Hi there!
To some this problem, we need to divide the y total amount of cloth she has with the amount of cloth she needs per blouse.
20 ÷ 2.5 = 8
So, the answer is 8 blouses.
Hope this helps!
Answer:
-26-8i does this help?
Step-by-step explanation:
I took what was in the parenthesis and put them together coming out with -10 and -4i. Then I took what was next and started putting the variables together and the numbers together.
Answer:
(2,-2)
Step-by-step explanation:
To solve this using substitution you would take your second equation and plug it in for y of the first equation (4x-10= -3x+4). You then would add the 10 over (4x= -3+14). Next you add the 3x over(7x=14). Finally divide both sides by 7, which should give you x=2. Now all you have to do is plug the two in for x in one of your equations (which ever equation you prefer) (y=-3(2)+4). Solve the equation and you will then have the answer to y, which you can then put into a point.

Step-by-step explanation:
Answer:
Option a - f(x)=20x
Step-by-step explanation:
Given : For a certain function f = f(x), we know that f is proportional to x and that the constant of proportionality is 20.
To Find : A formula for f ?
Solution :
We have given that,
f is proportional to x i.e.
This implies
Where, k is the proportionality constant
The constant of proportionality is 20.
So,
On comparing with, f = f(x)
Therefore, The formula of f is
So, Option a is correct.
