The rational root are x= 7,-3,-6
You can find them by substituting y for 0
Answer:
#7 = 430
#9 = 16
#11 = 930
Step-by-step explanation:
7 to the power of 2 is 49 / 49+3 is 52 / 52-9 is 43 / 43x10 is 430
66 divided by 11 is 5 / 5 +3 is 8 / 8 X2 is 16
18 -3 is 15 / 15 + 3 is 18 / 18 to the power of 2 is 324 / 324 - 14 is 310
310x3 is 930
They would meet 30 times after 10 minutes.
Since Nick and Sally run on the 100m straight track, and Nicks's speed is 3m / s, while Sally's speed is 2m / s, if they both start from two sides of the track, running towards each other continuously, to determine how many times they would meet each other after 10 minutes the following calculation should be performed:
- 30 x 20 + 2 x 20 = 60 + 40 = 100
- 10 minutes = 600 seconds
- 600/20 = X
- 30 = X
Therefore, they would meet 30 times after 10 minutes.

Answer:
y = x - 1
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 )
y = - x - 1 ← is in slope- intercept form
with slope m = - 1
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= 1, thus
y = x + c ← is the partial equation of the perpendicular line
To find c substitute (- 1, - 2) into the partial equation
- 2 = - 1 + c ⇒ c = - 2 + 1 = - 1
y = x - 1 ← equation of perpendicular line
Answer:
7
Step-by-step explanation:
56 times (1/2)=28
Again times (1/2)=14
Last one times (1/2)=7
C(1)=56
C(2)=28
C(3)=14
C(4)=7
