Final answer:
The slope of the line that passes through the points (-6, -7) and (-24, -7) is calculated using the slope formula and is found to be 0, indicating that the line is horizontal.
Explanation:
The question asks for the slope of the line that passes through the points (-6, -7) and (-24, -7). To calculate the slope, we use the formula slope = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points. Plugging in our values, we get the slope = (-7 - (-7)) / (-24 - (-6)) = 0 / -18 = 0. Therefore, the slope of the line through these two points is 0, which means the line is horizontal.

1. y = 4x + 3 for x = -1, 0,1
Answer:
-1, 3, 7
Step-by-step explanation:
y = 4(-1) + 3
y = -4 + 3
y = -1
y = 4(0) + 3
y = 0 + 3
y = 3
y = 4(1) + 3
y = 4 + 3
y = 7
To solve the linear equation y = 4x + 3, substitute the given x values (-1, 0, 1) into the equation to find the corresponding y values. The results are -1, 3, and 7 respectively.
Explanation:The question asks to solve the equation y = 4x + 3, for the values of x being -1, 0, and 1. This is a linear equation where y depends on x. To find the corresponding y values for each x value:
Substitute x = -1 into the equation. The calculation becomes: y = 4(-1) + 3 = -4 + 3 = -1.Substitute x = 0 into the equation. The calculation becomes: y = 4(0) + 3 = 0 + 3 = 3.Substitute x = 1 into the equation. The calculation becomes: y = 4(1) + 3 = 4 + 3 = 7.Hence, the values for y when x equals -1, 0, and 1 respectively are -1, 3, and 7.

Answer:
Explain wether the graph represents a function.The graph represents a function because each x-value corresponds to exactly one y-value.
For example, in the given graph you see that for x=2 there's only one corresponding value, which is, y=40, that's what defines a function. If you have a graph where a certain value of x has to y values, that means is not a function, because for one x-value would be more than one y-values, so that would be only a relation, not a function.
It's important to specify the right order, that is, if we say each y-value corresponds to exactly one x-value, that's not exactly de definition of a function, because it actually happens, because in a quadratic expression, 2 and -2 would be the same result 4, so one y-vale has two x-value, but it's still a function.
So, the right order is The graph represents a function because each x-value corresponds to exactly one y-value.

Priya is riding at a constant speed of 12 miles per hour. Write an expression that shows how many miles Priya has gone after Han has been riding for hours.
Use your expressions to find when Han and Priya meet.
I copy the complete questions again to make them clearer:
Priya and Han are biking in the same direction on the same path.
a. Han is riding at a constant speed of 16 miles per hour. Write an expression that shows how many miles Han has gone after [tex]t[/tex] hours.
b. Priya started riding a half hour before Han. If Han has been riding for [tex]t[/tex] hours, how long has Priya been riding?
c. Priya is riding at a constant speed of 12 miles per hour. Write an expression that shows how many miles Priya has gone after Han has been riding for [tex]t[/tex] hours.
d. Use your expressions to find when Han and Priya meet.
Answer:
a) [tex]H=16t[/tex]b) [tex]t+0.5[/tex]c) [tex]P=12(t+0.5)[/tex]d) Han and Priya meet 1.5 hours after Han started riding.Explanation:
a. Since Han is riding at a constant speed of 16 miles per hour, the number of miles that he has gone is proportional to the number of hours, t, that he has been riding, the constant of variation is 16, and the expression for the number of miles he has gone is:
[tex]H=16\times t=16t[/tex]Where, H is the number of miles Han has gone, and t is the number of hours.
b. Since Priya started riding a half hour before Han, you have to add 1/2 or 0.5 to the time of Han, which is t, to express how long Priya has been riding:
[tex]t+0.5[/tex]c. Since, Priya is riding at a constant speed of 12 miles per hour, the number of miles that she has gone is proportional to the number of hours, t + 0.5, that she has been riding, the constant of variation is 12, and the expression for the number of miles she has gone is:
[tex]P=12\times (t+0.5)=12(t+0.5)[/tex]Where P is the number of miles Priya has gone, and t is the number of hours since Han is riding.
d. To find when Han and Priya meet, you just need to solve the sytem of equations, making H = P, which means that the number of miles that both Han and Priya rides is equal:
[tex]H=P\\ \\ 16t=12(t+0.5)\\ \\ 16t=12t+6\\ \\ 4t=6\\ \\ t=6/4=3/2=1.5[/tex]
Which means that they meet when it has passed 1.5 hours since Han started riding.

In Mr. Ben's class, 1/4 of the kids have others siblings in the school.
1. What fraction of the students in the school are in grade 4?
2. What fraction of the grade 4 students are boys?
3. What fraction of the grade 4 students are in Ms. Ashley's class?
4. What fraction of the students in Mr. Ben's class that do not have siblings in the same school?
5. In Ms. Ashley's class, are there more students that wear glasses or do not wear glasses?
Answer:
1. 45/482 of the students are in grade 4.
2. 5/9 of the students of the grade 4 are boys.
3. 7/15 of the grade 4 students are in Ms. Ashley's class
4. 3/4 of the students in Mr. Ben's class do not have siblings in the same school.
5. There are 14 students with glasses and 7 without glasses.
Step-by-step explanation:
1. Let's review the information given to us for solving the questions:
Number of students in the school = 482
Ms. Ashley's Grade 4 class = 21 students
Ms. Ashley's Grade 4 class boys = 15 students
Ms. Ashley's Grade 4 class girls = 6 students
Ms. Ashley's Grade 4 class with glasses = 2/3 * 21 = 42/3 = 14 students
Mr. Ben's Grade 4 class = 24 students
Mr. Ben's Grade 4 class boys = 10 students
Mr. Ben's Grade 4 class girls = 14 students
Mr. Ben's Grade 4 class with siblings in the school = 1/4 * 24 = 24/4 = 6 students
2. Let's answer all the questions:
1. What fraction of the students in the school are in grade 4?
(Ms. Ashley's Grade 4 class + Mr. Ben's Grade 4 class)/ Number of students in the school
21 + 24 / 482 = 45/482
2. What fraction of the grade 4 students are boys?
(Ms. Ashley's Grade 4 boys + Mr. Ben's Grade 4 boys)/ (Ms. Ashley's Grade 4 class + Mr. Ben's Grade 4 class)
15 + 10 / 21 + 24
25 / 45 = 5/9
3. What fraction of the grade 4 students are in Ms. Ashley's class?
Ms. Ashley's Grade 4 class / (Ms. Ashley's Grade 4 class + Mr. Ben's Grade 4 class)
21 / 21 + 24
21 / 45 = 7/15
4. What fraction of the students in Mr. Ben's class that do not have siblings in the same school?
(Mr. Ben's Grade 4 class - Mr. Ben's Grade 4 class with siblings in the school)/ Mr. Ben's Grade 4 class
24 - 6 / 24
18 / 24 = 3/4
5. In Ms. Ashley's class, are there more students that wear glasses or do not wear glasses?
There are 14 students with glasses and 7 without glasses.

Marcela estimates the distance between the library and town hall is 735 ft. The actual distance is 612 ft.
What is the percent error in Marcela's estimate?
Round your answer to the nearest tenth of a percent.
Enter your answer in the box.
Answer:
The error percentage in estimation is 20 %

For which discriminant is the graph possible
b2-4ac=0
b2-4ac=-1
b2-4ac=4
Answer:
"[tex]b^2-4ac=4[/tex]"
Step-by-step explanation:
By looking at the value of the discriminant in a quadratic, we can find the nature of roots.
Let the value of the discriminant be "D", so we can say:
D > 0 [2 distinct real roots]D = 0 [2 same real roots]D < 0 [no real roots]Graphically, we can write the points in order as:
D > 0, 2 cutting point in x-axisD = 0, 1 touching point in x-axisD < 0, NO cutting/touching point in x-axisLooking at the graph, we clearly see that there is 2 cutting points in the x-axis, so there are 2 roots. This means the value of the discriminant should be greater than 0 (positive value).
Out of the 3 choices given with discriminant formula, the last one has a value that is greater than 0:
4 > 0
Hence, last answer choice is right.
The discriminant determines whether a quadratic equation has real solutions and affects the appearance of the graph.
Explanation:The discriminant is calculated using the formula Δ = b² - 4ac. In order for the graph to be possible:
If Δ = 0, the quadratic equation will have one real root. The graph will touch the x-axis at one point.If Δ < 0, the quadratic equation will have no real roots. The graph will not intersect the x-axis and will be entirely above or below it.If Δ > 0, the quadratic equation will have two distinct real roots. The graph will intersect the x-axis at two points.Therefore, for the discriminant values given:
For Δ = 0, the graph is possible.For Δ = -1, the graph is not possible.For Δ = 4, the graph is possible.Write the decimal as a fraction or a mixed number in simplest form.
