The answer to the question
So first we have to find out what the bottom number is so
8x+14
subsitute 8 for x
8(8)+14
64+14
78
so 156/78
an easy way to do this is to factor it out and find the 'ones' like 4/8=1/2 times 4/4 (4/4=1 and can be canceled out)
*=times
156=2*2*3*13
78=2*3*13
so (2*2*3*13)/(2*3*13)
2/1 times (2*3*13)/(2*3*13)
we can cross out the (2*3*13) and get
2 as the answer
Answer:
33 = r
Step-by-step explanation:
The circumference is given by
C = 2 * pi *r
207.24 = 2 * 3.14 *r
207.24 = 6.28 *r
Divide each side by 6.28
207.24/6.28 = 6.28 r /6.28
33 = r
Answer:
Step-by-step explanation:
8 multiplied by .75 = 6 which is 25 percent off.
Answer:
y =
+ 2
Step-by-step explanation:
The slope of the line that has an x intercept of (2,0) and y-intercept of (0,-6) is:
Slope(s) = Change in y ÷ change in x
s =
= 3
The slope of the perpendicular line to this line with slope of 3 has to have a slope of -1 ÷ 3 = 
Reason: The product of slopes of lines perpendicular to each other have to be -1
So the slope of the perpendicular line that passes through (-6,4) is 
As mentioned earlier, we derive a slope of a line by dividing the change in y by the change in x
Taking another point (x,y) on the line,
= 
= 
y - 4 =
x - 2
y =
x + 2
