Answer:
d
Step-by-step explanation:
5x + 4 = -6
5x= -6-4
5x=-10
x=-2
The value of the first expression is x=-2.
x/2 + 3 = 2
x/2 = 2-3
x/2 = -1
x=-2
The value of the second expression is x=-2.
2x+14=10
2x=-4
x=-2
The value of the third expression is x=-2.
-2=-x
2=x
The value of the fourth expression is x=2.
Answer:
99
Step-by-step explanation:
Since given, < 100.
So,
100 - 1 = 99
Answer:
How would the function change if the base of the exponent were between 0 and 1? If the base of the exponent were 1, the function would remain constant. The graph would be a horizontal line. If the base of the exponent were less than 1, but greater than 0, the function would be decreasing.
Step-by-step explanation:
(x² + 3x - 1)(2x² - 2x + 1)
x²(2x² - 2x + 1) + 3x(2x² -2x + 1) -1(2x² - 2x + 1)
2x^4 - 2x³ + x² + 6x³ - 6x² + 3x - 2x² + 2x - 1
2x^4 - 2x³ + 6x³ + x² - 6x² - 2x² + 3x + 2x - 1
2x^4 + 4x³ - 7x² + 5x - 1
<span>(D)The result 2x4 + 4x3 − 7x2 + 5x − 1 is a polynomial.</span>
Answer:
The value of x in this equation is 8.
Step-by-step explanation:
5x - 1 = 6x - 9
Subtract 6x on both sides.
-x - 1 = -9
Add 1 to both sides.
-x = -8
Divide by -1 on both sides.
x = 8
