Answer:
Step-by-step explanation:
4(2+3x)= 4(2+12) = 4× 14= 56
8+12x =8+12×4=8+48= 56
Yeah, it's equal! Have a great day!
Answer:
The slope is 10/4
Step-by-step explanation:
To get x/y, you need to know the values of "x" and "y".
So, we'll need 2 equations.
Where are they?
Let's see, you have a ratio isn't it?
You can make two equn: out of them.
e.g. in 1/3, multiplying both numerator and denominator with 4 will give you 4/12. So, you can write as 1 x 4 = 4 and 3 x 4 = 12.
Similarly, in the given ratio
(x+y)/(x-y) = a/b, we may write
x + y = ak -----(1)
x - y = bk -----(2) where "k" is a constant.
equn: (1) + (2) ---> 2x = k (a+b)
therefore, x = k(a+b)/2
and you will get y = ak - k(a+b)/2
y = k (a-b)/2
Therefore, x/y = (a+b)/(a-b)
Answer: We all hate it when we are stuck! The slope is -1/2.
Step-by-step explanation: To find the slope, figure out the change of x divided by the change of y. The change of y is -1, and the change of x is 2. Therefore, the slope of the line is -1/2.
