Answer:
=−6y−20
Step-by-step explanation:
Let's simplify step-by-step.
−13−2y−7−4y
=−13+−2y+−7+−4y
Combine Like Terms:
=−13+−2y+−7+−4y
=(−2y+−4y)+(−13+−7)
=−6y+−20
Using the degree of freedom rule, we can solve three unknown variables if and only if the number of independent equations is equal to 3. Thus the number of equations should be equal to the number of variables. We can use substitution to find x.
<span>g(x) = 2k(x) (1)
</span><span>g(x)=2x^+3x+10 (2)
k(x)=2x+16 (3)
we substitute 2 to 1 and also 3 to 1. The resulting function hence becomes:
</span>2x^+3x+10 = 2 * (2x +16)
Simplifying the equation on the right.
2x^+3x+10 = 4x +32
we group then the like terms on one side. That is,
2x^+3x - 4x+10 -32 = 0
2x^2 - x - 22 = 0
The factors using the quadratic equation are
x1 ==1/4+1/4√<span>177
</span>x2 ==1/4-1/4√177
B. 5
Remove the parentheses
7+3i-2-3i
Since two opposites add up to zero, remove them form the expression
7-2
Subtract the numbers
