y^2 = x isn't a function because there is at least one value of x that produces multiple values of y. In fact, any x value greater than 0 yields two y values. If x = 0, then y = 0 is the only solution. ... Graphically, the equation fails the vertical line test, which is another way to determine that it is not a function.
2(4x+5)>7x+20 perform indicated multiplication on left side
8x+10>7x+20 subtract 7x from both sides
x+10>20 subtract 10 from both sides
x>10
or in interval notation, x=(10, +oo)
Answer:
y=6
Step-by-step explanation:
(2y-3)*2=4y-6
You multiply by two because there are two sides that are considered the length
y+1*2=2y+2
Same thing here
4y-6+2y+2=32
6y-4=32
+4. +4
6y=36
/6 /6
y=6
Answer:
16
Step-by-step explanation:
55-7= 48
48/3 = 16
Answer:
5 and 4
Step-by-step explanation:
So if, x equals 2 then all you do is turn the x into a 2.
So you rewrite the equation into,
2 + 3 and 2 x 2,
Which would be 5 and 4
Hope this helps!
