Answer:
(-∞, -4] U [-1, ∞)
Step-by-step explanation:
The quadratic expression factors as ...
x^2 +5x +4 = (x +4)(x +1)
The zeros of this expression are where these factors are zero, at x=-4 and x=-1. The product is negative when one factor is negative and the other is positive, in the region -4 < x < -1. It is non-negative elsewhere. f(x) is defined where the quadratic is not negative, on the union of intervals ...
(-∞, -4] U [-1, ∞)
Can you write out what the problem is please I can barely see it even with clicking on it!
Use this formula:
$5 = $9 then cross multiply 5x= 0.33 x 9
____ _____ You get 5x = 2.97 pounds
<span>0.33 pounds X pounds</span> Then you solve for X.
Divide both sides by 5.
You get 0.594 pounds. Written as a fraction it becomes 59/100 or simply 6/10.
Answer:
70 Bikes
Step-by-step explanation:
[using b as a variable for bikes]
2800=-50b+90b
[2800 is total cost of store with-50 being cost per bike and 90 being selling point of bike]
2800=40b [simplified by combining -50 with 90]
70=b [divided 2800 by 40 to get the break even for the store]
