Hey can some one help me, Define a variable and write each phrase as an algebraic expression:
Elena L [17]

Answer:

1. <em>d</em> - 6 ft

where <em>d</em> is the width

2. <em>t</em> + 6 h/week

where <em>t</em> is the amount of time per week Theodore studies

3. <em>t’</em> - 6 a

where <em>t’</em> is Tracy’s age

4. (<em>k</em>/3) - 2

where <em>k</em> is the points that the panthers scored

Step-by-step explanation:

Write the variable and do the operations as described!

“less than” means subtraction, “more […] than” means addition and “one-third of” means division by 3.

Determine whether each sequence is arithmetic. If so, identify the common difference.
-Dominant- [34]

Answer:

Options 1 and 4 are arithmetic

Step-by-step explanation:

Arithmetic means that you are adding or subtracting a number in a sequence.

For option 1, we are adding 2 every time.

-3 + 2 = -1   -1 + 2 = 1   1 + 2 = 3

For option 4, we are subtracting 7 every time.

32 - 7 = 25   25 - 7 = 18   18 - 7 = 11

Option 2 is geometric. Geometric means you are multiplying or dividing by a number in a sequence.

2 * 3 = 6   6 * 3 = 18   18 * 3 = 54

Option 3 is actually quadratic. This is similar to a arithmetic, except instead, the amount added to the number is multiplied by 2 every time.

1 + 2 = 3   (2 + 2 = 4)   3 + 4 = 7   (4 + 4 = 8)   7 + 8 = 15

Use the quadratic formula to solve the equation. If necessary, round to the nearest hundredth. −6y2 − 9y = −1
Tomtit [17]
-6y^2 - 9y = -1

y= \dfrac{-9+ \sqrt{9^2-4*-6} }{2*6}, \dfrac{-9-\sqrt{9^2-4*-6}}{2*6}


y=  \dfrac{-9+ \sqrt{105} }{12}, \dfrac{-9- \sqrt{105} }{12}
