Refer the diagram at the right. identify each angle pair as adjacent, vertical, or neither 7-12

Oxana [17]

Adjacent angles are angles that are side by side (right next to each other). They share a side. #7 and 11 are pairs of adjacent angles.

Vertical angles are angles that are directly across from each other. They are the same angle. #8 and 9 are vertical angles.

#10 and 12 do not fit either of these descriptions so they are neither.

Write the coordinate of the intercept

Basile [38]

Answer:

m = 2/3

y-intercept: 2

Explanation:

First convert this equation into standard form by distributing the 6y and -4x from the coefficient of 2, and then putting the variables in order.

This equation should be in the form: Ax + By = C (Standard form)

y = -Ax/B + C/B : y = mx + b (Slope intercept form)

2(6y - 4x) = 24 → 12y - 8x = 24

→ -8x + 12y = 24 → -8x = -12y + 24 → 8x = 12y - 24 → 8x - 12y = -24

8x - 12y = -24

A B C

Once you have standard form, you are ready to convert this into slope intercept by isolating the y completely.

8x - 12y = -24

-8x -8x

(First through the subtraction property of equality, remove 8x from both sides so that -12y is by itself on the left)

-12y = -8x - 24

×-1 ×-1 ×-1

(Through the identity property of negative 1, remove the negative sign from all of the numbers because a negative times a negative is a positive)

12y = 8x + 24

(Lastly, through the division property of equality, divide all sides by 12 because it is the coefficient of y, which will solve for the variable)

In my friend's coin purse, I found 12 pennies. The ages, in years, of the pennies obtained by subtracting the year stamped on th

Arlecino [84]

Answer: mean = 10.3 and median = 9.5

Step-by-step explanation:

Given data :

22, 14, 8, 1, 9, 0, 31, 2, 13, 3, 11, 10

Mean = $\dfrac{\text{Sum of all data values}}{\text{No. of data values}}$

$=\dfrac{22+14+8+1+9+0+31+2+13+3+11+10}{12}$

$=\dfrac{124}{12}=10.3$

Median = Middle most value.

For Median , we first arrange the data values in an order.

0 , 1 , 2, 3, 8, 9, 10 , 11, 13 , 14, 22, 31

Since , number of data values is 12 ( even) , so the median would be the mean of the two middlemost value.

i.e . Median= $\dfrac{9+10}{2}=9.5$

Hence, the mean and median of this distribution (in years) are :

mean = 10.3 and median = 9.5

Tell whether ΔABC and ΔDCB can be proven congruent.

Vikentia [17]

Answer:

D. No, there isn’t enough information because only two pairs of corresponding sides can't be used to prove that two triangles are congruent.
