Which is the slope of the line that passes through the points (3, 1) and (-2, 5) A: 5/4
B: -5/4
C: 4/5
D: -4/5
Which is the slope of the line that passes through - 1

Answers

Answer 1
Answer: slope=(y2-y1)/(x2-x1)
(x,y)
(3,1)
(-2,5)
x1=3
y1=1
x2=-2
y2=5

slope=(5-1)/(-2-3)=4/-5=-4/5
slope=-4/5

answer is B

Step-by-step explanation:

the unknown can NEVER be negative

so you wont see an answer like

-b= 7, -a=98; -k= -9

so,

-x= -8 (change their positions so that the unknown, x, is positive)

x=8

Q: At noon the armadillo left the wild kingdom and headed north at 3 kilometers per hour . two hours later the raccoon left the same kingdom and headed south at 5 kilometers per hour . at what time will the animalse be 38 kilometera apart ?

Answers

Distance of armadillo = V * t = 3t
Distance of racoon = V * (t-2) =5*(t-2)
Distance of armadillo + distance of racoon = 38
3t + 5(t-2)=38
3t + t5 - 10 =38
8t=48
t=6
The anwser is: they will be 38 km apart after 6 hours, so it is 6p.m (12a.m+6 hours)

Which of the following is the function representing the graph below?

Answers


You need to pick a point on the graph, then go through the list of choices
and see which one can produce the point you picked.

Look at the point on the graph right above the origin, where the graph
crosses the y-axis.  At that point, x=0 and f(x) (or 'y') = 1 .

Now look at the choices, one at a time, and see whether  (0, 1)  fits.
I'll start at the bottom of the list:

-->  f(x) = 4^(x-3)
When x=0, f(x) = 4^(-3) .
4^(-3) is not '1', so our point is not on this f(x).

-->  f(x) = 4^x + 3
When x=0, f(x) = 4⁰ + 3  =  1 + 3  =  4
'4' is not '1', so our point is not on this f(x).

-->  f(x) = 4^x - 3
When x=0, f(x) = 4⁰ - 3  =  1 - 3  =  -2
'-2' is not '1', so our point is not on this f(x).

(Only one choice left.)

--> f(x) = 4^x
When x=0, 4^x = 4⁰  =  1
That's it !  Our point is on this f(x).
Which is lucky, because we were out of choices.

What is the average of 30, 40, and 80?

Answers

Because 80+40+30 equals 150 then you divide by how many number there are and there are 3 so 150 divided by 3 = 50
40x80=3200
3200/2=1600
So the answer is 1600
