Answer:
x = 0
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2(x+7)=−4x+14
(2)(x)+(2)(7)=−4x+14(Distribute)
2x+14=−4x+14
Step 2: Add 4x to both sides.
2x+14+4x=−4x+14+4x
6x+14=14
Step 3: Subtract 14 from both sides.
6x+14−14=14−14
6x=0
Step 4: Divide both sides by 6.
6x 0
6 = 6
x=0

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
Expand & simplify
(2x + 6)2
Answer: 4x+12
Step-by-step explanation:
The distributive property states that a(b+c) = ab+ac.
Thus, simply do 2*2x+2*6 = 4x+12

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?
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.

What is the range of the function f(x) = 2x + 4 when the domain is {-2, 0, 3}?
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

Answer:
The original price was $90.
Step-by-step explanation:
Let j represent the original price. Then, subtract 20% from 100%, obtaining 80%. The markdown price is 80% of j, or 0.80j = $72
Solving for j, we get j = $72/0.80 = $90

Camille's birthday party will cost $32 if she invites 16 guests. How many guests can there be, at most, if Camille can afford to spend a total of $48 on her birthday party? Assume the relationship is directly proportional.
Answer:
I think its gon be 24 guests
Answer:
24 people can be there at most :)
Step-by-step explanation:
$32 divided by 16(guests) is $2
so its $2 per person
so 48$ divided by $2 is 24
So Camille can invite 24 people at the cost of 48$ being her total at most :)

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
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

If the perimeter of a rectangle is 360 feet, and the length is twice the width, what is the length?
Answer:
(P) =360
(l) =?
(b) =?
so, let the breadth be x
let the length be 2x
Perimeter of rectangle=2(l+b)
360 =2(2x+x)
360/2 =2x
180/2 =x
60 =x
x =60
ATQ
Breadth = 60
length= 60 ×2
=180
