Are these equations equivalent?
0.8x + 3= 1.8x and 2x =6
Answers
Answer:
Yes
Step-by-step explanation:
0.8x + 3 = 1.8x
3 = 1.8x - 0.8x
x = 3
And:
2x = 6
dividing both sides by 2:
x = 3.
hence the two equations are equivalent since they give the same answer.

Answers
I think it could represent the 100-yard dash. The graph represents distance versus time, which is a common way to graphically display motion.
What is graph?A graph is a visual representation of data that displays the relationship between two or more variables. Graphs can be used to illustrate numerical information in a clear and concise way, making it easier to understand and analyze complex sets of data. Graphs can be created using various types of software or by hand, and there are many different types of graphs, including line graphs, bar graphs, scatter plots, pie charts, and more.
Here,
The vertical axis represents the distance, and the horizontal axis represents time. The line on the graph shows how the distance traveled changes with respect to time.
The graph also shows that the runner covers a certain distance in a specific amount of time, which is a fundamental concept in physics. In the case of the 100-yard dash, the graph shows how the runner covers 100 yards in a certain amount of time.
Overall, the graph displays the key characteristics of motion and can be used to analyze and compare the performance of athletes in various sports.

Convert the rectangular coordinates (5,−5√3) to polar form. Let r>0 and 0≤θ<2π.
Enter your answer by filling in the boxes. Enter coordinates as simplifed fractions or radicals in simplest form.
( , )
Answers
Answer:
(10, 5π/3)
Step-by-step explanation:
To convert rectangular coordinates (5, -5√3) to polar form, we can use the following formulas:
r = √(x^2 + y^2)
θ = arctan(y/x)
Substituting the given values, we get:
r = √(5^2 + (-5√3)^2) = √(25 + 75) = √100 = 10
θ = arctan((-5√3)/5) = arctan(-√3) = -π/3
Note that the value of θ is in the fourth quadrant, which corresponds to a negative angle. However, we need to express the angle θ in the range 0 ≤ θ < 2π. To do this, we can add 2π to the angle if it is negative:
θ = -π/3 + 2π = (5π/3)
Therefore, the rectangular coordinates (5, -5√3) in polar form are (10, 5π/3).

6 plates and 5 cups cost 23.80 dollars. 7 plates and 6 cups cost 28.00. Each plate costs the same as the other plates, each cup costs the same as the other cups. What is the cost of 1 plate? What is the cost of 1 cup?
Answers
Plates = p
6p + 5c = 23.80 ==> multiply by 6 ==> 36p + 30c = 142.80
7p + 6c = 28.00 ==> multiply by 5 ==> 35p + 30c = 140.00
Now use algebra to have the 30c be on one side and the rest on the other:
36p + 30c = 142.80 | -36p
30c = 142.80 - 36p
35p + 30c = 140.00 | -35p
30c = 140.00 - 35p
Now set them equal to each other about the 30c:
142.80 - 36p = 140.00 - 35p
Use algebra to solve for p:
142.80 - 36p = 140.00 - 35p | +36p
142.80 = 140.00 + p | - 140
2.80 = p
Go back to one of the "30c" equations and plug in the value for p:
30c = 140 - 35p
30c = 140 - 35(2.80)
30c = 140 - 98
30c = 42 | /30
c = 42/30
c = 1.4
Plates are $2.80
Cups are $1.40

Consider this function.
f(x) = |x – 4| + 6
If the domain is restricted to the portion of the graph with a positive slope, how are the domain and range of the function and its inverse related?
Answers
If we restrict the domain of the function to the portion of the graph with a positive slope, the domain of the inverse function will be the range of the original function for values of x greater than 4, and its range will be all real numbers greater than or equal to 4.
The given function f(x) = |x – 4| + 6 is a piecewise function that contains an absolute value. The absolute value function has a V-shaped graph, and the slope of the graph changes at the point where the absolute value function changes sign. In this case, that point is x=4.
If we restrict the domain of f(x) to the portion of the graph with a positive slope, we are essentially considering the piece of the graph to the right of x=4. This means that x is greater than 4, or x>4.
The domain of the inverse function, f⁻¹(x), will be the range of the original function f(x) for values of x greater than 4. This is because the inverse function reflects the original function over the line y=x. So, if we restrict the domain of f(x) to values greater than 4, the reflected section of the graph will be the range of f⁻¹(x).
The range of f(x) is all real numbers greater than or equal to 6 because the absolute value function always produces a positive or zero value and when x is greater than or equal to 4, we add 6 to that value. The range of f⁻¹(x) will be all real numbers greater than or equal to 4, as this is the domain of the reflected section of the graph.

The solutions to the given linear equations found using the properties of the geometric figures are;

13. The midpoint of AB is the point (-5, 1)
14. R(-3, 8)
15. JL = 22•x + 10
16. CD = 15
How can the measure and coordinates of the given geometric figures be found?9. According to segment addition postulate, we have;
RT = RS + ST
RS = 23 - 2•x
ST = 9•x - 5
Which gives;
39 = 23 - 2•x + 9•x - 5 = 7•x + 18
7•x = 39 - 18 = 21
x = 21/7 = 3
x = 3
RS = 23 - 2•x
RS = 23 - 2×3 = 17
RS = 1710. LN = 6•x - 5
LM = x + 7
MN = 3•x + 20
LN = LM + MN
Which gives;
LN = x + 7 + 3•x + 20 = 4•x + 27
LN = 6•x - 5
Therefore;
6•x - 5 = 4•x + 27
6•x - 4•x = 27 + 5 = 32
2•x = 32
x = 32/2 = 16
x = 16
MN = 3•x + 20
Which gives;
MN = 3×16 + 20 = 68
MN = 6811. The points are;
X(-9, 2), Y(5, -4)
Using Pythagorean theorem, we have;
XY = √((5 - (-9))²+(-4 - 2)²) ≈ 15.23
XY ≈ 15.2312. The coordinates of the points are;
M(-1, 2), and N(4, 0)
Which gives;
MN = √((4 - (-1))² + (0 - 2)²) ≈ 5.39
MN ≈ 5.3913. The points are;
(-3, 8), (-7, -6)
The midpoint is therefore;
((-3+(-7))/2, (8+(-6))/2) = (-5, 1)
The midpoint of AB is the point (-5, 1)14. The points are;
P(11, -2), Q(4, 3)
The midpoint of the PR = Q
Which gives;
((11+x)/2, (-2+y)/2) = (4, 3)
(11+x)/2 = 4
x = 2×4 - 11 = -3
(-2+y)/2 = 3
(-2+y) = 3×2 = 6
y = 6 + 2 = 8
The coordinates of the point R is therefore;
R(-3, 8)15. JK = 8•x + 11
KL = 14•x - 1
JL = 8•x + 11 + 14•x - 1 = 22•x + 10
JL = 22•x + 10
16. CD = CE
Therefore;
x + 6 = 4•x - 21
4•x - x = 21 + 6 = 27
3•x = 27
x = 27/3 = 9
x = 9
CD = 9 + 6 = 15
