Answer:
12
Step-by-step explanation:
ΔBAD is similar to ΔCBD. So we can write a proportion:
BD / CD = AD / BD
h / 16 = 9 / h
h² = 144
h = 12
Answer:
The perpendicular line would be y = -1/2x
Step-by-step explanation:
Perpendicular lines have opposite and reciprocal slopes. This means that we take the original slope (2) and negate it (-2). Now that we have the negated version, we need to flip it (-1/2).
With the slope of our new equation decided, we simply need to plug it along with the point into point-slope base form and then solve for y.
y - y1 = m(x - x1)
y + 4 = -1/2(x - 8)
y + 4 = -1/2x + 4
y = -1/2x
Answer:
The family bought 2 bags of chips
Step-by-step explanation:
Let the number of chips bags be = x
The number of candy bars = twice as much as the number of bags of chip
The number of candy bars = 2x
The total cost spent is = $5.50
Therefore cost of all the chips bags + candy bars = 5.50
2x + x = 5.50
3x = 5.50
x = 
x = 1.83
x = 2 (approx)
Thus the number of chips is 2 and the candy bars is 2(2) = 4 bags
