Solve using the quadratic equation for all values of x in simplest form answer this

Step-by-step explanation:

simplify both sides of the equation

-x^2+16=-7

subtract 16 form both sides

-x^2= -23

divide by -1

x^2=23

take square root

and your answer is x= plus or minus (square root) of 23 or -23

Step by STEP explanation

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.

step-by-step explanation:

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
