Answer:

28.87 inch

Step-by-step explanation:

The perimeter of a figure is the sum of the length of the boundary sides of the figure surrounding it.

For the above figure the perimeter is the sum of the three sides of the rectangle and circumference of the semicircle.

Diameter of the semicircle forming in the figure is 5 inch(given)

Circumference of the semicircle forming in the figure = $\pi r$

$3.14*2.5= 7.85 inch$ : $\pi =22/7=3.14$

The perimeter of the above given figure = $5 inch+7inch+7inch+7.85 =26.87 inch$

A line passes through the points (7, 3) and (8, 3). What is its equation in slope-intercept form?

Sati [7]

Answer:

y=3

Step-by-step explanation:

The y values are the same, so there cannot be a slope. The (mx) part of y=mx+b is cancelled out, and is left with the b. Since the y value is forever three, the y-intercept will be 3 as well.

Therefore, the slope-intercept equation is

y=3

What is the general form of the equation of the line shown?

Artyom0805 [142]

Answer:

Option A is correct.

General form of the equation of the line: y-2 = 0

Step-by-step explanation:

The general form of the equation is given by:

y = mx +b where m is the slope and b is the y-intercept.

y-intercepts of the line is the value of y at the point where the line crosses the y-axis(i.e x= 0)

From the given figure;

we can see that the line crosses the y-axis at y =2 and also here the slope is , m= 0

therefore, by definition of y-intercepts

y-intercept (b) = 2

Therefore, the equation of line as shoen in figure is:

y = (0)x + 2

y = 2

y-2 = 0

Therefore, the general form of the equation line as shown in the figure is:

y-2 =0

Answer:

D) x² -x - 10 =0

Step-by-step explanation:

Given that

$\frac{2}{3x-6} - \frac{1}{3x+6} = \frac{1}{3}$

L.C.M

$\frac{2(3x+6)-(3x-6)}{(3x+6)(3x-6)} = \frac{1}{3}$

$\frac{(6x+12-3x+6)}{(3x+6)(3x-6)} = \frac{1}{3}$

$\frac{(3x+18)}{((3x)^{2} )-(6)^{2} } = \frac{1}{3}$

⇒ $3(3x+18) = 9 x^{2} - 36$

⇒ 9 x + 54 = 9 x² - 36

⇒ 9 x² - 36 - 9x - 54 =0

⇒ 9 x² - 9x - 90 =0

⇒ 9(x² -x - 10 ) =0

⇒ x² -x - 10 =0
