Answer: g(x) = 5x+9, second choice</h3>
Explanation:
When we reflect over the vertical y axis, every negative x value becomes positive and vice versa. So we effectively replace x with -x like so
f(x) = -5x+9
f(-x) = -5(-x)+9 ... replace every x with -x
f(-x) = 5x+9
g(x) = 5x+9
A point like (1,4) on f(x) will reflect over to (-1,4) on g(x). If we apply this to every point on f(x), then all of f(x) will reflect to g(x).
Answer:
C
Step-by-step explanation:
∠ FHI and ∠ JHI form a straight angle and are supplementary, thus
3x + x = 180, that is
4x = 180 ( divide both sides by 4 )
x = 45
Thus
∠ FHI = 3x = 3 × 45 = 135° → C
Answer:
19
Step-by-step explanation:
From the question we have been given this data
y=ax+b
a=−1.077
b=30.98
r2=0.744769
r=−0.863
Where
X = number of situps
Y = number of hours spent watching tv
We have x = 11
Inputting this into the formula we have
Y = (-1.077)(11) + 30.98
Y = −11.847 + 30.98
Y = 19.133
Which is approximately 19
Therefore we conclude that a person who watches TV for 11 hours can do 19 situps.
