Question

Questions i nee help with:

#24 What is the steepest slope?

a) -8 b) -1/15 c) 9/10 d) 5

#26 Whih Function has a y intercept f 5?

A) y= -5x+1 B) 5y=x+1 C) y= 5x+1 D) y-5=x

#34 Classify x^3-8 according to its degree and number of terms?

Please Explan

Answer 1

b (slope = rise over run) this means that for the whole numbers the rise is that whole number and the run is one. You are looking for the numbers where the top of the fraction has the biggest difference from the bottom of the fraction as possible. For a the difference between them is -7 because(-8 - 1) . For b the difference is 16. the difference in c is only one and the difference in d is four.

d rearrange and you will see y= x + 5

the equation for a function is y=mx + b

m is the slope and b is the y-intercept

degree = 5 number of terms = 1

simplify the exponent 3-8 equals -5

take the absolute value and that is the degree

the number of terms in other words is the number of variables.

the only variable in the equation is x meaning that there is only one term

EDIT... i misread #34 the degree is three because it is the highest number that a variable is raised to

it is a cubic binomial because cubic refers to the power to which the exponent is raised and  binomial means that the there are two pieces to the equation... x^3 and -8

Answer 2

24

   A ( because 8 over 1 is 8 up and over 1, and D would be the second most steep with a rise of 5 and a run of 1, C would be the 3rd steepest and B is almost a flat line)

#26

   A ( i think because when you divide the signs switch.. and in in B it would cancel out and C would make it negative 5 and D is just Y)

#34

  im not sure sorry

Answer 3

A

D

and I dont understand the question

Answer 4

24. The steepest slope is the slope with the greatest positive number.

26. to find the y-int put 0 (zero) in for x and solve for y. If y = 5 that is your answer. Try it. You should get choice D

bye for now.

Answer 5

for #24 - slope is usually rise/run or y/x. The largest slope will therefore be the largest absolute value, so A.

#26 - make x=0 for this one and solve for y. The correct answer is where y=5. The correct answer is D.

#34 - the highest order term is to the 3rd power, so the  equation is "cubic". The number of terms is 2 because... well, there are two components to the equation, so it is a binomial. so... cubic binomial.
