Answer:
The value of x = 12, makes the statement [tex]3x=2x+12[/tex] true
Option D is correct option.
Step-by-step explanation:
What value of x makes this statement true?
[tex]3x=2x+12[/tex]
We need to solve the equation to find value of x
[tex]3x=2x+12[/tex]
Subtract 2x on both sides
[tex]3x-2x=2x+12-2x\\x=12[/tex]
So, the value of x is: x=12
So, The value of x = 12, makes the statement [tex]3x=2x+12[/tex] true
Option D is correct option.
Select the lines that represent functions.
Answer:
All of them except the squiggly one and the vertical one
Step-by-step explanation:
The rest are functions, two of them are lines, and the curved swoop is a parabola, which is also a function
Function is a set of relation without same or repetitive domain. Because we are checking if the following graphs are function or not. It is easier to do line test.
How to check if the graphs are function.
Draw a vertical line.If the line passes or intercepts the graph only one point. The graph is function.If the line passes or intercepts the graph more than a point. The graph is not a function.Overall, the graphs that are not function are the vertical line and the vertical curve graph.
AnswerA horizontal lineA line with slope or steepnessParabola aka curve graph (The graph is not a line. The question asks for lines which represent functions. I am not sure if they want all graphs that are function or just lines that are functions. A Parabola graph is also a function but not a line graph.)Feel free to ask if you are confused.
Substitute teachers with Lexington School District get paid by the day, although subs with teaching credentials earn a different amount than subs without credentials. Yesterday, 3 non-credentialed subs and 2 credentialed subs taught in the district. That cost the district $368. Today, 11 non-credentialed subs and 7 credentialed subs taught, receiving $1,316 from the district. How much do subs get paid?
One cylinder has a volume that is 8 Centimeters cubed less than StartFraction 7 over 8 EndFraction of the volume of a second cylinder. If the first cylinder’s volume is 216 Centimeters cubed, what is the correct equation and value of x, the volume of the second cylinder?
StartFraction 7 over 8 EndFraction x + 8 = 216; x = 182 centimeters cubed
StartFraction 7 over 8 EndFraction x minus 8 = 216; x = 196 centimeters cubed
StartFraction 7 over 8 EndFraction x + 8 = 216; x = 238 centimeters cubed
StartFraction 7 over 8 EndFraction x minus 8 = 216; x = 256 centimeters cubed

At what point do the lines y= 2x + 3 and y = 5x - 9 intersect?
Answer:
(4,11)
Step-by-step explanation:
y=2x+3
y=5x-9
the first equation is equal to the second equation so
2x+3=5x-9
put like terms together
2x-5x= -9-3
-3x= -12
divide both sides by -3
.•.x=4
now, use the value of x to find the value of y like this:
y=2x+3 (x=4)
y=2(4)+3
y=8+3
y=11
therefore, the two lines intersect at the point (4,11)

Solve the inequality 24 + 4x ≥ 100
Answer:
x ≥ 19
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtract Property of EqualityStep-by-step explanation:
Step 1: Define
24 + 4x ≥ 100
Step 2: Solve for x
Subtract 24 on both sides: 4x ≥ 76Divide 4 on both sides: x ≥ 19Here we see that any value x greater than or equal to 19 would work as a solution to the inequality.

Answer:
The scale factor is 1 to 3
Step-by-step explanation:
Here, we want to get the scale factor
we can use the coordinates of the vertices of the small image and the vertices of the large image to get this
We have;
(2,5) going on to give (6,15)
As we can see, the vertices of the small shape are multiplied by 3 to give that of the big shape
So also we can see for the other vertices
This means that the scales factor is 1 to 3

Robert gets a loan from his bank.
He agrees to borrow £6000 at a fixed annual simple interest rate of 7%.
He also agrees to pay the loan back over a 10 year period.
How much money in total would he have paid back in 10 years?
Answer:
£10,200
Step-by-step explanation:
Simple interest = principal × rate × time
Principal = £6000
Rate = 7% = 0.07
Time = 10 years
Simple interest = principal × rate × time
= £6000 × 0.07 × 10
= £4,200
Total = simple interest + principal
= £4,200 + £6,000
= £10,200
He would have to pay back a total of £10,200 in 10 years

Shani borrowed $5000 at an annual interest rate of 4% compounded yearly. William borrowed the same amount of money at an annual interest rate of 6% compounded yearly. How much more interest will William pay than Shani at the end of 3 years?
Answer: William will pay $ 330.76 more interest than Shani at the end of 3 years.
Step-by-step explanation:
Compound interest = [tex]P((1+r)^t-1)[/tex] , P= principal , r= rate of interest , t= time
Given: P = $5000 , t= 3 years
For Shani , r= 4% = 0.04
Compound interest = [tex]5000((1+0.04)^3-1)[/tex]
[tex]=5000(1.124864-1)\\\\=5000(0.124864)\\\\=\$\ 624.32[/tex]
For William, r= 6%= 0.06
Compound interest = [tex]5000((1+0.06)^3-1)[/tex]
[tex]=5000(1.191016-1)\\\\=5000(0.191016)\\\\=\$\ 955.08[/tex]
Difference = $ ( 955.08- 624.32)
= $ 330.76
Hence, William will pay $ 330.76 more interest than Shani at the end of 3 years.

Complete Question
Minor arc KL measures 135°. Circle O is shown. Line segments K O and O L are radii. Which is the radian measure of central angle KOL?
a) StartFraction 3 pi Over 8 EndFraction radians
b) StartFraction 3 pi Over 4 EndFraction radians
c) StartFraction 7 pi Over 8 EndFraction radians
d) StartFraction 13 pi Over 5 EndFraction radians
Answer:
b) StartFraction 3 pi Over 4 EndFraction radians
Step-by-step explanation:
Minor arc KL measures 135°. Circle O is shown. Line segments K O and O L are radii.
Note that:
π radians = 180°
Therefore,
180° = π radians
135° = x
Cross Multiply
180° × x = 135° × π radians
x = 135° × π radians/180
x = 3π/4 radians
Therefore, the radian measure of central angle KOL is 3π/4 radians. Option b) is the correct option.

Determine the zeros of f(x) = 3x^2 – 10x – 8. (List them in
order from least to greatest, separated by commas. Enter any
fractions as a/b.)
Answer: The zeroes are -2/3 and 4
Step-by-step explanation: The factored form you get from this is (3x+2) and (x-4), set these equal to 0. x-4=0 and 3x+2=0.
The zeroes of the function in the order from least to greatest will be - 2/3 and 4.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
The equation is given below.
f(x) = 3x² – 10x – 8
Then the zeroes of the function are given as,
f(x) = 0
3x² – 10x – 8 = 0
3x² – 12x + 2x – 8 = 0
3x(x – 4) + 2(x – 4) = 0
(x – 4)(3x + 2) = 0
x = 4, - 2/3
The zeroes of the function in the order from least to greatest will be - 2/3 and 4.
