: In order to solve the inequality -1/4 x > 8, which of the following steps must be done?
1.divide by -4 and keep the inequality symbol
2.divide by -4 and flip the inequality symbol
3.multiply by -4 and keep the inequality symbol
4.multiply by -4 and flip the inequality symbol
Multiply by -4 and flip the inequality symbol. The correct option is D.
What is inequality?When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relation between variables and the numbers.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Here are the steps to solve the whole equation of -1/4x > 8:
Simplify the fraction to x/4
Multiply both sides by 4
Multiply 8 x 4 so it can be 32
Multiply both sides by -1
The value of x is less than -32.

Find the number of ways 4 members from a family of 5 can line up for a photo shoot?
Final answer:
There are 120 different ways for 4 members out of a family of 5 to line up for a photo shoot. This is calculated using permutations, where the order of members matters, and is found by the formula 5! / (5-4)!.
Explanation:
To find the number of ways 4 members from a family of 5 can line up for a photo shoot, we use the concept of permutations since the order of arrangement matters.
In mathematics, the number of permutations for selecting r objects from a set of n objects is given by nPr, which is calculated as n! (n factorial) divided by (n-r)! (the factorial of the difference between n and r).
In this case, we want to arrange 4 out of 5 family members, so n = 5 and r = 4. The permutation formula gives us:
5P4 = 5! / (5-4)! = (5 × 4 × 3 × 2 × 1) / 1 = 120 ways.
Therefore, there are 120 different ways for 4 members out of a family of 5 to line up for a photo shoot.
The measure of an angle is 79°. what is the measure of a supplementary angle?
Hence, the supplement angle is [tex]101[/tex] degree.
What are the angles?
Angles are an integral facet in the study of mathematics, particularly geometry. Angles are formed by two rays (or lines) that begin at the same point or share the same endpoint.
The point at which the two rays meet (intersect) is called the vertex.
Here given that,
The measure of an angle is [tex]79[/tex] degree.
Let the supplement angle is [tex]x[/tex]
As we know that the supplement of an angle is [tex]180-x[/tex].
[tex]180-x=180-79[/tex]
[tex]=101[/tex] degree.
Hence, the supplement angle is [tex]101[/tex] degree.

Final answer:
The measure of a supplementary angle to one that measures 79° is 101°, since supplementary angles sum up to 180°.
Explanation:
If the measure of an angle is 79°, the measure of a supplementary angle can be found by subtracting this angle from the total degrees in a straight line. In other words, the sum of the measures of supplementary angles is 180°. Therefore, to find the measure of a supplementary angle when one angle measures 79°, we perform the following calculation:
180° - 79° = 101°
So, the measure of the supplementary angle is 101°.

How many subsets of exactly two elements does a set of five elements have?
A.10
B.26
C.7
D.32
Option: A is the correct answer.
A. 10
Step-by-step explanation:We know that the number of subsets of exactly ''r'' elements that is formed by the help of n elements is calculated by:
[tex]n_C_r[/tex]
Since here we have to chose 2 elements out of the 5 elements in order to form a subset.
Hence, we have: n=5 and r=2
Hence, the number of subsets are:
[tex]5_C_2=\dfrac{5!}{2!\times (5-2)!}\\\\\\5_C_2=\dfrac{5!}{3!\times 2!}\\\\\\5_C_2=10[/tex]
Hence, the number of subsets are:

How to solve a multiplication problem with a variable?
Example Question: 6x + 4 = 22
The goal in this is to get the variable alone and these are the steps how to. What you have to do is subtract 4 from 4 so that you can get 6x alone. But when you subtract 4 from one side, you have to subtract 4 from the other side too which leaves us with 6x = 18. Now, we have to do the opposite of multiplication which is division. So we are going to do 6x divided by 6 and the two sixes cancel each other out. But remember, if you do something to one side you have to do it to the other as well. So we have to do 18/6 which leaves us with the answer.

Choose the correct transformation of the graph f(x) = |x + 8| - 3.
The graph of f(x) = x| is shifted to the left 8 units, down 3 units.
The graph of f(x) = x| is shifted to the right 8 units, down 3 units.
The graph of f(x) = x| is shifted to the left 8 units, up 3 units.
The graph of f(x) = x| is shifted to the right 8 units, up 3 units.
Answer:
A. The graph of f(x) = |x| is shifted to the left 8 units, down 3 units.
Step-by-step explanation:
We are given,
The transformed function is [tex]f(x)=|x+8|-3[/tex].
Now, the parent function is [tex]f(x)=|x|[/tex].
So, we have,
When the parent function is shifted 8 units to the left, the function is [tex]|x+8|[/tex].
This function when translated 3 units downwards gives [tex]f(x)=|x+8|-3[/tex].
Thus, we get,
The parent function f(x)=|x| is translated 8 units to the left and 3 units downwards.So, option A is correct.
Marta believes that the equation of the line of best fit for the scatterplot below is y=-5/9x+23/9. Which statement best summarizes why Marta is likely incorrect?
Marta’s equation has a positive y-intercept, but the scatterplot suggests a negative y-intercept.
Marta’s equation has a positive y-intercept, but the scatterplot shows a negative correlation.
Marta’s equation has a negative slope, but the scatterplot suggests a negative y-intercept.
Marta’s equation has a negative slope, but the scatterplot shows a positive correlation.
The correct option is a.
Marta is likely incorrect because her equation has a positive y-intercept, but the scatterplot suggests a negative y-intercept.
Explanation:Marta is likely incorrect because her equation has a positive y-intercept, but the scatterplot suggests a negative y-intercept. The y-intercept is the value of y when x equals zero, so if the scatterplot shows a negative y-intercept, it means that when x is zero, y is negative. However, Marta's equation predicts a positive y value when x is zero, which contradicts the scatterplot.

Answer:
The equation that identify the situation is:
d= x + y
d= 15+38
d= 53
She brought 53 drawings.
Step-by-step explanation:
We know that Rosa brought d numbers of drawings to an art show.
She sold 15 of them and she had 38 left.
The number d of drawings that she brought to an art show is:
d= x + y
Where:
d: number of drawings she brought
x: number of drawing she sold
y: number of drawings she had left
d= 15+38
d= 53
She brought 53 drawings.
