10sinx-6=0
sinx=6/10=3/5, not negative three out of five.
yo use a calculator' sin3/5=sin0.6, if 0≤x≤2π, x≈37 or 127 (37+90=127, sine is positive in first and second quadrant)
Answer:
y=4
Step-by-step explanation:
Let's solve your system by substitution.
x+y=7;x+2y=11
Step: Solve x+y=7 for x:
x+y=7
x+y+−y=7+−y(Add -y to both sides)
x=−y+7
Step: Substitute−y+7forxinx+2y=11:
x+2y=11
−y+7+2y=11
y+7=11(Simplify both sides of the equation)
y+7+−7=11+−7(Add -7 to both sides)
y=4
Step: Substitute 4 for y in x=−y+7:
x=−y+7
x=−4+7
x=3(Simplify both sides of the equation)
Answer:
x=3 and y=4

Answer:
0.5 seconds
Step-by-step explanation:
Two rockets are launched at the same time, but from different heights.
when the heights are same then y are equal. So equation both equations and solve for t
Add -16t^2 on both sides
Subtract 150 t from both sides
Divide 10 on both sides
t=0.5 seconds
