Answer:
b)
Step-by-step explanation:
The line with positive slope is 3x-5y≥15 and the line with negative slope is 2x+3y≤12.
This is because such inequalities represent half planes which are divided by the corresponding lines.
Put (0,0) in both lines to check if the origin lies in the shaded half plane or not.
Parallel has the same slope
2y + 8x = 18
Make it slope in form: y = mx + b
Divide the equation by 2
y + 4x = 9
Now subtract 4x
Y = -4x + 9
The slope is -4
Which equation also has same slope?
Solution: A
Answer:
y = -1/3x + 2
Step-by-step explanation:
y = -1/3x + b
insert the x-intercept to find b
0 = -1/3(6) + b
0 = -2 + b
b = 2
y = -1/3x + 2
The formula is d=C/π.
The diameter is 2 times the radius
The formula for the circumference using the radius is 2πr.
in order to do this backwards, we would have to do 16÷2÷π, but we're not looking for the radius.
Therefore, we take out the ÷2 part, which would be 16÷π
16 is the circumference
16÷π=d
d=C÷π
Answer:
612
Step-by-step explanation:
To find this answer, you can invert the equation:
452.88 = 0.74x
x = 452.88 / 0.74
x = 612
