Answer:
so first you would subtract the 10x from the one side so the equation now looks like
2y = -10x + 40
y = −5x + 20
im not sure if this is what you mean but this is how i interpreted it.
if right pls brainly
Which mapping diagram represents a function ? Would it be D?
Answer:
D
Step-by-step explanation:
Mathematically , for us to have a function, no 2 y values must have a single x value
Although, 2 x-values can have a single y value
The y values called the output values are listed on the right
The x values called the input values are listed on the left
So out of the options, with the given definition above, the one that represents a function is the option D
The point P(x, y) lies on the terminal side of an angle 0 = –60° in standard position. What are the signs of the values of x and y?
Answer:
X is positive
Y is negative
Step-by-step explanation:
Just take the cos of angle - 60 for X
and also take the sin of angle - 60 for Y
You will find x positive, and y negative
A coat at a store is originally priced at $54.99. The store marks the price down to $32.99. To the nearest percent, what is the percent markdown of the coat?
Answer:
66.6%
Step-by-step explanation:
Step one
given
A coat at a store is originally priced at $54.99
The store marks down the price down to $32.99
Required
the percent decrease
Step two:
the percent decrease= change in price/ old price*100
the percent decrease= 54.99-32.99/54.99*100
the percent decrease= 22/ 32.99*100
the percent decrease= 0.666*100
the percent decrease= 66.6%
Find the volume of the composite figure below.
Answer:
Volume of composit figure= 4834.14 cm^3
Step-by-step explanation:
here's your solution
=> Radius of hemisphere = 9 cm
==> volume of hemisphere = 2/3πr^3
==> volume of hemisphere = 2/3*22/7* 9^3
==> volume = 1526.04 cm^3
=> Radius of cylinder = 9 cm
=> Height of cylinder = 13 cm
==> volume of cylinder = πr^2h
==> volume of cylinder = 22/7*9^2*13
==> volume of cylinder = 3,308.1 cm^3
Volume of composit figure = 1526.04 + 3308.1
= 4834.14 cm^3

Given P(A) 0.3, P(B) = 0.43 and P(ANB) = 0.249, find the value of
P(AUB), rounding to the nearest thousandth, if necessary.
Answer:
0.481
Step-by-step explanation:
P(A U B) = P(A) + P(B) - P(A∩B)
= 0.3 + 0.43 - 0.249
= 0.73 - 0.249
= 0.481

A. Their rates of change differ by 2. B. Their rates of change differ by 4. C. Function M has a greater rate of change than Function P. D. Function M and Function P have the same rate of change.
Answer:
(a) Their rates of change differ by 2
Step-by-step explanation:
Given
See attachment for functions M and P
Required
Determine what is true about the rates of M and P
First, we calculate the slope (i.e. rate) of both functions.
Slope is calculated as:
[tex]m = \frac{y_2 -y_1}{x_2 - x_1}[/tex]
From the table of M, we have:
[tex](x_1,y_1) = (-2,-9)[/tex]
[tex](x_2,y_2) = (2,11)[/tex]
So, the slope is:
[tex]m_M = \frac{11 --9}{2--2}[/tex]
[tex]m_M = \frac{20}{4}[/tex]
[tex]m_M = 5[/tex]
For function P, we have:
[tex]y = 7x + 9[/tex]
A function is represented as:
[tex]y = mx + b[/tex]
Where:
[tex]m = slope[/tex]
So, by comparison:
[tex]m_P = 7[/tex]
At this point, we have:
[tex]m_M = 5[/tex] --- Slope of M
[tex]m_P = 7[/tex] --- Slope of P
Only option (a) is true because both slopes differ by 2. i.e. 7 - 5 = 2
Other options are not true

Find the exact values of csc and sec
Answer:
cosec theta = 5/4
sec theta = 5/3
Step-by-step explanation:
Given that;
cot θ = 3/4
1/tanθ = 3/4
tanθ = 4/3
since tanθ = opp/adj
opp = 4
adj = 3
hyp^2 = 4^2 + 3^2
hyp^2 = 16+9
hyp^2 = 25
hyp = √25
hyp = 5
sin theta= opp/hyp
sin theta = 4/5
cosec theta = 1/sin theta
cosec theta = 1/(4/5)
cosec theta = 5/4
Get sec theta;
sec theta = 1/costheta
sec theta = 1/(3/5)
sec theta = 5/3
Stephan has a piece of wood that measures 18 inches long and 12 inches wide. He wants to make a tray with sides 2 inches high. Maurice says that he can make a tray that has a base measuring 10 1/2 inches by 10 1/2 inches. Is he correct?
Answer:
he isn't
Step-by-step explanation:
The wood has dimensions of 18 x 12
If He wants the tray to have a height of 2, subtract 2 x 2 from both the length and the width
18 - 4 = 14
12 - 4 = 8
the highest possible dimensions of the tray can be 14 x 8
10 1/2 x 10 1/2 is greater than 14 x 8. so he is not correct

How do I solve this arithmetic sequence?
Answer:
The 16ᵗʰ term of this sequence is 82
Step-by-step explanation:
Here,
First Term = a₁ = 9
Common Difference = (d) = 2
Now, For 16ᵗʰ term, n = 16
aₙ = a + (n - 1)d
a₁₆ = 7 + (16 - 1) × 2
a₁₆ = 7 + 15 × 5
a₁₆ = 7 + 75
a₁₆ = 82
Thus, The 16ᵗʰ term of this sequence is 82

What is the Pythagorean Theorem?
Pythagorean theorem
in right angled triangles there is a relationship that governs the length of the tree sides. if we knows the length of any two sides, the third side maybe calculated by the use of the Pythagorean theorem.
this theorem states that the square on the hypotenuse of a right angled triangle is equal to the sum of the squares on the remaining two sides.

What is translation?A translation in mathematics does not turn a shape; instead, it moves it left, right, up, or down. They are congruent if the translated shapes (or the image) seem to be the same size as the original shapes. They've simply shifted in one or more directions.
Given that the functions are f(x) = x³ and g(x) = ( x + 4 )³. The translation of the function will be at 4 units to the left.
When the functions are plotted on the graph the translation is seen to the left of the origin at the coordinate (-4,0).

The students in two 7th grade classes were asked, "How many text messages did they send over the past weekend?" The data was collected and a dot plot was created for each class. For what values do class A's distribution and class B's distribution overlap?
Answer:
2, 3, 4, and 5
Step-by-step explanation:
Class A and Class B's distributions overlap for the values of 2, 3, 4, and 5. This can be seen in the dot plot below since all of these values have inputs on both of the class' distributions. Values 0 and 1 are not included because they only have inputs for Class A, while values 6 and 7 are not included because they only have inputs for Class B. In order for the values to overlap they need to be included in both class distributions.
Answer:
2,3,4,5
Step-by-step explanation:
Class A and Class B distribution overlap at 2,3,4 and 5 because if you look at both graphs you can see how they both overlap each other.

Rewrite the quadratic expression in faceted format: f left parenthesis x right parenthesis equals negative x squared minus 4 x plus 21
Answer:
[tex]f(x)=-x^2-4x+21[/tex]
Step-by-step explanation:
The given equation is :
f left parenthesis x right parenthesis equals negative x squared minus 4 x plus 21.
We need to rewrite this equation in faceted format.
The general form of a quadratic equation is given by :
[tex]f(x)=ax^2+bx+c[/tex]
We have,
a = -1, b = -4 and c = 21
Substitute all the values,
[tex]f(x)=-x^2-4x+21[/tex]
So, the required equation is equal to [tex]f(x)=-x^2-4x+21[/tex].
