Answer:
x ≤ 4/7
Step-by-step explanation:
Simplify the given 2x ≤ -2/3 (4x + 4) by multiplying both sides by (3/2):
(3/2)(2x) ≤ (3/2)(-2/3)(4x + 4)
We get 3x ≤ -4x - 4
Solve for x by combining like terms. Add 4x to both sides, obtaining
7x ≤ 4
and so the solution is the set
x ≤ 4/7
The function f(x) = (x - 4)(x - 2) is shown.
What is the range of the function?
O all real numbers less than or equal to 3
O all real numbers less than or equal to -1

A gold earring has a volume of 0.55cubic centimeters and a mass of 9.9grams. Calculate its density.
Answer:
.018 Kg/cm^3
Step-by-step explanation:
[tex]p = m \div v \\ [/tex]
Density (P) is equal to the mass (9.9g) divided by volume (.55cm^3)
[tex] = 9.9 \div .55[/tex]
= 18g/cm^3
=.018kg/cm^3
The density with given mass and volume is 18 g/cm³.
What is density?Density is the measurement of how tightly a material is packed together. It is defined as the mass per unit volume.
Given that, a gold earring has a volume of 0.55 cubic centimeters and a mass of 9.9 grams.
We know that, density =Mass/Volume
Density = 9.9/0.55
= 18 g/cm³
Therefore, the density with given mass and volume is 18 g/cm³.

10. The surface area of a cylinder with radius rand height h is twice the product of r and the
square of the radius plus twice the product of it, the radius, and the height.
Education
Financial Algebra, F
11
Step-by-step explanation:
The cylinder is a closed figure which consists of two circular ends. If r is the radius and h is the height of the cylinder, then its surface area is given by :
[tex]A=2\pi rh[/tex]
or
[tex]A=2\pi \times r\times h[/tex]
We also know that, surface area = perimeter×height
So, the surface area of the cylinder is the product of circumference of the circle and height of the cylinder.

Find the slope given the following points: (12,-2) and (4,-6)
The slope of the point (12,-2) and (4,-6) is; 1/2
What is the Point-slope form?The equation of the straight line has its slope and given point.
If we have a non-vertical line that passes through any point(x1, y1) and has a gradient m. then general point (x, y) must satisfy the equation;
y-y₁ = m(x-x₁)
we have been given two points (12,-2) and (4,-6).
Then the slope is;
m = (-6 - (-2))/ (4 - 12)
m = -4 / -8
m = 1/2
The equation of line is y + 2 = 1/2(x - 12)
Hence, the slope of the point (12,-2) and (4,-6) is 1/2.

Maria designs and sells bowling uniforms. She charges a design fee of $8 for a custom bowling shirt, and sells each shirt for $25 dollars. (a) Write an equation in slope-intercept form, where y represents the total cost and x represents the number of bowling shirts.
Answer:
y = 25x + 8
Step-by-step explanation:
The slope intercept equation has a standard form of;
y = mx + c
Now, we are told that She charges a design fee of $8 for a custom bowling shirt, and sells each shirt for $25 dollars.
And that y represents the total cost and x represents the number of bowling shirts.
Now, since x represents the number of bowling shirts, the cost of x bowling shirts is = 25x
Also, since design fee is $8, it means that total cost = 25x + 8
Writing this in slope intercept form;
y = 25x + 8

Which equation shows that 6 is a factor of 18?
Choose 1 answer:
A- 18 = 6 x 12
B- 18 = 24 - 6
C- 3 = 18 : 6
D- 6 = 18 x 3
To see if 6 is a factor of 18, we need to take the quotient between 18 and 6 and see if it is an integer, so the correct option is C.
How to know when a number is a factor of another number?
We say that the number a is a factor of b if and only if a divides b.
This means that the quotient:
b/a = integer number.
Then, to see if 6 is a factor of 18, we need to divide 18 by 6, and see if the quotient is an integer number.
We will get:
18/6 = 3
3 is an integer number, so yes, 6 is a factor of 18.
From this, we can conclude that the correct option is C.

I Which of the following is the most appropriate unit to describe the rate at which people are entering Disneyland?
A People per hour, because the dependent quantity is the people
B Hours per person, because the dependent quantity is the hours
C Hours per person, because the dependent quantity is the people
D People per hour, because the dependent quantity is the hours
Answer: D
Step-by-step explanation:
Answer:
d) People per hour, because the dependent quantity is the people
Step-by-step explanation:
In this situation, the two quantities are people and hours. These are the two things in this problem we can count or measure.
The independent variable is the one that causes a change, while the dependent variable is the one that gets changed. In this situation, the number of people change every hour; this means the number of people gets changed, which makes it the dependent variable. This means that the independent variable must be time.
Since people is dependent and time is independent, "people per hour" would be the best form of this statement.

Ann, Claire, and Josh collect stickers. One week, Ann collects 7 more stickers than Josh. Josh collects twice as many stickers as Claire. If they collect a total of 157 stickers, how many stickers did each collect?
Answer:
Claire = 30 stickers
Josh = 60 stickers
Ann = 67 stickers
Step-by-step explanation:
Let
Claire stickers= x
Josh = 2x
Ann= 2x + 7
Total stickers = 157
Total stickers = Claire stickers + Josh stickers + Ann stickers
157 = x + (2x) + (2x+7)
157 = x + 2x + 2x + 7
157 = 5x + 7
Subtract 7 from both sides
157 - 7 = 5x + 7 - 7
150 = 5x
Divide both sides by 5
150/5 = x
30 = x
x = 30
Claire stickers= x
=30 stickers
Josh = 2x
= 2(30)
= 60 stickers
Ann= 2x + 7
= 2(30) + 7
= 60 + 7
= 67 stickers
Claire = 30 stickers
Josh = 60 stickers
Ann = 67 stickers

Step-by-step explanation:
If you have any questions about the way I solved it, don't hesitate to ask =)
Answer:Solution for -5(p+3/5)=-4 equation:
-5(p+3/5)=-4
We move all terms to the left:
-5(p+3/5)-(-4)=0
We add all the numbers together, and all the variables
-5(+p+3/5)-(-4)=0
We add all the numbers together, and all the variables
-5(+p+3/5)+4=0
We multiply parentheses
-5p+4-3/5*5=0
We multiply all the terms by the denominator
-5p*5*5-3+4*5*5=0
We add all the numbers together, and all the variables
-5p*5*5+97=0
Wy multiply elements
-125p*5+97=0
Wy multiply elements
-625p+97=0
We move all terms containing p to the left, all other terms to the right

Gianna is taking a multiple choice test with a total of 100 points available. Each question is worth exactly 5 points. What would be Gianna's test score (out of 100) if she got 3 questions wrong? What would be her score if she got xx questions wrong?
Answer:
Her test score would be an 85 because 5x3=15 and then you would subtract 15 from 100 which would be 85
equation would be x=100-(5y)
Answer:
[tex]85[/tex]
Step-by-step explanation:
Let [tex]x[/tex] equal the number of questions.
Let's find how many total questions there are:
[tex]100=5x[/tex]
Divide by the coefficient of [tex]x[/tex], which in this case is [tex]5.[/tex]
[tex]20=x[/tex]
So we have a total of [tex]20[/tex] questions, each are worth [tex]5[/tex] points.
Now, Gianna got [tex]3[/tex] questions wrong, and if we know there are [tex]20[/tex] total questions...
[tex]20-3[/tex]
Solve.
[tex]20-3=17[/tex]
So we know Gianna got [tex]17[/tex] questions correct.
Let's use an expression to figure out her score.
Again, let [tex]x[/tex] equal the number of questions.
[tex]5x[/tex]
Substitute.
[tex]5(17)[/tex]
Multiply.
[tex]85[/tex]

A rational number can be expressed in the form
[tex]\frac{a}{b}[/tex] ← where a and b are integers
From the set
3 is rational as it can be expressed as [tex]\frac{3}{1}[/tex]
and [tex]\sqrt{9}[/tex] = 3 ← rational
[tex]\sqrt{2}[/tex], [tex]\sqrt{3}[/tex] and [tex]\sqrt{7}[/tex] ← are irrational numbers
Thus there are 2 rational numbers out of the 5 given, thus
P( rational ) = [tex]\frac{2}{5}[/tex] → B
