Answer: 7/20 of the laundry still needs to be washed

Step-by-step explanation:

1. Find the gcf (greatest common factor) of 2/5 and 1/4, the greatest common factor of both 5, and 4, is 20.

2. Now, we have to use the 20, and rewrite the numbers. The 2/5 can be written as 8/20, and the 1/4 can be written as 5/20.

3. if Ms. Jones has washed 8/20 of the laundry, and her son has washed 5/20 of it, together they have washed 13/20 of it.

4. 20-13=7, so 7/20 of the laundry still needs to be washed.

The two lines y= 6x+15 and y= mx+4 intersect at x= -2. What is the y-coordinate of their intersection point
taurus [48]

Answer:

The y-coordinate of their intersection point is 3

That is y=3

Step-by-step explanation:

Given two lines are y=6x+15 and y=mx+4

Given that the two lines intersect at x=-2

To find the y coordinate of their intersection point :

Equating the two lines

6x+15=mx+4

6x+15-mx-4=0

6x-mx+11=0

(6-m)x+11=0

At x=-2  (6-m)x+11=0

(6-m)(-2)+11=0

(6-m)(-2)=-11

6-m=\frac{11}{2}

-m=\frac{11}{2}-6

-m=\frac{11-12}{2}

-m=\frac{-1}{2}

m=\frac{1}{2}

Substitute the value m=\frac{1}{2} in y=mx+4 we get

y=\frac{1}{2}x+4

At x=-2 y=\frac{1}{2}(-2)+4

=-1+4

=3

Therefore y=3

Therefore the y-coordinate of their intersection point is 3
