Think of it this way: from -8 to 0 and then from 0 to 14 (degrees F).
+8 + +14
this works out to +22 degrees F.

Firlakuza [10]

Answer:

4.73%

Step-by-step explanation:

y = 3×2^(t/15) = 3×(2^(1/15))^t = 3×1.0472941^t

In this form, ...

1 +r = 1.0472941

r = .0472941 ≈ 4.73%

The daily increase is about 4.73%.

Answer:

(-8,4)

Step-by-step explanation:

System of Equations:

Solve the following system of equations by the substitution method:

5x - 6y = -64 [1]

y = 20 + 2x [2]

Substituting y from [2] in [1]:

5x - 6(20 + 2x) = -64

Operating:

5x - 120 - 12x = -64

Simplifying:

-7x - 120 = -64

Adding 120:

-7x = -64 + 120 = 56

x = 56/(-7) = -8

x = -8

From [2]:

y = 20 + 2(-8) = 4

Solution (-8,4)

3x*5x*8x=960
x^3=960/120
x= cubrt(8)=2
sides then are 6;10;16

Can you please show me how you got the answer (50 points)

Answer:

$4x^{6}2y^{-2}$

Step-by-step explanation:

We can use a property I like to call SEi-F. (Subtract Exponents in a Fraction)

But first, there is an exponent outside of the parentheses in both places. We can use the Power of Parentheses to simplify and then use the SEi-F.

We will start with the x in the numerator.

3*4 = 12

Now for the y in the numerator.

4*4 = 16

Our new numerator is $4(2x^{12}y^{16})$

We do need to simplify the numerator one more time to get rid of the 4 outside the parentheses.

We will start with x's coefficient.

2*4 = 8

Now for y's coefficient.

1**4 = 4

*y seems to have no coefficient, but if so, it has a coefficient of 1. This applies to other variables.

Our final simplified numerator is $8x^{12}4y^{16}$ .

Repeat with the denominator.

Try it yourself!

Make sure that when you finish, you finish the fraction.

After completing the denominator, your completed fraction should be:

$\frac{8x^{12}4y^{16}}{4x^{6}2y^{18}}$

Now we can use the SEi-F to complete the problem.

Start with x.

8x - 4x = 4x

12 - 6 = 6

The first term is $4x^{6}$ .

Now for y.

4y - 2y = 2y

16 - 18 = -2

The second term is $2y^{-2}$

The complete, simplified equation is $4x^{6}2y^{-2}$ .

I could be wrong on the answer, but the work should be correct.

Hope this helps. Have a nice day. Oh, and one more thing. Surprised I'm not stealing points?
