Answer:
C.(-3, -3) and (-3,3)
Step-by-step explanation:
When we have a vertical line the slope is undefined.
That means the x values stay the same
C.(-3, -3) and (-3,3)
This has the same x values
m = (y2-y1)/(x2-x1)
=( 3- -3)/(-3 - -3)
(3+3)/(-3+3)
6/0
undefined
Answer:
(6,1)
Step-by-step explanation:
after switching the equations from y=mx+b, graph both equations. you will see that the point of intersection is (6,1)
Notice the picture below
now, we know their perimeter are the same for both
thus 4(a+4) = 6a
solve for "a"
Answer:
Stock A
Stock B
Step-by-step explanation:
When we say something is increased (or decreased) by a percentage, we mean that the percentage of the original amount is added to (or subtracted from) the original amount.
Of course, you know that 5% = 5/100 = 0.05, so that an increase of 5% in d would be ...
d + 0.05d . . . . . 5% of the original amount (d), added to d
Factoring out d gives another version of this expression:
d(1 +0.05)
and combining the numbers gives yet another version of the same expression:
1.05d
These are the ways that the increase in Stock A can be expressed:
d +0.05d
d(1 +0.05)
1.05d
__
Similarly, if the "increase" is negative, as for Stock B, we can use the same sorts of expressions. +0.05 gets replaced by -0.05, but the form of the expression is the same.
d - 0.05d . . . . . the original amount decreased by 5%
d(1 -0.05) . . . . .d factored out
0.95d . . . . . . . . the numerical coefficient simplified
