Answer:
y = 25x
Step-by-step explanation:
slope is 25 because to move from one point to another (on the line) you move up 50 (from 0 to 50) and to the right 2 (from 0 to 2) slope is 50/2 which simplified to 25
when x = 0, y = 0 so the y intercept is 0 but it isn’t necessary to add it to the equation
Answer:
x = 9
Step-by-step explanation:
2x - 3 = 15
2x = 15 + 3
2x = 18 (divide both sides by 2 to get x)
2x/2 = 18/2
x = 9
Answer:
(0,-3)
Step-by-step explanation:
2x-y = 3
x+2y = -6
Multiply the first equation by 2 so we can eliminate y
2(2x-y =3)
4x -2y = 6
Add this to the second equation
4x -2y = 6
x+2y = -6
-----------------
5x +0y = 0
x = 0
Now find t
x+2y = -6
0+2y = -6
2y =-6
Divide by 2
y = -3
Answer:
51.9 cm²
Step-by-step explanation:
From the diagram attached,
Area of the white region(segment)(A) = Area minor sector- area of the triangle
A = (πr²∅/360°)-(1/2r²sin∅)............... Equation 1
Where r = radius of the circle, Ф = reflex angle formed at the center of the circle, π = pie
From the question,
Given: r = 7 cm, Ф = 150°
Constant: π = 22/7
Substitute these values into equation 1
A = [(22/7)×7²×150/360]-[(1/2)×7²×sin150]
A = 64.17-12.25
A = 51.92
A = 51.9 cm²
