Awnser: (15,15)
The image of (3,3) after a dilation by a scale factor of 5 centered at it's origin would be (15,15), I believe. From what I remember, if it's asking for a dilation by a scale factor, you're basically just multiplying that point (the 3,3) by whatever the scale factor is (5 in this case). So for example, here you would just multiply the (3,3) by 5, since 5 is our scale factor. And you would get (15,15). I hope this helps, I'm quite new to this.
(2) + (2)
=> 8x - 6y = -46 ———(3)
(1) + (3)
=> 5x + 6y + (8x - 6y) = 20 - 46
=> 13x + (6-6)y = -26
=> 13x + 0y = -26
=> 13x = -26
=> x = -26/13
=> x = -2
=> 5(-2) + 6y = 20
=> 6y = 20 + 10
=> 6y = 30
=> y = 5
x = -2, y = 5 => C
Answer:
52.08$
Step-by-step explanation:208.32$/4 tires=52.08$
Remove the parenthesis first tho !!!
Substituting y=6x+2 into equation 3y - 18x =12 looks like:
3(6x + 2) - 18x = 12
18x + 6 - 18x = 12 distributive property left side
6 = 12 simplifying the left side
We now see a contradiction: 6 does not equal 12 What this tells us is that there is no solutions to this equation. So choice 'C' ...
