Find the equation of the line parallel to y=2x+6 passing through (4,5)
ozzi

Answer:

y=2x-3

when two lines are parallel, they have the same slope.

in the formula y=mx+b, m=slope of the line

we know 2 will be the slope for the line passing through (4,5)

next plug in (4,5) into the formula with 2 as the slope

4=x 5=y

next 5=2(4)+b

and you end up with

y=2x-3 when you simplify

Graph the following quadratic function using transformations​
lorasvet [3.4K]
You start with the basic y=x^2.
That’s the parabola with a vertex at (0,0), opening up, etc.

The transformation aspect is the “+7” portion. This “+7” shifts the entire graph of y=x^2 up by 7 units.
The vertex is now (0,7), it still opens up, etc.

It’s kind of a silly question for your teacher to ask when the graph given only goes up to 6.

sasha drove from her house to the grocery store in 20 minutes. her return trip took 15 minutes. if the store is 7 miles from her
otez555 [7]
<span>Sasha drove from her house to the grocery store in 20 minutes.
Her return trip took 15 minutes. IF the store is 7 miles from here house.
Find Sasha’s average speed for her round trip in miles per hour.
=> 20 minutes + 15 minutes = 35 minutes
=> 35 minutes is the time of her travel.
=> 7 miles is the distance.
We need to solve for the average speed.
Formula = Speed = distance / time
=> 7 / 35
=> 0.2
thus, her speed is 0.2 miles per minute (.2miles/min)
