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

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

a. (2,-2/3)
b. (3,-3/2)
c. (3,-2)
d. (2,2)
please explain how you got your answer.
Answer:
b
Step-by-step explanation:
[tex]3x - 2y = 12 \\ 2x + 2y = 3 \\ 2y = 3 - 2x \\ 3x - (3 - 2x) = 12 \\ 3x - 3 + 2x = 12 \\ 5x = 15 \\ x = 3 \\ 2y = 3 - 6 = - 3 \\ y = - \frac{3}{2} [/tex]
(3, -3/2)

Which function is a quadratic function? u(x) = –x + 3x2 – 8 v(x) = 2x2 + 8x3 + 9x y(x) = x2 + 3x5 + 4 z(x) = 7x2 + 2x3 – 3
Answer:
u(x) = –x + 3x2 – 8
Step-by-step explanation:
The functions are;
u(x) = –x + 3x2 – 8
v(x) = 2x2 + 8x3 + 9x
y(x) = x2 + 3x5 + 4
z(x) = 7x2 + 2x3 – 3
A quadratic function is a function that has the form f(x) = ax2 + bx + c where a, band c are numbers with a not equal to zero. The maximum degree must be 2.
Among all the options, the one that matches the form is;
u(x) = –x + 3x2 – 8
Answer:
u(x)=-x+3x2-8

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 :)
Solve for f
0.3=0.5f-0.7
Answer:
f=2
Step-by-step explanation:
0.3+0.5f-0.7
Move the varibale (0.5f) to the left-hand side and change it's sign to negative.
-0.5+0.3+-0.7
Move the constant to the right hand side and change it's sign
-0.5f=-0.7-0.3
Calulate the differnce
-0.5f=-1
divide both sides by -0.5
F=2

the temperature was -4.f this morning. if the temperature dropped 7.f, what is the temperature now
Answer:
The temperature now is - 11.f
Step-by-step explanation:
If it was - 4.f and now it is 7.f colder, so then all we have to do is subtract 7.f from -4.f and get...
-4.f - 7f. = - 11.f
Therefore the current temperature is - 11.f

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
