LekaFEV [45]
Hello there!

So, if this turtle is only going 2.5 miles per hour. This would mean that (EACH) hour, this turtle only arrived 2.5 miles. So, we do,

\boxed{10.0 \left \{ {{2.5+2.5=5.0} \atop {2.5+2.5=5.0}} \right.}

We would have to count how many ("2.5's" they are above.)

We count only 4.

I would take this turtle 4 miles to swim 10 kilometers.

Rewrite the following equation in slope-intercept form. 14x + 15y = 11 Write your answer using integers, proper fractions, and i
Goshia [24]
Answer:
y = (-14/15) x + (11/15)

Explanation:
The slope-intercept form has the following formula:
y = mx + c
where:
m is the slope
c is the y-intercept

The given is:
14x + 15y = 11

To put this in slope-intercept form, we will need to isolate the y as follows:
14x + 15y = 11
15y = -14x + 11
y = (-14/15) x + (11/15)
were:
m is the slope = -14/15
c is the y-intercept = 11/15

Hope this helps :)
