In Exercises 26-28, write an equation. Then solve.

Answer:

The temperature outside is 75.6°F

Step-by-step explanation:

We are given the following in the question:

The temperature of dry ice = - 109.3°F

Let x be the temperature outside in Fahrenheit.

It is given that the temperature of dry ice is 184.9°F less than the outside temperature.

Thus, we can write the equation:

$x - 184.9 = -109.3$

Solving, the above equation, we get:

$x - 184.9 = -109.3\\x = -109.3 + 184.9\\x = 75.6$

Thus, the temperature outside is 75.6°F

Find the rate of change in the table

mixas84 [53]

Answer:

I'm pretty sure it's +(-6).

Step-by-step explanation:

Basically for these, you find the slope. The slope equation is y1-y2/x1-x2.

Pick two points.

I'll just do (1,15) and (2,9).

15-9/1-2 = 6/-1 = -6.

I don't know if you were taught it this way, but my math teacher always told us that the rate of change had to be positive.

So you'd say the rate of change is +(-6), not -6.

Hope that sorta helped lol

Michael is buying a pair of jeans that regularly cost $40. They are on sale for 20% off. If the tax rate is 8%, what is the sale

Anna35 [415]

Answer

Find out the what is the sale price of the jeans including tax .

To prove

Let us assume that the sale price of the jeans including tax be x .

As given

Michael is buying a pair of jeans that regularly cost $40.

They are on sale for 20% off.

If the tax rate is 8% .

20% is written in the decimal form

$= \frac{20}{100}$

= 0.20

8% is written in the decimal form

$= \frac{8}{100}$

= 0.08

Than the equation becomes

x = 40 - 40 × 0.20 + 40 × 0.08

x = 40 - 8 + 3.2

x = 43.2 - 8

x = $35.2

Therefore the sale price of the jeans including tax be $ 35.2 .

Arrange the following polynomial into descending order for x, then interpret the degree of the 3rd term. 2xy4 + 2x2y − 3y2 + 10x

malfutka [58]

To arrange the given polynomial in descending order of x, we only look at the exponent of x in each term and then write it in decreasing order of the value. We do as follows:

2xy^4 + 2x^2y − 3y^2 + 10x^3<span>
10x^3 + 2x^2 + 2xy^4 - 3y^2

The degree of the third term would be 5. The degree of a term is the sum of the exponents of the variables involved in the term.
