1. 5cm
2. 10cm
3. 20cm
4. 40 cm
Step-by-step explanation:
I think you need to double the area of the scaled factor.
Answer:
Undefined slope.
Step-by-step explanation:
The formula should be y2 - y1 over x2 - x1
Points ( 20,-16 ) and ( 19, -16 )
So ( -16 - ( -16 ) ) over ( 19 - 20 )
0 over -1
The slope is 0. Undefined.
Answer:
17.83
Step-by-step explanation:
d = r*t
d = 41 miles
t = 2.3 hours
r = ??
d = rt Substitute
41 = r * 2.3 Divide by 2.3
41 / 2.3 = r Switch sides
r = 41/2.3
r = 17.83 mph Answer
Answer:
Let
S= #small candles
L= #Large candles
S+ L =>20
3.50S + 5.00L < 80
Step-by-step explanation:
Answer: Choice A
y + 1 = -3(x+2)
=============================
Explanation:
Let's look through the answer choices.
Choices C and D show that the point (2,1) is on the line. But the graph does not show this. So we can rule out choices C and D.
With choice A, the slope is negative and choice B has a positive slope.
The answer must be choice A because the line is going downhill as we move from left to right.
--------------
A common method is to pick two points on the line and compute the slope using the slope formula
m = (y2-y1)/(x2-x1)
Once you know the slope, you would use point slope form
y - y1 = m(x - x1)
