How do i identify the slope,y intercept,x intercept, and zero on a graph
Answers
To find the slope of a line, you need to find the change in x over the change in y, or rise over run. You can do this by taking two points and using the formula .
To find the y-intercept, find where the graph touches the y-axis.
To find the x-intercept, find where the graph touches the x-axis.
Zeroes on a graph are the same as its x-intercepts.

Answer:
$48.97
Step-by-step explanation:
Let p represent the marked price of the mower. Then the price with tax is ...
with tax = p + 7.3%×p = 1.073p
The amount Flicka paid is the amount tendered less the change she received, so is ...
3×$20 - 7.45 = with tax = 1.073p
To find p, we can divide by its coefficient:
(3 × $20 - 7.45)/1.073 = p ≈ $48.97
The selling price before taxes was $48.97.

Comment on the problem
If you check the answer, you find the amount with tax is ...
$48.97 × 1.073 ≈ $52.54481 ≈ $52.54
so the change Flicka would have received would have been $7.46, not $7.45. If the price were $48.98, then the change would have been $7.44. There is no price at which the mower can be marked that will make the total with tax come to $52.55. There is no solution to this problem.
Answer:
$48.97
Step-by-step explanation:
She paid three $20 bills
3 × 20 = $60
She received $7.45 change
60 - 7.45 = $52.55
The mower was for $52.55 with sales tax.
The sales tax is 7.3%.
Before the sales tax (reduce tax).
52.55 × (1-7.3%)
= $48.97

Answer:
the sample standard deviation
Step-by-step explanation:
The statistic that would enable Dan to estimate the probability that any single class will last somewhere between 47 and 53 minutes is the sample standard deviation. If we have the mean and the standard deviation and we know that the lenghts of the classes form a normal curve, we can compute probabilities either with the empirical rule or using a table of probabilities from a book. The normal distribution is completely determined with the mean and the standard deviation.

If the two spheres are tangent, then the intersection is by definition a point.
Since the two spheres are of unequal diameter, their intersection can't be a sphere (that can only happen if the spheres are of the same diameter and at the same point, then they overlap everywhere).
Now what happens if the two spheres are drawn close to each other a random way ? Well, they will intersect along a circle [see the image attached].
If you want more explanations/..., feel free to ask.

Which of these shows how to plot the point to mark the skating rink?
From the origin, move 1.5 units to the left along the x-axis and 1 unit vertically down, and place the point.
From the origin, move 1 unit to the left along the x-axis and 1.5 units vertically down, and place the point.
From the origin, move 1 unit to the right along the x-axis and 1.5 units vertically down, and place the point.
From the origin, move 1.5 units to the right along the x-axis and 1 unit vertically down, and place the point.
Answers
Answer:
The correct option is 1.
Step-by-step explanation:
It is given that the skating rink is at (−1.5, −1).
Here, x-coordinate is -1.5 and y-coordinate is -1.
In a point P(a,b),
If a>0, then the point P is a units right from the origin and if a<0, then the point P is a units left from the origin.
If b>0, then the point P is b units up from the origin and if b<0, then the point P is b units down from the origin.
It the given point (-1.5, -1), a=-1.5 and b=-1 both are negative.
From the origin, move 1.5 units to the left along the x-axis and 1 unit vertically down, and place the point.
Therefore the correct option is 1.
Moving 1.5 units to the left (or -1.5 units to the right).
Moving 1 unit down (or -1 unit up).
Therefore you get the result of (-1.5, 1) as is the location of the rink.
