It takes me 12 minutes to run 2 kilometers. How long will it take me to run 10,000 meters?
galina1969 [7]
60min or 1 hour

Because 2km is equal to 2000m
Therefore you multiply 12 min by 5 (because 2000m x 5 is 10000m)

Parallelogram H G J L is shown. Diagonals are drawn from point H to point J and from point G to point L and intersect and point
Ghella [55]

Answer:

50 units.

Step-by-step explanation:

It is given that HGJL is a parallelogram and diagonals intersect each other at point K.

HK=c-7,JK=3c-33,GK=c+12

We now that diagonals of parallelogram bisect each other. So,

HK=JK

c-7=3c-33

33-7=3c-c

26=2c

Divide both sides by 2.

13=c

Now,

GK=c+12=13+12=25

Diagonals of parallelogram bisect each other. So,

GL=2(GK)=2(25)=50

Therefore, the measure of GL is 50 units.

A polynomial function can be written as (x - 1)(x - 4)(x + 7). What are the x-intercepts of the graph of this function?
bekas [8.4K]

X - intercepts are also known as zeros. To solve this simply take each factor of the polynomial and set it equal to zero. Solve for x then you'll have your x - value of the x intercept.

x - 1 = 0

x - 1 +1 = 0 + 1

x = 1

x - 4 = 0

x - 4 + 4 =0 +4

x = 4

x + 7 = 0

x + 7 - 7 = 0 - 7

x = -7

^^^All the above are the x values of the x - intercepts

The answer is...

C. (1 , 0) (4, 0) ( -7, 0)

Hope this helped!
