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)
Answer:14.7
Step-by-step explanation:
d = l^2+w^2+h^2 = 10^2+4^2+10^2≈ 14.69694cm
Answer:
9
Step-by-step explanation:
The answer to | − 12 + 3 | is 9 because if you add -12 + 3, you get -9. However, since it is the <em>absolute value</em>, we would make it the same number but positive.
Hope this helped! :)
49 increased by d is 49 + d but I feel that this isn't the whole statement...?
Would -3,-4 be your answer to get the X intersept
