Find miles per hour by dividing total miles by total time:

408 / 6 = 68 miles per hour

Now multiply miles per hour by time:

68 x 4 1/2 = 306 miles

Answer: 306 miles

Write an absolute value function that shifted 2 units right. HELPPPP

iVinArrow [24]

Answer: (a)

Step-by-step explanation:

Suppose the original function is $y=\left | x \right |$

To shift it 2 units right, replace x by x-2 such that

$\Rightarrow x-2=0\\\Rightarrow x=2$

So, the function becomes $y=\left | x -2\right |$

What is the sum of the first 47 terms of the sequence? -215, -201, -187, -173, ...

Andru [333]

Answer:

5029

Step-by-step explanation:

There is a common difference between consecutive terms, that is

d = - 201 - (- 215) = - 187 - (- 201) = - 173 - (- 187) = 14

This indicates the sequence is arithmetic with sum to n term

= [ 2a₁ + (n - 1)d ]

where a₁ is the first term and d the common difference

Here a₁ = - 215 and d = 14 , then

= [ (2 × - 215) + (46 × 14) ]

= 23.5 (- 430 + 644)

= 23.5 × 214

= 5029

Given three consecutive integers with a sum of four times the second number, write an algebraic equation for this situation

Black_prince [1.1K]

Define x:

Let the first number be x.

1st number = x
2nd number = x + 1
3rd number = x + 2

Construct equation:
x + x + 1 + x + 2 = 4(x + 1)
3x + 3 = 4(x + 1)

Answer: 3x + 3 = 4(x + 1)
