Dam I forgot :/ wha it was
Substitution involves replacing part of one equation with the other equation. In this case, the second equation is already solved for y. All we have to do is replace y in the first equation with 12x+3.
8x - (1/3)(12x+3) = 0
Distribute the -1/3
8x - 4x - 1 = 0
4x - 1 = 0
4x = 1
x = 1/4
Now plug 1/4 in for x to solve for y.
12(1/4) + 3 = y
y = 6
Answer: (1/4, 6)
90
55+65=120
there are 3 numbers and when you divide them it makes 70.
70 x 3 = 210
210 - 120 = 90
55 + 65 + 90 = 210
210 / 3 = 70
Answer:
Step-by-step explanation:
the only difference i can think of is that x = 0 is actually saying that 0 is a solution. f(0) is just asking you to plug in zero for x, rather than saying it is the actual solution.
Answer:
x is 70°
hopefully this will help u
