Answer:
2x - 7y = -34.
Step-by-step explanation:
As the line we want is perpendicular to y= -7/2 x + 9 it's slope will be
-1 /(-7/2) = 2/7.
Now we find the point of intersection ofn the 2 given lines:
x + y = 10
3x - 4y = -12
Multiply the first equation by -3:
-3x - 3y = -30
Now add this last equation to the second one:
-7y = -42
y = 6
Plug y = 6 into the first equation:
x + 6 = 10
x = 4.
So the point of intersection is (4, 6) and the equation we want passes through this, so using the point-slope form of straight line we have:
y - 6 = 2/7(x - 4)
7y - 42 = 2(x - 4)
7y - 42 = 2x - 8
2x - 7y = -42 + 8
2x - 7y = -34
Answer:
y=(2/7)x+(7/3)
Step-by-step explanation:
y=-7/2(x)+9
y=mx+c
Therefore, slope of line y is -7/2
Because line y perpendicular to the required line
Therefore, slope of the required line is 2/7
x+y=10 ........(1)
3x-4y = -12 ......(2)
(1) x 4:
4x+4y =40 ......(3)
(3) + (2)
4x+4y+3x-4y=28
x=4
by substituting x=4 into (1), we have
y=10-4=6
Therefore, the point that the line intersects is (4, 6)
let y=(2/7)x+c be the required equation
(4, 6):
6=(2/7)4+c
c=21/4
therefore, the required equation is y=(2/7)x+(7/3).

The area of a circle is 121π ft². What is the circumference, in feet?
Answers
Answer:
· Area = pi*r^2. 121 = pi*r^2. Solve for r. Circumference = 2*pi*r. plug r into that equation and solve for Circumference
Use the given functions to set up and simplify f e e t . 121 π f t 2 = f e e t = f e 2 t
Step-by-step explanation:
The circumference of the given circle will be 22π feet.
What is circumference?Circumference refers to the distance around the edge of a circle or any other curved shape. It is essentially the perimeter of the circle, and it is calculated by multiplying the diameter of the circle by the mathematical constant pi (π).
The area of a circle is given by the formula:
A = πr²
where "r" is the radius of the circle. We are given that the area of the circle is 121π ft². Therefore, we can write:
121π = πr²
Dividing both sides of the equation by π, we get:
121 = r²
Taking the square root of both sides of the equation, we get:
r = 11
Therefore, the radius of the circle is 11 feet.
The circumference of a circle is given by the formula:
C = 2πr
Substituting the value of "r" that we found above, we get:
C = 2π(11) = 22π
The circumference is 22π feet.

y = 100,000[0.85]ˣ
Where x = Number of year
Find:
Number of year, when final value is $61,412.50
Number of year, when final value is $20,000
Computation:
Depreciation model
y = 100,000[0.85]ˣ
61,412.50 = 100,000[0.85]ˣ
0.614125 = [0.85]ˣ
x = 3
Number of year, when final value is $61,412.50 = 3 year
Depreciation model
y = 100,000[0.85]ˣ
20,000 = 100,000[0.85]ˣ
0.2 = [0.85]ˣ
x = 10 (Approx.)

The nose of the origami dog is a right angle with sides that are 2 cm, 3 cm, and 3.6 cm long. What is the area of this triangle?
Answers
Given:
The sides of a right triangle are 2 cm, 3 cm, and 3.6 cm.
To find:
The area of the right triangle.
Solution:
Area of a triangle is:
[tex]Area=\dfrac{1}{2}\times base\times height[/tex]
In the given triangle 3.6 cm is the largest side, it means 3.6 cm is the length of the hypotenuse. So, 2 cm and 3 cm and the base and height of the triangle.
Now, the area of the given triangle is:
[tex]Area=\dfrac{1}{2}\times 2\times 3[/tex]
[tex]Area=3[/tex]
Therefore, the area of the given triangle is 3 square cm.

The measure of the third side of the triangle will fall between 5 and 29.
What is the Triangle Inequality Theorem?Triangle Inequality Theorem is that for two sides of a triangle, the third side cannot be equal to or greater than the third side's length.
From the Triangle Inequality Theorem,
The sum of the lengths of any two sides of a triangle must be greater than the third side, then the third side of this triangle must be strictly less than 29.
But we can't make the length of the third side too small, either.
If x is the length of the third side, then x + 12 > 17, which means that x > 5
Therefore, the length of the third side must fall between 5 and 29.
Hence, the measure of the third side of the triangle will fall between 5 and 29.
