the circle below has center T. suppose that m UV = 138 degrees and that UW is tangent to the circle at U. find the following

alisha [4.7K]

Angle UTV is basically given: it's 138°.

Moreover, since UTV is isosceles, the other two angles have the same measure x. We thus have

$138+x+x=180 \iff 2x=42 \iff x=21$

So, TUV is 21°, and VUW is complementary, so it must be 69° so that they sum up to 90°

Translate into an inequality: The sum of 2 consecutive integers is at most the difference between nine times the smaller and 5

mariarad [96]

The answer is b. "at most" means that x + (x + 1) must be smaller than or equal to the other side of the equation.

Write an equation that is perpendicular to 3x - 6y=1 and contains the points (-3,7)

zmey [24]

$(-3,7), \ \ \ 3x - 6y = 1 \ subtract \ (-3x) \ from \ each \ side \\ \\ -6y = -3x + 1 \ divide \ each \term \ by \ (-6) \\ \\ y = \frac{3} {6}x - \frac{1}{6}\\ \\ y = \frac{1} {2}x - \frac{1}{6}\\ \\ The \ slope \ is :m _{1} = \frac{1}{2} \\ \\ If \ m_{1} \ and \ m _{2} \ are \ the \ gradients \ of \ two \ perpendicular \\ \\ lines \ we \ have \ m _{1}*m _{2} = -1 \\\\\frac{1}{2}*m_{2}=-1
$

$\frac{1}{2}*m_{2}=-1\ \ | \ multiply\ both\ sides\ by\ 2 \\\\m_{2}=-2 \\\\ Now \ your \ equation \ of \ line \ passing \ through \ (-3,7) would \ be: \\ \\ y=m_{2}x+b \\ \\7=(-2} )\cdot (-3) + b \\ \\ 7=6+b\\ \\ b=7-6\\ \\b=1 \\ \\ y =-2x +1$
