Find the length of CD A. 6 meters B. 7 meters C. 8 meters D. 9 meters

Mathematics
1 answer:
shutvik [7]3 years ago
6 0

Answer:

D. 9 meters

Step-by-step explanation:

AB = CD, so 9x-27=2x+1.

If you get like terms on the same side you get 7x=28

If you simplify by dividing everything by 7, you get x=4

If you plug 4 in as x into the expression 2x+1, you get 9.

the point slope form of the equation of a line that passes through (8,4) and (0,2) is y-4=1/4(×-8) what is the slope intercept f
marissa [1.9K]

Answer:

\large\boxed{y=\dfrac{1}{4}x+2}

Step-by-step explanation:

The slope-intercept form of the equation of a line:

y=mx+b

m - slope

b - y-intercept → (0, b)

The point-slope form of the equation of a line:

y-y_1=m(x-x_1)

m - slope

(x₁, y₁) - point

We have the equation of a line:

y-4=\dfrac{1}{4}(x-8)\to m=\dfrac{1}{4}

and the point (0, 2) → b = 2.

Substitute:

y=\dfrac{1}{4}x+2

Savatey [412]
6 \frac{1}{8}-1 \frac{11}{12}=    \frac{49}{8}- \frac{23}{12}=  \frac{49*3-23*2}{24} =  \frac{147-46}{24}=  \frac{101}{24}=4 \frac{5}{24}
