Which linear function represents the table?
A) y=7x-7
B) y=7x+7
C) y=-7x+7
D) y=-7x-7
Urgent!!! What is the solution of the system?
Answer:
(-38,18)
Step-by-step explanation:
Step: Solvex+3y=16for x:
x+3y+−3y=16+−3y(Add -3y to both sides)
x=−3y+16
Step: Substitute−3y+16forxin2x+5y=14:
2x+5y=14
2(−3y+16)+5y=14
−y+32=14(Simplify both sides of the equation)
−y+32+−32=14+−32(Add -32 to both sides)
−y=−18 Divide both sides by -1
[tex]\frac{-y}{-1} =\frac{-18}{-1}[/tex]
y=18
Step: Substitute18foryinx=−3y+16:
x=−3y+16
x=(−3)(18)+16
x=−38

The table shows the number of diagonals that can be drawn from one vertex in polygon. Write an equation in function notation for the relation and find the number of diagonals that can be drawn from vertex in a 12-sided polygon.
Answer:
y = x - 3; 9 diagonals
Step-by-step explanation:
Find the equation: y = x - 3
Plug in 12: y = 12 -3
Solve: y = 9
9 diagonals

What is Equation of line?
The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Table is shown in figure.
Two points on the table are (3, 0) and (4, 1).
Now,
Since, The equation of function passes through the points,
(3, 0) and (4, 1).
So, We need to find the slope of the function.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (1 - 0) / (4 - 3)
m = 1
Thus, The equation of function with slope 1 is,
⇒ y - 0 = 1 (x - 3)
⇒ y = x - 3
⇒ y = x - 3
Thus, The equation of function notation for the relation will be,
⇒ y = x - 3

18. A storage facility has small units designed to hold 40 - 50 large boxes, a large box on average weighs 85 lbs. On average, if someone fills the container to capacity, how much will all the boxes they store weigh?
a. 3400 lbs
b. 4250 lbs
c. 4175 lbs
d. 3825 lbs
Answer:
All the boxes in the store will weigh b. 4,250 lbs.
Step-by-step explanation:
Well, we know that the storage facility can hold a maximum of 50 large boxes, each weighing about 85 pounds.
85 x 50 = 4,250
Therefore, all the boxes in the store will weigh b. 4,250 lbs.

The diameter of the solar system is about 300,000,000,000,000 kilometers,
which can be written as 3 x 100 kilometers. What is n?
Answer:
D. 14.
Step-by-step explanation:
As we know, 10 to the second power is 100, to the third power is 1000, and so on. These powers add a zero to the number. Since PEMDAS tells us to do exponents before multiplication, we need to find what power of 10 gives us 100,000,000,000,000. Let's count all the zeros. There are 14 zeroes. This means our answer is D. 14. Let's check, though. 10 to the 14th power is 100,000,000,000,000, and that times 3 is 300,000,000,000,000. That means our answer is correct, it is in fact, D. I hope this helps!
Edit: I changed the answer from 13 to 14 because I realized that 13 is incorrect.

Algebra I
Combining Like TermsStep-by-step explanation:
Step 1: Define Equation
2(x + 2x) = 36
Step 2: Solve for x
Combine like terms: 2(3x) = 36Divide both sides by 2: 3x = 18Divide both sides by 3: x = 6Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 2(6 + 2(6)) = 36Multiply: 2(6 + 12) = 36Add: 2(18) = 36Multiply: 36 = 36Here we see that 36 does indeed equal 36.
∴ x = 6 is the solution to the equation.
Answer :
2(x+2x)=36
2x + 4x =36
6x =36 is the answer

the angle of a elevation of the top of a tree from an observer standing 10m away from the foot of the tree is 56°. Calculate the height of the tree.
Explain your answer pls,thx
Answer:
14.83 meters
Step-by-step explanation:
Given that :
Angle of elevation (α) = 56°
Distance between observer and foot of tree = 10 meter.
Height of tree =?
Using trigonometry :
The height (h) of the tree can be obtained using :
Tan α = opposite / Adjacent
Tan(56°) = h / 10
1.4825609 = h / 10
Multiply both sides by 10
1.4825609 * 10 = h
14.8256 = h
Hence, the height of the tree is 14.83 m(2 decimal places).

.
The cross-sectional area of the shaft is 314 mm²
The outside diameter (d₂) = 6 cm = 60 mm
The inside diameter (d₁) = 4 cm = 40 mm
The cross sectional area of the shaft (A) is given by:
A = π(d₂ - d₁)²/4
Substituting values:
A = π(60 - 40)²/4
Simplifying the equation:
A = 314 mm²
The cross-sectional area of the shaft is 314 mm²
