-40-2(3m+1/2)=7m-2 what does m equal

kherson [118]

Answer: $m$ = −3

Step-by-step explanation:

Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below.

Step 1: Expand.

−40 − 6 $m$ − 1 = 7 $m$ − 2

Step 2: Simplify −40 − 6 $m$ − 1 to −6 $m$ − 41.

−6 $m$ − 41 = 7 $m$ − 2

Step 3: Add 6 $m$ to both sides.

−41 = 7 $m$ − 2 + 6 $m$

Step 4: Simplify 7 $m$ − 2 + 6 $m$ to 13 $m$ − 2.

−41 = 13 $m$ − 2

Step 5: Add 2 to both sides

−41 + 2 = 13 $m$

Step 6: Simplify −41 + 2 to −39.

−39 = 13 $m$

Step 7: Divide both sides by 13.

− $\frac{39}{13}$ = $m$

Step 8: Simplify $\frac{39}{13}$ to 3.

−3 = m

Step 9: Switch sides.

$m$ = −3

Question 13 y = - X + X^2

ankoles [38]

We have the following function that is a quadratic function:

$y=-x+x^2$

So the graph of this function is shown in the figure below. This is a parabola as you can see. The roots of this functions, that is, the x-intercepts are:

$y=-x+x^2 \\ y=x(x-1) \\ \\ x_{1}=0 \ and \ x_{2}=1$

As you can see in the figure. This function decreases from $(-\infty,0.5)$ and increases from $(0.5, \infty)$

Finally, it is important to note that the vertex is the point:

$V(0.5,-0.25)$

The answer is the second graph.
