Answer:
Answer below
Step-by-step explanation:
The y-intercept is 2, so you know that one point will be (0,2). The slope is 2/3 so you go 2 units up and 3 units to the right from (0,2).
Answer:
2x+6=20
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)
Answer:
x³ * x³ * x³ = x³⁺³⁺³ = x⁹
x³*³*³ = x²⁷
x⁹ ≠ x²⁷
x³*³*³ it´s wrong
x³⁺³⁺³ = x⁹ it´s correct
