$0.19+$0.12=$0.31A two minute call would cost $0.31
Answer:
B) 2
Below I wrote the steps on how I would find the answer.
Step-by-step explanation:
1. Yep, so basically cba = cbl + lba.
2. So you need to find x
3. So basically if you set up the equation 61x - 2 = 13x - 1 + 95
4. Then you can solve for x
5. X = 2
Answer:
Step-by-step explanation:
Both equations should be in slop-intercept form (y=mx+b)
So add -2x to -6. Your equation should look like this
y=2x-6
In y=mx+b
b will fall on y-axis
mx is rise/run
So in the first equation plot -6 on y axis and go up 2 and over 1(because 2x is equivalent to 2/1 x)
In the second equation plot -1 on the y axis. Then go up 1 and over 3 from that point.
Answer:
See below
Step-by-step explanation:
<em>Vector argument</em>
Vector DF is (5, -4) - (5, 5) = (0, -9).
Vector EG is (2, 2) - (8, 2) = (-6, 0).
The dot-product of these two vector is (0, -9)•(-6, 0) = 0·(-6) + (-9)·0 = 0.
When the dot-product of two vectors is zero, those vectors are at right-angles to each other. Therefore diagaonal DF ⊥ diagonal EG.
_____
<em>Alternate argument</em>
The x-coordinates of points D and F are the same, so diagonal DF is a vertical line. The y-coordinates of points E and G are the same, so diagonal EG is a horizontal line. Vertical lines are perpendicular to horizontal lines, so DF ⊥ EG.
