Step-by-step explanation:

f(x)=4x+7

y = 4x+7

4x = y-7

x = (y-7) /4

the correct answers are:

=> f`¹(x) = (x-7) /4 (a)

=> x - 7 = 4y (e)

=> (x-7) /4 = y (f)

=> x = 4y +7 (g)

Answer:

$f(x) = 4x + 7 \\ y = 4x + 7 \\ 4x = y - 7 \\ x = \frac{y - 7}{4} . \\ \\ the \: correct \: answers \: are \: \\ \\ f {}^{ - 1} (x) = \frac{(y - 7)}{4(a)} . \\ x - 7 = 4y(e). \\ \frac{(y - 7)}{4} = y(f). \\ x = 4y + 7(g).$

PLA HELP ME ASAP FOR 7, 8, and 9 (SHOW WORK!) POINTS!!!

kykrilka [37]

7.D is the correct answer. I simplified 12/27 to 4/9 then i try to see if 4/9 is equivalent to 20/45 and it is you multiply 4 and 9 by 5= 20/45

8. 1.4*2.1=2.94 then 2.94/1.5= 1.96 so c=1.96

9. Explanation You multiply- 5/8 * 3/5 then divide = answer divided by 2/3

Solving: 5/8*3/5= 3/8 then 3/8 divided by 2/3, flip second number and then switch the division sign to multiplication sign so it should be like this : 3/8 * 3/2= 9/16
answer= 9/16

E = {1, 2, 3}

gtnhenbr [62]

E ∩ F = {}

Step-by-step explanation:

Intersection is an operation performed on sets. In intersection, the common elements of the sets involved are written,

Given

E = {1, 2, 3}

F = {101, 102, 103, 104}

We have to find the intersection of both sets as indicated

So,

E ∩F = {1, 2, 3} ∩ {101, 102, 103, 104}

E ∩ F = {}

As there are no common elements in both sets the intersection will be an empty set

The drama club is selling short-sleeved shirts for $5

Angelina_Jolie [31]

The system of the equation that represents the situation is 5x + 10y = 1750, (1/3)x + (1/2)y = 100, and the number of short-sleeved shirts that were ordered is 150 and long-sleeved is 100.

<h3>What is a linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have:

The selling price of long-sleeved shirts for $10 each.

The selling price of short-sleeved shirts for $5 each.

Now,

5x + 10y = 1750

$\rm \dfrac{1}{3}x+\dfrac{1}{2}y=100$

After solving both equations:

x = 150

y = 100

Thus, the system of the equation that represents the situation is 5x + 10y = 1750, (1/3)x + (1/2)y = 100, and the number of short-sleeved shirts that were ordered is 150 and long-sleeved is 100.
