Answer:

m = $\frac{-2}{5}$

Step-by-step explanation:

2m + 1 = -3m - 1 (Given)

2m + 1 + 1 = -3m - 1 + 1 (Addition Property of Equality)

2m + 2 = -3m (Simplify)

2m - 2m + 2 = -3m - 2m (Subtraction Property of Equality)

2 = -5m (Simplify)

$\frac{2}{-5} = \frac{-5m}{-5}$ (Division Property of Equality)

$\frac{-2}{5}$ = m (Simplify)

m = $\frac{-2}{5}$ (Symmetric Property of Equality)

Add. (6x3+3x2−2)+(x3−5x2−3) Express the answer in standard form.

sergiy2304 [10]

Answer:

$7x^3-2x^2-5$

Step-by-step explanation:

We need to add the two terms.

$(6x^3+3x^2-2)+(x^3-5x^2-3)$

Solving,

Combine the like terms and adding those terms

$(6x^3+3x^2-2)+(x^3-5x^2-3)\\=6x^3+3x^2-2+x^3-5x^2-3\\=6x^3+x^3+3x^2-5x^2-2-3\\=7x^3-2x^2-5$

So, the answer is:

$7x^3-2x^2-5$

Y-1= 3/2(x+1) write in standard form

Lady bird [3.3K]

Answer:

y = 3/2x (This should be the correct answer do to the fact the slope is 3/2 and the points on here are 1, 1 which would most likely mean the y-intercept is 0. So we don't need to write the y-intercept on this equation.
