Does (8,32) lie on the line y=4x

Answers

Answer:

Yes, (8,32) lie on the line y=4x

Solution:

Given equation of line

y=4x ---- eqn 1

Any point lie on the line if that point satisfies the equation of line.

So from question given point is (8, 32) that is x=8 and y=32

On substituting x=8 and y=32 in equation (1)

32 = 4(8)

32 = 32

Since Left hand side is equal right hand side, the points (8,32) satisfies the equation of line y = 4x

Hence (8,32) lie on the line y=4x

Answer: yes it does

Step-by-step explanation:

Ordered pair: (8,32)

y=4x

32= 4(8)

32 = 32

Jessica is making 2 loaves of banana bread. She needs 3/4 cup of sugar for each loaf. Her measuring cup can only hold 1/4 cup of sugar. How many times will Jessica need to fill the measuring cup in order to get enough sugar for both loaves of bread?

Answers

3/4*2
=6/4
6/4/1/4
=6/4*4
=6
so 6 pours

Answer:

6 times

Explanation:

1- getting the number of times required for one loaf:

We know that:

The loaf requires 0.75 of a cup of sugar

The cup can hold 0.25 cup of sugar

To know the number of times required to get the needed amount, we will simply do cross multiplication as follows:

1 time ................> 0.25 of a cup

?? times ..........> 0.75 of a cup

Number of times for one loaf = $(0.75*1)/(0.25)$ = 3 times

2- getting the number of times required for two loaves:

We have calculated that one loaf requires filling the measuring cup 3 times, this means that:

2 loaves would require filling the cup 2*3 = 6 times

Hope this helps :)
