The first expression, 2(m+10p) represents how much she exercised because Ms. Ghandi runs a mile twice a day and does 10 push ups twice a day so if you take out the common multiple of 2 and multiply it by one set is shows how much she does in a day
the second equation, 2m+20p represents how much she exercises because she runs a mile twice a day and does 10 push ups twice a day
Answer:
(a) (-∞, -8) (-6, -4) (-2, ∞)
(b) -6, -2
(c) negative
(d) 5
Step-by-step explanation:
(a) A function is "decreasing" when the y-value decreases as the x-value increases.
⇒ the function is decreasing over these intervals : (-∞, -8) (-6, -4) (-2, ∞)
(b) Local maxima are the points on the function where it reaches a maximum.
⇒ maxima at x = -6 and x = -2
(c) negative
(d) 5
#10 ) 6/x = 5/11 OR 6/x = 9/19.8
5x = 66 9x = 118.8
x = 13.2 x = 13.2
#11 ) original photo is 5 inches by 7 inches, multiply that , = 35 ( area of original photo )
new photo is "3 times larger" so 5 become 15 and 7 become 21 , multiply that which gives you 315 (area of enlarged photo )
take the enlarged photo's area divided by the original photo's area which gives you 9
#12 ) 6/8 = x/12
72 = 8x
9 = x
#13 ) set equal to find segment TR : 4/10 = 6/x
4x = 60
x = 15
then find the perimeter of triangle by P = a + b + c
P = 10 + 12 + 15
P = 37
