Given the equation y = 4x - 3.A) If x increases by 1 unit, what is the corresponding change in y? B) If x decreases by 5 units,

DedPeter [7]

Answer:

A) y will increase by 4 unit.

B) y will decrease by 20 units

Step-by-step explanation:

Given equation that shows relation between x and y.

$y=4x-3$

A) If x is increased by 4 units

New value of y = $4(x+1)-3$

$=4x+4-3$

$=4x+1$

So, change in y = new value of y- original value of y

$=4x+1-(4x-3)$

$=4x+1-4x+3$

$=4$

Thus, the value of y will be increased by 4 units.

B) If x is decreased by 5 units

New value of y = $4(x-5)-3$

$=4x-20-3$

$=4x-23$

So, change in y = new value of y- original value of y

$=4x+1-(4x-3)$

$=4x-23-(4x-3)$

$=4x-23-4x+3$

= -20

Thus, the value of y will be decreased by 20 units.

Out of 20 cookies, 3/4 are chocolate chip. How many cookies are chocolate chip?

DedPeter [7]

Answer:

15 cookies are chocolate

Step-by-step explanation:

Well it's actually quite easy, just think about it this way. 20/4=5 since there's a 4 as the denominator in the fraction. Or there's many other ways to find the answer. At the end of the day, you'll get the same answer just some ways are harder especially compared to the one I did.

Since we divided 4 into 20, we know the answer to that is 5.

3/4=15 if you think about it in a certain way.

Therefore the answer is 15 since 3x5= 3/4 and both of those equal 15

Hope this helps
