Answer:
Step-by-step explanation:
well the mean is adding all the numbers up and divide them by how many different numbers there are for example 7 9 18 41 9, first you would add them all together 41+18=59 59+(9+9) well 9+9=18 so 59+18=77 77+7=84 we're done with the First part, now we divide it by the number of different numbers that are shown, which is 5, so it's 84 divided by 5 which gives you the answer of 16.8
<h3>Option B</h3><h3>Multiply first equation by -2 and second equation by 3, solution (1, 1)</h3>
<em><u>Solution:</u></em>
<em><u>Given system of equations are:</u></em>
3x - 5y = -2 -------- eqn 1
2x + y = 3 ------- eqn 2
We have to solve the system of equations
Multiply eqn 1 by -2
-6x + 10y = 4 ------- eqn 3
Multiply eqn 2 by 3
6x + 3y = 9 -------- eqn 4
Add eqn 3 and eqn 4
-6x + 10y = 4
6x + 3y = 9
( + ) ------------
13y = 13
y = 1
Substitute y = 1 in eqn 2
2x + 1 = 3
2x = 2
x = 1
Thus solution is (1, 1)
Thus option B is correct
A secant is a line that intersects a circle in exactly two points. When a tangent and a secant, two secants, or two tangents intersect outside a circle than the measure of the angle is formed is one-half the positive difference of the measures of the intercepted arcs.
