What is the slope of the line on this graph?
Enter your answer in the box.
to get the slope of any straight line, we simply need two points off of it, let's use those in the picture below
[tex](\stackrel{x_1}{-1}~,~\stackrel{y_1}{3})\qquad (\stackrel{x_2}{2}~,~\stackrel{y_2}{-3}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-3}-\stackrel{y1}{3}}}{\underset{run} {\underset{x_2}{2}-\underset{x_1}{(-1)}}} \implies \cfrac{-6}{2 +1} \implies \cfrac{ -6 }{ 3 } \implies \text{\LARGE -2}[/tex]
Answer:
The slope is 2
Step-by-step explanation:
To find the slope you divide the rise by the run. Rise being how many units it goes up or down) (run being how many units it goes to the side).
In this case the rise is -2 and the run is -1.
See in the picture, for every 2 units the line goes down, it moves one unit to the right.
so, -2/-1= 2

Find the values of x and y.
Answer:
x = 30y = 5Step-by-step explanation:
You want to know the values of x and y in the given figure.
Equilateral triangleThe left-side triangle has angles marked as congruent. Hence it is an equilateral triangle, which also has congruent sides.
8y = 40
y = 40/8 = 5
Isosceles triangleThe angle at the middle of the longest line is supplementary to the adjacent angle in the equilateral triangle, hence is 120°.
The marked side length of 40 and the equilateral triangle side length of 40 mean the triangle on the right is an isosceles triangle with an a.pex angle of 120°. Its congruent base angles (x°) must be (180° -120°)/2 = 30°.
x° = 30°
The values of x and y are 30 and 5, respectively.

#SPJ1
Step-by-step explanation:
The given function is g(x) = 3x + 6.
Domain: The domain of a function is the set of all possible input values (x) for which the function is defined. Since the function is a linear equation, it is defined for all real values of x. Therefore, the domain of the function is: Domain: -∞ < x < ∞ Range: The range of a function is the set of all possible output values (y) that the function can produce. The slope of the given function is positive (3), so the function increases without bound as x increases.
Therefore, the range of the function is: Range: -∞ < y < ∞ x-intercept: The x-intercept of a function is the point at which the graph of the function intersects the x-axis. To find the x-intercept, we set y = 0 and solve for x. 0 = 3x + 6 -6 = 3x -2 = x Therefore, the x-intercept is (-2, 0).
So, the correct option is: Domain: -∞ < x < ∞; Range: -∞ < y < ∞; x-intercept (-2, 0).

Coin's family has driven 318 miles in 6 hours. If they continue at this rate how far will they travel during the next 4 hours. complete the proportional statement with the selections.
Hello,
I hope you and your family are doing well!
To solve this problem, you need to set up a proportion using the information given in the problem. Let x represent the number of miles the family will travel during the next 4 hours. The proportion will look like this:
318 miles / 6 hours = x miles / 4 hours
To solve for x, you can cross-multiply and solve the equation:
318 miles / 6 hours = x miles / 4 hours
6 hours * 318 miles = 4 hours * x miles
1848 miles = 4x miles
x = 462 miles
Therefore, if the family continues at the same rate, they will travel a total of 462 miles during the next 4 hours.

Answer:
(-5, 0)
|z| = 5
Step-by-step explanation:
Complex numbers can be represented on an Argand diagram.
The x-axis is called the real axis and the y-axis is called the imaginary axis.
The complex number z = x + iy is represented on the diagram by the point P(x ,y), where x and y are Cartesian coordinates.
Therefore, the complex number z = -5 can be represented on the Argand diagram by the point:
(-5, 0)The absolute value of a complex number is the magnitude of its corresponding vector.
For a complex number z = x + iy, the absolute value is given by:
[tex]|z|=\sqrt{x^2+y^2}[/tex]
Therefore, the absolute value of complex number z = -5 is:
[tex]\implies |z|=\sqrt{(-5)^2+(0)^2}[/tex]
[tex]\implies |z|=\sqrt{25+0}[/tex]
[tex]\implies |z|=\sqrt{25}[/tex]
[tex]\implies |z|=5[/tex]
Robin worked his 40 regular hours last week plus 20 overtime hours at the time-and-a-half rate. His gross pay was $16,203. What is his regular hourly rate?
Answer:
His rate is a whopping $231.47 per hour.
:)
Step-by-step explanation:
We can conclude that.
[tex]r*t_1=p_{reg}[/tex] is the gross pay from his regular hours.
[tex]1.5r*t_2=p_{ovt}[/tex] is the gross pay from his overtime hours.
So all together we can say
[tex](r*t_1)+(1.5r*t_2)=p[/tex]
We are looking for his hourly rate.
Lets solve for [tex]r[/tex].
Multiply the terms in the parenthesis.
[tex]rt_1+1.5rt_2=p[/tex]
Factor [tex]r[/tex] out of [tex]rt_1[/tex].
[tex]r(t_1)+1.5rt_2=p[/tex]
Factor [tex]r[/tex] out of [tex]1.5rt_2[/tex].
[tex]r(t_1)+r(1.5t_2)=p[/tex]
Factor [tex]r[/tex] out of [tex]r(t_1)+r(1.5t_2)[/tex].
[tex]r(t_1+1.5t_2)=p[/tex]
Divide each term in [tex]r(t_1+1.5t_2)=p[/tex] by [tex]t_1+1.5t_2[/tex] and simplify.
[tex]\frac{r(t_1+1.5t_2)}{t_1+1.5t_2} =\frac{p}{t_1+1.5t_2}[/tex]
Simplify the left side. Cancel the common factor of [tex]t_1+1.5t_2[/tex]
[tex]r=\frac{p}{t_1+1.5t_2}[/tex]
Now we have an equation to find his regular hourly rate.
We are given
[tex]p=16203[/tex]
[tex]t_1=40[/tex]
[tex]t_2=20[/tex]
Lets plug these numbers into our equation for [tex]r[/tex].
[tex]r=\frac{16203}{40+1.5*20}[/tex]
[tex]r=\frac{16203}{70}[/tex]
[tex]r=231.47[/tex]

There would be 52 atoms after 25 years and it would take 13 years for half the number of atoms to remain.
What is radioactive decay?We know that the term radioactive decay has to do with the break down of a substance to form the daughter nuclei of the particular element. In this case, we have the decay function of the element to be; A(t) =200e^-0.054t.
t is the time taken for decay.
Now in 25 years we would have;
A(t) =200e^-0.054(25)
A(t) = 52 atoms
The time that it would take for half of the original number to remain is obtained from;
100 = 200e^-0.054t
100/200 = e^-0.054t

If $900 is invested at 3%, compounded monthly, the future value S at any time t (in years) is given by the following.S = 900(1.0025)^12tHow long (in years) will it take for the amount to double? (Round your answer to one decimal place.)
Number of years it will take for the amount to double is 23 years
The principal amount = $900
The interest rate = 3%
The interest is compounded monthly
The given equation is
S = 900(1.0025)^12t
Where S is the final amount
t is the time period in years
The final amount is the double of principal amount
Final amount = 2 × 900
= $1800
Substitute the values in the equation
1800 = 900(1.0025)^12t
1.0025^12t = 1800/900
1.0025^12t = 2
Then value of t = ln(2) / 12ln (1.0025)

Be sure to:
1) Write the differential equation (use k for the constant of proportionality)
2)Solve the differential equation
3) Evaluate the solution at the specified value of the independent variable. (Round your answer to three decimal places.)
1) The differential equation is: dP/dt=kP
2) P(t)=8000[tex]e^{-0.28t}[/tex]
3) The solution at the specified value of the independent variable is 1490.991
What is meant by differential equation?In practical contexts, derivatives frequently represent the rates of change of physical quantities, and the differential equation establishes a relationship between the two. As a result of the frequent occurrence of these correlations, differential equations are widely employed in a wide range of disciplines, including engineering, physics, economics, and biology.
Only the simplest differential equations can be resolved explicitly, but many aspects of a given differential equation's solutions can be determined without doing an exact calculation.
1) The differential equation is: dP/dt=kP
Here k is the proportionality constant
2) Now, we have to solve the differential equation on dP/dt=kP
∫dP/P=∫kdt+lnP₀
lnP₀=kt+lnP₀

Value in mathematics can refer to a number of closely related ideas. A mathematical value can generally be any specific mathematical object. This is most frequently a number in elementary mathematics, such as a real number like or an integer like 42.
Depending on where it is in the number, each digit has a different value, which is referred to as value. We figure it out by multiplying the digit's place value by its face value. Place value plus face value equals value. Consider the number 45, for example. Here, the fourth digit is in the tens column.
If triangle is isosceles it means the two sides and angles are equal
∴ BC = AC
AC = 8 cm
A + B + C = 180
A = 180 - 70 -70
∠A = 40°
∠C = 70°
