EXPLAIN WHY THE SYSTEM HAS THE ANSWER GIVEN. SOLVE EACH SYSTEM BY ELIMINATION TO PROVE YOUR ANSWER.
Aleonysh [2.5K]

Answer:

Step-by-step explanation:

The given system of equations is expressed as

3x + y = 9 - - - - - - - - - - - - - - -1

3x = 9 - y - - - - - - - - - - - - - -2

To apply the method of elimination, we would rearrange equation 2 so that it would take the form of equation 1. Therefore, we would add y to the left hand side and the right hand side of the equation, it becomes

3x + y = 9 - - - - - - - - - - - - - - - - -3

Subtracting equation 3 from equation 1, it becomes

0 = 0

The equations have infinitely many solutions because if we input any values of x and y that satisfies the first equation, those values will also satisfy the second equation.

Ronch [10]
\frac{9}{36}=\\\\\frac{9:3}{36:3}=\boxed{\frac{3}{12}}\\\\\frac{9:9}{36:9}=\boxed{\frac{1}{4}}\\\\therefore\ \frac{9}{36}=\frac{1}{4}\\\\so,\ next\ equivalent\ fractions\ are:\\\\\frac{1\cdot2}{4\cdot2}=\boxed{\frac{2}{8}}\\\\\frac{1\cdot4}{4\cdot4}=\boxed{\frac{4}{16}}\\\\\frac{1\cdot5}{4\cdot5}=\boxed{\frac{5}{20}}\\\vdots\\and\ an\ infinite\ number\ of\ other

fenix001 [56]

Answer:

250 degrees

Step-by-step explanation:

The arc intercepted by the angle formed by a secant and a tangent is twice the measure of the angle. See the attached image.  The intercepted arc measures 110 degrees.

x is the measure of the rest of the circle, so it is 360 - 110 = 250 degrees.
