Answer:
10 sq. ft.
Step-by-step explanation:
2×5=10
-inch blades (so the radius of the circular fan is
20
inches). Suppose the linear speed of the tip of a blade is
10
feet per second.
Hi,
2x - 45 = - 3x
2x + 3x = 45
x = 45/5 = 9.
Answer:
x=9
Step-by-step explanation:
2x-45=7x-9x-x
2x-45= -3x
5x=45
x=9
The slope-intercept form of the given line, expressed in point-slope form as y - 4 = (x - 8), is y = x - 4. This indicates a slope of 1 and a y-intercept of -4.
The point-slope form of the equation of the line, y – 4 = (x – 8), illustrates a line passing through the point (8, 4) with a specific slope. The slope is the difference in the y-coordinates divided by the difference in the x-coordinates, as illustrated in the given figures.
In general, the equation of a straight line in slope-intercept form is given by y = mx + b, where m is the slope of the line and b is the y-intercept, i.e., the value of y when x is zero.
To convert the original equation into slope-intercept form, rearrange it by solving for y. First, rewrite the equation as y - 4 = x - 8, then add 4 to each side to isolate y:
y = x - 8 + 4
y = x - 4
So, the slope-intercept form of the equation for this line is y = x - 4, implying the line has a slope (m) of 1 and a y-intercept (b) of -4.
