Here, (x + 5) matches your answer choices
Answer:
a = 12
Step-by-step explanation:
<u>Pythagoras’ Theorem</u>
a² + b² = c²
(where a and b are the legs, and c is the hypotenuse, of a right triangle)
From inspection of the triangle:
- leg a = a
- leg b = 9
- hypotenuse c = 15
Substituting these values into the formula and solving for b:
⇒ a² + 9² = 15²
⇒ a² + 81 = 225
Subtract 81 from both sides:
⇒ a² + 81 - 81 = 225 - 81
⇒ a² = 144
Square root both sides:
⇒ √(a²) = √(144)
⇒ a = 12
Step-by-step explanation:
it is a line (as the variable x is only occurring with the exponent 1, this makes this a linear equation or simply a line).
all we need to do is find 2 points, mark them in the graph, and the draw a line through both points (and beyond these points).
the first point for me is always for x = 0.
f(0) = 4×0 - 4 = -4
so, the first point is (0, -4)
and for a second point let's pick e.g. x = 2
f(2) = 4×2 - 4 = 4
so, this second point is (2, 4).
