what the person above me said is correct :)
Step-by-step explanation:
Answer:
Both inequalities use the division property to isolate the variable, y. When you divide by a negative number, like –7, you must reverse the direction of the inequality sign. When you divide by a positive number, like 7, the inequality sign stays the same. The solution to the first inequality is y > -23, and the solution to the second inequality is y <>

A bridge is 10 m above a railroad track and at right angles to it. A train is running at the rate of 20 m/s passes under the center of the bridge at the same instant that a car running 15 m/s reaches that point. How rapidly are they separating 3 seconds later?
The time taken that should be rapidly are distinct 3 seconds later should be considered as 24.78 m/s.
Calculation of the time taken:Here the point should be considered directly under the center of the bridge as the origin
Here
x = 20t, y = 15t, z = 10
let us assume s be the distance between them at time t,
So it be like
[tex]s^2 = (20t)^2 + (15t)^2 + 10^2 = 625t^2 + 100[/tex]
2s ds/dt = 1250t
ds/dt = 625t/s
Now at the time when
t = 3,
[tex]s = \sqrt (625*9+100)[/tex] = 75.6637
So,
ds/dt = [tex]625*3/75.6637[/tex] = 24.78 m/s

Answer: 24000
Step-by-step explanation: 294 divided by 98 is 3, 8000 x 3 = 24000
Write an equation in the form y=Mx+b to model the given representation
Answer:
y= 20x +30
Step-by-step explanation:
y - intercept of the graph is 30
Slope of the graph is [tex]\frac{20}{1}[/tex]
Answer:
y = 20x + 30
Step-by-step explanation:
y=mx+b
b value = y-intercept, so you find where the line crosses the y-axis.
Find point at (0,30); b = 30
m value = rise/run (rise over run) (y/x)
find the next point that the graph intersects at and count add to it to find 30.
the closest point is at (-1,10)
go back to rise/run
30-10 = 20
0-(-1) = 1
20/1 =20 is your m value
plug m value and b value into equation to form your line.
y=20x+30

How can knowing the slope and y-intercept help you graph an equation?
Answer:
To graph the equation of a line, we plot at least two points whose coordinates satisfy the equation, and then connect the points with a line. We call these equations "linear" because the graph of these equations is a straight line.There are two important things that can help you graph an equation, slope and y-intercept.SlopeWe're familiar with the word "slope" as it relates to mountains. Skiers and snowboarders refer to "hitting the slopes." On the coordinate plane, the steepness, or slant, of a line is called the slope. Slope is the ratio of the change in the y-value over the change in the x-value. Carpenters and builders call this ratio the "rise over the run." Using any two points on a line, you can calculate its slope using this formula.A red die is tossed and then a green die is tossed. What is the probability that the red die shows a six or the green shows a six? Hint: The two events are not mutually exclusive. So to the find probability of the union, Use: P(A or B)= P(A) + P(B) - P(A and B)

Determine the domain and range of the given function.
The domain is
.
The range is
.
Answer:
the domain or set of departure of a function is the set into which all of the input of the function is constrained to fall.2. The Range is the difference between the lowest and highest values. Example: In {4, 6, 9, 3, 7} the lowest value is 3, and the highest is 9. So the range is 9 − 3 = 6. It is that simple!
The domain is
✔ all real numbers
The range is
✔ all real numbers greater than or equal to –2

What is the value of n in the equation (4^3)^6 = 4^n
pls help
Answer:
Step-by-step explanation:
You can solve this by applying the fact that when an exponent is applied on top of a base raised to another exponent, those exponents can be multiplied:
Let's solve it:
[tex](4^3)^6 = 4^n\\4^{18} = 4^n\\n = 18[/tex]
