Answer:
x = 1.75y + 0.25z
Step-by-step explanation:
Simplifying
4x + -7y = z
Solving
4x + -7y = z
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '7y' to each side of the equation.
4x + -7y + 7y = 7y + z
Combine like terms: -7y + 7y = 0
4x + 0 = 7y + z
4x = 7y + z
Divide each side by '4'.
x = 1.75y + 0.25z
Simplifying
x = 1.75y + 0.25z

Answer:
Step-by-step explanation:
Statement is not true because
0 is not equal not 38
No x here.
The roots of a polynomial are the values that render the polynomial to zero
y=(x+4)(x-2)^2(x+7)
in the 1st parenthesis, x=-4 render the polynomial =0
in the 2nd parenthesis, x=2 render the polynomial =0
in the 3rd parenthesis, x=-7 render the polynomial =0
So there are 3 values as roots of this polynomial (answer C)
