Using the image given, the angles that are Alternate Exterior Angles are: 1, 2, 3, 4,13,14, 18, 19.

<h3>What are Alternate Exterior Angles?</h3>

These are known to be the Alternate exterior angles that are regarded as the pair of angles found on the outer side of the two parallel lines but they are seen on the opposite side of the transversal.

Note that in the image given, there are two parallel lines and two transversal lines.

Note also that to get the Alternate exterior angles, it has to be the angles seen on the seen on the opposite side of the transversal that has crossed the parallels lines and from the image given, only angle 1, 2, 3, 4,13,14, 18, 19 fit into the description.

Therefore, Using the image given, the angles that are Alternate Exterior Angles are: 1, 2, 3, 4,13,14, 18 19.

My calculator does not have a 3 key that works! How can I use this broken calculator to do 23 x 45.

erik [133]

<h3><u>Solution:-</u></h3>

$\longrightarrow$ This problem can be tackled by using distributive property of multiplication .

It states for any three numbers a,b and c

$\green{ \underline { \boxed{ \sf{(a±b)\times c = a \times c±b\times c}}}}$

<u>Similarly</u>,

$\quad$ 23 × 45

$\longrightarrow$ (21+2) ×45

$\longrightarrow$ 21×45+2×45

$\longrightarrow$ 945 + 90

$\longrightarrow$ 1035

It can also be done as-

$\quad$ 23 × 45

$\longrightarrow$ (25-2) ×45

$\longrightarrow$ 25×45-2×45

$\longrightarrow$ 1125-90

$\longrightarrow$ 1035

Which steps should be used to graph the equation y – 4 = y minus 4 equals StartFraction one-third EndFraction left-parenthesis x

dalvyx [7]

Answer:

The steps are are explained below.

Step-by-step explanation:

Given:

The equation of the line is given as:

$y-4=\frac{1}{3}(x+2)$

The above equation is in point-slope form $y-y_1=m(x-x_1)$ .

Therefore, on comparing, we get

$x_1=-2,y_1=4,m=\frac{1}{3}$

So, the slope is one-third and point is (-2,4).

Now, following are steps for plotting the graph:

i. Plot the point (-2,4).

ii. Since the slope is one-third, it means we need to move 3 units to right from the point (-2,4) and then 1 unit up. So, after translating 3 units right and 1 unit up we mark the second point which is $(-2+3,4+1)\rightarrow )(1,5)$ .
