Answer= y = 9
Simplify both sides of the equation
4y-40=-4
add 40 to both sides
4y - 40 + 40=-4 + 40
4y= 36
divide both sides by 4
4y/4 = 36/4
36/4 = y=9
Answer:
height = 5.682 meters
Step-by-step explanation:
height = -9.8x^2 + 7x + 3
Find the axis of symmetry: x = -b/(2a)
a = -9.8 b = 7 c = 3
x = -7/(2*-9.8) = -7/-19.6 = .357 = x = +.357 secs is when max height occurs
Find the height, replace x with .561
height = -9.8(.357^2) + 11(.357) + 3
height = -9.8(.127) + 11(.357) + 3
height = -1.245+3.927+3
height = 5.682

Answer: (-4/3, 2)
Let x = the length of each side of the square.
Therefore the dimensions of the rectangle are x and x/2.
Because the perimeter of the rectangle is 15 inches, therefore
2x + 2(x/2) = 15
2x + x = 15
3x = 15
x = 5 in.
The perimeter of the square scarf is 4x = 4*3 = 12 in.
The area of the scarf is 3*3 = 9 in²
Answer:
Perimeter = 12 in
Area = 9 in²
