Answer:
y = x+40
Step-by-step explanation:
First, calculate the rate of the rate by using the slope formula, [tex]m = \frac{y_1-y_2}{x_1-x_2}[/tex].
m = (50-47)/(10-7) = 3/3 = 1
Now plug m = 1 into the slope-intercept form, y = mx+b. Also plugin y = 42 and x = 2 in other to find the y-intercept (b).
42 = 1(2)+b
42-2 = b
b = 40
Replace b with 40 in the slope-intercept formula.
y = x+40

What is the range of the function f(x) = 2x + 4 when the domain is {-2, 0, 3}?
Answers
Answer: range = {0, 4, 10}
Step-by-step explanation:
Range means y which means f(x)
so we just have to plug in the domains(x) into the equation one at a time
f(-2) = 2(-2) + 4 = 0
f(0) = 2(0) + 4 = 4
f(3) = 2(3) + 4 = 10
those would be the range.. hope I was fast enough haha

You win an online auction for a toy. Your winning bid of $90 is 75% of your maximum bid. How much more were you willing to pay for the toy than you actually paid?
Answers
Let your bid = b
b * 0.75 = 90
Divide by 0.75
90/0.75 = 120
Check:
120 * 0.75 = 90 :)
I could have paid $30 more dollars for the toy than I actually paid.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, You win an online auction for a toy and your winning bid of $90 is 75% of your maximum bid.
Assuming 'x' is the maximum amount I could have paid for the bid.
Therefore, 75% of 'x' is $90 which is,
(75/100)×x = 90.
0.75x = 90.
x = 90/0.75.
x = 120.
So, The amount of more money I could have actually paid is,
(120 - 90)
= $30.

you go into best buy to purchase a new TV and bring 500 with you.The TV cost 466 and there is a 7% sales tax. how much will u have left after you leave best buy
Answers
Answer:
1.38
Step-by-step explanation:
The total cost of the TV is the retail price plus the tax, tax (in this case) is 7% or 0.07 of the retail price, so
T = p + 0.07p, at a price of 466
T = 466 + 0.07(466)
t = 466 + 32.62 = 498.62
If you arrived with 500, you'd leave with 500 - 498.62 = 1.38 and a TV
