Answer to this math question.?
(3x + 6y = 48) x -1 -5x + 6y = 32 -3x -6x = -48 -5x + 6y = 32 -8x = -16 x = 2 -5x + 6y = 32 -5(2) + 6y = 32 -10 + 6y = 32 6y= 42 y=7 x=2 y=7

Let OD= R and OH=R/2IH=IC=rwe have OI ^2=OH^2+IH^2 => OI=sqrt(R^2/4+r^2)IC=R-OI=R-sqrt(R^2/4+r^2)= rsolve this equation we will get r= 3/8.R or r/R=3/8

The width of the path = the diameter of the blade (or the circle it sweeps through) = 20 in So 1 revolution = (20 pi) in Angular speed of blade = 2,800 rev/min So, linear speed of blade tip = (2,800 x 20 pi) in/min = 56,000 pi in/min = (56,000 pi in/min 60 min/hr)/(63,360 in/mile) = (56,000 pi x 60/63,360) miles/hr = approx. 166.6 miles/hr Note: Velocity is a vector quantity so it requires a direction as well as a magnitude. Also, the speed of the blade tip will vary. It will be a little more than 166.6 miles/hr when it is moving in the same direction as the mower and a little less when moving in the opposite direction.

1 nm = 10^(-9) m Multiplying both sides by 0.15 gives : 0.15 nm = 0.15 * 10^(-9) m To put into standard form, multiply 0.15 by 10 and divide 10^(-9) by 10 : = 1.5 * 10^(-10) m

2y+6x=3 subtract 6x from both sides 2y= -6x+3 divide both sides by 2 y = -3x + 1.5 this represents a linear equation because it is based on the equation: y=mx+b in y = mx+ b, y equals the y coordinate of a graph, m represents the slope, x represents the x coordinate, and b represents the y-intercept. because the slope is -3, the line will slope downward. remember, slope is rise over run, meaning that the top number is the number up or down, and the bottom number is the number to the left or right. -3 = -3/1, meaning that, in this case, your line will go down 3 units and to the right 1 unit.
