What is the degree of this polynomial 15x^5z^2-7y

Mathematics

That polynomial is made up of 2 terms, 15 x^{5}z ^{2} and 7y, separated by a minus sign.  To find the degree of a polynomial you consider the term with the highest degree, no matter that the variables are different.  The degree on the first term is 5+2=7, whereas the degree on the second term is just 1.  Since the degree of a polynomial is equal to the degree of the term that is highest, our degree is 7.

Steve can jog 14 miles in 2 hours. At this rate, how many miles can he jog in 1/4 hour?
Assoli18 [71]

Answer:

1  3/4 miles in 1/4 hour.

Step-by-step explanation:

Write and solve an equation of ratios:

 x           (1/4) hr

--------- = ------------

14 mi       2 hr

Cross multiplying, we get 2x = (1/4)(14), or

                                              x = (1/4)(7), or x = 7/4

Steve can jog 7/4 miles in 1/4 hour.  That's 1  3/4 miles in 1/4 hour.

9.1 times 11.8 estimate the product by rounding each decimal number to the nearest whole number
lutik1710 [3]
We will round both numbers:-

9.1 = 9 

11.8 = 12

Now we will multiply these 2 numbers to get our answer. 

9 × 12 = 108

So, 9.1 ÷ 11.8 is ABOUT 108.

Hope I helped ya!!!!!!!

Write the equation in slope intercept form of a line that goes through (4,9) and has a slope of 1/2
Vedmedyk [2.9K]

Answer:

y = \frac{1}{2} x + 7

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

here m = \frac{1}{2}, hence

y = \frac{1}{2} x + c ← is the partial equation

to find c substitute (4, 9) into the partial equation

9 = 2 + c ⇒ c = 9 - 2 = 7

y = \frac{1}{2} x + 7 ← equation in slope-intercept form
