skyler breaks the district record. How is the value of x in the inequality related to the value of x in the equation?
Equations are expressions that have equal values, while inequalities are used to represent unequal expressions
The number of meters Skyler must add is 0.09The inequality that represents the scenario is [tex]x + 1.48>1.57[/tex]How to determine the number of metersFrom the question,
Skyler's personal best is 1.48 meters highThe high jump bar is 1.57 meters highThe number of meters (x) Skyler must add is represented using the following equation
[tex]x + 1.48 = 1.57[/tex]
Solve for x
[tex]x = 0.09[/tex]
The inequalityTo break the record, the number of meters added to his personal best must be greater than 1.57.
So, we have:
[tex]x + 1.48>1.57[/tex]

Answer:
-0.3125
Step-by-step explanation:
0.18(y-1)= 0.24(2y-3)
plz explain briefly and correctly plz answer only if u know
Answer: Y = 1.8
Step-by-step explanation:
So the parentheses that is next to the 0.18 is everything 0.18 is being multiplied by, it is the same as saying 0.18 x y and 0.18 x -1 and the same thing on the other side.
so your new equation would be
0.18y -0.18 = 0.48y - 0.72
You have a few options next, you want to get the y variable all by itself, so you should get rid of everything next to it, and you do that by doing the opposite of what it is to cross it out of one side and do it to the other side, for example
0.18y -0.18 = 0.48y -0.72
0.18y +0.18 = 0.48y -0.72 + 0.18
0.18y = 0.48y -0.54
now that you have y alone on one side, you may use the other y and subtract it from both sides.
0.18y - 0.48y = -0.54
-0.3y = -0.54
now to get y completely alone, divide it by -0.3 and -0.54
and you get the answer of Y = 1.8

M is the midpoint of RS and R has coordinates (2,5 M has coordinates (6,9) find the coordinates of S
here is the ans my friend
The midpoint of the line RS will be (4,7).
What is a midpoint?The midpoint of a line segment is known as the midpoint in geometry. It is the centroid of the segment and of the ends, and it is equally distant from both of them. It cuts the section in half.
The midpoint will be calculated by using the formula below:-
Midpoint = [ ( x₁ + x₂ ) / 2 , ( y₁ + y₂ ) / 2 ]
The given points are (2,5) and (6,9). The value of the midpoint will be calculated by using the formula above:-
Midpoint = [ ( x₁ + x₂ ) / 2 , ( y₁ + y₂ ) / 2 ]
Midpoint = [ ( 2 + 6 ) / 2 , ( 5 + 9 ) / 2 ]
Midpoint = [ ( 8 ) / 2 , ( 14 ) / 2 ]
Midpoint = [ 4 , 7 ]
