Answer:
10.3 m/s
Step-by-step explanation:
Speed = Distance / Time
100 metres travelled in 9.7 seconds means that her speed was 100/9.7 metres per second, which is 10.30927... rounded to 10.3 metres per second.
Answer:
option d
Step-by-step explanation:
-5x + 4 - 7 + 8x =
-1(3x - 3)
-3x+3=
So,
Let's manipulate this into the y=mx + b form.
Add 4x to both sides
-6y = 4x + 24
Divide both sides by -6
Just use the slope to find the points you need.
The y-intercept is
(0,-4).The slope is
. Finding the next point:
(-6,0)You could have also used the <em>slope intercept method.</em>
-4(0) - 6y = 24
-6y = 24
Divide both sides by -6
y = -4
(0,-4)-4x - 6(0) = 24
-4x = 24
Divide both sides by -4
x = -6
(-6,0)
The magnitude of a real number without regard to its sign.
