If y varies directly with x with a constant of proportionality of –2, what is y when x is 8? What is x when y is –20?
9514 1404 393
Answer:
y = -16x = 10Step-by-step explanation:
The direct proportion equation is ...
y = kx
where k is the constant of proportionality. Here, you're told k=-2, so the equation is ...
y = -2x
For x=8, the value of y is ...
y = -2(8) = -16 . . . . . do the multiplication
For y = -20, the value of x is ...
-20 = -2x
10 = x . . . . . . . . . divide both sides by -2
Answer:
-16 & 40
Step-by-step explanation:
When x = 8
y = -2 × 8
y = -16
When y = -20
x = -2 × -20
x = 40
What is the solution to the equation -5x + 10 = -13x
a) No solution
b) x=0
c) x=1
d) x=-1.25
Answer:
-1.25 =x
Step-by-step explanation:
-5x + 10 = -13x
Add 5x to each side
-5x + 10+5x = -13x+5x
10 = -8x
Divide by -8
10/ -8 = -8x/-8
-5/4 =x
-1.25 =x

1. Find the coordinates of the midpoint of AB for A(5, 12) and B(-4, 8).
2. Find the coordinates of G if P (-5,10) is the midpoint of EG and E has coordinates (-8,6).
1) The midpoint of AB for A(5, 12) and B(-4, 8) is (1/2, 10)
2) The coordinate of G will be at (-2, -20) if P (-5,10) is the midpoint of EG and E has coordinates (-8,6).
The midpoint of a line is the point that divides such a line into two equal parts.
The formula for calculating the midpoint of a line is expressed as:
[tex]M(X, Y) =(\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )[/tex]
1) Given the coordinates A(5, 12) and B(-4, 8).
X = (5+(-4))/2
X = (5-4)/2
X = 1/2
Get the coordinate Y
Y = (12+8)/2
Y = 20/2
Y = 10
Hence the coordinate of the midpoint of AB for A(5, 12) and B(-4, 8) is
(1/2, 10)
The formula for calculating the midpoint of a line is expressed as:
[tex]M(X, Y) =(\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )[/tex]
1) Given the midpoint P (-5, 10) and the coordinate (-8, 6)
Get the X coordinate of G
X = (x1+x2)/2
-5 = (x1-8)/2
-10 = x1 - 8
x1 = -10 + 8
x1 = -2
Get the Y coordinate of G
Y = (y1+y2)/2
10 = (y1+8)/2
20 = y1+8
y1 = 20-8
y1 = 12
Hence the coordinate of G will be at (-2, -20)

What is the solution for x in the equation?
-x+3/7=2x-27/5
A. x=-4/3
B. x=-3/4
C. x=4/3
D. x=3/4
Answer:
C
Step-by-step explanation:
-x+3/7=2x-27/5
Just bring all the x together, ad all the numbers together
-x - 3x = - 3/7 - 27/5
-4x = - 15/ 35 - 189/35
-4x = - 204 /35
4x = 204/35
x = 204 / 140
x = 1.457

(A) S + 2
(B) S-2
(C) S-1
(D) S +4
Answer:
B
Step-by-step explanation:
B because it says Valerie is 4 seconds faster than Peter so that should be S-4 but they tell you to find the average which is S-2 so that's your answer.
Hope I got this correct, I haven't done average in a long time.

Dilation by a scale factor of 4 and a reflection over the x-axis
Answer:
(-12, -20).
Step-by-step explanation:
A dilation of factor 4 moves (-3, 5) to (-3*4, 5*4) = the point (-12, 20).
A reflection over the x-axis is (x, y) ------> ( x, -y).
So ( -12, 20) goes to (-12, -20).
Solve each equation. Be sure to check for extraneous solution -7= |a-3|/-2
Answer:
a = -11, 17.
Step-by-step explanation:
-7 = |a-3| / -2
Multiply both sides by -2:
|a - 3| = 14
So a - 3 = 14
Giving a = 17
or
a - 3 =- -14
giving a = -11.
Checking these values:
-7 = |17-3| / -2 = 14/-2 = -7
- so a = 17 is a solution.
-7 = |-11-3| / -2 = 14/-2 = -7
so a = -11 is also a solution.
5-2x=-4x+9
Answer step by step
Answer:
x = 2
Step-by-step explanation:
5-2x = -4x+9
5+(-2x+4x) = (-4x+4x)+9 [Add 4x to each side to get ride of 4x on the right]
5+2x = 9
(5-5)+2x = (9-5) [subtract 5 from both sides to get rid of 5 on the left]
2x = 4
2x/2 = 4/2 [Divide each side by 2 to get x alone]
x=2
The solution to the equation 5 - 2x = -4x + 9 is x = 2.
Here, we have,
To solve the equation 5 - 2x = -4x + 9 step by step, we will combine like terms and isolate the variable x.
Here's how:
Start by simplifying both sides of the equation by combining like terms:
5 - 2x = -4x + 9
The left side has no like terms to combine, so we move to the right side:
-2x + 4x = 9 - 5
Simplifying further:
2x = 4
Now, we want to isolate the variable x.
To do that, we need to get rid of the coefficient 2 that is multiplied by x.
We can achieve this by dividing both sides of the equation by 2:
(2x)/2 = 4/2
Simplifying further:
x = 2
We have found the solution for the variable x.
Therefore, the solution to the equation 5 - 2x = -4x + 9 is x = 2.

find the nth term of 14 23 32 41
Answer:
5+9n
Step-by-step explanation:
Here, we notice that the series is in A.P. (Arithmetic Progression).
Therefore, first term a = 14
common difference d = 23 - 14 = 9
Therefore the nth term will be = a + [n -1] d
putting the values, we get
nth term = 14 + 9×[n-1]
= 14 + 9n - 9
= 5 + 9n
