Jeremy rode his bicycle in a race. He averaged 15 mph and began the race 1 hour ahead of the other riders. The variable d repres

ents Jeremy's distance ridden, in miles. The variable t represents the number of hours since the other riders began to race. Which equation can be used to determine the distance Jeremy rode t hours into the race?
d = 15t + 1

d=15(t+1)

d=15(t−1)

d=15t−1

Answer:

d=15(t+1)

Step-by-step explanation:

The 15 represents Jeremy's speed, which is 15 miles per hour.

The (t+1) represents the total number of hours Jeremy rode his bike, including the 1 hour head start he got.  This adds his head start (1) and the rest of the time he has ridden (t).

As mentioned in the problem, d represents the total distance in miles that Jeremy rode on his bike.

D = 15(t + 1)

Explanation:
It would be t + 1 rather than t - 1 because he has one *more* hour compared to the other riders.
The reason why t + 1 is in parentheses is because when solving, you'd have to first add instead of multiply.

Slope of 2 and passes through the point (-4,3). Write the equation in slope intercept form
erastova [34]

Answer:

The equation is y = 2x + 11.

Step-by-step explanation:

It is given that the gradient of the equation is 2. Using slope-form formula, y = mx+b where m is gradient and b is y-intercept. In order to find b, you have to substitute x-coordinate and y-coordinate into the equation :

y = mx + b

m = 2

At(-4,3),

3 = 2(-4) + b

b = 3 - 2(-4)

= 11
