Answer:
The coordinates of Q and S are;
(-5,8) and (1,-3)
Step-by-step explanation:
When we reflect a point with coordinates (x,y) across the y-axis, we get a new point with the coordinates (-x,y)
So (5,8) becomes (-5,8)
and (-1,-3) becomes (1,-3)
Answer:
A) 252 ways (use 'n choose k' formula)
B) 6 ways (use 'n choose k' formula again).
C) 6/252 basically elementary combinatorics
Answer:
x=5
Step-by-step explanation:
35 = 7x
Divide each side by 7
35/7 = 7x/7
5 = x
We know: The sum of the angles of each quadrilateral is 360°.
Therefore we have equation:
x + 3x + 4x + 2x = 360
10x = 360 |:10
x = 36

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
f(x) = 4(2)ˣ
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em> [Function f(x)]: f(-3) = 4(2)⁻³
- Exponents: f(-3) = 4(1/8)
- Multiply: f(-3) = 1/2
