Answer:
to solve a system of linear equations graphically we graph both equations in the same coordinate system, the solution to the system will be in the point where the 2 lines intersect.
Hi there! The answer is A. x = 12
The angles (taken together) are complementary angles: the sum of the angles is 90 degrees. When we know this, we can set up and solve an equation.
(3x + 6) + 48 = 90
Work out the parenthesis
3x + 6 + 48 = 90
Collect terms
3x + 54 = 90
Subtract 54
3x = 36
Divide by 3
x = 36 / 3 = 12
Therefore, the solution for x, gives x = 12. A is the correct answer.
Assuming that we are solving for x when each equation is equal to zero, the solutions are:
1) -.4
2) 1/3
3) 2
4) 7/3
5) -4
Answer:
77.69 + 24.50=102.19
Step-by-step explanation:

<span>There are 8,904 cycles per minute. This would be determining the amount of cycles per second, which is 148.4. After you know the amount per second, you can then multiply it by the time, which in this case is 60 seconds, or 1 minute. 148.4 cycles per second multiplied by 60 seconds is 8,904 cycles.</span>
