Answer:-5 to2
Step-by-step explanation:
the point on the very left is at (-5, -5), and since the domain is also the x-value, the domain becomes -5. The point at the most right is at (2, -2), the domain being 2. So, the domain of the function is -5 to 2.
Answer: 6.4 hours
Step-by-step explanation:
Hi, to answer this question we have to write an equation for each case:
Happy paws: the cost is equal to the fixed charge (19) plus the product of the charge per hour (3.50) and the number of hours (h).
Happy Paws Cost = 19+3.50h
Woof Watchers: the cost is equal to the fixed charge (11) plus the product of the charge per hour (4.75) and the number of hours (h).
Woof Watcher Cost = 11+ 4.75h
Since both costs must be equal:
Happy Paws Cost =Woof Watcher Cost
So:
19+3.50h = 11+ 4.75h
Solving for h:
19-11 = 4.75h-3.50h
8 = 1.25h
8/1.25 =h
h = 6.4 hours
Answer:
<em>No</em>
Step-by-step explanation:
y - x = 4 can be rewritten as
y = x + 4
This is the equation of a line, so this equation is linear.
For an equation to be direct variation, it must have the form
y = kx, where k is a number called the constant of proportionality.
If you rewrite y = x + 4 as y = 1x + 4, you still have the 4 there that cannot be in a direct variation equation.
Answer: No,
Answer:
Step-by-step explanation:
The diameter is 0.45 in
The percent error is < 4%
<u>The lower limit of allowance is:</u>
- 0.45 - 4% =
- 0.45*(1 - 0.04) =
- 0.45*0.96 =
- 0.432
Less than 4% error means the diameter should be greater than 0.432 in.
The bolt with the diameter 0.43 in is outside of the allowance and should <u>not</u> go into the package
Vertical line has no slope. so only look at the x value. x=-4.
