Answer:
-3 X (x^2 - 8)
Step-by-step explanation:
put "the square of a number decreased by 8" in parentheses so when -3 is multiplied with that, it does not get multiplied with y^2 and -8.
anytime you see "a number" in a sentence, put it as a random variable, in this case, I decided it should be "x".

Evaluate the following expressions, assume the following declarations: int x = 4; int y = 9 / 2; int num = 6; num *= x y; what is the value of the num after expression is evaluated?
The value of the num will be 18 after the expression is evaluated.
What is an expression?Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that int x = 4; int y = 9 / 2; int num = 6; num *= x y; the value of num after the evaluation of the expression will be:-
num = x y
num = [ ( 4 x ( 9 / 2 ) ]
num = 9 x 2
num = 18
Therefore, the value of the num will be 18 after the expression is evaluated.

Chose the step below that correctly uses the distributive property to begin solving the equation: 2(x + 1) + 4 = 8 O 2x+5=8 Ox+1+2 = 4 O 2x + 2 + 4 = 8 O 2x + 1 + 4 = 8
2(x+1)+4
Distributive property : According to this property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.
solve equation by using distributive property we should use laws of this property that are as follows:
Expand the equation. Multiply (distribute) the first numbers of each set, outer numbers of each set, inner numbers of each set, and the last numbers of each set. Combine like terms.
2(x + 1) + 4 = 8
2(x)+2(1)+4=8
2x+2+4=8
2x+6=8
2x=8-6
2x=2
x=2/2
x=1
so final conclusion is Option A 2(x+1)+4=8 is the right answer

greg is 5yr. older than randy, who is 3yr. older than Wilson. the sum of their ages is 32. how old is greg
The ages of Wilson, Randy and Greg given their total ages is 7, 10 and 15 years respectively.
This means that the total ages of Wilson, Randy and Greg is 7 years, 10 years and 15 years.
AlgebraLet's represent the information above as follows:
Wilson's age = xRandy's age = (x + 3)Greg = (x + 3) + 5Total ages = 32The total ages = Wilson + Randy + Greg
That is, Wilson's age, Randy's age and Greg's ages is given as:
32 = x + (x + 3) + (x + 3) + 5
32 = x + x + 3 + x + 3 + 5
32 = 3x + 11
32 - 11 = 3x
21 = 3x
x = 21/3
x = 7 years
Therefore, from the calculations above,
Wilson's age = x
= 7 years
Randy's age = (x + 3)
= 7 + 3
= 10 years
Greg = (x + 3) + 5
= (10) + 5

Diego worked the SAME number of hours for FIVE days at his job at the cheese factory plus an extra 7 hours on Saturday. He worked a total 52-hours last week.
Using H as a variable for the number of hours he worked each normal day, model (create an equation) for Diego’s work week.
How many hours did he work each day for his normal work week?
The total hours worked on each day of his normal work week is 7.5 hours.
How many hours did Diego work on each normal day ?The total hours worked is a function of the total hours worked during the week and the hours worked on Saturday.
The equation that represents the total hours that Diego worked is:
Total hours = total hours worked during the five days + hours worked on Saturday
52 = (5 X H) + 7 + H
52 = 5H + 7 + H
In order to determine the value of H, take the following steps:
Combine similar terms together: 52 - 7 = 5H + H
Add similar terms together: 45 = 6h
Divide both sides of the equation by 6 : H = 45 /6
H = 7.5 hours

Based on the graph above, estimate (to one decimal place) the average rate of change from x = 1 to
x = 5.
The Average Rate of change of a function f on the interval [a , b] is given by
[tex]r=\frac{f(b) - f(a)}{b-a}[/tex]
Now, the given interval is [1, 5]
⇒ b=5 and a = 1
Since, the graph passes through (1, 3) and (5, 5)
⇒ f(1) = 3 and f(5) = 5
Thus,
[tex]r=\frac{f(5) - f(1)}{5-1}[/tex]
[tex]r=\frac{5- 3}{4}[/tex]
[tex]r=\frac{2}{4}[/tex]
[tex]r=\frac{1}{2}[/tex]
[tex]r=0.5[/tex]
∴ The Average Rate of change of the graph is equal to 0.5

The midpoint AB is (1,2). The coordinates of A are (-3,6) Find the coordinates of B
Can someone help me with this exercise and show me the procedure of how to do it??
========================================================
Explanation:
We have these points
A = (-3,6)M = midpoint = (1,2)B = (x,y)Focus on the x coordinates for now.
The x coordinates of A and B are -3 and x in that order. Add them up and divide in half to get the x coordinate of the midpoint M
(-3+x)/2 = 1
-3+x = 2*1
-3+x = 2
x = 2+3
x = 5
Repeat for the y coordinates
(6+y)/2 = 2
6+y = 2*2
6+y = 4
y = 4-6
y = -2
Therefore, the location of point B is (5, -2)

Anna took a taxi from her house to the airport. the taxi company charged a pick-up fee of $3 plus $2.25 per mile. the total fare was $48, not including the tip. how many miles was the taxi ride?
Answer:
20
Step-by-step explanation:
The total fare, f, is:
f = 2.25x + 3
We want to solve for x. the number of miles. This is fairly simple if we know f.
48 = 2.25x + 3
48 - 3 = 2.25x + 3 - 3
45 = 2.25x
45/2.25 = 2.25x/2.25

Rectangle ABCD is shown above. Which of the following expressions
can be used to determine the length of diagonal AC?
O√64 - w²
O√64+w²
O 64-w²
O 64+w²
The length of the diagonal AC can be calculated using equations:
= √(64 + W²).
The correct option is B.
What exactly is the Pythagorean Theorem?The Pythagorean theorem states that the total of the squares upon that legs of a right triangle equals the square upon that hypotenuse (the side opposite this same right angle)—or, in popular algebraic notation:
a² + b² = c².
According to the given data:The length of the rectangle = 8
The width of the rectangle = w
The hypotonus of the rectangle = p
Using the Pythagoras formula:
P² = L² + W²
P = √(L² + W²)
Putting the value of Length = 8
P = √(8² + W²)
P = √(64 + W²)
The length of the diagonal AC can be calculated using equations:
= √(64 + W²).

The number of hours needed for the second press to complete the job is 3 hours.
What is an equation?An equation represents the relationship of two expressions on either side of the sign
Given that together they can complete a job in 2 hours and one takes 6 hours to complete the work alone.
If we let x = amount of time required for the second press to complete the job alone
We can write as:
Second press work = 1/x of the job per hour.
First press work = 1/6 of the job per hour.
Together work = 1/2 of the job per hour.
We can write the equation as:
1/6 + 1/x = 1/2
1/x = 1/2 - 1/6
1/x = (3 - 1)/6

All rhombus are parallelograms, parallelogram have exactly two pairs of parallel lines, therefore all rhombus have exactly two pairs of parallel lines, so option A is correct.
What is parallelogram?
A unique kind of quadrilateral created by parallel lines is called a parallelogram. A parallelogram can have any angle between its neighboring sides, but for it to be a parallelogram, its opposite sides must be parallel.
A quadrilateral with two sets of parallel sides is referred to as a parallelogram. Every rhombus is a parallelogram because its opposite sides are all parallel. But all parallelograms cannot be rhombus as a rhombus have all sides equal.
Both a square and a rhombus have equal numbers of sides. The square's diagonals are also perpendicular to one another and divide the opposing angles. A square is a rhombus as a result.
Thus, all rhombus are parallelograms as they have one pair of parallel sides.

Graph y=0.2x use the graph to find the value of x when y=-2,0,2
By graphing the equation y = 0.2x, we find that x is equal to -10 when y is -2, x is equal to 0 when y is 0, and x is equal to 10 when y is 2.
To graph the equation y = 0.2x, we can plot a few points and then connect them to create the line.
Let's calculate the corresponding values of x when y takes on the values of -2, 0, and 2:
When y = -2:
-2 = 0.2x
x = -2 / 0.2
x = -10
When y = 0:
0 = 0.2x
x = 0 / 0.2
x = 0
When y = 2:
2 = 0.2x
x = 2 / 0.2
x = 10
Using these values, we can plot the points (-10, -2), (0, 0), and (10, 2) on the coordinate plane. Drawing a line passing through these points, we obtain the graph of the equation y = 0.2x.
The graph will be a straight line that passes through the points (-10, -2), (0, 0), and (10, 2). The line will have a positive slope, indicating that as x increases, y increases at a slower rate.
The graph visually represents the relationship between x and y according to the equation y = 0.2x. It shows that for every increase of 1 unit in x, y increases by 0.2 units.
