C. The cost of 5 notebooks is less than the cost of 3 + a $2 pen.

Process of elimination:
The greater or less than sign is open towards 3x + 2.

Get rid of the ones that say 5x is greater .

So A. And D. Are not an option

Now you have to put the pieces together.

Answer B. Sounds right until you get to the “$2-off coupon”

In the equation above it says 3x PLUS 2.
$2 off means subtraction. So we automatically know C is the only other answer.

Harlon recorded this set of data, which contains an outlier. 163, 97, 184, 199, 169, 175 What is the range of this set of data?

Hey there!

To find the range, first put the numbers in order from smallest to largest.
97, 163, 169, 175, 184, 199

Then take the largest number, 199, and subtract the smallest number (in this case, the outlier) which is 97.

199-97=102

each of equal sides of an isosceles triangle is 4cm greater than its height .If the base of triangle is 24 cm ,calculate the per

Montano1993 [528]

<h3>Answer:-</h3>

192 cm²

<h3>Step by step explanation :-</h3>

Let us take the height be x , then its side = x + 4. Now half of base will be 12 cm .

According to Pythagoras Theorem :-

=> base² + perpendicular ² = hypontenuse ²

=> 12² + x² = (x+4)²

=> 144 + x² = x² + 16 + 8x

=> 8x = 144-16

=> 8x = 128

=> x = 128/8

=> x = 16 cm .

Hence the height of ∆ is 16 cm .So the area will be half the product of base and altitude.

= 1/2 * 16 cm * 24cm .

= 192 cm²

<h3>★ Hence the area of the triangle is 192 cm² .</h3>

Gemiola [76]

Answer:

C.) y is greater than or equal to -6

Step-by-step explanation:

The range are all the set of y-values that are plotted on the vertical axis (y-axis).

The range starts from -6 and above. Which is y ≥ -6

Therefore, range of the function is said to be:

C.) y is greater than or equal to -6
