Answer:
Unknown number, x=-4
Step-by-step explanation:
Forming the equation from the information provided above.
9=2x+17
If we solve for the unknown number, we first collect like terms together.
2x=9-17
2x=-8
Divide both sides of the equal sign by 2 the coefficient of x
x=-4
Answer:
-240
Step-by-step explanation:
Since 20 is right next to -12 that means you have to multiply.
Answer:
The slope of the line with points A(-2, -7) and B(3,5) is m = (12/5).
Step-by-step explanation:
The two pints are given as A(-2, -7) and B(3,5)
Slope of a line with points (a,b) and (c,d) is given as

So, here the slope of line AB is

or, m = 12/5
Hence, the slope of the line with points A(-2, -7) and B(3,5) is (12/5).
