Answer:
(1,2) is a solution to both equations
Step-by-step explanation:
To determine if (1,2) is a solution to both equations, substitute into the equation and see if it is true
2x+y =4
2(1) + 2 =4
2+2 =4
4=4
true
y =3x-1
2 = 3(1) -1
2 =3-1
2=2
true
Since both statements are true
(1,2) is a solution to both equations
If two angles are complementary, the sum of their measures is 90 degrees. Call one of the angles x. This means that its complement is 90 - x degrees. But the difference in their measures is 12 degrees.
18×3=54
3.99×2=7.98
54+7.98+45=106.98
106.98×.085=9.0933
106.98+9.0933=116.0733
rounded to 116.07
answer 116.07
X = sqrt((5 + 6)^2 - 5^2) = sqrt(11^2 - 5^2) = sqrt(121 - 25) = sqrt(96) = 9.8
