Answer: 13/15
Step-by-step explanation:
1/5 + 2/3 = 13/15. Since 13/15 can’t be simplified, that’s your answer.
C=2(pi)r use this equation with 9 in place of r
Step-by-step explanation:
Let the required number be x.
According to the given information:
Hence the required number is 31.
Answer:
It would be the first one or second one
Step-by-step explanation:
the answer is up ahead
First, let's re-arrange to slope-intercept form.
x + 8y = 27
Subtract 'x' to both sides:
8y = -x + 27
Divide 8 to both sides:
y = -1/8x + 3.375
So the slope of this line is -1/8, to find the slope that is perpendicular to this, we multiply it by -1 and flip it. -1/8 * -1 = 1/8, flipping it will give us 8/1 or 8.
So the slope of the perpendicular line will be 8.
Now we can plug this into point-slope form along with the point given.
y - y1 = m(x - x1)
y - 5 = 8(x + 5)
y - 5 = 8x + 40
y = 8x + 45
