Answer:
y=7
x=5
Step-by-step explanation:
x-y=-2
+y +y
x=-2+y
then substitute -2+y into the x in the other equation
so:
2(-2+y) + 4y = 38
-4+ 2y +4y = 38
-4+6y= 38
+4 +4
6y=42
divide both sides by 6
y=7
to get X:
x-y=-2
x-(7)=-2
+7 +7
x=5
just give the other kid brainiest
Step-by-step explanation:
Step-by-step explanation:
it's a function.
the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.
the domain is (1,3,7,8)
the range is (2,4,6,9)
J------------K------------L
8x+11 14x-1
<span>If K is the midpoint of JL then JK = KL
8x+11 = 14x-1
11 + 1 = 14x - 8x
12 = 6x
x = 12/6
x = 2
JK = 8x + 11 = 8*2 + 11 = 16+11 = 27
KL = JK = 27
JL = JK + KL = 27 + 27 = 54</span>
