Answer: 102
Step by Step Explanation:
5y+11=8y-13
-8 -8y
-3y+11=-13
-11 -11
<u> 3y </u>=<u> -24</u> = 8 y=8
3y 3y
5(8)+11=51
Multiple 51 times 2 and you're answer will be the following.
For the first digit there are 7 choices. For the second digit there are 6 choices (because we can't use the same one again). And so on, until there is only one choice for the last digit.
The number of possible codes is this:
7*6*5*4*3*2*1 = 7! = 5040
They will have same slopes but different Y intercepts.
Answer:
x= 3sqrt2 y=3
Step-by-step explanation:
The triangle is isosceles triangle, which means 2 sides are congruent. Therefore, y =3
using the pythagorean theorem,
3^2+3^2=x^2
9+9=x^2
18=x^2
x=18 sqrt
3sqrt2
