6x - 2y = 12

Mathematics
1 answer:
ollegr [7]3 years ago
7 0

Step-by-step explanation:

Here given

6x - 2y = 12

2y = 6x - 12

2y = 6(x - 2)

y = <u>6</u><u>(</u><u> </u><u>x </u><u>-</u><u> </u><u>2</u><u>)</u>

2

y = 3(x - 2)

y = 3x - 6

Comparing with y = mx + c

so slope (m) = 3

Hope it will help you :))

3/4 (x - 3) - 5 = 1/8 ( x - 1 )
KonstantinChe [14]

Answer:

x = - \frac{57}{5}

Step-by-step explanation:

\frac{3}{4} (x - 3) - 5 = \frac{1}{8} (x - 1)

Multiply through by 8 to clear the fractions

6(x - 3) - 40 = x - 1 ← distribute parenthesis and simplify left side

6x - 18 - 40 = x - 1

6x - 58 = x - 1 ( subtract x from both sides )

5x - 58 = - 1 ( add 58 to both sides )

5x = - 57 ( divide both sides by 5 )

x = - \frac{57}{5}

Help due in 45 minutes!!
Nat2105 [25]

Answer:

(14,-1)

Step-by-step explanation:

okay so first you need to use the "x=4y+10" in the first equation.

Rewrite as

3(4y+10) +11y=7

Distribute the 3(4y+10)

Rewrite as

12y+30

You'll have the equation

12y +30 +11y= 7

Subtract the 7 from both sides

12y+30+11y-7= 0

Combine like terms

23y+23=0

the best thing to do here is divide the equation by 23.

23/23 = 1

you'll have

y + 1 = 0

this simplifies to

y= -1

use this y value to solve for x

the easiest way to do this is start with the equation

x = 4y +10

Substitute the y for -1

x = -4(-1) +10

x = 4 +10

x = 14

the solution point is

(14,-1)

Find the lateral surface area of a
balandron [24]

Answer:

15.1 mm²

Step-by-step explanation:

Lateral surface area of a cylinder = 2πrh

(where r is the radius and h is the height)

Given:

  • r = 1.2 mm
  • h = 2 mm

Substitute given values into the formula:

⇒ Lateral surface area = 2π(1.2)(2)

                                      = 4.8π

                                      = 15.1 mm²  (nearest tenth)
