If we take for example 20x1.5=30 the scale factor would create an enlargement
Answer:
you need the formula for the cone , Korc
Step-by-step explanation:
formula for cone =
*π*
*h
they tell us that the diameter is 8 so r = 4
and that h = 9
volume of cone =
*π*
*9
VoC = 150.796
VoC = 150.8 ( to the nearest 10th)
Answer: The gradient of the line passing through is 3, thus the equation of the line becomes y=3x-4.
Step-by-step explanation: The parallel lines gradients that have similar gradients, so now we have the gradient of 3 because its similar to the other gradient. To get the equation of the line we use this equation: y=mx+c, we have to substitute the x and y to get the constant c.
5=3(3)+c
c= -4
y=3x+c
Answer:
(3,2)
Step-by-step explanation:
I graphed the two lines using a graphing tool. The lines intercept at (3,2). Therefore, the solution to the system is (3,2).
Hello,
answer A
4x+2y=11
x-2=-2y==>2y=-x+2
4x-x+2=11==>3x=9==>x=3
2y=-3+2==>y=-1/2
