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:
D 6
Step-by-step explanation:
substitute in 1 for x
2(1)= 2
2+4= 6
y=6 when x=1
If is
x > 2 or x < 7 ⇒ x is any real number
If is
x > 2 and x < 7 ⇒ 2 < x < 7
A set of all numbers that are greater than 2 and less than 7.
Look at the picture.
Answer:
So first you know automatically that either side of the line is 180 degrees. So 180-155 would get you 25 degrees so you now know that y=5. we know that it is also a right angle therefore you divide 65 (x-90) by 13 and you get that x is also equal to five
