<h2>Joe Is Right</h2>
Step-by-step explanation:
Twenty-five percent of thirty dollars is <u>$7.50 </u>
(30 x 25)/100 = $7.50
Thirty percent of twenty-five dollars is<u> $7.50 </u>
(25 x 30)/100 = $7.50
Therefore he is right
I hope this helps
Answer:
Company B would be a better choice.
Company B is cheaper.
Step-by-step explanation:
Let x be the rate per square foot
✔️Company A charges: $215 + $0.50x
If they are installing 400 ft² of carpet, they would be charged the following by company A,
Substitute x = 400 into the equation.
We have:
$215 + $0.50(400) = $415
They would pay $415 if they use Company A's services
✔️Company B charges: $100 + $0.75x
If they are installing 400 ft² of carpet, they would be charged the following by company B,
Substitute x = 400 into the equation.
We have:
$100 + $0.75(400) = $400
They would pay $400 if they use Company B's services .
✅Company B would be a better choice because the total charges they would pay to install 400 ft² carpet is cheaper than they would pay for Company A.
Answer:
-1 ≤ y < 6
Step-by-step explanation:
The picture provided has a question of its own. The range of the graph shown is from y=-1 to (almost) y=6. The open circle tells you that the point (-11, 6) is not included in the graph. The range could be written as ...
range: -1 ≤ y < 6
In interval notations, this is ...
[-1, 6)
_____
There is no graph of a quadratic, so we cannot answer any questions related to it.
Gradient is the slope of the line.
Use two points of the graphed line to find the slope, which is the change in Y over the change in x.
I'll use the points (4,0) and (6,8)
Slope = (8-0) / 6/4) = 8/2 = 4
The gradient is 4
Answer:
See graph below
Step-by-step explanation:
The domain is (-∞,∞) and the range is [1,∞)
