Answer:
Step-by-step explanation:
f(x) = y = 4x + 7
Solve for "x"
4x + 7 = y ⇒ x = [tex]\frac{1}{4}[/tex] y - [tex]\frac{7}{4}[/tex]
Exchange the places "x" and "y"
[tex]f^{-1}[/tex](x) = [tex]\frac{1}{4}[/tex] x - [tex]\frac{7}{4}[/tex]
or [tex]f^{-1}[/tex] (x) = [tex]\frac{x-7}{4}[/tex]
Lindsey’s goal is to sell at least 35 candles at each of 15 craft fairs.
She makes 24 candles each day for 20 days.
Explain whether Lindsey makes enough candles to reach her goal.
Group of answer choices
A.Lindsay makes 48 candles. She divides 48 by 24 to get 2. She does make enough candles.
B.Lindsay makes 440 candles. She divides 440 by 15 to get 29 R4. She does make enough candles.
C.Lindsay makes 44 candles. She divides 44 by 20 to get 2R 4. She does not make enough candles.
D.Lindsay makes 480 candles. She divides 480 by 15 to get 32. She does not make enough candles.
Answer: D.Lindsay makes 480 candles. She divides 480 by 15 to get 32. She does not make enough candles.
Step-by-step explanation: 24 times 20 is 480. That is how many she made all together.
Lindsay makes 480 candles. She divides 480 by 15 to get 32. She does not make enough candles and this can be determined by using the arithmetic operations.
Given :
Lindsey’s goal is to sell at least 35 candles at each of the 15 craft fairs. She makes 24 candles each day for 20 days.The following steps can be used in order to determine whether Lindsey makes enough candles to reach her goal:
Step 1 - The arithmetic operations can be used in order to determine whether Lindsey makes enough candles to reach her goal.
Step 2 - According to the given data, Lindsey makes 24 candles each day for 20 days. So, the total number of candles she makes at the end of 20 days is:
[tex]=24\times 20[/tex]
= 480 candles
Step 3 - Also it is given that Lindsey’s goal is to sell at least 35 candles at each of 15 craft fairs. So, the total candles required is:
[tex]=35\times 15[/tex]
= 525 candles
Therefore, the correct option is D).

Answer:
6 servings
Step-by-step explanation:
Let's say there are x 2/3 cup servings in a 4 cup container.
We multiply 2/3 by x to get the amount of cups that will produce and set that equal to 4 (because we want 4 cups):
(2/3) * x = 4
Divide both sides by 2/3, or multiply both sides by the reciprocal 3/2:
x = 4 * (3/2) = 12/2 = 6
The answer is 6 servings.

Which option? Help would be appreciated greatly
Answer:
Option 4: 6^7
Step-by-step explanation:
The rule is that when multiplying same bases with different exponents, the exponents only get added.
In other words, (x^a)(x^b)=x^(a+b)
In this case, (6^3)(6^4)=6^(3+4)=6^7
Therefore, Option 4 is correct

Draw the dilation of ABCD using center D and scale factor 1/3. Label the dilation EFGH
Answer:
Please find attached, the required drawing of quadrilateral ABCD and the dilation of quadrilateral ABCD scaled down by a scale factor of 1/3
Step-by-step explanation:
The coordinates of the quadrilateral ABCD are;
A(0, 6), B(6, 6), C(9, 0), D(0, 0)
From the dilation by a scale factor of 1/3, using D as the center of dilation, we have from the attached drawing, the following coordinates of the quadrilateral EFGH as E(0, 2), F(2, 2), G(3, 0) H(0, 0) which is the quadrilateral ABCD scaled down by 1/3
