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)
Answer:
The corresponding element is 44 3/5
Step-by-step explanation:
Here, we want to calculate the f(x) value given the x value
what we simply do is to substitute 8 for x
we have this as;
f(8) = 6(8) - 17/5
f(8) = 48-17/5
f(8) = (5(48) - 17)/5
f(8) = 223/5 = 44 3/5
Answer: 2:7 times
Step-by-step explanation: hope it helps u
If they have opposite signs the point can be in either the second or fourth quadrants.
-x and +y is in the second quadrant
+x and -y is in the fourth quadrant.
