5m -2(m + 2) = -(3m +15)
Nostrana [21]

Answer:

m = -11/6

Step-by-step explanation:

5m -2(m + 2) = -(3m +15)

5m - 2m - 4 = -3m - 15

3m + 3m = -15 + 4

6m = -11

m = -11/6

In the interval 0 x 360 find the values of x for which cos x =0.7252
Sergeeva-Olga [200]

Answer:

x_1 = 43.5145\°

x_2 = 316.4855\°

Step-by-step explanation:

We have a positive value for the cosine of x, so we know that the value of x should be in the first quadrant (0 ≤ x ≤ 90) or in the fourth quadrant (270 ≤ x ≤ 360).

Now, let's find the value of x that gives cos(x) = 0.7252 using the inverse function of the cosine, that is, the arc cosine function.

The value of x can be calculated using:

x = arccos(0.7252)

Using this function in a calculator (you may find it as: cos^{-1}(x)), we have that:

x_1 = 43.5145\°

So this is the value of x in the first quadrant. To find the other value of x, in the fourth quadrant, that gives the same result, we just need to calculate 360° minus the value we found:

x_2 = 360\° - 43.5145\° = 316.4855\°

So the values of x are:

x_1 = 43.5145\°

x_2 = 316.4855\°

Solve each system of equations (show steps) y=2x x+y=12
Hunter-Best [27]
Im learning this too right now hope this helps

1.you get y by itself and put what y equals where y is in the other equation
y=2x. x+y=12

x+2x=12
3x=12. (divided 3 on both sides)
x=4

2.after you find x(or y) put it in one of the problems above and solve for whats missing which in this case is y

y=2(4) 4+y=12
y=8. -4. -4
y=8

Use the graph of a translated function below to answer this question
Talja [164]

The graph of the function y=x^3 has the point of inflection at the origin. From the diagram you can the that the graph y=f(x - h) + k has the point of inflection at point (-2,-3). So you should translate the graph of the function y=x^3 2 units to the left and 3 units down. This translation is acting on function  y=f(x) in the following way:

  • translation 2 units to the left - y=f(x+2);
  • translation 3 units down - y=f(x+2)-3.

Then h=-2 and k=-3.

Answer: correct choice is A.
