Keith had $10. When he bought 5 colored pencils and 3 notebooks at $1.50 per notebook,
the change was $2.
What is the price of 1 colored pencil?

The price of one colored pencil was $0.70

Step-by-step explanation:

Let p be the price of 1 colored pencil:

We know he bought 5 colored pencils and 3 notebooks and had 2 dollars left over, meaning he spent 8, so we can write out:

5p + 3(1.5) = 8

That becomes:

5p + 4.5 = 8

Isolate p by moving 4.5 to the right:

5p = 3.5

Divide by 5

p = 0.7

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
