Answer:

- 7/9

Step-by-step explanation:

-4/9 + (-1/3)

= -(4/9) - (1/3)

= - (4/9 + 1/3)

= - (4/9 + 3/9)

= - [(4 + 3) / 9 ]

Which triangle is ​△MNO​ similar to and why? △MNO is similar to △GHK by ​ AA Similarity Postulate ​. ​△MNO​ is similar to △DEF b
andrew11 [14]
<span>MNO is similar to GHK by AA Similarity Postulate

   Let's start by listing each triangle and the measurements of all three angles. For each triangle, we've been given the measurements of 2 of the angles and the 3 angle will simply be 180 minus the other 2 angles. I assume you can do the subtraction, so I'll simply list each triangle with all three angle measurements.
 NMO: 79, 22, 79
 GHK: 79, 79, 22
 PQR: 20, 79, 81
 DEF: 82, 22, 76
   And the triangles NMO and GHK are similar to each other since they have the same angles. The order really doesn't matter since it's OK for similar triangles to be rotated or reflected. The key thing to remember in a triangle is that if you've been told what 2 of the angles are, you also know what the 3rd angle is since the sum of the angles of a triangle will always be 180.
So the answer is:
 MNO is similar to GHK by AA Similarity Postulate"</span>

Which equation shows the relationship in the table below X 3, 5, 8, 11 Y 7 ,11, 17, 23 a y=2xb y=x+4 c y=2x+1 d y=2x+4
ladessa [460]

ANSWER

c)\text{ }y=2x+1

EXPLANATION

We want to find the equation for the relationship shown in the table.

The relationship shown in the table represents a linear relationship. The general form of a linear equation is:

y=mx+b

where m = slope

b = y-intercept

To find the slope of the equation, apply the formula:

m=\frac{y_2-y_1}{x_2-x_1}

where (x1, y1) and (x2, y2) are two sets of values from the table.

Let us take (3, 7) and (5, 11) as (x1, y1) and (x2, y2)

Hence, the slope of the equation is:

\begin{gathered} m=\frac{11-7}{5-3}=\frac{4}{2} \\ m=2 \end{gathered}

Now, to find the equation of the line, apply the point-slope method:

y-y_1=m(x-x_1)

Therefore, the equation that shows the relationship in the table is:

\begin{gathered} y-7=2(x-3) \\ y-7=2x-6 \\ y=2x-6+7 \\ y=2x+1 \end{gathered}

The correct option is option C.
