Answer:
x=5, y=2
Step-by-step explanation:
To solve this system, we need to find x and y. First, let's find x. In the first equation (6x+4y=42), subtract 4y on both sides to isolate 6x. This will result in 6x=42-4y. Divide by 6 on both sides to isolate x and get x=7-
y. Now we know what x equals. Go to the second equation ad plug this into it. So instead of -3x+3y=-6, you'll have -3(7-y)+3y=-6. Use the distributive property to get -21+2y+3y=-6. Add 2y and 3y to get -21+5y=-6. Add 21 to both sides to isolate 5y and get 5y=15. Divide by 5 on both sides to isolate y and get y=3. Now that we know that y=3, we can plug this back into the equation that was bolded above so that we can find x, so we'll have x=7-(3) since y=3, and we'll get x=7-
, or x=7-2, or x=5.
x=5
y=2
Answer:
Step-by-step explanation:
The equation of a circle is 
where 
is the center of the circle and 
is the radius of the circle.
Given that 
and it passes 
, their distance between each other must the radius of the circle, so we can use the distance formula to find the radius:
Therefore, if the length of the radius is 
units, then 
, making the final equation of the circle
Answer:
3.6
Step-by-step explanation:
sine theta=3.2/5.1
theta=sine^-1(3.2/5.1)
theta=38.86230987
sine 38.86230987=x/5.7
x=sine 38.86230987(5.7)
x=3.576470588
Rounded to the nearest tenth is 3.6
