The equation of the line in slope-intercept form is:
[tex]y\:=\:\frac{-10}{7}x-\frac{45}{7}[/tex]Step-by-step explanation:
Given the points
(-8, 5)(-1, -5)Finding the slope
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-8,\:5\right),\:\left(x_2,\:y_2\right)=\left(-1,\:-5\right)[/tex]
[tex]m=\frac{-5-5}{-1-\left(-8\right)}[/tex]
[tex]m=-\frac{10}{7}[/tex]
We know the slope-intercept form of the line equation is
[tex]y = mx+b[/tex]
where m is the slope and b is the y-intercept
substituting m = -10/7 and (-8, 5) in the slope-intercept form to determine the y-intercept
[tex]5\:=\:\frac{-10}{7}\left(-8\right)+b[/tex]
[tex]\frac{80}{7}+b=5[/tex]
[tex]b=-\frac{45}{7}[/tex]
now substituting m = -10/7 and b = -45/7 in the slope-intercept form
[tex]y = mx+b[/tex]
[tex]y\:=\:\frac{-10}{7}x+\left(-\frac{45}{7}\right)[/tex]
[tex]y\:=\:\frac{-10}{7}x-\frac{45}{7}[/tex]
Thus, the equation of the line in slope-intercept form is:

We all know that velocity is the directional speed of a object in motion as an indication of its rate of change in position as observed from a particular frame of reference and as measured by a particular standard of time and it can be written as Velocity = [tex]\frac{S}{T}[/tex]
So position at N: V= [tex]\frac{100}{4}[/tex]= 25km/h
So position at M: [tex]V= \frac{80}{5}[/tex] = 16Km/h
So position at O: x[tex]V= \frac{80}{5}[/tex] = 12Km/h
So as we all know 12<16<25
So O cyclist is slowest one with 12Km/h speed

Levi must score 220 in Exam B in order to do equivalently well as he did in Exam A
How well must Levi score on Exam B in order to do equivalently well as he did on Exam A?The given parameters are:
Exam A
Score = 710
Mean = 700
Standard deviation = 25
Exam B
Mean = 200
Standard deviation = 50
The z-score is calculated as
z = (Score - Mean)/Standard deviation
For exam A, we have
z = (710 - 700)/25
z = 0.4
For exam B, we have
z = (Score - 200)/50
Substitute z = 0.4 in z = (Score - 200)/50
0.4 = (Score - 200)/50
This gives
Score - 200 = 20
Add 200 to both sides
Score = 220

Step-by-step explanation:
Pre-SolvingGivenWe are given the points (2, -3), and (6,4), and we want to find the slope through these 2 points.
FormulasThe formula for the slope (m) is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points.

x(2x+5) = 3 and 2x²+5x = 3 are equivalent algebraic expression.
Equivalent expressions are those expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value(s) for the variable(s). They are same but looks different.
Given that, x(2x+5) = 3 and 2x²+5x = 3 and we have to conclude how both expressions are related to each other.
Let's procced to solve this.
x(2x+5) = 3 ..............(1)
2x²+5x = 3 ...............(2)
Now, solving equation (1), we get
x(2x+5) = 3 ⇒2x²+5x = 3, which is equation (2)
So, when we solve equation (1), we get equation (2) and vice-versa.

in a balloon it was notices that the pressure, in atmosphere (atm), was inversely proportional to the square root of the height, in metres. when the balloon was at the height of 25m,tge pressure was 1.44atm. what was the pressure at a height of 9m?
Answers
It was discovered that the pressure in atmospheres (atm), when applied to a balloon, was inversely related to the height in meters, squared root. The pressure was 1.44 atm when the balloon was 25 meters height in the air. What was the pressure like at a 9-meter height?
The pressure is 2.4 atm when the height is 9m.
Inversely proportion means when one variable is directly proportional to the reciprocal of the other, there is an inverse fluctuation between the two variables. In other words, the two variables' product has a fixed value. Therefore, as one variable rises, the other falls.
Here, We take pressure of atmosphere as P and the height of the balloon as H.
Given that, The pressure of atmosphere was inversely proportional to the square root of the height.
We write this as [tex]P[/tex]∝[tex]\frac{1}{\sqrt{H} }[/tex].
Taking constant of the proportionality as k.
[tex]P[/tex]=[tex]\frac{k}{\sqrt{H} }[/tex].
We have, The pressure was 1.44 atm when the balloon was 25 meters height in the air.
P=1.44 and H=25
[tex]1.44=\frac{k}{\sqrt{25} }[/tex].
[tex]1.44=\frac{k}{5}[/tex]
[tex]k=5\times1.44[/tex]
[tex]k=7.2[/tex]
Now [tex]P=\frac{7.2}{H}[/tex]
We have to find If H is 9m then what is P?
[tex]P=\frac{7.2}{\sqrt{9} }[/tex]
[tex]P=\frac{7.2}{3}[/tex]
