Assume that children is an integer variable containing the number of children in a community and that families is an integer var
kherson [118]

Answer:

Answered

Step-by-step explanation:

Children*1 d/ family

Integer division returns an integer value in most languages.

I am assuming "1d" is double precision 1, which turns the expression into floating point division, thus allowing an answer like 1.8.

it can also be written as

Write an equation in slope-intercept form for the graph shown. (1,0) (0,-2)
AlladinOne [14]

Answer:

y= 2x -2

Step-by-step explanation:

<u>Slope-intercept </u><u>form</u>

y= mx +c, where m is the slope and c is they y-intercept

\textcolor{violet}{\text{\textcircled{1} Find the slope}}

\boxed{ slope = \frac{y _{1} - y_2 }{x_1 - x_2} }

slope =  \frac{0 - ( - 2)}{1 - 0}

slope =  \frac{0 + 2}{1}

slope= 2

\textcolor{violet}{\text{\textcircled{2} \text{Substitute value of slope into m}}}

y= 2x +c

\textcolor{violet}{\text{\textcircled{3} Find c}}

Given that the y-intercept occurs at (0, -2), c= -2.

\textcolor{violet}{\text{\textcircled{4} Substitute the value of c into the equation}}

y= 2x -2

In order for the parallelogram to be a square, x=?
vichka [17]

Answer:

x=7   Thx pls mark as brainliest

Step-by-step explanation:

In order for a polygon to be a parallelogram, the polygon needs to be a four-sided rectangle type shape, with two sets of parallel sides.

For this square to be a parallelogram, all  

4

angles need to be  

90

º

. This will give us to the two sets of parallel sides.

Knowing this, and the fact that on of the angles is being bisected, we need only multiply the defined angle by two and set it equal to  

90

.
