5x+3y=9
2x-3y=5
5x+2x=9+5
7x=14
14/7x= 2
x=2
sub it in so you get y
5(2)+3y=9
10+3y=9 (-10 to get rid of it)
3y=-1
3y/-1= - 1/3
x= 2 y= - 1/3
Tanα=y/x
x=y/tanα, we are told that y=93m and α=26.3°
x=93/tan26.3 m
x≈188m (to nearest whole meter)
Answer:
John- 375
Karen- 125
Step-by-step explanation:
Answer 1...
j =3k
2j + k = 875
substituting the first eqn into the 2nd
2(3k) + k = 875
6k+ k =875
7k = 875
k =875/7 =125
thus j = 3(125) =375
Answer:
32 days is my final answer
Step-by-step explanation:
Answer:
When a point is reflected across the y-axis, the y-coordinate(s) remain the same. But the x-coordinate(s) is transformed into opposite signs.
