What is the equation of the line that passes through the point (8,-4) and has a slope of 3?
Answers
the equation is
Y=Mx+b
Plug it in as
-4=3(8)+b
-4=24+b
Then subtract 24
B=-28
So
The answer is
Y=3x-28
(8, -4) 8 is x1 and -4 is y1
so y- (-4) = 3 (x -8)
make 4 a positive then y + 4 = 3x - 24
subtract 4 from 24 then y=3x-20

Line segment AB has a length of 3 units. It is translated 2 units to the right on a coordinate plane to obtain line segment A prime B prime. What is the length of A prime B prime? (5 points)
1 unit
2 units
3 units
5 units
Answers
Answer:
The correct option is C.
Step-by-step explanation:
It is given that line segment AB has a length of 3 units. It is translated 2 units to the right on a coordinate plane to obtain line segment A'B'.
Translation is a rigid transformation. It means the shape and size of preimage and image are same. In other words we can say that the preimage and image are congruent.
Corresponding sides of congruent figures are congruent.
The length of A'B' is 3 units. Therefore the correct option is C.

-8(1+4x)+7x=-25-8x
Answers
Answer:
x = 1
Step-by-step explanation:
-8(1+4x)+7x=-25-8x (Given)
-8 + -32x + 7x = -25 - 8x (Distribute)\
-8 + -25x = -25 - 8x (Combine like terms)
-17x = -17 (Move variables(x) to the left and constants to the right)
x = 1 (Divide) (the answer is positive because when you divide a negative number by a negative number it turns positive)

Whenever the earth, moon and sun are aligned, the gravitational pull of the moon is augmented by the gravitational pull of the sun, causing larger than average tidal ranges — meaning especially high high tides and very low low tides. These extreme tides are called “spring tides.”

Answers
Answer:
(22,0)
Step-by-step explanation:
1. Select any two points given and find their slope (rise/run)
(-38, 40) and (-23, 30)
slope = [tex]\frac{40-30}{-38-(-23)}[/tex] = - 2/3
2. Use the slope and one of the points to create an equation of the line in the format y = mx + b, where m = slope and b = y-intercept.
y = mx + b ⇒ 40 = -2/3 (-38) + b
3. Solve for b
40 = -2/3 (-38) + b
40 = 76/3 + b
40 - 76/3 = b
b = 44/3
4. To find the x-intercept, set y = 0, and solve.
y = -2/3 x + 44/3
0 = -2/3 x + 44/3
2/3 x = 44/3
x = 22

PLEASE HELP The ratio of athletes in the two teams is 3:2. After 12 athletes move from first team to second, the ratio is 5:4. Find the number of athletes on each team originally.
Answers
Answer:
You can use the method of substitution and elimination.
Team A : Team B
3x : 2x
-12 +12
5y : 4y
3x-12=5y ---> (1)
2x+12=4y ---> (2)
12x-48=20y
10x+60=20y
12x-48=10x+60
12x-10x=48+60
= 108
2x=108
x=54
Original number of athletes on Team A = 3(54)
= 162
Original number of athletes on Team B = 2(54)
= 108
2,4,6,8,10,12= 6
So it is 4 and 6
