What does x equal ???? Help please

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

P = 2(a+b)

a = side

b = base

The perimeter of the parallelogram is [tex]\sqrt[2]{29}+ \sqrt[6]{6}[/tex]

Since the coordinates are  (2,10), (4,2), (7,8) and (-1,4).​

Now for determining the perimeter first we have to calculate the distance of AB and BC

So,

For AB, the distance is

[tex]= \sqrt{(2-7)^2 + (10-8)^2}\\\\ = \sqrt{29}[/tex]

Now

For BC, the distance is

[tex]= \sqrt{4-7)^2 + (2-8)^2}\\\\ = \sqrt{54}\\\\= 3\sqrt{6}[/tex]

Now the perimeter is

= 2(AB + BC)

= [tex]2(\sqrt29 + 3\sqrt 6)[/tex]

= [tex]\sqrt[2]{29}+ \sqrt[6]{6}[/tex]

Therefore, The perimeter of the parallelogram is [tex]\sqrt[2]{29}+ \sqrt[6]{6}[/tex]

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)

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

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

Step-by-step explanation:

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 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

Step-by-step explanation:

Answer:

a = 4

Step-by-step explanation:

So your goal here is to get the variable on just one side, so add 4a to both sides.  This cancels out the 4a on of of the sides and puts a on the other side.  The new equation is 8 = -2a + 4a.  Combine like terms to get 8 = 2a.  Divide both sides by 2 to get a = 4.    You can check your work by replacing a with 4:  

8 - 4(4) = -2(4)

8 - 16 = -8

-8 = -8

Since the final result is true, (-8 does equal -8,) a = 4.  

Answer:

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
