Assuming that the correct expression is 2(x - 3)= 2(4x -12)
(2 * x) + (2 * −3) = (2 * 4x) + (2 * −12)
2x - 6 = 8x − 24
2x − 6 − 8x = 8x − 24 − 8x
−6x − 6 = −24
−6x − 6 + 6 = −24 + 6
−6x = −18
-6x/-6 = -8/-6

A system of equations is shown:
4c + 2d = 11
(7/2) d = 41 - 220
What is the solution to the system?
C = ?
D = ?
Answer:
c = 793/28 , d = -358/7
Step-by-step explanation:
Solve the following system:
{4 c + 2 d = 11 | (equation 1)
(7 d)/2 = -179 | (equation 2)
Multiply equation 2 by 2:
{4 c + 2 d = 11 | (equation 1)
0 c+7 d = -358 | (equation 2)
Divide equation 2 by 7:
{4 c + 2 d = 11 | (equation 1)
0 c+d = -358/7 | (equation 2)
Subtract 2 × (equation 2) from equation 1:
{4 c+0 d = 793/7 | (equation 1)
0 c+d = -358/7 | (equation 2)
Divide equation 1 by 4:
{c+0 d = 793/28 | (equation 1)
0 c+d = -358/7 | (equation 2)
Collect results:
Answer: {c = 793/28 , d = -358/7

Solve the equation:
5x-2=X+4
Answer: x = 1.5
Step-by-step explanation:
5x - 2 = x + 4
Add 2 to each side
5x = x + 6
Subtract x from each side
4x = 6
Divide each side by 4
x = 1.5
Answer:
x = 3/2
Step-by-step explanation:
5x-2=x+4 (add 2 to both sides)
5x=x+4 + 2
5x=x+6 (subtract x from both sides)
5x - x = 6
4x = 6 (divide both sides by 4)
x = 6/4 = 3/2
which graph represents a function?
Answer:
Graph C) represents a function.
Step-by-step explanation:
Graph C) is the only graph that passes the vertical line test, a way to determine if a graph is a function. All other graphs do not pass the vertical line test. The vertical line test states that if a vertical line drawn intersects the graph of the relation more than once, then the relation is a NOT a function.
The function is indeed a relationship that has only one outcome for each input value (x-value) and output value (y-value). As a result, all functions could be regarded as relationships. However, not all relations are functions because not all of them satisfy the criterion, so each unique input generates just one output.
The third option seems to be the only graph in the present situation that satisfies the vertical line test and determines if a graph is a function. The vertical line test fails on all other graphs. According to the diagonal line test, if a vertical line drawn over the graph of a relation meets it again, the relation is not a function.Therefore, the final answer is "Option C".

(A) after a 5% discount, the price was $190 (B) after a 10% discount, the price was $180 (C) after a 20% discount, the price was $170 (D) after a 30% discount, the price was $140
Answer:
c
Step-by-step explanation:
turn the percent into a decimal and × by the number you get that number that the percent represents in the number add it to the number and you get the original price
The price which is highest is Option C)
After a 20% discount, the price was $170
What is Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Given data ,
A)
After a 5 % discount , the price was $ 190
So , the percentage is calculated as
190 / 0.95 = $ 200
B)
After a 10 % discount , the price was $ 180
So , the percentage is calculated as
180 / 0.90 = $ 200
C)
After a 20 % discount , the price was $ 170
So , the percentage is calculated as
170 / 0.80 = $ 212.50
D)
After a 30 % discount , the price was $ 140
So , the percentage is calculated as
140 / 0.70 = $ 200
Therefore , the price $ 212.50 is the highest
Hence , the solution , after a 20% discount, the price was $170 is the highest

At a competition with 6 runners, 2 medals are awarded for first and second
place
Each medal is different. How many ways are there to award the medals?
Answer:
30 ways
Step-by-step explanation:
The first medal can be awarded in 6 different ways since any of the runners could have it. Once the first medal is awarded, the second medal can only be given to any of the 5 runners available.
So there are 6x5=30 different ways to award the medals
There are 30 ways to award the medals to the winners
How to determine the number of ways?The given parameters are:
Runners = 6
Medals = 2
The first position can be awarded to any of the 6 runners, while the second position can be awarded to any of the remaining 5 runners
So, the number of ways is:
Ways = 6 * 5
Evaluate
Ways = 30
Hence, there are 30 ways to award the medals

Which of the following are equivalent ratios?
A: 12 : 16
B: 3 : 5
C: 2 : 3
D: 6 : 8
The equivalent ratios are A and D.
Here's an explanation:
When you look at D, you see that 12 is a multiple of 6, and 16 is a multiple of 8. So you know that it looks like they're equivalent. Then you test it out, 12/2=6. 16/2=8. so 12:16 = 6:8. Eyeballing it first can save time sometimes.

Write a polynomial function f of least degree that has rational coefficients, a leading coefficient of 1, and the given zeros. -1, 2, 3
Answer:
f(x) = x³ - 4x² + x + 6
Step-by-step explanation:
The polynomial function f has zeros at -1, 2, and 3.
So, the least degree of the polynomial will be 3{As it has three roots}.
Then, if the function is of x variable then (x + 1), (x - 2) and (x - 3) will be the factors of the polynomial.
Therefore, we can write
f(x) = (x + 1)(x - 2)(x - 3)
⇒ f(x) = (x + 1)(x² - 5x + 6)
⇒ f(x) = x³ - 5x² + 6x + x² - 5x + 6
⇒ f(x) = x³ - 4x² + x + 6
Hence, this is the polynomial with least degree having rational coefficients and with leading coefficient of 1 and the zeroes -1, 2, 3. (Answer)
What is the reciprical of 200 and 450
Answer:
Part a) [tex]\frac{1}{200}[/tex]
Part b) [tex]\frac{1}{450}[/tex]
Step-by-step explanation:
we know that
A reciprocal of a rational number [tex]\frac{p}{q}[/tex] is obtained by changing the numerator and denominator, so the numerator becomes the denominator and the denominator becomes the numerator obtaining [tex]\frac{q}{p}[/tex]
Part a) we have
200
we know that
the given number can be expressed as [tex]\frac{200}{1}[/tex]
so
changing the numerator and denominator
The reciprocal is equal to [tex]\frac{1}{200}[/tex]
Part b) we have

Calculator
Answer:
The value of car decreases by 12% each year.
Step-by-step explanation:
A car dealership creates an expression to model the value of a new car t years after it is purchased and the expression is [tex]P(0.88)^{t}[/tex] ..... (1)
Now, if the value of the car depreciates at a rate of r% each year, then the value of the car (Say, P) will be depreciated to the value
[tex]P' = P(1 - \frac{r}{100} )^{t}[/tex] ...... (2)
Now, comparing the expressions in (1) and (2), we get
[tex]1 - \frac{r}{100} = 0.88[/tex]
⇒ [tex]\frac{r}{100} = 0.12[/tex]
⇒ r = 12%.
Therefore, the value of the car decreases by 12% each year. (Answer)

Step-by-step explanation:
The question is
Find the measure of angle y
step 1
Find the measure of angle x
see the attached figure to better understand the problem
we know that
m∠x=67° -----> by corresponding angles
step 2
Find the measure of angle y
we know that
(m∠x+m∠y)+42°=180° -----> because form a straight line
substitute the measure of angle x
67°+m∠y+42°=180
m∠y+108°=180
m∠y=180°-108°
m∠y=72°
What is the y and c intercepts of the linear equation
4.) y=-5x+10
Answer:
x-intercept is 2, y-intercept is 10.
Step-by-step explanation:
y=-5x+10
y=mx+b
-------------
m=-5 which means that the slope of this equation is -5.
And to find the y-intercept,
plug in x=0 into the equation and find out the value of y.
y=-5(0)+10=0+10=10
So the y-intercept is 10.
And to find the x-intercept,
plug in y=0 into the equation and find out the value of x.
0=-5x+10
-5x=0-10
-5x=-10
5x=10
x=10/5=2
So the x-intercept is 2.

Keegan rides the bus 4 miles to school in the morning, and 4 miles home from. school in the afternoon. How many miles does Keegan ride the bus in 5 days?
Final answer:
Keegan rides 8 miles per day going to and from school. Over the course of 5 days, he rides a total of 40 miles on the bus.
Explanation:
The question asks how many miles Keegan rides the bus in 5 days if he travels 4 miles to school and 4 miles home each day. To solve this, we can multiply the daily round trip distance by the number of school days in a week. Keegan travels 8 miles per day (4 miles to school and 4 miles back home). So, in 5 days, Keegan will have traveled:
8 miles/day imes 5 days = 40 miles
Therefore, Keegan rides the bus 40 miles in 5 days.
