Steven has some money. If he spends $9.00, then he will have 3/5 of the amount he started with​
ELEN [110]

Answer:

m - 9 = 3/5 m (Steve has some money. After spending $9, he now has 3/5 of his original amount)

So it's just the matter of isolating m. Subtract m from both sides:

-9 = -2/5 m

Now you just need to multiply both sides by -5/2 to get your final answer.

I did something wrong could you help?
posledela

Answer:

Slope = 1/2

y-intercept = 30

Equation : y = 1/2x + 30

D. 150 miles

Step-by-step explanation:

We can use the two visible points you marked on the graph.

They are (0,30) which is also the y-intercept and (20,40).

Calculate change of y over change of x.

10/20 or 1/2

So the slope is 1/2 and the y-intercept is 30.

Therefore, using y = mx + b form, the equation is y = 1/2x + 30

Then, to find how many miles you drove if the cost was $105, we can plug in 105 for y in the equation.

105 = 1/2x + 30

75 = 1/2x

x = 150
