Answer:

A) Protractor

Step-by-step explanation:

In Mathematics, geometric constructions refers to the drawing of geometric shapes, lines and angles with the exclusive aid of a pencil, straightedge/ruler and a pair of compass.

The pencil is the major drawing tool during the construction while the pair of compass and straightedge are used to construct arcs/circles and straight lines respectively. Note that, a PROTRACTOR is not needed in a geometric construction because length or angle measurements are prohibited.

Determine if each fraction is a terminating decimal or a repeating decimal. Write each fraction in the correct box.

Alja [10]

-7/9 is repeating
42/50 is terminating
-1/125 is terminating
-77/600 is repeating
179/200 is terminating
5/11 is terminating

The way to figure this out is just by dividing the Numerator (top number) by the denomiter (bottom number)
Example 5÷11=.45454545 repeating

Arkadaşlar soruyu bulabilirmisiniz 28=50-4n

andrew11 [14]

Answer:

The answer is 8 because 28=50- 4n we have to group like terms so 28- 50= -4n therefore 28-50 will be -32 = -4n therefore we have to divide both side by the coefficient of n that is -4 and minus 4 goes to itself 1 and to - 32 8 because the minus sign will cancel the minus

Describe how you would graph a figure that is translated by (x - 4,4+2).

atroni [7]

Answer:

see explanation

Step-by-step explanation:

Given the translation rule

(x, y ) → (x - 4, y + 2 )

This means subtract 4 from the original x- coordinate and add 2 to the original y- coordinate, that is

a point (4 , - 4 ) → (4 - 4, - 4 + 2 ) → (0, - 2 )

Which expression gives the x-coordinate of the solution of the system?

aalyn [17]

To find the the expression that gives the value of $x$ we are going to proceed as follows:
$5x+3y=-18$ equation (1)
$2x-4y=-28$ equation (1)

Step 1. solve for $y$ in equation (2)
$2x-4y=-28$
$-4y=-28-2x$
$y= \frac{-28-2x}{-4}$
$y=7+ \frac{1}{2} x$ equation (3)

Step 3. Replace equation (3) in equation (1) and solve for $x$
$5x+3y=-18$
$5x+3(7+ \frac{1}{2} x)=-18$
$5x+21+ \frac{3}{2} x=-18$
$\frac{13}{2} x=-39$
$x= \frac{-39(2)}{(13)}$
$x=-6$

We can conclude that the expression that gives the value of $x$ is: $x=-6$
