The system has one solution, so it is consistent independent. The graphs intersect at the point (2, 8), which can be checked algebraically.
Complete a table of values for each line.
The point (2, 8) is the solution to the system of equations. Since (2, 8) is the solution to the system of equations, Lucia has 2 dimes
and 8 nickels.
hope it helps :) feel free to ask anymore questions
NightowlIt can be proven that between any two real numbers there exists a rational number. Therefore there exists a rational number r such that
<span>7.7+<span>2–√</span><r<7.9+<span>2–√</span></span>By calculator we can find a rational number r that satisfies these condition, I choose 9.2. Now subtract square root 2.<span>7.7<9.2−<span>2–√</span><7.9
</span>so the answer is between 7.7 and 7.9
rational number : 7.8
<span>irrational number : 9.2 - √2</span>
Answer:
x=5,y=1 and z=-2
Step-by-step explanation:
We are given that system of equation
(I equation)
(II equation )
(III equation )
Equation II multiply by 3 then add with equation I
Then, we get
....(Equation IV)
Subtract equation II from equation III then we get
(equation V)
Adding equation IV and equation V then, we get
Substitute x=5 in equation V then, we get
Substitute x=5 and y=1 in equation then, we get
Hence, the solution for the given system of equation is given by
x=5,y=1 and z=-2
Answer:
an open circle means it contains no equal signs.....everything to the left is shaded....means it is less then
x < 1 (thats a less then sign only) ....no equal sign in there
