2x - 1 = 5x + 5

-2x -2x

- 1 = 3x + 5

-5 -5

Write an equation in slope-intercept form: (1,6) and (2,3) are on the line

Answers

Step-by-step explanation:

eqn of line : y = mx+ c

m = slope or gradient

c = y-intercept.

Lets take (1,6) = (x1,y1) and (2,3) = (x2,y2)

[tex]m \: = \frac{y1 - y2}{x1 - x2} \\ = \frac{6 - 3}{1 - 2} \\ = \frac{3}{ - 1} \\ = - 3[/tex]

Substitute x = 1 and y = 6 into equation,

[tex]6 = ( - 3)(1) + c \\ 6 = - 3 + c \\ c = 6 + 3 \\ = 9[/tex]

Therefore substituting m and c value, equation of line is

[tex]y = - 3x + 9[/tex]

A shipping crate is 9 feet long, 4 feet wide, and 6 feet tall. What is the total surface area of the crate in square feet?

Answers

Answer:

Step-by-step explanation:

sureface area of rectanglur object is the sum of the six sides

Area = Length x Width

SArea = Top Area + Bottom Area + Front Area + Back Area + Left Side Area

+ Right Side Area

since the top and bottom have equal area = long x wide

the front and back have equal area = long x tall

and both sides have equal area = wide x tall

I summed the bottom front and side areas each times 2

SArea = 2(Bottom Area) + 2(Front Area) + 2(Side Area)

factor out the 2 and added the area formulas for the bottom front

and side

= 2 [ (long x wide) + (long x tall) + (wide x tall)]

= 2 [ (9 x 4) + (9 x 6) + (4 x 6)]

= 2 [ (9)(4) + (9)(6) + (4)(6)]

= 2( 36 + 54 + 24 )

= 2( 114)

= ???? What is 2 times 114 ???? You can finish this part.

Which function represents this sequence?

A.
f(n) = 4 ∙ 2n-1

B.
f(n) = 4n-1

C.
f(n) = 2 ∙ 4n-1

D.
f(n) = 2n-1

Answers

Answer: A. f(n) = 4 ∙ 2n-1

Step-by-step explanation:

because the 1st term is 4 according to your image, and then you will have to multiply that by its common difference and using your table, to get from 4 to 8 then 8 to 16 you would multiply by 2, and you would finally multiply that by n or known as the number of terms and 1 making the equation. f(n) = 4 ∙ 2n-1 I hope this is very helpful for everyone.
