RS ≈ 5.39
Step-by-step explanation:
Calculate the length using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = R(- 2, 6) and (x₂, y₂ ) = S(- 4, 1)
RS = [tex]\sqrt{(-4+2)^2+(1-6)^2}[/tex]
= [tex]\sqrt{(- 2)^2+(-5)^2}[/tex]
= [tex]\sqrt{4+25}[/tex]
= [tex]\sqrt{29}[/tex]
≈ 5.39 ( to 2 dec. places )

Consider this equation: 9x - 7 - 3x + 9 = x + 7 + 5x + 9. How many solutions does this equation have?
Answers
Step-by-step explanation:
9x - 7 - 3x + 9 = x + 7 + 5x + 9
6x + 2 = 6x + 16
2 = 16
Since 2 = 16 is false, there exist no real solutions for x.
Final Answer: No Solution. The equation would have 0 solutions.
Steps/Explanations:
Hey there! The answer is No Solution because -7 = 7. If 7 = 7, then it would be true and have one solution, which is not the case here.
Step 1: You should cancel [tex]9[/tex] on both sides.
[tex]9x - 7 - 3x = x + 7 + 5x[/tex]
Step 2: Simplify [tex]9x - 7 - 3x[/tex] to [tex]6x - 7[/tex].
[tex]6x - 7 = x + 7 + 5x[/tex]
Step 3: Simplify [tex]x + 7 + 5x[/tex] to [tex]6x + 7[/tex].
[tex]6x - 7 = 6x + 7[/tex]
Step 4: You'll need to cancel [tex]6x[/tex] on both sides.
[tex]- 7 = 7[/tex]
Step 5: Since [tex]-7 = 7[/tex] is false, there would be no solution.
No Solution

Answers
Step-by-step explanation:
Let P be price after t year . From the formula of compounding
P = 9 (1.015)^t
Taking log to the base e on both sides
ln P = ln 9 + t ln 1.015
= (2.197 + .0149t )
P = e^{(2.197+.0149t)}

What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4y = 6 is an equation.
2x = 4 is an equation.
4x - 6x + 6x = 6 is an equation.
We have,
x - y = 4 _____(1)
4x + y = 1 _____(2)
From (1) we get,
x = 4 + y ____(3)
Putting (3) in (2) we get,
4x + y = 1
4 (4 + y) + y = 1
16 + 4y + y = 1
16 + 5y = 1
Subtract 16 on both sides.
5y = 1 - 16
5y = -15
Divide both sides by 5.
y = -3
Now,
Putting y = -3 in (3) we get,
x = 4 + y
x = 4 - 3
x = 1
Thus,
The value of x and y is 1 and -3.

A truck driver has to make a delivery at a location that is 230.2 miles away. She drives an average of 55 miles each hour for 3.25 hours. If the truck driver continues at the same speed, will she make it to the location in the next hour?
and how many does she or he have to go
Answers
Answer:
The driver will make it to the location in the next hour
Step-by-step explanation:
First, find how many miles they traveled in 3.25 hours, by multiplying 55 by 3.25:
55(3.25)
= 178.75
Then, add 55 to this to see if the driver will make it in the next hour:
178.75 + 55
= 233.75
Since this is greater than 230.2, this means they will make it to the location.
So, the driver will make it to the location in the next hour.
Answer:
Yes
Step-by-step explanation:
Since the truck driver is going at an average speed of 55 miles per hour and has already driven for 3.25 hours that means she has already covered a distance of ...
55 * 3.25 = 178.75 miles
If she continues at the same speed and travels for one more hour that means that she would cover another 55 miles which would put her at a total distance of ...
178.75 + 55 = 233.75 miles
Therefore, the answer would be Yes she would arrive at her location. ;)

Answer:
The diagram of the plotting point [tex]\left(3\frac{1}{2},\:2\frac{3}{4}\right)=\left(3.5,\:2.75\right)[/tex] is attached below.
Step-by-step explanation:
Given the points
[tex]\left(3\frac{1}{2},\:2\frac{3}{4}\right)[/tex]
as
[tex]3\frac{1}{2}=\frac{7}{2}=3.5[/tex]
[tex]2\frac{3}{4}=\frac{11}{4}=2.75[/tex]
so the point can be visualized as:
[tex]\left(3\frac{1}{2},\:2\frac{3}{4}\right)=\left(3.5,\:2.75\right)[/tex]
Now, we can check the point x = 3.5, and determine the corresponding value y = 2.75 and plot the point at the location (x, y) = (3.5, 2.75)

A gum tree reached a height of 150 ft in 15 years. Cathy and Darla write different equations to find the yearly average growth g of the tree. Cathy writes 15g = 150. Darla writes 150/15 = g. Do these equations have the same solution? Explain.
Answers
Answer:
Yes, they have the same answer because because 150/15 = 10 and in the equation 15g = 150, you have to solve it by dividing 150 by 15 which gets 10. Therefor, they are the same.
Step-by-step explanation:
Answer: They have the same solution.
Step-by-step explanation: 15g=150 has an answer of 10 ft. (divide 150 by 15 to get g alone.) 150/15=g has an answer of 10 as well. (Simplify to find g.)

Answers
Answer:
A.) 20x + 2y = 500
B.) y-intercept = 250; its meaning is how many boxes of pencils they started with.
C.) x-intercept = 25; How many T-shirts they can sell at most
Step-by-step explanation:
2y - 500 = -20x
20x + 2y - 500 = 0
20x + 2y = 500
y-intercept = 250; its meaning is how many boxes of pencils they started with.
20x + 2y = 500
20(0) + 2y = 500
2y = 500
2y/2 = 500/2
y = 250
x-intercept = 25; How many T-shirts they can sell at most
20x + 2y = 500
20x + 2(0) = 500
20x = 500
20x/20 = 500/20
x = 25
if the length of two sides of a triangle are 7 and 10 the length of the third side may be
A. 1
B.3
C.2
D.4
explain
Answers
Answer:
D. 4
Step-by-step explanation:
Let's look at all the options first. All of the options are below 7 and 10, hence we can deduce that it is not the hypotenuse. Looking at 7 and 10, we see that 10 is the larger number, and hence we know that 10 is the hypotenuse.
Hence, as the other two sides added up in a triangle must be larger than the hypotenuse, the only available option is 4, since 4 + 7 = 11 > 10.
Hope this helped!

The population of bears in a national forest is changing according to the function N(t)=850(1.04)t , where t is the time in years, and N(t) is the number of bears. Which statement explains how the bear population is changing?
Answers
Answer:
The statement is that the population increases at a rate of 4% per year
Step-by-step explanation:
The function is given as;
N(t) = 850(1.04)^t
The general equation form for a representation as this is;
P = I(1 + r)^t
Where I is the initial value and P is the present value
r is the rate of increase
t is the time
Thus, we have that;
1 + r = 1.04
r = 1.04-1
r = 0.04
0.04 is same as 4/100 which is same as 4%
So the statement about how the population of bear is changing is that the population increases at a rate of 4% each year

Oy>X-2 and x+ 2y < 4
Oy>x-2 and x +2y<-4
Answers
Answer:
y > x - 2.
2*y + x < 4
The correct option is the third one.
Step-by-step explanation:
First let's find the red shaded part.
We can see that the shade is above the line, then we will have something like:
y > a*x + b
where a*x + b is the equation for the line.
a is the slope, and b is the y-intercept.
In the graph, we can see that the line intercepts the y-axis at y = -2, then we have:
b = -2
To find the slope we need two points of the line, we can use the points (0, -2) and (2, 0)
We know that for a line that passes through the points (x1, y1) and (x2, y2) the slope is:
a = (y2 - y1)/(x2 - x1)
Then for this line, the slope will be:
a = (0 - (-2))/(2 - 0) = 2/2 = 1
Then the equation for this line is:
1*x - 2
And the inequality is:
y > x - 2.
Now for the blue one, the shaded part is below the line, then we will have:
y < a*x + b
In this case, the y-intercept is y = 2.
And we can see that this line passes through the points (0, 2) and (4, 0)
Then the slope is:
a = (0 - 2)/(4 - 0) = -2/4 = -1/2
Then this inequality is:
y < (-1/2)*x + 2
If we rewrite this as the ones shown in the options, we have:
y < (-1/2)*x + 2
2*y < -x + 2*2
2*y + x < 4
Then the two inequalities are:
y > x - 2.
2*y + x < 4
Then the correct option is the third one:
The system of linear inequalities y > x - 2 and x + 2y < 4 is represented by the graph
InequalityInequality is an expression that shows the non equal comparison of two or more numbers and variables
Given the inequalities y > x - 2 and x + 2y < 4, plotting the two inequalities using the geogebra online graphing tool.
