Answer:

74.4 units

Step-by-step explanation:

Angle T = 48 degrees

now use law of sines

67/sin42  = x/sin48

sin48 * 67/sin 42 = 74.4

Answer:

  C

Step-by-step explanation:

You can reflect point x across the origin to find is is just above -1. Adding 3 to that value gives a point just above -1+3 = 2. That's where point C is located.

__

<em>Algebraic solution</em>

Algebraically, you can set y = -x +3, and solve for x. That gives you ...

  x = 3 -y

Using the relation given at the start:

  0 < x < 1

  0 < 3 -y < 1 . . . . . substitute for x

Adding y gives ...

  y < 3 < y+1

We can separate this into two inequalities:

  y < 3, and

  3 < y+1

  2 < y . . . subtract 1

Now, we have ...

  2 < y < 3 . . . . . the location of point C

As you can see, it is much easier to use the number line directly to find the desired point.

How can u solve this by system of equations by elimination 4x-5y=6;2x+5y=-28
gayaneshka [121]

Answer:

x=17/3, y=10/3. (17/3, 10/3).

Step-by-step explanation:

4x-5y=6

2x+5y=-28

-----------------

4x-5y=6

-2(2x+5y)=-2(-28)

--------------------------

4x-5y=6

-4x-10y=56

------------------

-15y=-50

15y=50

y=50/15

y=10/3

4x-5(10/3)=6

4x-50/3=6

4x=6+50/3

4x=18/3+50/3

4x=68/3

x=(68/3)/4

x=(68/3)(1/4)=68/12=17/3

What is the solution to the system of equations?
kaheart [24]
Substitution would be a great approach to solving this system, because the first equation defines y as x - 10 and you can thus substitute x - 10 for y in the second equation:

2x + (x - 10) = 4

Then 3x - 10 = 4, and 3x = 14.  Solving for x:  x = 14/3.

Since y = x-10, subst. 14/3 for x to find y:  y = 14/3 - 30/3 = -16/3

The solution is (14/3, -16/3).
