The third number is 22
Explanation: If you multiply 10 by 2 you get 20 and if you multiply 10 by 3 you get 30. Add those together and you get 50. Then you subtract 50 from 72 and you would get 22... I hoped this helped!

HELP !! The figure below is made from a rectangle and a triangle use the measurements shown below , find the area of the figure

Vika [28.1K]

The answer is 76. multiply 15 times 4 which is 60.
and the triangle is the difference of the sides, so 19-15=4.
so then multiply the base and height, this leaves 4x4 which is 16.
then add the two. 60+ 16= 76

Answer:

121.21 people per square mile

Step-by-step explanation:

area = 1/2(12 + 21)(14) = 231 mi²

28,000/231 = 121.21 people per square mile

Find the slope and the y-intercept of the of the linear equation.<br><br> 0=2-3y+12x

andrew11 [14]

The slope is 4 and the y-intercept is $\frac{2}{3}$

Step-by-step explanation:

The general form of a linear equation is Ax + By + C = 0, where

A is the coefficient of x
B is the coefficient of y
C is the numerical term
A, B, and C are integers
The slope of the line = $\frac{-A}{B}$
The y-intercept = $\frac{-C}{B}$

∵ The linear equation is 0 = 2 - 3y + 12x

- Switch the two sides and arrange the terms as the general

form above

∴ 12x - 3y + 3 = 0

∴ A = 12

∴ B = -3

∴ C = 2

∵ The slope of the line = $\frac{-A}{B}$

- Substitute A by 12 and B by -3

∴ The slope of the line = $\frac{-12}{-3}$

∴ The slope of the line = 4

∵ The y-intercept = $\frac{-C}{B}$

- Substitute C by 2 and B by -3

∴ The y-intercept = $\frac{-2}{-3}$

∴ The y-intercept = $\frac{2}{3}$

The slope is 4 and the y-intercept is $\frac{2}{3}$

Using symmetry concepts, it is found that there is a line of symmetry at x = 50, option D.

A line symmetry is an imaginary line that runs through a graph, dividing it into two equal parts.
A point symmetry is when every point is equidistant to the line of symmetry, but in opposite directions.

In this problem, the values of x range from 0 to 100, being divided(definition changed) at 50, thus, there is a line of symmetry at x = 50, and option D is the correct one.
