Let

If M is the midpoint, the x and y coordinates of M are the average of the x and y coordinates of P and Q:

We can solve this expression for the coordinates of Q:


Plug in the values for the coordinates of M and P to get


Answer:
49x^2 - 9 = 0As there is no x term, we can pretty much guess we have a situation where we factlrise by something known aa difference of two squares, so to factorise it:49 = 7^29 = 3^2x^2 = (x)^2so...(7x - 3)(7x + 3) = 07x - 3 = 0 7x + 3 = 0x = 3/7 x = -3/7
Step-by-step explanation:
It is a good idea to check to see if your answer is reasonable because a. if your answer is reasonable, you have probably done the problem correctly.
144 inches. 12 feet in one hour
12 inches per feet
12feet x 12 inches per foot= 144 inches
Let's solve your equation step-by-step.
−7x=−2x2+15
Step 1: Subtract -2x^2+15 from both sides.
−7x−(−2x2+15)=−2x2+15−(−2x2+15)
2x2−7x−15=0
Step 2: Factor left side of equation.
(2x+3)(x−5)=0
Step 3: Set factors equal to 0.
2x+3=0 or x−5=0
x=
or x=5
Answer:
x=
or x=5
Hope this helps
