Answer:
y=4x
Step-by-step explanation:
you just have to find the slope!
Answer:
7
Step-by-step explanation:
solving algebraically:
(x = the unknown number)
(our goal is to isolate x/get x by itself)
2x + 5 = 5x - 16 {equation written out}
-2x -2x
5 = 3x - 16
+ 16 + 16
21 = 3x
÷3 ÷3
7 = x
check:
(2)(7) + 5 = (5)(7) - 16
14 + 5 = 35 - 16
19 = 19
hope this helps!!
1.420 is bigger because you added a zero to it and that makes it in the Hundredths and in 1.42 the 2 is in the tenths place
