The equation is y = mx + b
(18, -19)
substitute these numbers in the equation
-19 = 0(18) + b
-19 is y because it is the y slot in the cordinate and I put 0 for m because m is the slope and x is 18
-19 = 0 + b
b= -19
the equation is
y = 0(x) - 19
y = -19
Add 7 to both sides.
-3y = 9
Divide -3 on both sides.
y = -3
Hope this helps!
Answer:
Step-by-step explanation:
I am very sorry if this doesnt make sense but i tried to give you an example for the first one so you could figure out the 4 and 5.
If y=12 when x=6, determine y when x=18.
Ok if y=12 and x=6 they add up to 18. So X=6 then you are going to have to times 6 by three to get x to equal 18. That means we have to times y by 3 also which equals 36. We can check this by making sure they are congruent or the same. So if the origanal question said y equals 12 and x equals 6. How do you make sure it's the right answer? What do they have in commmon? Well to get 12 you have to multiply 6 by 2 to get 12. And to get 6 you have to divide 12 by 2. So the common number is 2. So for x to equal 18 we have to figure out is the have something in common, so 18 times 3 equals 36 and if 36 divided by 3 we get 18. So the common number is 3.
Answer:
x=19
Step-by-step explanation:
2x - 8 = 30
get x by itself by adding 8 to both sides
2x=38
divide by 2
x=19
You want to prove
By the definition of the limit, this means that for any
