You will read for 45 minutes if your brother reads for 15 minutes.
<em><u>Explanation</u></em>
You decide to read 30 minutes longer than your brother reads.
If your brother reads number of minutes, then 30 minutes longer than minutes means minutes.
As the number of minutes you read is , so the equation will be:
When your brother reads for 15 minutes, then we will just <u>plug into the above equation</u>. So.....
So, you will read for 45 minutes if your brother reads for 15 minutes.
Answer:
Step-by-step explanation:
The graph that would give the result of an integration and hence f would be the top one. f = x^4/4 - x^3 + a constant (perhaps zero) would look like the top graph. Just to show you that is true, I've enclosed a graph. The graph is of f which is given 2 lines up.
Answer:
-4
Step-by-step explanation:
y-3=-4(x-5)
y=-4x+20+3
y=-4x+23
y=mx+b where m=slope and b=y-intercept
Answer: false
Step-by-step explanation:
Answer:
f(4) = -15
Step-by-step explanation:
Since we have an average rate of change, we can deduce that a line, with a gradient of -6 joins the points on the function, f, when the parameter is 1 and when it is 4, i.e. the line passes through the point (1, 3) and has a gradient of -6;
From this, we know that for every value of x we increase the, value y will decrease by 6;
So if we increase 1 by 3, to get to 4, the y value must decrease by 18 (3×6);
Written mathematically, it would look like:
f(4) = 3 + (4 - 1)(-6)
= 3 - 18
= -15
(4, -15)
