Answer:

x - 9 = 19 x = 28

8y -5x = 16 idk but what i do know is this...

Step-by-step explanation:

8 x 5 - 5 x 5 = 15 & 8 x 4 - 5 x 3 = 17

so if u want to try to put in some numbers u might find it.

but it would be better if i had answer choices.

Which equation describes a line that passes through (-6, 8) and is parallel to the line described by y = 2x − 4?

AleksandrR [38]

Answer:

hey, there!

Step-by-step explanation:

The given is a point (-6,8) through which a line passes. And is perpendicular to the line y = 2x-4

The equation for point (-6,8) is,

(y-8)= m1(x+6)...........(i)

and given equation is y = 2x-4............(ii)

Now, from equation (ii).

slope (m2)= 2 { as equation (ii) is in the form of y= mx+c where m is a slope}.

Now, For perpendicular,

m1×m2= -1

m1×2= -1

Therefore, m1 = -1/2.

Putting, the value of m1 in equation (i).

(y-8) = -1/2×(x+6)

2(y-8)= -1(x+6)

2y - 16 = -x -6

x+2y-10 = 0......... is the required equation.

Hope it helps...

At a zoo, the lion pen has a ring-shaped sidewalk around it. The outer edge of the sidewalk is a circle with a radius of 11 m. T

klio [65]

The formula for finding area of a circle is $\pi r^2$ .

Essentially, we have two circles here. One is a larger outer circle, and the other in a smaller inner circle. In order to find the area of the sidewalk, we must find the area of the outer circle, then find the are of the inner circle. After we find both areas, we subtract.

See attached image for process of finding area, and subtracting areas to find the final area of the sidewalk.
