Answer:
x = 55
y = 60
Step-by-step explanation:
If a quadrilateral is inscribed in a circle, then its opposite angles are supplementary. So E and G are supplementary, and H and F are supplementary.
x + 15 + 2x = 180
3x + 15 = 180 combine like terms
3x = 165 subtract 15 from both sides
x = 55 divide both sides by 3
y + 3y - 60 = 180
4y - 60 = 180 combine like terms
4y = 240 subtract 60 from both sides
y = 60 divide both sides by 4
Answer:
y = (x +2)(x -1)(x -3)
Step-by-step explanation:
For each x-intercept (r) the corresponding factor is (x -r). For x-intercepts -2, 1, 3, the factors are ... (x+2), (x-1), (x-3). Then the equation is ...
y = (x +2)(x -1)(x -3)
Answer:
29: 7
Step-by-step explanation:

<em>Cross</em><em> </em><em>multiply</em><em>:</em>

<em>Expand</em><em> </em><em>bracket</em><em>:</em>

<em>Bring</em><em> </em><em>x</em><em> </em><em>terms</em><em> </em><em>to</em><em> </em><em>1</em><em> </em><em>side</em><em>,</em><em> </em><em>y</em><em> </em><em>terms</em><em> </em><em>to</em><em> </em><em>the</em><em> </em><em>other</em><em>:</em>

<em>Simplify</em><em>:</em>
<em>
</em>
<em>Divide</em><em> </em><em>by</em><em> </em><em>7</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>

<em>Divide</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>by</em><em> </em><em>y</em><em>:</em>
<em>
</em>
∴ The ratio of x to y is 29:7.
Answer:
A
Step-by-step explanation:
(3.1)2 is the same thing as 3.1x2. So all you have to do is double 3.1 which is 6.2.
3.angleB is congruent to angle F
4. The slope is -3 and the yintercept is 4
