Answer:
C. Cubic expression.
Step-by-step explanation:
The highest exponent is 3 ( in the term 7x^3) so it is cubic.
A graph shows x-3 to be a factor, selection B.
The factorization would be (7x +3)(x -3).
Answer: One and fifty six thousandths
Step-by-step explanation:
The 1 represents one so that first the decimal point represents and so that’s second 56 represents the thousands place so it would be fifty six thousandths since it is on the right side of the decimal.
Answer:
x = -5
y = 0
Step-by-step explanation:
x-y = -5 -----eqn 1
x-y = 1/3 ------eqn 2
From eqn 1
x-y = -5
x = -5 + y -----eqn 3
From eqn 1
-5+y-y = -5
y = 0
Eqn 3
x = -5 + 0
x = -5
In finding the matching value of one unknown variable when other is known we have to use substitution. By way of substitution, y = 3 (0) + 4; y = 4. Moreover, when the variable of the known variable is zero, we just have to identify the intercept of line in the equation. The number with no variable in its side is always the intercept of the equation.
