HELP ME!!! I WILL MARK AS BRAINLY
Answer:
4
Step-by-step explanation:
We can see from the two marked points the coordinates are: (2, 8) and (4, 16)
That means the rise (vertical change) is 16 - 8 = 8 units. And the run (horizontal change) is (4 - 2) = 2 units.
Therefore slope = rise/run = 8/2 = 4.

George is 3 years older than the quotient of Joseph's age and 2. Letj represent joseph's age. Write an expression in the box
that would show George's age
Answer:
j/2+3
Step-by-step explanation:
Joseph's age is unknown, so we will use j. It says the quotient of Joseph's age (j) and 2, so it would be j/2, or j divided by 2.
Then it says that George is 3 years older, so that would be addition.
Therefore, it would be:
x/2+3

does anyone know what -23= 13w+2w+22 is plz help!
Answer:
w = -3
Step-by-step explanation:
-23 = 13w + 2w + 22
Combine like terms (add 13w and 2w and subtract 22 from both sides)
-45 = 15w
Divide both sides by 15
w = -3

the bearing of a plane from the airport is 65.
Calculate the bearing of the airport from the plane
Answer:
The bearing of the airport from the plane is 245°
Step-by-step explanation:
The bearing of a point from a location is given by the angle in degrees of rotation from the Northern direction of the location to the direction of the location of the point
The given bearing of the plane from the airport = 65°
Therefore, the direction of the plane from the Northern direction of the airport = 65°
From the Northern direction of the plane, the bearing of the airport = 245°
If a rectangular prism has a base area of 14 square centimeters and a height of eight centimeters, what is the volume?
Answer:
The volume is 112 cm³
Step-by-step explanation:
I think it's 112 because to find the volume of a rectangular prism you must multiply the length* width* height and 14 the base( base =legth*width) multiplied by 8 equals 112 cm³

x+2y=17
8x+3y=45
answer fast
Answer fast? What?
x + 2y = 17...Equation A
8x + 3y = 45...Equation B
Solve A for x.
x = 17 - 2y
Plug this into B to solve for y.
8(17 - 2y) + 3y = 45
136 - 16y + 3y = 45
136 - 13y = 45
-13y = 45 - 136
-13y = -91
y = -91/-13
y = 91/13
y = 7
To find y, plug x = 7 into either equation to find x.
I will use Equation A.
x + 2y = 17
x + 2(7) = 17
x + 14 = 17
x = 17 - 14
x = 3
Answer: x = 3, y = 7
The solution to the system of equations is (x = 3) and (y = 7).
To find the values of x and y that satisfy the given system of equations:
1. (x + 2y = 17)
2. (8x + 3y = 45)
We can use either the substitution method or the elimination method. Let's use the elimination method to solve this system
Step 1: Multiply both sides of the first equation by 3 to make the coefficients of y in both equations the same:
(3x + 6y = 51)
Step 2: Now, subtract the modified first equation (3x + 6y = 51) from the second equation (8x + 3y = 45):
(8x + 3y) - (3x + 6y) = 45 - 51)
Simplify:
(8x + 3y - 3x - 6y = -6)
Step 3: Combine like terms:
(5x - 3y = -6)
Step 4: Now, we have two equations:
1. (x + 2y = 17)
2. (5x - 3y = -6)
Step 5: Now, you can either use the substitution method or the elimination method again to find the values of x and y. Let's use the elimination method again to eliminate y: Multiply the first equation by 3 and the second equation by 2 to make the coefficients of y the same:
1. (3(x + 2y) = 3 times 17) => (3x + 6y = 51)
2. (2(5x - 3y) = 2 times -6) => (10x - 6y = -12)
Step 6: Now, add the modified first equation (3x + 6y = 51) to the modified second equation (10x - 6y = -12): (3x + 6y + 10x - 6y = 51 - 12)
Simplify: (13x = 39)
Step 7: Divide both sides by 13 to solve for x:
(x = frac{39}{13})
(x = 3)
Step 8: Now that we have the value of x, we can find the value of y by substituting it back into either of the original equations. Let's use the first equation:
(x + 2y = 17)
(3 + 2y = 17)
Step 9: Solve for y:
(2y = 17 - 3)
(2y = 14)
(y = frac {14}{2})
(y = 7)

What type of association is shown by the data in the scatter plot?
Answer Choices:
A. positive association
B. negative association
C. no association
D. trend association
=================================================
Explanation:
We can draw a straight line fairly close to all of the points. This line is known as the regression line, or line of best fit. Since this line has a negative slope, we consider the points to have negative association.
Put another way: as x goes up, y goes down, or vice versa. The two work opposite variables do opposite actions.
-----------------
Extra info:
Positive linear association would be when x and y go up together, or go down together. The variables go in the same direction together. The regression line would have positive slope.Points with no linear association would either be randomly scattered points, or perhaps another function type (eg: quadratic) would fit the points. The term "trend association" just seems to be something your teacher made up in order to possibly confuse students.PLSSS I NEED THIS QUICK AND WRITE IN SCIENTIFIC NOTATION

Given triangle PRS is congruent to triangle CFH, find the values of x, y, and z.
Answer:
x = 23
y = 7
z = 11
Step-by-step explanation:
Since ∆PRS ≅ ∆CFH, therefore,
m<R = m<F
13y - 1 = 90° (substitution)
Add 1 to both sides
13y - 1 + 1 = 90 + 1
13y = 91
Divide both sides by 13
13y/13 = 91/13
y = 7
Since ∆PRS ≅ ∆CFH, therefore,
PS = CH
2x - 7 = 39 (substitution)
Add 7 to both sides
2x - 7 + 7 = 39 + 7
2x = 46
Divide both sides by 2
2x/2 = 46/2
x = 23
Since ∆PRS ≅ ∆CFH, therefore,
m<S = m<H
Find m<S
m<S = 180 - (m<P + m<R) (sum of ∆)
m<S = 180 - (28 + (13y - 1)) (substitution)
Plug in the value of y
m<S = 180 - (28 + (13)(7) - 1))
m<S = 180 - (28 + 91 - 1)
m<S = 180 - 118
m<S = 62°
Therefore, since m<S = m<H,
62° = 6z - 4 (substitution)
Add 4 to both sides
62 + 4 = 6z - 4 + 4
66 = 6z
Divide both sides by 6
66/6 = 6z/6
11 = z
The values of x, y, and z are;
x = 23
x = 23y = 7
x = 23y = 7z = 11
We are told that triangle PRS is congruent to triangle CFH.
Since both triangles are congruent, by inspection we can see that;
m<R = m<F
m<F is a right angle = 90°. Thus;
13y - 1 = 90
13y = 90 + 1
13y = 91
y = 91/13
y = 7
Also by inspection;
PS = CH
2x - 7 = 39
2x = 39 + 7
2x = 46
x = 46/2
x = 23
Since m<R is 90°, then;
m<S = 180 - (90 + 28)
m<S = 62°
By inspection;
m<S = m<H
Thus;
6z - 4 = 62
6z = 66
z = 66/6
z = 11
