Given,
The linear pair of the equation is,
Required
The solution of the linear equation.
Taking the equation first as,
Substituting the value of y in second equation then,
Substituting the value of x in first equation then,
Hence, the solution of the system is (1, -10).
Answer:
8x^2+3x
Step-by-step explanation:
What I read is 2x+8x^2-4x+5x
combining like terms means putting the terms that have the same variable part together
8x^2 is the only one that doesn't have any terms like it as far as the variable part
so 8x^2+2x-4x+5x
We just need to figure out 2-4+5 which is -2+5=3
So the answer is 8x^2+3x
F(g(x)) where you see an 'x' in f(x) put a g:
f(g(x)) = 1/(g-7), now step by step: g - 7 = 6/x+7-7=6/x, and 1/(g-7)=1/(6/x)=x/6!
I let the second one for you. Sorry if you disagree!
Answer:
180 = 150m + c
177.25 mm
Step-by-step explanation:
L = mT + c
180 = m(150) + c
180 = 150m + c
c = 180 - 150m
181.5 = 210m + c
181.5 = 210m + 180 - 150m
1.5 = 60m
m = 0.025
c = 180 - 150(0.025)
c = 180 - 3.75
c = 176.25
L = 0.025T + 176.25
T = 40
L = 0.025(40) +176.25
L = 177.25 mn
90/15-7/15=83/15 the correct answer to this equation.
