Hi there,
9. Which of the following is the value of x in the solution to the
system of equations given below?
8 + 2x = 5y (1)
4x - y = 2 (2)
▪ (1)
y = ( 8 + 2x ) ÷ 5
▪ (2)
4x - [( 8 + 2x ) ÷ 5] = 2
( 20x - 8 - 2x ) ÷ 5 = 2
20x - 8 - 2x = 2 × 5
20x - 2x = ( 2 × 5 ) + 8
18x = 10 + 8
18x = 18
x = 18 ÷ 18
x = 1
The answer is : A. 1

Answer:
2x-2=-4
5/8x3/5= 15/40 then u simplify and get -4 3/8
Answer:37
Step-by-step explanation:
The expression for the polynomial graphed will be y(x) = (x + 3)(x - 1 )(x - 4 ).
<h3>How to factor the polynomial?</h3>
From the graph, the zeros of the polynomial of given graph are:
x = -3
x = 1
x = 4
Equate the above equations to zero
x + 3 = 0
x - 1 = 0
x - 4 = 0
Multiply the equations
(x + 3)(x - 1 )(x - 4 ) = 0
Express as a function gives;
y = (x + 3)(x - 1 )(x - 4 )
Hence, the factored form of the polynomial will be y = (x + 3)(x - 1 )(x - 4 ) .
