Just do it!

yo guest you better stop or yu'll gonna pay 

a brand of cheese is sold in 340g packages for 3.79 and 600g package for 5.29 calculate the unit price per gram for each package size 

3.79/340=0.01114 cents? per gram

5.29/600=0.008817 cents? per gram

Solve for z:
11 z+11.6 = 14 z-3.4

11 z+11.6 = 11 z+58/5 and 14 z-3.4 = 14 z-17/5:
11 z+58/5 = 14 z-17/5

Subtract 14 z+58/5 from both sides:
-3 z = -15

Divide both sides by -3:
Answer: |  z=5
 

shut up guest you lil dork

Hello

Thank you :D

2nd  acos  number

0 is not a fraction and therefore is a whole number

Mr.Thompson is on a diet. He currently weighs 260 pounds. He loses 4 pounds per month. After how many months will Mr. Thompson reach his goal weight of 220 pounds? in standard form and slope intercept form

x = month

slope intercept form: \(y= 260-4x\)

standard form: \(4x + y= 260\)

\(\begin{array}{rcl} 220 &=& 260 - 4x \\ 4x &=& 260-220\\ 4x &=& 40 \qquad | :4 \\ x &=& \frac{40}{4} \\ \mathbf{x} & \mathbf{=} & \mathbf{10} \end{array}\)

Mr. Thompson reach his goal weight of 220 in 10 month

0.4^log0.4(10).

\(x^{log_xy} =y\)

 so      \(0.4^{log_{0.4}(10)}=10\)

There is no question here. :/

Yes, unless you are told you have to use a particular method you are free to choose :)

y= -2x^2 + 5

It is a parabola because of the x^2   (The degree of trhe polynomial is 2)

And it is concave down because the number in front of the x^2 ( the leading coefficient) is negative.

The vertex is (0,5)

2x^2+16x+26=0

Just use the quadratic formula

Find sin t and cos t for the given value of t.

t = 945°

945-360-360=225

225-180=45

so  

945 is equivalent to 225 degrees which is in the 3rd quadrant and the equivalent acute angle is 45 degrees.

Sin and cos are both negative in  the 3rd quadrant.

\(sin(945)=cos(945)= - cos(45) =-sin(45)=\frac{-1}{\sqrt2}\)

log3(x) = 5

\(If\;\;log_3(x) = 5\\ then\\ x=3^5\\ x=243\\~\\or\\~\\ log_3(x) = 5\\ 3^{log_3(x)} =3^ 5\\ x=243\)

what is x in  log3(x) = 5

x=log(5)/log(3)

x=1.465, so that,

3^1.465=5

Solve for x:
x^3-7 x+6 = 0

The left hand side factors into a product with three terms:
(x-2) (x-1) (x+3) = 0

Split into three equations:
x-2 = 0 or x-1 = 0 or x+3 = 0

Add 2 to both sides:
x = 2 or x-1 = 0 or x+3 = 0

Add 1 to both sides:
x = 2 or x = 1 or x+3 = 0

Subtract 3 from both sides:
Answer: | x = 2    or x = 1    or x = -3
