1/4(2x + 8) = –16
A)
-18
B)
-24
D
-28
D)
-36
Answer:
D
Step-by-step explanation:
Given
[tex]\frac{1}{4}[/tex] (2x + 8) = - 16
Multiply both sides by 4 to clear the fraction
2x + 8 = - 64 ( subtract 8 from both sides )
2x = - 72 ( divide both sides by 2 )
x = - 36
Answer:
The answer is option DStep-by-step explanation:
[tex] \frac{1}{4} (2x + 8) = - 16[/tex]First multiply through by 4
That's
[tex]4 \times \frac{1}{4}(2x + 8) = - 16 \times 4 \\ 2x + 8 = - 64[/tex]Subtract 8 from both sides
We have
[tex]2x + 8 - 8 = - 64 - 8 \\ 2x = - 72[/tex]Divide both sides by 2
That's
[tex] \frac{2x}{2} = - \frac{72}{2} [/tex]We have the final answer as
x = - 36Hope this helps you
Click on the graph until the graph of a line with undefined slope appears.
Answer:
The graph with the vertical line.
Step-by-step explanation:
All vertical lines have an undefined slope. Horizontal lines have zero slope, and diagonal lines have a slope.
When calculating a slope for a vertical line, you would have to divide by zero. The quotient of any number and 0 are undefined, as you cannot divide by zero. This is what makes vertical lines have an undefined slope.
Hope this helps.

soolve the abslut value of |2x-1|=3
Answer: x = 2 or x = -1
Step-by-step explanation: When you are solving an absolute value equation, you can split the problem up into two separate equations.
The first equation will look just like the original problem,
except for the absolute value signs (2x - 1 = 3).
The second equation will look just like the first,
but the right side will be changed to a negative (2x - 1 = -3).
Now solve each equation from here to get x = 2 or x = -1
A jar contains 16 black balls,13 blue balls and 2 red balls in a bag. A ball is drawn in random. Find the probability of drawing a black ball? Find the probability of drawing a blue ball? Find the probability of not drawing a red ball?
Answer:
black: 16/31 blue: 13/31 red 2/31
16 black, 13 blue, 2 red
16+13+2 = 31 total
16/31 is the probability of picking black
13/31 is the probability of picking blue
2/31 is the probability of picking red, so 29/31 is the probability of not picking red (since 31-2 = 29 are not red out of 31 total)
Owen knows he only has three pencils in his backpack, and they are all yellow. He reaches into his backpack without looking and takes out a pencil. What is the probability that the pencil was yellow? Answer options with 5 options A. 0-thirds B. 1-third C. 2-thirds D. 3-thirds E. 3 over 1 I NEED ACTUAL ANSWERS NOT JUST STUPID PEOPLE WITH A POOR SENSE OF HUMOR
Answer:
D; 3-thirds
Step-by-step explanation:
Here is a probability question.
Firstly, we need to understand that the probability of any event is between 0 and 1; it cannot be negative and cannot be more than 1.
So the probability we want to calculate here is simply the probability of drawing a yellow pencil.
The way to go about this is by dividing the number of yellow pencils by the total number of pencils
Mathematically;
Probability of bringing out a yellow pencil= Number of yellow Pencils/ Total number of pencils
From the question, we are told that the number of pencils = number of yellow pencils = 3
Thus the probability will be 3/3 = 1
This cannot be found in the options right?

Write 6 x 10 x 10 x 10 x 10 with an exponent.
Answer:
the answers is 6x 10 4
Step-by-step explanation:
The expression 6 x 10 x 10 x 10 x 10 with an exponent would be written as 6(10^4).
What are exponents?The exponents of a number are defined as the representation of a number that shows how many times a number is multiplied by itself.
If we have a^b then 'a' is called base and 'b' is called power or exponent and we call it "a is raised to the power b" (this statement might change from text to text slightly).
We have been given an expression as
6 x 10 x 10 x 10 x 10
Here we can see the base 10 multiplied by itself 4 times.
Exponentiation(the process of raising some number to some power) have some basic rules as:
[tex]a^{-b} = \dfrac{1}{a^b}\\\\a^0 = 1 (a \neq 0)\\\\a^1 = a\\\\(a^b)^c = a^{b \times c}\\\\ a^b \times a^c = a^{b+c} \\\\^n\sqrt{a} = a^{1/n} \\\\(ab)^c = a^c \times b^c\\\\a^b = a^b \implies b= c \: \text{ (if a, b and c are real numbers and } a \neq 1 \: and \: a \neq -1 )[/tex]
The expression 6 x 10 x 10 x 10 x 10 with an exponent would be written as 6(10^4).

Dr. Ames earns an annual salary of $265,000. If social security is 8% of your income, then how much will Dr. Ames pay each year in social security? $13,250 $21,200 $15,900 $18,40063
Answer:
The correct answer is b.
Step-by-step explanation:
Giving the following information:
Annual salary= $265,000
Social security is 8% of his income.
To calculate the annual expending on social security, all we have to do is multiply the annual salary for the expend percentage.
Annual expense= 265,000*0.08

Answer:
I don't think so
Step-by-step explanation:
If being over 200 lbs makes you a good football player, then Earl could be a good player. But you need to be skilled at football to be good at it. Your weight doesn't make you good at something. So in my opinion, I don't think Kaylie's conclusion is valid.

y = -0.2*x^2 is a vertical dilation of scale factor 0.2 followed by a reflection over the x-axis of y = x^2
How to relate these two graphs?
We have two functions:
f(x) = x^2
g(x) = -0.2*x^2
The transformations used are:
Reflection over the x-axis.
For a function f(x), a reflection over the x-axis is written as:
g(x) = -f(x).
Vertical dilation.
For a function f(x), a vertical dilation of scale factor k is written as:
g(x) = k*f(x).
So here we can see that we have a vertical dilation of scale factor 0.2, followed by a reflection over the x-axis.
g(x) = -0.2*f(x).
So, g(x) opens in the opposite direction than f(x), and grows slower (because of the dilation).

Tina has 1/2 of a pan of cornbread left from a dinner party. She eats 1/2 of the leftover part the next night. How much of the whole pan does tina eat? Write and solve this equation
Answer:
Tina ate 3/4 of the whole pan of cornbread.
Step-by-step explanation:
Let the amount of cornbread in the initial pan be x.
After the dinner party, Tina has 1/2 of x left; That is 1/2x
If she eats 1/2 of the leftover, that will be 1/2 of 1/2x that is eaten. This will be 1/4x that is eaten.
To find the potion of the whole pan that Tina ate, we will add the potion she ate during the party to the portion of the leftover she ate the next night.
That will be 1/2x + 1/4x =3/4x
Therefore, Tina ate 3/4 of the whole pan of cornbread.

Ava has 34 candy bars. If
a box contains 5 bars and she has 4 extra candy bars
determine how many boxes
She has?
[tex]\bf Step-by-step~explanation:[/tex]
If Ava has 34 candy bars, and each box can hold 5 bars, then we need to find out how many boxes that are filled up.
[tex]\bf Step~1:[/tex]
Divide the number of candy bars (34), by the number each box can hold (5)
[tex]\bf\frac{34}{5}=6.8[/tex]
Since we cannot have 6.8 boxes, we have to round down to 6.
[tex]\boxed{\bf Our~final~answer:~6~boxes}[/tex]
[tex]\bf Check~our~answer:[/tex]
To check our answer, we multiply the number of boxes (6), by the number of bars in each box (5), to get 30. We add Ava's extra bars (4), and we get the number we started off with: 34. This proves our answer is correct!

The path of water from a hose on a fire tugboat can be approximated by the equation y=-0.0055x^2 +1.15x + 5, where y is the height above the ocean and x is the distance from the tugboat. When the water is 6 ft above the ocean how far is it from the tugboat
Answer:
The water is 208.22ft from the tug boat
Step-by-step explanation:
The governing equation is [tex]y=-0.0055x^2 +1.15x + 5[/tex]
y is the height above the ocean
x is the distance from the tugboat
if y= 6ft, the equation will now become
[tex]6=-0.0055x^2 +1.15x + 5[/tex]
we can arrange this properly to form a quadratic equation by grouping like terms.
[tex]-0.0055x^2 +1.15x -1=0[/tex]
solving quadratically we have two values of x as 208.22ft and 0.873 ft.
We can take a more realistic value as a solution to our problems:
208.22ft
If anybody is good at math please help me out.
Step-by-step explanation:
The general equation of a straight line graph is y = mx + c, where m is the gradient of the line and c is the y-intercept.
Gradient = (2 - (-18)) / (3 - (-2)) = 20/5 = 4.
So y = 4x + c.
When x = 3, y = 2. (Given in the question)
This means that 2 = 4(3) + c, hence c = -10.
The answer is y = 4x - 10.
