X = 1 - y & 3x = 8 - 5y ; Find x
Plug in x into the second equation.
3x = 8 - 5y
3(1 - y) = 8 - 5y
Simplify.
3 - 3y = 8 - 5y
Add 5y to both sides.
3 - 3y + 5y = 8
Subtract 3 from both sides.
-3y + 5y = 8 - 3
Simplify.
2y = 5
Divide both sides by 2.
y = 5/2
Now, since you have the value of y, you simply plug y into the first equation.
x = 1 - y
x = 1 - 5/2
Simplify.
x = 1 - 2 1/2
Simplify.
x = -2/2 - 5/2
Simplify.
x = -7/2 AND -3 1/2

Answer:
sure
Step-by-step explanation:
best of luck
since the polygon has 8 chambers the angle of one chamber = 360/8 = 45°
so the angle WOP = 45°
now drawing a imaginary line which seperates the triangleWOP into half
so the angle of imaginary line is 45/2 = 22.5
sin(theta) = opp/hyp
since WP (opp) is unknown. take as x
sin(22.5) = x/44
0.383×4 = x
x = 1.532 (app) = 1.5 cm
perimeter = 1.5 × 8
= 12 cm
area of triangle WOP = 2×1/2 ×bh = bh
= 4×1.5
= 6 cm²
so the area of regular polygon = 8× area of a triangle
= 48 cm²
Answer:
A. 4
Step-by-step explanation:
Constant of proportionality (k) = y/x
We can use the coordinates of any point on the line to find k.
Let's use (2, 8)
Constant of proportionality (k) = 8/2
Constant of proportionality (k) = 4
