Answer:
6*x-8
Step-by-step explanation:
Remember pemdas and go down the list
Product is a form of multiplication and less than is subtraction
Answer:The last one
Explanation:
A function has to return a unique value when given an argument. In the last set
} ( – 2 , 1 ) , ( 3 , – 4 ) , ( – 2 , – 6 )}
, the argument -2 is supposed to return both 1 and -6 : this is not possible for a function.
Step-by-step explanation:
Well you are going to need a rule or formula like x + 6 or 3 (x) + 2
Example:
Input x + 6 Output
2 2+ 6 8
4 4+6 10
6 6+6 12

Answer:
(a) x = -1.10 and x = 1.10
Step-by-step explanation:
A straightforward square root will give the value of x.
<h3>Solution</h3>
Divide by the coefficient of x^2:
x^2 -30/25 = 0
x^2 -1.20 = 0
Add 1.20, and take the square root.
x^2 = 1.20
x = ±√1.20 ≈ ±1.0954
x ≈ -1.10 and 1.10 . . . . . round to hundredths

<em>Additional comment</em>
For small values of x, the root of (1+x) is approximately 1+x/2. For a root accuracy to the nearest hundredth, x < 0.21 (as here). For accuracy to the nearest thousandth, x < 0.064.
In a triangle all the angles add up to 180 degrees.So we know that
(6x-1)+20+(x+14)= 180
6x+x+14-1+20=180
v v
7x + 13 + 20= 180
v
7x + 33=180
-33 -33
0 147
7x/7 = 147/7
x = 21
x=21
Then you substitute:
(6x-1) (x+14)
(6×21-1) (21+14)
v v
126-1 35
125 degrees / 35 degrees
125+35+20=180
