The equation of a line that has a slope of 1/5 and passes through the point (3, 10) is y= (1/5)x + (47/5).
What is the general equation of a straight line?The general equation of a straight line is -
y = mx + c
{m} - slope.
{c} - intercept along the y - axis.
Given is that a line has a slope of 1/5 and passes through the point (3, 10)
We can write the slope of the line as -
m = 1/5
For the point (3, 10), we can write -
y = (1/5)x + c
10 = (1/5) x 3 + c
c = 10 - 3/5
c = 47/5
Therefore, the equation of a line that has a slope of 1/5 and passes through the point (3, 10) is y= (1/5)x + (47/5).

Use the graph or the formula to write the equation of the line in a slope intercept form
The equation of line passing through (-9,-10) and(7,-3) will be y = (7/16)x - 1
What is slope?Slope is a measure of the steepness of a line, and it is also known as the "gradient." It is a ratio of the vertical change (rise) to the horizontal change (run) between two points on a line. It is often represented by the letter "m" in the slope-intercept form of a linear equation, y = mx + b, where m is the slope and b is the y-intercept (the point where the line crosses the y-axis).
What is the formula to find the equation of line given the two points?The formula to find the equation of a line given two points is:
y - y1 = m(x - x1)
where (x1,y1) and (x2,y2) are the coordinates of the two points on the line, and m is the slope of the line, which can be calculated using the formula:
m = (y2 - y1) / (x2 - x1)
m = (y2 - y1) / (x2 - x1)
where (x1,y1) and (x2,y2) are the coordinates of the two points.
so the slope m = (-3 - (-10)) / (7 - (-9)) = 7/16
We can use point slope form to get the equation of the line passing through the two points:
y - y1 = m(x - x1)
so the equation of the line is y - (-10) = (7/16)(x + 9)
=> y = (7/16)x + (-10) + (9 * 7/16)
=> y = (7/16)x - 1

Lauren throw a ball with an initial velocity of 40 feet per econd. The equation for the of the ball i h =- 16t? 40t 5, where h repreent the height in feet and t repreent the time in econd. When will the ball reach a height of 3 feet?
The ball will reach a height of 3 feet at t = 5/4 seconds.
To find the time (t) when the ball reaches a height of 3 feet, we need to use the equation for the height of the ball: h = -16 [tex]t^2[/tex] + 40t + 5
We are given that the height of the ball is 3 feet, so we can set up the equation:
3 = -16[tex]t^2[/tex] + 40t + 5
Then we can solve for t by isolating t on one side of the equation and then solving for t:
3 = -16[tex]t^2[/tex] + 40t + 5
-5 = -16[tex]t^2[/tex] + 40t
16[tex]t^2[/tex] - 40t - 5 = 0
We can factor the left side of the equation:
(4t - 5)(4t + 1) = 0
So we have two possible solutions:
t = 5/4 or t = -1/4
However, the time cannot be negative, so the only valid solution is t = 5/4.
So the ball will reach a height of 3 feet at t = 5/4 seconds.

In Scrabble, there are a certain number of each of the vowel: A-9, E-12, I-9, O-8, U-4. You decided to place only the vowel in a bag to conduct an experiment of drawing and replacing the letter back in the bag. The experiment' outcome wa a follow:
E, I, A, E, E, A, I, O, U, U, A, A, O, O, E
Which vowel' theoretical probability wa cloet to the experimental probability?
A and E are the vowels that theoretical probability was closet to the experimental probability.
The probability is 0.1685%
Probability:
Probability defines the probability of an event occurring. There are many real world situations where we need to predict the outcome of an event. We may or may not be certain about the outcome of an event. In such cases, I say that this event may or may not occur. Probability in general has excellent applications for making probability-based predictions in games and economics, and it also has widespread applications in this emerging field of artificial intelligence. The probability of an event can be calculated by simply dividing the number of favorable outcomes by the total number of possible outcomes using the probability formula. The value of the probability that an event will occur can range from 0 to 1. This is because the preferred number of outcomes can never exceed the total number of outcomes. Also, the resulting favorable number can never be negative. The formula for calculating the probability of a
event is:
probability (event) = favorable outcome/total outcome
Now,
According to the Question:
N vowels = N(A) + N(E) + N(I) + N(O) + N(U)
=9 + 12 + 9 + 8 + 4
=42
The total number of letters is:
1×5+2×10+3×1+4×4+6×3+8×1+9×2+12×1=100
This is because dragging the tile reduces the number of vowels and the total number of letters.

198.95 feetHow to measure the distance PRThe length of line PR is calculated using the knowledge of similar triangles
While similar triangles is a term used in geometry to mean that the respective sides of the triangles are proportional and the corresponding angles of the triangles are congruent.
Hence assuming the corresponding angles of the triangle are congruent then the side should be in proportions
Examining the figure shown, the pair of equivalent sides are
PO and OC, PR and RE,
The solution is worked out using sides PO and OC, PR and RE,
PO / OC = PR / RE
let PR be equal to y such that PO = 140 + y
(140 + y) / 230 = y / 135
cross multiplying
135(140 + y) = 230y
Expanding
18900 + 135y = 230y
collecting like terms
18900 = 230y - 135y

Is 8 15 17 a right angle triangle?
No, 8 15 17 is not a right angle triangle. A right angle triangle is a triangle in which one of the three angles is equal to 90 degrees.
To determine if a triangle is a right angle triangle, we can use the Pythagorean theorem. This states that in a right angle triangle, the sum of the squares of the two shorter sides (a and b) will equal the square of the longest side (c).
In this case, the length of the sides are 8, 15 and 17. We can calculate the sum of the squares of the two shorter sides, which is 8² + 15² = 144 + 225 = 369. However, the square of the longest side (17²) is 289. Since 289 is not equal to 369, this means that 8 15 17 is not a right angle triangle.

To graph y 3x 3, we can first graph y = 3x. To do this, we can pick any two points along the line and plot them. For example, if we choose (0,0) and (1,3), the line would look like this:
(0,0) -------------------------- (1,3)
Now, to graph y 3x 3, we want to move the line 3 units down. Therefore, the new points that we plot should be (0,-3) and (1,0). The graph should look like this:
