Answers:

  • Domain is (-4, 3]
  • Range is (-5, 5]

=====================================================

Explanation:

The domain is the set of allowed x input values, aka the set of all allowed x coordinates of the points. We see that -4 < x \le 3. It might help to draw vertical lines through the endpoints until you reach the x axis. Note the open hole at x = -4 to indicate we do not include this as part of the domain (hence the lack of "or equal to" for the first inequality sign).

The interval -4 < x \le 3 then can be condensed into the shorthand form (-4, 3] which is the domain in interval notation.

It says: x is between -4 and 3. It can't equal -4 but it can equal 3.

So the use of parenthesis versus square brackets tells the reader which endpoint is included or not.

--------------------------------------------------

The range describes all possible y outputs. We see that y = 5 is the largest it gets and y = -5 is the lower bound. It might help to draw horizontal lines through the endpoints until you reach the y axis. The open hole means -5 is not part of the range.

The range as a compound inequality is -5 < y \le 5. This condenses into the shorthand of (-5, 5] which is the range in interval notation.

Verbally, the range is the set of y values such that y is between -5 and 5. It can't equal -5 but it can equal 5.

Sila jogged 12 kilometers today and wants to know how far she traveled in feet. What error did Sila make while converting from k
elena-14-01-66 [18.8K]

Answer:

sila put a wrong number in her calculator when multiplying the numerators

Step-by-step explanation:

Sila jogged 12 kilometers today and wants to know how far she traveled in feet. what error did sila make while converting from kilometers to feet?

StartFraction 12 kilometers Over 1 EndFraction times StartFraction 0.62 miles Over 1 kilometer EndFraction times StartFraction 5280 feet Over 1 mile EndFraction = 392,832 feet

sila put a wrong number in her calculator when multiplying the numerators.

1 km sila's first fraction should be 0 62 mi 1 mi

sila's last fraction should be 5280 ft

sila forgot to divide by 0 62 asap

(12kilometers / 1 ) × (0.62 miles / 1 kilometer) × 5280 / 1 mile

12 kilometers = 39,370.079 feet

1 kilometer = 0.621 miles

sila put a wrong number in her calculator when multiplying the numerators

If (4,y) is a solution to x-2y = 6, what is the value of y?
frutty [35]

Answer:

(4, -1)

Step-by-step explanation:

(4, y) is a solution to x - 2y = 6.

Find the value of y:

4-2y=6\\\\4-4-2y=6-4\\\\-2y=2\\\\\frac{-2y=2}{-2}\\\\\boxed{y=-1}

The value of y is '-1'.

(4, -1) is a solution to the equation.

Hope this helps.
