Solve for m m/9 + 2/3 = 7/3

Mathematics
1 answer:
V125BC [204]4 years ago
4 0

Answer:

Step-by-step explanation:

Okay so lets put the x values on one side and the whole numbers which are the numbers without variables on the right side.

so now,

m/9 = -2/3 + 7/3

now lets use the inverse operation of division to multiply 9 to separate it from the variable

9(m = -2/3 + 7/3)9

m = -18/3 + 63/3

which can be simplified to,

m = -6 + 21

so,

m = 15.

Hope this helps!

Write a quadratic equation in standard form that has a vertex of (-2, 6) and passes through (-4, -2).
Marizza181 [45]

Answer:

The equation of the quadratic in standard form is:

y=-2x^2-8x-2

Step-by-step explanation:

Since they give us the information about where the vertex of the parabola is located, and one extra points where it passes through, we can use the general form of a quadratic in vertex form:

y-y_v=a\,(x-x_v)^2

where (x_v,y_v) is the location of the vertex (in our case the point (-2,6).

Therefore the equation above becomes:

y-y_v=a\,(x-x_v)^2\\y-6=a\,(x-(-2))^2\\y-6=a\,(x+2)^2

Now,we can use the fact that the point (-4,-2) is also a point of the graph, to find the value of the parameter "a":

y-6=a\,(x+2)^2\\-2-6=a\,(-4+2)^2\\-8=a\,(-2)^2\\-8=a\,*4\\a=-2

Then, the equation of the quadratic with such characteristics becomes:

y-6=-2\,(x+2)^2\\y-6=-2x^2-8x-8\\y=-2x^2-8x-2

which is the equation of the quadratic in standard form.

Find the other endpoint of the line segment with the given endpoint (-2, -2) and midpoint (3,10)
34kurt

9514 1404 393

Answer:

  (8, 22)

Step-by-step explanation:

For endpoints A and B, and midpoint M, the relationship of interest is ...

  B = 2M -A

  B = 2(3, 10) -(-2, -2) = (6+2, 20+2)

  B = (8, 22)

The other end point is (8, 22).
