<u>X AND Y INTERCEPTS</u>
1st Answer:
x = 9
Step-by-step explanation:
<u>first you want to substitute the y</u>
<h3>
0 = -2 √(25 - x + 8)</h3>
<u>move the expression to the left</u>
<h3>
2 √(25 - x) = 8</h3>
<u>divide both sides</u>
<h3>√25 - x + 4</h3>
<u>move the constant to the right</u>
<h3>
25 - x = 16</h3>
<u>calculate</u>
<h3>
-x = -9</h3>
<u>change the signs</u>
<h3>
x = 9</h3><h3>
</h3>
2nd Answer:
x = -65/9 OR x = - 7 2/9, x = - 7.2
Step-by-step explanation:
<u>first you want to substitute the y</u>
<h2>
0 = -3 √(x + 9) = 4</h2>
<u>move the expression to the left</u>
<h2>
3√(x+9) = 4</h2>
<u>divide both sides</u>
<h2>
√(x+9) = 4/3</h2>
<u>move the constant to the right</u>
<h2>
x = 16/9 - 9</h2>
<u>calculate</u>
<h2>
x = -65/9</h2>

Answer:
253°
Step-by-step explanation:
The central angle whose rays intercept a diameter of the circle has measure 180 deg.
m<AOD = 73 deg
m<DOB = 180 deg
m<ADB = m<AOD +m<DOB = 73 deg + 180 deg = 253 deg
The measure of an arc of a circle is equal to the measure of the central angle that subtends it.
m(arc)AOD = m<AOD = 253 deg
Answer: 253°
The answer is x^2/3y^3 hopefully this is correct
