Distance traveled in 35 minute = 2 miles.

So distance traveled in one minute = 2/35 (miles/minute)
                                                             = 0.0572 miles / minute.

So distance traveled in one hour  , we can find by multiplying it from 60.Because in one hour there is 60 minute.

SO distance traveled in one hour = 0.0572 * 60 
                                                          = 3.432 miles / hour.

What are the zeros of y=x^2 +2x -8
Igoryamba
Y = x² + 2x - 8

which two numbers add up to 2 and multiply to -8?

-2 and 4

so rewrite the expression using the above;

(x - 2)(x + 4)
x = 2, -4

so the zeros are 2 and -4.

hope this helps, God bless!

What must be added to x - y to obtain y-x?
Lera25 [3.4K]
To make x-y reasonable, you must make x the same value as y. It is the same as y-x. But a different variable order. For example x= 6 and y=9, and x - y is unreasonable, to make it reasonable, you must add 3 more to x to make it the way of y - x. So, your answer is just like 9-9 or 10-10 or any other subtraction equation with equal value, you don’t have to know what the variables equal, you just have to take an example and try it, that’s all you need to do to get out of the tricky problems. Hope this helps and have a great night of sleep :))

Will mark Brainliest!!!!! Suppose A, R, and B are collinear on AB, and
SSSSS [86.1K]

Answer:

R(x,y) = (\frac{7}{4},\frac{1}{4})

Step-by-step explanation:

Given

A = (1,-1)

B = (4,4)

AR:AB = 1:4

Required

Determine R

This question will be solved using line ratio formula

R(x,y) = (\frac{mx_2 + nx_1}{m+n},\frac{my_2+ny_1}{m + n})

Where

A = (1,-1)

B = (4,4)

m:n = AR : RB

Since R is on A and B;

AB = AR + RB

4 = 1 + RB

RB = 3

Hence;

m:n = 1 : 3

A = (1,-1)

B = (4,4)

R(x,y) = (\frac{mx_2 + nx_1}{m+n},\frac{my_2+ny_1}{m + n}) becomes

R(x,y) = (\frac{1 * 4 + 3 * 1}{1+3},\frac{1 * 4 + 3 * -1}{1 + 3})

R(x,y) = (\frac{4 + 3}{4},\frac{4 - 3}{4})

R(x,y) = (\frac{7}{4},\frac{1}{4})
