to make $600 she will need to work 40 hours, but she wants to make more than $600 so she needs to work more than 40 hours.. 600/15=40
i hope this helps
Answer:Answer:
f(-2) = 2
f(0) = 3
f (4) = -1
Step-by-step explanation:
The equation of the straight line passing through the points (0,3) and (-4,1) is
⇒ 2(y - 1) = x + 4
⇒ 2y - 2 = x + 4
⇒ 2y = x + 6
⇒
Again, the equation of the line passing through the points (0,1) and (4,-1) is
⇒ - 2 ( y + 1) = x - 4
⇒ - 2y = x - 2
⇒
Therefore, the function is defined as
for x ≤ 0 ........... (1) and
for x > 0 ............ (2)
Therefore, f(-2) = 2 from equation (1).
f(0) = 3 from equation (1)
And f (4) = -1 from equation (2). (Answer)
Step-by-step explanation:
Answer:
A = 15Km/hour B = 0Km/Hour C = 60Km/Hour D = 40/Hour
Step-by-step explanation:
To find speed, the equation is distance / time. So, for a, the distance travelled in 2 hours was 30 Km. To make it a unit number, I divided the 30 / 2 and got 15Km/Hour.
For B, there was no distance travelled. So the velocity would be 0.
For C, the distance travelled in half an hour was 30 Km. So the speed would be 60 Km/ Hour.
For D, the distance travelled in 1.5 hours was 60Km. The distance travelled in 1 hour was 40 Km. So the speed would be 40Km/Hour.
