3k + 15 = 66
3k = 66 - 15
3k = 51
k = 51/3
k = 17
Answer:
y=7 and x=-8
Step-by-step explanation:
Isolate x in the first equation:
10x=-17-9y
x=(-17-9y)/10
Substitute into the second equation:
7*((-17-9y)/`10)+10y=14
-119/10+37y/10=14
-119+37y=140
37y=259
y=7
Putting this into the first equation, we get that x=-8
Answer:
f(x) = -(x+4)^3
Step-by-step explanation:
Reflection over the x-axis negates every y-coordinate. The reflected function is ...
f(x) = -(x+4)^3
Answer:
true for all real numbers
Step-by-step explanation:
Subtracting z from both sides gives ...
9 ≤ 19
This statement is true for all values of z. The solution is "all real numbers."
