Answer:

(2,4)

Step-by-step explanation:

that would be the answer because when you reflect it over the Y axis you are making the y turn into a + or - depending on what it already is if y=-4 when you reflect it over the y it would be y=4

Write the equation of the line that has a slope of m=3 and passes through (4 , 2)

mina [271]

Answer:

y=3x-10

Step-by-step explanation:

For this, you would use the point slope formula, which is (y-y1)=m(x-x1). x1 and y1 are the coordinates from the ordered pair.

(y-y1)=m(x-x1)

(y-2)=3(x-4)

y-2=3x-12

y=3x-10

To check, you can plug the coordinates into the equation.

y=3x-10

(2)=3(4)-10

2=12-10

2=2

The graph shows the amount of water that remains in a barrel after it begins to leak. The variable x represents the number of da

vivado [14]

A = ( 15 , 15 )

B = ( 6 , 33 )

$slope = \frac{y(b) - y(a)}{x(b) - x(a)} \\$

$slope = \frac{33 - 15}{ 6 - 15} \\$

$slope = \frac{18}{ - 9} \\$

$slope = - 2$

Thanks for watching buddy good luck.

A motorcycle travels north along

Sindrei [870]

Answer:

42 mph

Step-by-step explanation:

From 2 p.m. to 6 p.m. 4 hours passed, so the truck and the motorcycle were on the road for 4 hours until they met.

Motorcycle in 4 hours at a constant speed of 45 mph travelled

$45\cdot 4=180\ miles$

The distance between the motorcycle and the truck is 348 miles, so the truck travelled

$348 -180=168\ miles$

If x mph is truck's speed, then

$168=4\cdot x\\ \\x=\dfrac{168}{4}=42\ mph$
