Answer:
The x-intercept of the function is 4 which represents the total time of the trip, in hours.
Step-by-step explanation:
Since Skylar was a distance of 0 miles from City A after 4 hours, the x-intercept of 4 represents how many hours it took Skylar to drive from her house to City A.
Have a good day :)
The x- intercept is 4 hours.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δxwhere,m is the slope
Given:
D=120-30t.
According to slope - intercept form
y= mx+ b
where m is the slope and b is the y intercept.
So, the x-intercept
0= 120- 30t
t= -120/ (-30)
t= 4
Hence, the x- intercept is 4 hours.

Three children's tickets to the circus cost
$53.85. Two adult tickets to the circus
cost $63.90. How much more does
1 adult ticket cost than 1 children's ticket?
Answer:
$14
Step-by-step explanation:
53.85 divided by 3 is 17.95
63.90 divided by 2 is 31.95
31.95-17.95=14
Answer: $14
Step-by-step explanation:
First find out how much each child's ticket costs. 53.85/3 = 17.95. Then find of the same thing for an single adult ticket. 63.90/2 = 31.95. Finally we subtract both numbers 31.95-17.95= 14 dollars. Thats your answer

Which answer is an equation in point-slope form for the given point and slope?
Point: (5, 9); Slope: 2
y-5= 2 (2 +9)
y-9=2(x+5)
y+9= 2(2-5)
y-9=2(x – 5)
Answer: y-9=2(x-5)
Step-by-step explanation: The point (5,9) satisfies the equation:
y-9=2(x-5) for (5,9)?
9-9=2(5-5) ?
0 = 0 YES
Slope of 2? Rewrite:
y-9=2(x-5)

Estimate the following square and cube roots by using the above process. Circle
any Rational Roots.
Please help❗️❗️❗️❗️❗️
The estimates of the square roots and cube roots using the attached process are;
1) √15 = 3.81
2) √44 = 6.6.
3) √81 = 9
4) ∛12 = 2.88.
5) ∛125 = 5
6) ∛320 = 6..8
The process we are to follow is shown in the attachment. The first thing we are to do is to list all the perfect squares from 1 to 100 and then do the same for all perfect cubes from 1 to 1000.Perfect squares from 1 to 100; 4, 9, 16, 25, 36, 49, 64, 81, 100
Perfect cubes from 1 to 1000; 1, 8, 27, 64, 125, 216, 343, 512, 729 and 1000.
1) √15;
The nearest perfect squares to it are; 9 and 16
Thus; √9 < √15 < √16
⇒ 3 < √15 < 4
This means that √15 is between 3 and 4.
Since 15 is closer to 16 than 9, it means √15 is closer to 4 and thus, we can estimate √15 as 3.81.
2) √44;
The nearest perfect squares to it are; 36 and 49
Thus; √36 < √44 < √49
⇒ 6 < √44 < 7
This means that √44 is between 6 and 7.
Since 44 is closer to 16 than 9, it means √44 is closer to 6 and thus, we can estimate √44 as 6.6.
3) √81
This is a perfect square and the method used to estimate other non-perfect square doesn't apply here. Thus; √81 = 9
4) ∛12
The nearest perfect cubes to it are; 8 and 27
Thus; ∛8 < ∛12 < ∛27
⇒ 2 < ∛12 < 3
This means that √12 is between 2 and 3.
Since 12 is closer to 8 than 27, it means ∛12 is closer to 2 than 3 and thus, we can estimate ∛12 as 2.88.
5) ∛125
This is a perfect cube and the method used to estimate other non-perfect cubes doesn't apply here. Thus; ∛125 = 5
6) ∛320
The nearest perfect cubes to it are; 216 and 343
Thus; ∛216 < ∛320 < ∛343
⇒ 6 < ∛320 < 7
This means that ∛320 is between 6 and 7.
Since 320 is closer to 343 than 216, it means ∛320 is closer to 7 than 6 and thus, we can estimate ∛320 as 6..8

Write this polynomial in descending order. Enter exponents using the caret
(). For example, enter x2 as x^2.
-7 + 8x2 - 4x
Answer: 8x^2 -4x -7
Step-by-step explanation: the x^2 term comes first, followed by the x, then the constant which in this case is -7
so it would be 8x^2 -4x -7
The polynomial -7 + 8x² - 4x written in descending order is 8x² - 4x - 7.
To write the polynomial -7 + 8x² - 4x in descending order, we arrange the terms from highest degree to lowest degree.
Here's how to do it step by step:
Step 1: Identify the degree of each term:
The term -7 has a degree of 0 (since it is a constant).
The term 8x² has a degree of 2 (since it has a variable raised to the power of 2).
The term -4x has a degree of 1 (since it has a variable raised to the power of 1).
Step 2: Arrange the terms in descending order based on their degrees:
Start with the term with the highest degree and proceed in decreasing order. In this case, we have only three terms, so we start with the highest degree term:
8x² (degree 2)
Next, we consider the next highest degree term:
-4x (degree 1)
Finally, we have the constant term:
-7 (degree 0)
Step 3: Write the polynomial in descending order:
Putting the terms together in descending order, we have:
8x² - 4x - 7
So, the polynomial -7 + 8x² - 4x written in descending order is 8x² - 4x - 7.
