Answer:
Step-by-step explanation:
slope =
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y + 3 = (x - 2) is in this form
with slope m =
Using linear function concepts, it is found that the speed of the motorboat is of 22 miles per hour.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
In this problem, each second, the position increased by 22, hence the slope is of 22. Since velocity is the distance divided by the time, which in this problem is the slope, the speed of the motorboat is of 22 miles per hour.

so hmm notice, we use the decimal format for the percent, namely 15% is just 15/100 and 5% is just 5/100 and so on
whatever the amounts of "x" and "y" are, they must add up to 100 grams
thus x + y = 100
and whatever the concentrated amounts are, they'll add up to (100)(0.15)
thus
solve for "x", to see how much 5% alloy will be needed
what about "y"? well y = 100 -x
6.7-2.3= 4.4 is the answer to the problem
Answer:
Slope is technically 1, because it implies that it's going up one and over to the right one. Also in slope-intercept form it would look like this
y = x + 1.

Hope this makes sense :)
