For the first one, you're answer would be AC. since C is also a right angle, and angle A is hypnotenuse to C
Answer:
There are no options, so i will answer in a general way.
In a function:
y = f(x)
The output is y, and the input is x, and the ordered pair is written as (x, y)
In this case, we have the function:
y = -7*x + 6
Then we need to have different inputs and then find the outputs for each.
For example, if x = 1.
y = -7*1 + 6 = -1
Then we have the ordered pair (1, - 1)
if x = 0
y = -7*0 + 6 = 6
then we have the ordered pair (0, 6)
The general ordered pair is written as:
(x, y = -7*x + 6)
or:
(x, -7*x + 6)
Where you only need to replace the value of x.
Answer:
when
Step-by-step explanation:
<em>Answer</em>
= 11
<em>Explanation</em>
f(x) = x² + 3x- 7
To get the value of f(x) when x = 3, we substitute x with 3 in the function f(x).
f(x) = x² + 3x- 7
= 3² + (3×3) -7
= 9 + 9 - 7
= 11
