x + 2y + 3 = 0
Subtract x from both sides.
2y + 3 = -x
Subtract 3 from both sides.
2y = -x - 3
Divide by 2 on both sides
y = -(x+3)/2
x + y + 4 = 0
Subtract x and 4 from both sides
y = -x - 4
3x - 2y + 4 = 0
Subtract 3x and 4 from both sides.
-2y = -3x -4
Divide by -2 from both sides.
y = -(3x + 4) / 2
The answer is the graph that contains these slopes and lines on the graph, which was not provided.
Answer:(2/3) + (9/10) = 47/30
= 1 17/30
Step-by-step explanation:
2a. speed= distance
---------------
time
60÷69 = 52.1739 miles per hour.
so for the next one with the airplane flies 296 km in 276 min is the same formula.
296/276 = 39.9839 mph.
I couldn't see the first question clear...sorry but apply same formula.
Hoping this will help you
Answer:
is a way to express the definition of a circle on the coordinate plane.
Step-by-step explanation:
We know that the general equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius. So add 21 to both sides to get the constant term to the righthand side of the equation. Then complete the square for the y terms.
You can't, it has been done before but there is a fault in the working because the 2 numbers are different. If you want to see a video of someone attempt it, I believe there is a video on the numberphile channel.
Hope this helps :)
