All the angles inside a triangle add up to 180°.
(2x + 15) + (5x + 5) + x = 180
8x + 20 = 180
8x = 180 - 20
8x = 160
x = 160/8
x = 20
the question is asking what angle B is,
B = 2(20) + 15
B = 40 + 15
B = 55°
In order to find out the answer for this, let us try to analyze the question. Since it is given that 6240 pounds is the total weight of her 5 horses and t represents the weight of each tack per horse, the inequality that could be used to determine the weight of tack Cari can allow for each horse would be this: <span>6240+5t≤8000
6240+5t indicates the total weight, and that this weight does not exceed 8000. Hope this answer helps.</span>
To find f(5), just look at the table and find the value for x that corresponds with f(5). In this case, this value is -1.
So, your answer is B. -1.
Hope this helps!
Answer:
h(f(x)) = 2x - 11
(the second answer is f(h(x)) = 2x - 4)
Step-by-step explanation:
h(x-7) = 2(x-7) + 3
h(x) = 2x -14 + 3
h(x) = 2x - 11
