Answer:
153 points
Step-by-step explanation:
Set up a proportion:
34/4 = x/18.
18/4 does not equal a whole number. So, reduce 34/4.
34/4 becomes (when divided by 2 on both the top and the bottom) 17/2.
18/2=9. 9*17=153.
The solution of the equations is the coordinates of the point where the two lines intersects, so the required solution is :
Answer:
y = 2
Step-by-step explanation:
3y - 4 = 6 - 2y
+2y +2y
5y - 4 = 6 (new equation)
+4 +4
5y = 10 (new equation)
/5 /5
y = 2
Lines a and b are parallel, and lines c and d are parallel
Answer:
-1
Step-by-step explanation:
This all comes down to the substitution. I am assuming that (4x2) is meant to be 4x^2 so I will solve as that.
4(-2)^2 = 4(4) = 16
4(-2) = - 8
-2(3)^2 = -2(9) = -18
3(3) = 9
16-8-18+9= -1
