Answer:
y = 3
Step-by-step explanation:
We need to solve the below proportion in this problem,
First of all, we cross multiply both sides such that,
Dividing both sides by 18.
For the above proportion, we find that the value of y is equal to 3.
Answer:
300%
Step-by-step explanation:
By increasing the down payment from 1,000 to 4,000, how does the total purchasing cost change?
If down payment is increased from 1000 to 4000
Icecrement = 4000-1000
Increment =3000
Percentage increase = 3000/1000×100
Percentage increase = 3000/10
Percentage increas=300%
Answer:
<h2>z = - 7</h2>
Step-by-step explanation:
<u>Move -1 to the right side of the equation</u>
<u>Divide both sides by 2</u>
We have the final answer as
<h3>z = - 7</h3>
Hope this helps you
Answer:
For functions, the two notations mean the exact same thing, but "f (x)" gives you more flexibility and more information. You used to say "y = 2x + 3; solve for y when x = –1". Now you say "f (x) = 2x + 3; find f (–1)" (pronounced as "f-of-x equals 2x plus three; find f-of-negative-one").
