Answer:
80%
Step-by-step explanation:
4000 / 5000 * 100 = 80%
8x + y = 12 (substitute 3 for y)
<span>8x + 3 = 12 </span>
<span>8x = 9 </span>
<span>x = 9/8 </span>
<span>If y = 3 and 8x + y = 12, then x = 9/8.
HOPE THIS HELPS!!</span>
By factoring the expression the answer is (3x-2)(x+4). Hope that is helpful.
When you illustrate the problem, an image like that shown in the picture is formed. You are asked to order the angles in increasing order. Since, it did not ask for the values, we don't have to solve it.
Note that the larger the angle, the larger its opening, thus its opposite side would be larger also. Using this analogy and referring to the picture, the order of angles should be:
Angle E < Angle F < Angle D
Answer:
B. (4,12)
Step-by-step explanation:
The process is really easy, all you have to do is substitute the numbers of the ordered pairs into the equations.
So like for A. (-5,8)
Putting this into the equation would look like this,
10 * -5 + 2 * 8 The -5 being substituted for the x and the 8 for the y.
This equation equals to -34, not 64.
3 * -5 - 4 * 8 = -47
not equal to -36, so A is eliminated.
For B. (4,12)
10 * 4 + 2 * 12 = 64
3* 4 - 4 * 12 = -36
These equal to both of the given equations.
For C. (2, 10)
10 * 2 + 2 * 10= 40
3 * 2 - 4 * 10 = -34
These are not equal to the given answers of these equations, C is eliminated.
And D. (-3,11)
10 * -3 + 2 * 11 = -8
3 * -3 - 4 * 11 = -53
These are not equal to the given answers of these equations, D is eliminated.
So the only pair that have made both equations true is B.(4,12)
