Answer:
f(-3) = 18
Step-by-step explanation:
We need just substitute x with (-3) and calculate it.
f(-3) = (-3)² -2*(-3) + 3 = 9 + 6 +3 = 18
Answer: 
<u>Step-by-step explanation:</u>
When you subtract b/2a from both sides, you end up with the Quadratic Formula.
To find the number of minuets you spent playing your game and reading you would solve this equation
35+(8x4)
X = x
to solve, subtract both sides by x:
0 = 0
x is always equals to x so infinite solutions
Answer:
AA similarity postulate
Explanation:
For triangle XZY, the angles are 90°, 40°, 50°.
For triangle AXB, the angles are 90°, 40°, 50°.
Which states that all the angles are of equal measure in the triangles.
This is stated by AA similarity theorem meaning when two angles are equal in the triangle. Then the triangles are congruent to each other.
