Answer:
(A) h(x) = 1/4x -2
Step-by-step explanation:
Given: f(x)=4x+8
Rewrite with y: y=4x+8
Switch x and y: x=4y+8
Solve for y: x-8=4y
(x-8)/4=y
1/4x-2=y
y=1/4x-2
This means that h(x) = 1/4x -2 is the correct answer
Answer:
The number of unsold cakes was 2
Step-by-step explanation:
<u><em>The question in English is</em></u>
In the school Francisco I. Madero of Ciudad Delicias, the celebration was held for commemorate the arrival of spring, after the parade the stalls were set up of the kermesse. The first grade group bought 8 cakes and sold 3/4 of the total.
How much of the cake was not sold?
Let
x ----> number of cakes sold
y ----> number of cakes that didn't sell
we know that
The first grade group bought 8 cakes
so
-----> equation A
The first grade group sold 3/4 of the total.
so
---> equation B
substitute equation A in equation B

Find the value of y


therefore
The number of unsold cakes was 2
yes!! glad that you support this! keep your head up and keep on smiling! <3
Answer:
(7x+2)(3x-1); (5x+4)^2 or (5x+4)(5x+4);
Step-by-step explanation:
formula to find area is L* W = A ; meaning length multiplied by width equals to the area.
21.
using the formula to find area...
l*w=a
(7x+2)(3x-1) would be your answer
btw, don't put the "=a" at the end, since it's an expression :))
22.
since the problem states that it's a square, you can just say either...
(5x+4)^2 or (5x+4)(5x+4) not sure which one your teacher accepts
