Write the polynomial in standard form. Then name the polynomial based on it's degree and number of terms

1 answer:

3 0

First simplify the polynomial by combining terms with the same variable. This is shown below.
5 - 12x + (13x² - 4x²)
5 - 12x + 9x²
Next, arrange the terms in such a way that the exponent of the variable x is decreasing,
9x² - 12x + 5
This is a quadratic trinomial.

Since CB || ED and CB = ED,

by the alternate interior angles theorem,
mE = mC, and mD = mB.

with CB = ED, we can conclude that CBF = EDF, by SAS congruent theorem.

The system shown has the unique solution (2, y, z). Solve the system and select the values that complete the solution. y = 0 y =

madreJ [45]

So we are given a system:
$3x-2y+3z=0\\
-3x - 5y - 5z= -21$
Substitute x = 2 we get the system:
$-2y+3z=-6\\
- 5y - 5z= -15$
Multiply the first equation by -5 and the second by 2 we get the system:
$10y-15z=30\\
- 10y - 10z= -30$
Adding the two equations we get :
$-25z=0\text{ then}z=0.$
We find the value of y by using any of the other equations like this:
$-2y=-6\\y=3.$
Final solution:
$z=0,y=3$

Solve 3x + 7 > -x - 9. Show each step of your work.

Kruka [31]

Answer:

x > -4

Step-by-step explanation:

Inequalities like these are solved the same way equations are solved, except when multiplying both sides you flip the less than/greater than sign:

3x + 7 > -x -9

3x + 7 - 7 > -x -9 -7 Subtract 7 from both sides

3x > -x -16
