Answer:
m = -2
Step-by-step explanation:
To get the slope of the line, we are going to use the 2-points slope equation form
That will be;
m = (y2-y1)/(x2-x1)
(x1,y1) = (-5,11)
(x2,y2) = (8,-15)
m = (-15-11)/(8-(-5)) = -26/13 = -2
The possible mistake she might have made is placing the x-values difference over the y and her formula will look like;
m = (x2-x1)/(y2-y1)
It is an error of switching the numerator for the denominator
The solution would be: a = 3/4
Answer:
x=65
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
5/4*x-(3/2)=0

Calculating the Least Common Multiple :
3.1 Find the Least Common Multiple
The left denominator is : 4
The right denominator is : 2
20 x 3.2 = 64.0
It is equal to 64 because of you do long multiplication, it is 32 x 20 then add back in the decimal point in between the 4 and 0 for the answer.
Answer:
24
Step-by-step explanation:
x + x + 1 = 49
x + x = 2x = 48
x = 48 ÷ 2 = 24
