The volume of the triangluar block is 4 cubic inches. What is the approximate length of y? -- 2.8 inches
Step-by-step explanation:
12x-15-4x+1=-6
12x-4x= -6+15-1
8x= 8
x=1
my answer is 100 % correct
Answer:
-14
Step-by-step explanation:
Plug 3 in for x
-2 (3)² + 3 + 1
-2 (9) + 3 + 1
-18 + 3 + 1
-14
Let x represent the number of minutes and y the cost. Then
y - 0.85 = (1.10 - 0.85)/(10 - 5) (x - 5)
y - 0.85 = 0.25/5 (x - 5) = 1/20 (x - 5) = 1/20 x - 1/4
y = 0.05x - 0.25 + 0.85 = 0.05x + 0.6
y = 0.05x + 0.6
The cost of 25 minutes = 0.05(25) + 0.6 = 1.25 + 0.6 = $1.85
