If signs are different you subtract. So 2.5- -1.25 equals 1.25 and keep the sign of the biggest number

Number the tables as follows:

1  2
3  4

Eliminate 3 and 4 immediately, because for x = 2 the y values are wrong (3 and 1).

In tables 1 and 2, the input (1) produces the correct output (-1).

So we have to determine which table agrees 100% with the system of equations given.

Comparing tables 1 and 2, row by row, we see that their contents are the same EXCEPT for the first rows.  So focus on determing which of those 2 rows displays values that satisfy both given equations.

First I looked at y=2x-5, and subst. -1 for x.  I got -7, which is correct in table 1 but not in table 2 (where the value would be -13).

Thus, table 1 correct represents the solution of the system of equations.

Using distributive property -1/6(6y+7)??
Solnce55 [7]

Hello!

The distributive property states, a(b + c) = ab + ac. Normally, we would simplify the values inside the parentheses first, and then multiply, but since these two values are not alike terms, we would need to use the distributive property.

-1/6(6y + 7) is also equal to -1/6(6y) + -1/6(7), so with that, we can simplify the expression.

-1/6(6y) + -1/6(7) can be simplified to -y + -7/6.

Therefore, using the distributive property, the answer is -y - 7/6.

Given the regular octagon shown below, what is the measure of angle x?
vladimir1956 [14]

Answer:

x=45°

Step-by-step explanation:

The angle shown in the figure is known as an external angle.

Also, <u>in a regular polygon (like the regular octagon) the sum of all the exterior angles is the same regardless of the number of sides of the figure</u>:

360°

And to find the measure of a single external angle (such as the angle x shown in the figure) we must <u>divide 360 ° by the number of sides n:</u>

\frac{360}{n}

and for the regular octagon, since it has 8 sides:

n=8

so the value of x is:

x=\frac{360}{n}\\ \\x=\frac{360}{8}\\ \\x=45°

the measure of angle x is 45° which is the second option
