Answer: y = 0.5, x = 50

Step-by-step explanation: Both triangles in the picture are isosceles, telling us that the 2 angles at the bottom are congruent. With this, we can find y by doing the following:

a triangle has 180 degrees so we subtract the given 50 which gives us 130

2(2y + 64) = 130

4y + 128 = 130

y = .5

This means that the bottom 2 angles are both 65. Since the top angle of the second triangle is supplementary to the bottom angle of the first one, the top angle of the second triangle is 115. So, we find x by:

2(45 - x/4) = 65

x = 50

This means the bottom 2 angles of the second triangle are both 32.5.

Answer:

50+2y+64+2y+64=180(<em>being</em><em> </em><em>isosc</em><em>eles</em><em> triangle</em><em>,</em><em>the</em><em> </em><em>base</em><em> </em><em>are</em><em> </em><em>equal</em><em> </em><em>and</em><em> </em><em>its sum </em><em>is</em><em> </em><em>1</em><em>8</em><em>0</em><em>)</em>

<em>1</em><em>7</em><em>8</em><em>+</em><em>4</em><em>y</em><em>=</em><em>1</em><em>8</em><em>0</em>

<em>4</em><em>y</em><em>=</em><em>1</em><em>8</em><em>0</em><em>-</em><em>1</em><em>7</em><em>8</em>

<em>y</em><em>=</em><em>2</em><em>/</em><em>4</em>

<em>y</em><em>=</em><em>1</em><em>/</em><em>2</em><em>,</em><em>,</em>

<em>now</em><em>,</em>

<em>to</em><em> </em><em>find</em><em> </em><em>the</em><em> </em><em>value</em><em> </em><em>of</em><em> </em><em>2</em><em>y</em><em>+</em><em>6</em><em>4</em>

<em>2</em><em>*</em><em>1</em><em>/</em><em>2</em><em>+</em><em>6</em><em>4</em>

<em>1</em><em>+</em><em>6</em><em>4</em>

<em>6</em><em>5</em>

<em>atlast</em><em>,</em>

<em>4</em><em>5</em><em>-</em><em>x</em><em>/</em><em>4</em><em>+</em><em>4</em><em>5</em><em>-</em><em>x</em><em>/</em><em>4</em><em>+</em><em>6</em><em>5</em><em>=</em><em>1</em><em>8</em><em>0</em>

<em>1</em><em>5</em><em>5</em><em>-</em><em>x</em><em>-</em><em>x</em><em>/</em><em>4</em><em>=</em><em>1</em><em>8</em><em>0</em>

<em>now</em><em> </em><em>solve</em><em> </em><em>yoursel</em><em>f</em><em> </em><em>and</em><em> </em><em>what</em><em> </em><em>valve</em><em> </em><em>comes</em><em> </em><em>that's </em><em>the</em><em> </em><em>value</em><em> </em><em>of</em><em> </em><em>X.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em>

1. IF the function f(x) = 2(x – 3)2 – 4 is shifted vertically three units up and horizontally
hichkok12 [17]

Answer:

I believe it is 2(x-5)²−1

Step-by-step explanation:

The parentheses represent the horizontal shift. (X-__) is a shift to the right. (X+__) is a shift to the left. The last number of the function is the vertical shift. A negative number is shifting down and a post number is shifting up.

So, if the graph shifts up three units, then you add 3 + -4 to get -1. And if the graph shifts right 2 units, then you subtract 2 from -3 to get -5.
