The slope (m) that passes through the given points (4, 3) and (6, 7) is (B) 2.
What is the slope?The value of the steepness or the direction of a line in a coordinate plane is referred to as the slope of a line, also known as the gradient. Given the equation of a line or the coordinates of points situated on a straight line, a slope can be determined using a variety of approaches. A line's steepness can be determined by looking at its slope. The slope is calculated mathematically as "rise over run" (change in y divided by change in x).So, the slope will be:
Points are: (4, 3) and (6, 7)Slope formula: m = y2 - y1/x2 - x1Now, calculate as follows:
m = y2 - y1/x2 - x1m = 7 - 3/6 - 4m = 4/2m = 2Therefore, the slope (m) that passes through the given points (4, 3) and (6, 7) is (B) 2.

The position of museum relative to hotel will be (9,1) as the starting position will be (0,0) that is her hotel then the position of coffee shop is (-2,4) and at the end position of museum is (7,5).
What is coordinate?A set of values indicating an exact position. On graphs, it is typically represented by a pair of numbers: the first number represents the distance along, and the second number represents the distance up or down. The location in the cartesian plane will be defined by the coordinate points. The distance between two points is known as the x-coordinate, or abscissa, and the distance between two points is known as the y-coordinate. To find the coordinates of a point in a coordinate system, do the inverse. Start at the point and trace a vertical line up or down to the x-axis. There you have your x-coordinate. Then repeat the process, but this time follow a horizontal line to find the y-coordinate.
Here,
The starting coordinate=0,0
The second coordinate=-2,4
The ending coordinate=7,5
The required coordinate will be
=7--2-0,5-4-0
=9,1
The position of the museum in relation to the hotel is (9,1) because the starting point is (0,0) that is her hotel and the position of the coffee shop is (-2,4) and the position of museum is (7,5).

What’s is the probability of spinning a 4 on the spinner below
The probability of spinning a 4 on the spinner is 1/12.
Given, a spinner having two numbers 4 & 9
the sector having number 9 has an angle of 30°.
We have to find the probability of spinning a 4 on the spinner
So, the probability of spinning a 4 is,
Probability = (Area of sector having number 4)/(Area of the circle)
Probability = (30°/360°×π×r²)/(π×r²)
Probability = 1/12
Hence, the probability of spinning a 4 on the spinner is 1/12.

A sector has radius 12 and central angle 64°. Find the area of the sector.
We need to find the area of the sector which is given by the next formula:
Area of the sector = ( central angle / total angle ) * area of the circle
First, we need to find the area of the circle:
[tex]\begin{gathered} A_c=\pi\ast r^2 \\ Replacing \\ A_c=\left(12\right)^2\pi \\ A_c=144\pi \end{gathered}[/tex]Now, we can use the formula for the area of the sector
Central angle = 64
The total angle of a circle= 360
Area of the circle = 144π
Replacing using the formula:
Area of the sector = (64/360) * 144π
Area of the sector = 128π/5
Area of the sector = 80.42477

Step-by-step explanation:
The student council sold two types of ice cream, sundaes and cones, during homecoming week. Each sundaes cost the same amount, and each cones cost the same amount.
One the first day they earned $210 for selling 125 cones and 10 sundaes
One the second day they earned $256 for selling 100 cones and 30 sundaes.
What was the cost in dollars for each cone sold by the student council?
Answer:
1 cone = $1.36
Step-by-step explanation:
125 c + 10 s = $210
100 c + 30 s = $256
make one of the terms the same (easier one = 30 sundaes)
125 × 3 = 375 c
10 × 3 = 30 s
210 × 3 = $630
375 c + 30 s = $630
375 c + 30 s = $630
100 c + 30 s = $256
same sign = subtract
375 - 100 = 275 c
30 - 30 = 0 s
630 - 256 = $374
275 c = $374
÷ 275 on both sides to get c
c = $1.36

Step-by-step explanation:
The amount invested at an 8% rate would be $184 because 2,300 x 0.08 (8% in a decimal form) x 1 (since it was after 1 year) would come to 184.
The amount invested at an 3% rate would be $69 because 2,300 x 0.03 (3% in a decimal form) x 1 (since it was after 1 year) would come to 69.

In this case, we'll have to carry out several steps to find the solution.
Step 01:
perimeter = ?
x + 4 = width
2x - 3 = length
Step 02:
perimeter = 2* width + 2*lenght
perimeter = 2 * (x + 4) + 2 * (2x -3)
= 2x + 8 + 4x - 6
= 6x + 2

O B.y=x+3
O C. y=x-3
O D.y=3-x
Using the equation of slope intercept form, the equation of the given graph is y=x-3.
In the given question we have to find equation of the given graph.
From the given graph the points are (3,0) and (0,-3).
We know the standrd equation of the line is y=mx+c
where m=slope and c=value of y at the y intercept form.
So the value of c= -3
Now finding the value of m.
m={y(2)-y(1)}/{x(2)-x(1)}
From the points, x(1)=3, x(2)=0, y(1)=0, y(2)= -3
Putting the value
m=(-3-0)/(0-3)
m=-3/-3
m=1
Now putting the value of m and c in the equation
y=mx+c
y=1*x+(-3)
y=x-3
Hence, the equation of the given graph is y=x-3.

We have the following function:
[tex]G(x)=x^4[/tex]In a function, to move it to the right or to the left we must add if we want to move to the left and we must subtract if we want to move to the right.
But we must add or subtract within the exponent, since it moved 2 to the right we must subtract 2 units, just like this:

From the question;
we are to determine if the point (-2, 11) is on the circle with radius 5 and center (2, 13)
The equation of a circle with a radius r and center (a, b) is given as
[tex](x-a)^2+(y-b)^2=r^2[/tex]Hence, the equation of the circle with radius 5 and center (2, 13)
[tex]\begin{gathered} (x-2)^2+(y-13)^2=5^2 \\ (x-2)^2+(y-13)^2\text{ = 25} \end{gathered}[/tex]Considering the point (-2, 11), we need to substitute the values for x and y
therefore, x = -2, y = 11
[tex]\begin{gathered} (-2-2)^2+(11-13)^2\text{ }\ne\text{ 25} \\ (-4)^2+(-2)^2\text{ }\ne\text{ 25} \\ 16\text{ + 4 }\ne\text{ 25} \\ 20\text{ }\ne\text{ 25} \end{gathered}[/tex]Since LHS is not equal to RHS then the point (-2, 11) is not on the circle.
