Answer:
1. B
2. D
Step-by-step explanation:
1. Lon's cost would be the $12 per basket times how many baskets he sells, in this case b plus the cost of the table. Lon's expression is 12b + 75
2. He needs a profit and the only way he could make that profit is if he sells more than 12.
20b > 12b + 75
20 (12) > 12 (12) + 75
240 > 140 + 75
240 > 215
Answer:
(3/8)x^2
Step-by-step explanation:
Rewriting the given expression as follows simplifies the solution. Note that 6x^(-2) could be written as:
6
--------
x^2
Also, (0.5x)^4 = 0.0625x^4.
Then we have:
6*0.0625*x^4 0.375
---------------------- = ------------ * x^(4-2), or (3/8)x^2
x^2 1
Note that x^4 / x^2 = x^2.
Answer:
y= -(1/5)x +1
Step-by-step explanation:
Find slope:
(2+1)/(-5-10) = -1/5
Plug a point and slope into equation (I used -5,2):
y-2=-1/5(x+5)
Change it to slope-intercept form:
y-2=-1/5(x+5)
y-2=-1/5x-1
y=-1/5x+1
Answer:
19
Step-by-step explanation:
f(x) = 2x^2 +1
Let x =3
f(3) = 2 (3)^2 +1
= 2 *9 +1
= 18 +1
= 19
slope line of q= -1/2
perpendicular slopes are those that are opposite sign and reciprocal to the given slope
