Find the sum: (3x2 + 5x − 8) + (5x2 − 13x − 5)

musickatia [10]

Answer:

$(3x^2+5x-8)+(5x^2-13x-5)=8x^2-8x-13$

Step-by-step explanation:

The given polynomials are,

$3x^2+5x-8,5x^2-13x-5$

In polynomial addition and subtraction only like terms can be added or subtracted.

So,

$=(3x^2+5x-8)+(5x^2-13x-5)$

$=3x^2+5x-8+5x^2-13x-5$

$=3x^2+5x^2+5x-13x-8-5$

$=8x^2-8x-13$

Ymorist [56]

Answer:

Not sure if this is right but it might be something like

350,000-4%+1671m

3500,000-4%y/1671m

Step-by-step explanation:

The numbers we know are 350,000 4% and 1671 per month

350,000 is the full mortgage

4% is the APR or annual percentage rate like interest

and we know the monthly for the mortgage is 1671 per month

If ABCDE is reflected over the x-axis and then translated 3 units left, what are the

Aloiza [94]

Answer:

(-6,1)

Step-by-step explanation:

A. Reflection

When you reflect a point (x, y) across the x-axis, the x-coordinate remains the same, but the y-coordinate gets the opposite sign.

Thus, D (-3,-1) ⟶ D' (-3, 1)

B. Translation

When you translate a point horizontally, its x-coordinate changes, but the y-coordinate. remains unchanged.

You translated the point 3 units to the left.

D'(-3, 1) ⟶ D"(-6,1)
