Answer:
B
Step-by-step explanation:
eliminating systematic measurement errors caused by errors in the measuring instrument used to compare the quantity being measured with a standard.
The elimination method is the process of solving the system of equations, by cancelling unknowns in the system. This makes more simple to solve and easy to solve for the resting unknowns.
Equation solving. A solution is an assignment of expressions to the unknown variables that makes the equality in the equation true. In other words, a solution is an expression or a collection of expressions (one for each unknown) such that, when substituted for the unknowns, the equation becomes an identity .
Answer:
x = 5 or x = -5
Step-by-step explanation:
x^2−9=16
Add 9 to both sides
x^2 = 25
√x^2 = √25
x = 5 or x = -5
Just flip the signs of co-ordinates by using formula y=>-y
- Make sure to do this with y only as it has been reflected to y axis
1) Subtract 6x from both sides. -3y= -9-6x
<span>2) Divide both sides by -3. y= 3+2x </span>
<span>2) Put it in slope-intercept form: y=mx+b. y= 2x+3 </span>
<span>Final answer: y=2x+3</span>
