<span>45 m in 10 seconds
45/10 = 4.5 ...this to find the rate per second.

2 minutes = 2*60 = 120 seconds.

120 * 4.5 = 540

Answer: bee flies 540 m in 2 minutes.</span>

Okay so if there are 120 seconds in 2 minutes and the bee flies 45m in 10; 10 goes into 120 12 times so just multiply 45 by 12. the answer is 540

Three consecutive terms of an arithmetic sequence have a sum of 12 and a product of -80. Find the terms. Hint: let the terms be
Shalnov [3]
(x - d) + x + (x + d) = 12 --> Create an equation using the first piece of information - "Three consecutive terms... have a sum of 12"

x - d + x + x + d = 12 --> Simplify the left side of this equation (d cancels out)

3x = 12 --> Divide both sides by 3

<u>x = 4
</u>


Use the value of x (x = 4) to find the value of d. To do this, set up another equation using the second piece of information.

(x - d) * (x + d) * x = - 80 --> "Three consecutive terms... have... a product of -80". Then, substitute the value of x (4) into this equation.

(4 - d) * (4 + d) * 4 = - 80 --> Multiply out the sets of brackets, the * 4 is dealt with afterwards

4(16 - 4d + 4d - d²) = - 80 --> Simplify the expression inside the brackets

4(16 - d²) = - 80 --> Multiply out these brackets by the 4

64 - 4d² = - 80 --> Subtract 64 from both sides

- 4d² = - 144 --> Divide both sides by - 4

d² = 36 --> Square root both sides

<u>d = 6

</u>
Now, find the values of the terms of the sequence by using substituting the values of x and d into the expressions given.
<u>
</u>
<u />1. x - d = 4 - 6 = <u>- 2
</u>
<u></u>2.<u> x = 4</u>
3. x + d = 4 + 6 = <u>10
</u>

The three terms are - 2, 4, 10.

Answer:

-1

Step-by-step explanation:

To find the slope given two points use the formula

m = ( y2-y1)/(x2-x1)

   = ( 8-2)/(4-10)

    = 6/-6

   = -1

Consider the following equation. 4x + 2 = 8x - 5 Which equation and explanation could represent a step in finding the value of x
Maksim231197 [3]

Answer:

Step-by-step explanation:

Given the expression 4x+2 = 8X-5. To find the value of x, we need to follow the steps;

Sep 1:

Add 5 to both using addition property to move 5 to both sides

4x+2+5= 8x-5+5

4x+7 = 8x

Step 2:

Collect like terms

4x-8x = -7

-4x = -7

Step3:

Divide both sides by -4

-4x-4 = -7/-4

x = 7/4
