Your input value set is {-3, -2, 2, 3}.

One by one, subst. the x values into the function and note the y-value obtained.  In which of the four cases does this y-value match the given ordinate?

Example:

Let's try x = -3.  Subst. -3 for x in h(x) = x^2 + 2, we get h(-3) = (-3)^2 + 2, 
or 11.    But the ordered pair is (-3,-7), and -7 is not equal to 11.  Thus, eliminate the first answer choice.  Move on and do the same work for the next x-value, which is x = -2.

Dmitry [639]

Answer:

See below

Step-by-step explanation:

The question is missing information:  " . . . how far would he go in an <u>???"</u>

<u></u>

If the question is how far he would go in a [Pick a despised car model} ?  The answer is still 400.  The car would break down.

If the question is how far would he go in the same amount of time:

Whe the speed limit was 55, it would take Bob (55 miles/hr)*(X hr) = 400 miles

X = 7.273 hours to go 400 miles at 55 mph.

A speed limit of 70 mph would allow Bob the go:

    (70 miles/hour)*(7.272 hours) = 509.1 miles

Solve the inequality:-3x-4/7 &gt;5
Aliun [14]

x < -  \frac{13}{7}

add \frac{4}{7} to both sides

- 3x > \frac{4}{7} + \frac{35}{7}

- 3x > \frac{39}{7} ( divide both sides by - 3 )

note that when we divide/ multiply by a negative quantity we must reverse the inequality symbol

x < - \frac{13}{7}
