<span>Tammy should use the machine to maintain or decrease her intensity. 183 is a very high heart rate and indicates that she is working at, or near, a maximal effort. She should not increase the intensity (speed or incline).</span>
Answer:
To find the horizontal asymptote, we note that the degree of the numerator is one and the degree of the denominator is two. Since the larger degree occurs in the denominator, the graph will have a horizontal asymptote at y = 0 (i.e., the x-axis). The vertical asymptotes will occur at those values of x for which the denominator is equal to zero.

The answer to your question is:
x = 21
y = 4
∡ = 75° and 105°
Step-by-step explanation:
Process
3(x + y)° + 5x = 180 supplementary angles
3(x + y) = 4x - 9 corresponding angles
Expanding
3x + 3y + 5x = 180 (1) Like terms
3x + 3y = 4x - 9 (2)
8x + 3 y = 180 (1)
8 ( -x + 3 y = -9) (2) Multiply by 8
8x + 3y = 180 (1)
-8x +24y = -72 (2) Elimitation method
27 y = 108
y = 108 / 27
y = 4
8x + 3 (4) = 180
8x +12 = 180
8x = 168
x = 21
3(21 + 4) = 3(25) = 75°
5(21) = 105°
a perfect square trinomial has a factor that is identical to the other factor. In this case, from the first term, the factor is composed of 2x while from the third term, there is a term 7 involved. In this case, the factor is 2x + 7. so the second term has to be 2*(2*7) equal to 28
