Answer:

7x^2 + 2x - 4

Step-by-step explanation:

First, combine like terms:  Combine 5x^2 and 2x^2, obtaining 7x^2.  Include the 2x term (there is no like term for this one) and combine -10 +  6, obtaining -4.

Then the sum of these two polynomials is

7x^2 + 2x - 4

Note:  Use " ^ " to indicate exponentiation.

Answer:

7x^2+2x-4

Step-by-step explanation:

a standard form is ax+by=c

5x^2 add 2x^2=7x^2 then -2x but when you have a -10 +6 you get -4 giving you the answer of 7x^2 +2x -4

Can you find the equation in standard form when given 3 or more orders pairs on a parabola
Anettt [7]

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

A line passes through the point (-8,-5) and has a slope of 3/4. Write an equation in point slope form for this line.
timurjin [86]

Answer:

y+5 = 3/4(x+8)

Step-by-step explanation:

The point slope form of the equation of a line is

y - y1 = m(x-x1) where m is the slope and ( x1,y1) is a point on the line

The slope is 3/4 and the point is (-8,-5)

y - -5= 3/4( x - -8)

y+5 = 3/4(x+8)

Hat is the equation of the line through the point (5,-6) slope of-3/5
lutik1710 [3]

Answer:y=-3/5X-9

Step-by-step explanation:

use the formula y=mx+b and plug in your x, y and your slope (m), b is the unknown so you get everything to one side and b by itself so it’s -9 then you plug that all back in
