Answer:
[tex]\displaystyle y=8x[/tex]
Step-by-step explanation:
We are given a table and we want to determine a linear equation (in slope-intercept form) that represents this table.
So, we will first need to determine the slope. We can use the slope formula:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Where (x₁, y₁) and (x₂, y₂) are two points.
We have three points: (1, 8), (2, 16), and (3, 24).
Let’s pick two. We can use (1, 8) and (2, 16).
So, let (1, 8) be (x₁, y₁) and let (2, 16) be (x₂, y₂). Substitute appropriately:
[tex]\displaystyle m=\frac{16-8}{2-1}[/tex]
Evaluate:
[tex]\displaystyle m=\frac{8}{1}=8[/tex]
So, our slope is 8.
Now, we can determine the equation using point-slope form:
[tex]\displaystyle y-y_1=m(x-x_1)[/tex]
Where m is our slope and (x₁, y₁) is a point.
We know that the slope is 8, so we will substitute 8 for m.
We can use any of our three points for the point. Let’s use (1, 8) for consistency. So, let (1, 8) be (x₁, y₁). Substitute appropriately:
[tex]\displaystyle y-8=8(x-1)[/tex]
Solve for y. Distribute the right:
[tex]\displaystyle y-8=8x-8[/tex]
Add 8 to both sides:
[tex]\displaystyle y=8x[/tex]
And we have our equation.
Notice that this is a direct variation or proportional equation as we don’t have a y-intercept.
Solve the equation. Show your work in the space provided. 2X - 0.5 = 3.7

1. Erik buys carrots and dip for a class snack. The carrots are $3.80, and the dip is $2.60. Erik has a coupon for 5% off his groceries. He does not need to pay tax. He gives the cashier $20. How much change does he receive back?
2. Liam buys a new TV that cost $360. The TV is on sale for 40% off, and the store is offering an additional 20% off all sale items. How much does Liam save on the TV?
Answer:
1. $3.80 + 2.60=$6.40 *.05=$5.08
$20.00-$5.08=$14.92
2. $360 x %40=$14,000
$14,000/100=144 360-144 = 216
$216 x %20 = $4,320/$100= $43.20
$216-43.20= $172.8
$360-$172.80=$187.20

Daniel buys a video game for $48.50. He must pay 6% sales tax. How much tax must Daniel pay?
he would pay 51.41
take 48.50 times by .06 (tax)
you would get 2.91
add 48.50 + 2.91 which equals 51.41
Answer:
$51.41
Step-by-step explanation:
48.50 x .06 2.91 then, add 48.50 + 2.91 which equals 51.41.

5x + 2 = 3x + 4(2x - 1) please solve step by step
Answer:
x=1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5x+2=3x+4(2x−1)
5x+2=3x+(4)(2x)+(4)(−1)(Distribute)
5x+2=3x+8x+−4
5x+2=(3x+8x)+(−4)(Combine Like Terms)
5x+2=11x+−4
5x+2=11x−4
Step 2: Subtract 11x from both sides.
5x+2−11x=11x−4−11x
−6x+2=−4
Step 3: Subtract 2 from both sides.
−6x+2−2=−4−2
−6x=−6
Step 4: Divide both sides by -6.
−6x
−6
=
−6

9+3=12
What does Point P on the number line represent? (Use the hyphen for negative numbers, such as –9)
Number line from negative 12 to positive 12 in increments of 1 is shown. Only the even numbers are labeled. A point labeled P is placed at the first tick mark to the left of negative 10.
(1 point)
Answer:
A number line is used in the mathematical positioning of real numbers that include the numbers from positive infinity to negative infinity. This includes rational, irrational, fractions, and whole numbers. In this case, we are given with an expression that we have to reduce to lowest terms: negative seven and one over two and +1. The first one is equal to -7.5 while the other one is equal to +1. Positive numbers lie on the right side of zero (center of the line) while negative numbers lie on the left on the other hand. -7.5 lies between -8 and -7 while +1 lies exactly between 0 and 2. Both of which are positive numbers

I just need someone to take help me with the last set of measurements!!
You will need to measure five different people. Record your measurements on the table below. Using a tape measure or ruler, measure the length (in inches) of a person’s left foot and then measure the length (in inches) of that same person’s forearm (between their wrist and elbow). Refer to the diagrams below. You will have two measurements for each person.
(An easy way to measure the length of a foot is to have your subject stand on a piece of paper. Then, trace their foot and measure the outline once they move off the paper.)
To measure the forearm, measure inside the arm, between the wrist and the elbow
Answer:
Im not quite sure what your asking, but i'm doing this assignment rn. the mesurments i got and am using are
13 forearm and 15 left foot
9 1/2 forearm and 9 left foot
8 forearm and 8 1/2 left foot
9 1/2 forearm and 10 1/2 left foot
10 forearm and 8 left foot
Step-by-step explanation:

A cell phone costs $120. The price is reduced 30% for a sale. How much is the savings?
Answer:
the phone is 84 dollalrs
Step-by-step explanation:
Answer:
$36
Step-by-step explanation:
Since 30% = 30/100 then we can transform it into a decimal:
30%=0.30
Now if we multiply 120•0.30, we will get how much we saved.
$36, we saved $36.
Bonus information:
If the problem was to say "How much does the cell phone cost after the discount?", then you would multiply 120•0.70.
