d. 10 + 3у – 2 = 4у — у + 8
Answer:
3y+8=3y+8
Step-by-step explanation:
10+3y-2=4y-y+8
10+3y-2 combine 10 and -2 and you get 3y+8
4y-y+8 combine the 4y with the -y and you get 3y+8
3y+8=3y+8

Answer:
area = 220.5 ft²
Step-by-step explanation:
2(Length) + 2(10.5) = 63 feet
2L + 21 = 63
subtract 21 from each side of the equation:
2L = 42
divide both sides by 2:
L = 21 feet
area = L x W = 21 x 10.5 = 220.5 ft²
Answer:
A = 220.5 ft
Step-by-step explanation:
[tex]2(Length) + 2(10.5) = 63 feet\\[/tex]
[tex]2L + 21 = 63\\[/tex]
[tex]63 - 21[/tex]
[tex]2L = 42[/tex]
[tex]42/2[/tex]
L = 21 feet
[tex]A=l * w[/tex]
[tex]21 x 10.5 = 220.5 ft^{2}[/tex]

Answer:
42
Step-by-step explanation:
14/2= 7
21/3=7
6 x 7 = 42
2x1+0x2+3x3=3
4x1-3x2+7x3=5
8x1-9x2+15x3=10
solve the system using Gaussian or Gauss-Jordan elimination
[1] … … 2x₁ + 0x₂ + 3x₃ = 3
[2] … … 4x₁ - 3x₂ + 7x₃ = 5
[3] … … 8x₁ - 9x₂ + 15x₃ = 10
Since [1] is already free of x₂, you might as well start by eliminating x₂ from the other two equations. Add -3 times [2] to [3] :
-3 (4x₁ - 3x₂ + 7x₃) + (8x₁ - 9x₂ + 15x₃) = -3 (5) + 10
-12x₁ + 9x₂ - 21x₃ + 8x₁ - 9x₂ + 15x₃ = -15 + 10
-4x₁ - 6x₃ = -5
[4] … … 4x₁ + 6x₃ = 5
Now eliminate x₃ in [1] and [4]. Add -2 times [1] to [4] :
-2 (2x₁ + 3x₃) + (4x₁ + 6x₃) = -2 (3) + 5
-4x₁ - 6x₃ + 4x₁ + 6x₃ = -6 + 5
0 = -1
which is a contradiction. This means the system has no solution.

A nonlinear function Group of answer choices is a function with a slope that is not constant. is a concept that only applies to the case of a single or two explanatory variables since you cannot draw a line in four dimensions. makes little sense, because variables in the real world are related linearly. can be adequately described by a straight line between the dependent variable and one of the explanatory variables.
Answer:
is a function with a slope that is not constant.
Step-by-step explanation:
A linear function has a positive relationship and as such an increase in one variable (input variable) causes an increase in the other variable (output variable) i.e the variables are directly proportional. Thus, the graph of a linear function is a straight-line and its slope is always constant.
On the other hand, nonlinear function has a negative relationship and as such an increase in one variable (input variable) causes a decrease in the other variable (output variable) i.e the variables are inversely proportional.
This ultimately implies that, the graph of a nonlinear is a curved line and whose direction is constantly changing.
Hence, a nonlinear function is a function with a slope that is not constant. An example of a nonlinear function is a quadratic function or equation.

Ten field hockey teams are competing in a tournament. Only the top three teams will be recognized as the first place, second place and third place winners. In how many ways could the ranking of the top three teams occur?
Answer:
The ranking of the top three teams could occur in 720 ways.
Step-by-step explanation:
The order in which the teams are ranked is important, that is, for example, Oilers, Flames and Canucks is a different outcome of Oilers, Canucks and Flames. This means that the permutations formula is used to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]
In how many ways could the ranking of the top three teams occur?
Three teams from a set of 10. So
[tex]T = P_{(10,3)} = \frac{10!}{7!} = 720[/tex]
The ranking of the top three teams could occur in 720 ways.

Step-by-step explanation:
65÷b+8×4=20
Put the value of b=5 in equation
65÷5+8×4=20
According to BDMAS rule
13+32=20
45=20
Bring the terms on one side
45-20=25 Answer
Answer:
false
Step-by-step explanation:
use bidmas :)
ok, let's rewrite this for b = 5
65 ÷ 5 + 8 × 4 = 20
now put brackets
(65 ÷ 5) + (8 × 4) = 20
(13) + (32) = 20
13 + 32 = 45
45 ≠ 20
false

In the following diagram, a quarter circle has been constructed using an isosceles right triangle whose legs measure 8 inches. Which of the following represents the area of the shaded region, rounded to the nearest tenth of a square inch?
Answer:
Area of Shaded Area = 18.3
Step-by-step explanation:
P.S - The exact question is -
Given - In the following diagram, a quarter circle has been constructed using an isosceles right triangle whose legs measure 8 inches.
To find - Which of the following represents the area of the shaded region, rounded to the nearest tenth of a square inch?
Proof -
We know that,
Area of a quarter circle = [tex]\frac{1}{4} \pi r^{2}[/tex]
Also,
We know that ,
Area of isosceles Triangle = [tex]\frac{1}{2}*Base*Height[/tex]
Now,
Given that,
Radius of quarter circle = 8 inches
Base of Isosceles Triangle = 8 inches
Height of Isosceles Triangle = 8 inches
∴ we get
Area of a quarter circle = [tex]\frac{1}{4} \pi (8)^{2}[/tex] = 16[tex]\pi[/tex]
Area of isosceles Triangle = [tex]\frac{1}{2}*8*8[/tex] = 32
Now,
Area of Shaded area = Area of a quarter circle - Area of isosceles Triangle
= 16[tex]\pi[/tex] - 32
= 50.265 - 32
= 18.265 ≈ 18.3
⇒Area of Shaded Area = 18.3
