Answer:
No solution.
Step-by-step explanation:
Let us approach this question geometrically . Number of solutions is the number of meeting points of the two graphs . We can see that the given equations are equations of lines . First equation is 5x - y = 3.
Second equation when divided by two can be written as 5x - y = -1.
We can see that these lines are parallel and therefore doesn't intersect.So no solution.
Answer:
A
Step-by-step explanation:
It would be A,
As we can see, p*c =60 for every value in the chart. We can rearrage this to get c=60/p

Answer is -7/2
Gradient or slope is found by change in y over change in x.
Or
(y2 - y1) over (x2 - x1)
So
(-2 -5) over (4-2)
= -7/2
It would be 7 hours because 35 x 3 is 105, if she is already 105 miles from home then 35 x 7 is 245. 245 + 105 = 350. Candice would be at 350 and Liz would be at 350, so in conclusion the answer is 7 hours. :)
