Answer:
<em>The slope of the line is -1</em>
Step-by-step explanation:
<u>Slope of a Line</u>
Suppose we know a given line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated as follows:
From the table in the image, we select the points (1,4) (3,2). The slope is:
Now select two other points like (5,0) (7,-2)
Following the same procedure with any other pair of points, we'll get the very same result:
The slope of the line is -1
Answer:
Step-by-step explanation:
6x^3 - 3x^2 - 45x = 3x(2x^2-x-15) = 3x((2x+5)(x-3)
This question is worded weirdly, but it means:
8 / (5/2)
= 8 * (2/5)
= 16/5
Answer:
Step-by-step explanation:
a93 = 93 + 2(52 − 1)
a93 = 93 + 2(52 + 1)
a93 = 52 + 2(93 + 1)
a93 = 52 + 2(93 − 1)
Originally 52 - Get rid of the first 2
a93 = 52 + 2(93 + 1)
a93 = 52 + 2(93 − 1)
2 each week. - Annoying. That doesn't help.
a93 = 52 + 2(93 + 1)
a93 = 52 + 2(93 − 1)
We're not buying any new ones in the first week, so purchases are one down.
a93 = 52 + 2(93 − 1)
I think we made it.
Answer:
Yes
Step-by-step explanation:
Substitute the x and y values in for x and y to check.
-1 = 7 - 8
-1 = -1
In this instance, (7, -1) is a solution of y = x - 8.
