3x +15 = 2x + 10 + x + 5

Shkiper50 [21]

Answer:

The equation is true.

Step-by-step explanation:

Simplify. Combine like terms:

3x + 15 = (2x + x) + (10 + 5)

3x + 15 = (3x) + 15

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 3x and 15 from both sides:

3x (-3x) + 15 (-15) = 3x (-3x) + 15 (-15)

3x - 3x = 15 - 15

0 = 0

~ True. The two expressions are equal to each other.

Find the slope of the given line on the graph. REMEMBER: Rise over run! <br> Pls show work!

Leviafan [203]

Answer:

the slope is $-\frac{1}{3}$

Step-by-step explanation:

Notice that you are given two points to use for the slope calculation:

$(x_1,y_1)=(-4,4) \,\,and\,\, (x_2,y_2)=(5,1)$

So we use the formula for the slope of a line given two points:

$slope\,=\,\frac{y_2-y_1}{x_2-x_1} \\slope\,=\,\frac{1-4}{5-(-4)} \\slope\,=\,\frac{-3}{9} \\slope\,=\,-\frac{1}{3} \\$
