29.2 to the nearest tenth is 29.2
Answer:
-19
Step-by-step explanation:
First we set the equation up:
-8X - 46 = -6X - 8
Then we simplify:
-2X = 38
Then we get the answer by dividing 38 by -2:
X = -19
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)
