Test contains 10 three-point questions and 14 five-point questions.
Answer:
See the picture attached
Step-by-step explanation:
The graph of y = -|x + 3| is the graph of y = |x| translated three units to the left, since a "+ 3" is applied to the variable x, and next reflected respect the x-axis, since a "-1" multiply the function.
Answer: -2
Step-by-step explanation:
3 squared + 1, -2 +-3
10/-5= -2
Answer:
QR = 13.3
Step-by-step explanation:
We solve using Pythagoras Theorem
c² = a² + b²
RP² = PQ² + QR²
QR² = RP² - PQ²
QR = √RP² - PQ²
RP=15
PQ=7
QR = √15² - 7²
QR = √(176)
QR = 13.266499161
Approximately = 13.3
Therefore, the length of QR = 13.3
Answer:
12x -y = -87
Step-by-step explanation:
You can start with the 2-point form of the equation of a line and manipulate it to give you the standard form.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (-9 -3)/(-8 -(-7))(x -(-7)) +3
y = (-12/-1)(x +7) +3
y = 12x +84 +3
-12x +y = 87 . . . . . subtract the x-term
12x -y = -87 . . . . . . make the leading coefficient positive (per standard form)
