Check attached graph of the line in picture

Step-by-step explanation:

Step-by-step explanation:

We have been given an equation y+6=45(x+3) in point slope form.

It says to use the point and slope from given equation to create the graph.

So compare equation y+6=45(x+3) with point slope formula

y-y1=m(x-x1)

we see that m=45, x1=-3 and y1=-6

Hence first point is at (-3,-6)

slope m=45 is positive so to find another point, previous point will move 45 units up then 1 unit right and reach at the location (-2,39).

Now we just graph both points (-3,-6) and  (-2,39) and join them by a straight line. Final graph will look like the line in attached graph.

Answer:

512 baseball cards

Step-by-step explanation:

At 13, Stephanie had 137 baseball cards.

There are 28-13 = 15 years between 13 and 28

For those 15 years, she got 25 cards a year.

15 * 25 = 375

In those 15 years, she got 375 cards.

She started with 137, and she gained 375.

137+375 = 512

She now has   512 cards.

Answer:

The ratio given is part to part. The total number of parts in the whole is 1 + 3 = 4.

Step-by-step explanation:

We know that partitioning a directed line segment into a ratio of 1:3 means that we are dividing the given line segment into two parts whose first part is 1 times the of some quantity while the another part is 3 times of the same quantity. So basically we are comparing part to part in by ratio. And total number of parts in the whole will be just sum of both so we get 1+3=4

Hence choice (3) is correct answer.

"The ratio given is part to part. The total number of parts in the whole is 1 + 3 = 4."

Final answer:

Partitioning a directed line segment into a ratio of 1:3 is not the same as finding the length of the directed line segment. The ratio compares parts within the whole, while finding the length involves measuring the entire segment. To find the length of each part in a 1:3 ratio, divide the length of the segment by 4.

Explanation:

Partitioning a directed line segment into a ratio of 1:3 is not the same as finding the length of the directed line segment because the ratio given is part to whole, while finding the length involves determining the actual measurement of the segment. The ratio 1:3 compares the parts within the whole, while finding the length of the segment involves measuring the entire length.

When the ratio is given as 1:3, it means that the segment is divided into 4 equal parts (1 part + 3 parts). The length of the entire segment is the sum of these 4 parts. To find the length of each part, you can divide the length of the segment by 4.

For example, if the length of the segment is 8 units, each part will have a length of 8/4 = 2 units.

The slope-point form of line:

[tex]y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have the points (-9, 7) and (6, 2). Substitute:

[tex]m=\dfrac{2-7}{6-(-9)}=\dfrac{-5}{6+9}=-\dfrac{5}{15}=-\dfrac{1}{3}\\\\y-7=-\dfrac{1}{3}(x-(-9))\\\\\boxed{y-7=-\dfrac{1}{3}(x+9)}[/tex]

The slope-intercept form of line:

[tex]y=mx+b[/tex].

We have the slope m:

[tex]y=-\dfrac{1}{3}x+b[/tex]

Pu the coordinates of the point (6, 2) to the equation:

[tex]2=-\dfrac{1}{3}(6)+b[/tex]

[tex]2=-2+b[/tex]             add 2 to both sides

Answers:

Problem 1) ASA

Problem 2) ASA

Problem 3) AAS

Problem 4) Neither

Problem 5) AAS

Problem 6) Neither

==============================

Explanation:

Any time we have ASA is when we can match up two pairs of angles and a pair of sides between the two pairs of angles. With problems 1 and 2, this happens. The corresponding angles that are congruent are the ones that have the same angle markers.

AAS is slightly different from ASA in that the side is not between the angles. This happens with problem 3 and problem 5. For problem 3, for instance, the second pair of angles are the two vertical angles. These angles are not marked, but they are congruent due to the vertical angle theorem. The same thing can be said about problem 5 as well.

With problem 4 and problem 6, we don't have any information about any pairs of angles, so we can't use AAS or ASA at all. We don't know if the triangles are congruent or not. They might be, but we simply don't have enough info to say either way.

Answer:

The congruent side length is 6. The third side length is 3.

Answer:

30 students

Step-by-step explanation:

Yesterday: 1/3 of the 75 students (75 / 3) = 25 students

There are now 50 students remaining to give their speeches.

Today: 2/5 of the 50 students (50 / 5 = 10 x 2 ) = 20 students

50 - 20 = 30 students remaining to give their speeches.

Therefore, 30 students still haven't given their speeches.

To find out how many students still haven't given their speeches, we first need to calculate the number of students who gave their speeches yesterday and today. Since there were 75 students in total and 1/3 of them gave their speeches yesterday, we multiply 75 by 1/3:

75 * 1/3 = 25 students

This means that 25 students gave their speeches yesterday. To find out how many students were left for today, we subtract the number of students who gave speeches yesterday from the total number:

75 - 25 = 50 students remained

Today, 2/5 of the remaining students gave their speeches. We calculate this by multiplying the number of remaining students by 2/5:

50 * 2/5 = 20 students

Therefore, 20 students gave their speeches today. Now, we subtract the number of students who have given their speeches today from the remaining number of students to find out how many have not given their speeches yet:

50 - 20 = 30 students

Thus, 30 students still haven't given their speeches.

$1062.5

Step-by-step explanation:

Since it is given that Money is increased by 25% from July to December.

Also, Mike deposit $850 in a bank account

Thus, He get money at the end of December = $850 × (100 + 25)%

In the number 526, the underlined digit '5' represents the 100's place, so its value is not simply 5, but 500. A helpful tool to work with such problems is the place value chart.

In the number 526, the emphasized or underlined digit represents the 100's place. So, the value of this specific digit, which happens to be 5, isn't simply 5 but 500 in the context of this particular group of digits. You can easily understand this by breaking down the number: 526 equals 500 (5 hundreds) plus 20 (2 tens) plus 6 (6 ones).

Another easy method to identify the value of an underlined or specific digit in a number is by knowing the place value chart, which runs from right to left as: Ones, Tens, Hundreds, Thousands, and so on. The third digit from right is the Hundreds place, and since in 526, 5 is in this position, its value becomes 500.

[tex]\frac{17}{2}= l\times \frac{17}{5}[/tex]

Multiply both sides by [tex]\frac{5}{17}[/tex] we get;

[tex]l = \frac{17}{2} \times \frac{5}{17} =\frac{5}{2} = 2\frac{1}{2}[/tex] feet.

Therefore, the length in feet is, [tex]2\frac{1}{2}[/tex]

Final answer:

The y-intercept of function f(x) can be found by using the given points to determine the slope and then plugging in the slope and a point into the point-slope equation. The y-intercept of function g(x) is given by the table. The positive difference in the y-intercept values of f(x) and g(x) is -0.5.

Explanation:

The y-intercept of a linear function represents the value of the function when x is equal to 0. To find the y-intercept of function f(x), we can use the given points (0,1) and (2,7) to determine the slope of the line. The slope is calculated by taking the difference in the y-coordinates and dividing it by the difference in the x-coordinates:

slope = (7 - 1) / (2 - 0) = 3.

Now that we have the slope, we can use the point-slope form of a linear equation to find the equation of the line:

y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.

Using the point (0,1) and the slope 3, we get:

y - 1 = 3(x - 0).

Simplifying the equation gives us:

y = 3x + 1.

The y-intercept of function g(x) is given by the table as the value of g(x) when x = -1, which is 1.5.

The positive difference in the y-intercept values of f(x) and g(x) is given by:

1 - 1.5 = -0.5.

13. The points that shows f(x) = g(x) are (0, 3) and (4, -5)

14a, h(45) = 7 means that after 45 days of planting the height will be 7 cm

14b. h(65) = 11

15a. g(t) = 1

15b. f(x) = 11

16. t = 8

How to find the solution of the graph

13. The solution of the graph is the point of intersection of the line and the curve

14. For the function, the value after the equality sign shows the value h while the value in the parenthesis shows the value for t

15. g(t) = 4t - 7

g(2) = 4(2) - 7 = 1

f(-3) = (-3)² + 2 = 11

f(t) = 14 - 3t

-10 = 14 - 3t

-24 = -3t

-24/-3 = t

t =8
