A student finds the slope of the line between (14, 1) and (18, 17). She writes . What mistake did she make? She mixed up the x-

and y-values. She used y-values where she should have used x-values. She did not keep the order of the points the same in the numerator and the denominator. She should have added the values, not subtracted them.

Samiya bought a tree 3 inches long. Each year, the tree expected to grow 5 inches. How long (How many years) it takes the tree t
Vinil7 [7]

Answer:

19 years

Step-by-step explanation:

Initial height of tree when Samiya bought the tree = 3 inches

Growth in the height of tree every year = 5 inches

Number of years = y

Growth in the height of tree in y years = 5 inches multiplied by number of years

Growth in the height of tree in y years = 5y inches

To find:

Number of years taken by the tree to be 8 ft or 96 inches.

Solution:

The equation for height of tree after y years can be written as:

3 + 5y which is to be compared with 96 inches.

Therefore, the equation is:

3 + 5y = 96\\\Rightarrow 5y=93\\\Rightarrow y \approx 19

Therefore, it will take <em>19 years</em> for the tree to reach a height of 96 inches.

Name a polygon that would have a
liubo4ka [24]

Answer:

The polygon has 43 sides . The polygon can be called 43 - gon or tetracontakaitrigon.

Step-by-step explanation:

In a regular polygon all the sides are equal and also all the angles are equal. The sum of the interior angle of a polygon can be calculated with the following formula;

sum of interior angle = (n−2) × 180°

where

n = number of sides

The sum of the interior angle should be less than 7500 and greater than 7201.

sum of interior angle = (n−2) × 180°

less than 7500 and greater than 7201 = (43 - 2) × 180

less than 7500 and greater than 7201 = 41 × 180

less than 7500 and greater than 7201 = 7380 °

The polygon has 43 sides . The polygon can be called 43 - gon or tetracontakaitrigon.

UNO [17]

Answer:

<em>2 solutions</em>

Step-by-step explanation:

Given the expression

2m/2m+3 - 2m/2m-3 = 1

Find the LCM of the expression at the left hand side:

2m(2m-3)-2m(2m+3)/(2m+3)(2m-3) = 1

open the bracket

4m²-6m-4m²-6m/(4m²-9) = 1

Cross multiply

4m²-6m-4m²-6m = 4m²  - 9

-12m = 4m²  - 9

4m²  - 9+12m = 0

4m² +12m-9 = 0

<em>Since the resulting equation is a quadratic equation, it will have 2 solutions since the degree of the equation is 2</em>
