Can you find the equation in standard form when given 3 or more orders pairs on a parabola

Mathematics
1 answer:
Anettt [7]3 years ago
8 0

Answer:

Yes, you can

Step-by-step explanation:

The standard form of the equation of a parabola is y=ax^2+bx+c

When given three points, you substitute each point into the equation to obtain 3 simultaneous linear equations.

You then solve the three equations simultaneously to find the values of the constants a,b, and c.

You then substitute these constants into y=ax^2+bx+c

3 in the power of ten word form
Ludmilka [50]

3 in the power of ten means "10^3."

10^3

How to solve exponents is to multiply the number as many times as it's exponent. So in this case you will have to multiply ten, three times.

10\times10\times10=1000

Which would mean that....

10^3=1000

The answer is 10^3.

Hope this helps.

How many solutions does this system of equations have?<br> y = –2x + 3<br> y = –2x – 1
Nadusha1986 [10]

Answer:

Step-by-step explanation:

in y = mx + b form, the slope is in the m position and the y int is in the b position

y = -2x + 3.....slope is -2 and y int is 3

y = -2x - 1...slope is -2 and y int is - 1

same slope, different y int's....means parallel lines...NO SOLUTION

learn this...it helps

same slope, different y int's = no solution

different slopes, different y int's = 1 solution

same slope, same y int's = infinite solutions
