3х + 4 = 2х +6 What is the answer

Mathematics
1 answer:
AnnyKZ [126]3 years ago
8 0

Answer:

x=2

Step-by-step explanation:

First step is to move the variable to one side. To do this, subtract 2x to both sides since it's the smaller amount.

3x+4= 2x+6

-2x      -2x

Then, subtract 4 to both sides.

x+4= 6

 -4   -4

This will leave you with the answer of x=2.

Write an equation of the line in slope-intercept form: y-intercept of 2, x-intercept of 4
zvonat [6]

Answer:

\sf y=-\dfrac12x+2

Step-by-step explanation:

y-intercept is when x = 0, so (0, 2)

x-intercept is when y = 0, so (4, 0)

\sf slope=\dfrac{change\:in\:y}{change\:in\:x}=\dfrac{0-2}{4-0}=-\dfrac12

Slope-intercept form of linear equation:  \sf y=mx+b

(where m is the slope and b is the y-intercept)

Given:

  • \sf m=-\dfrac12
  • b = 2

\sf \implies y=-\dfrac12x+2

Determine which of the lines if any are parallel or perpendicular?
Tcecarenko [31]

Answer:

y=6x-2 is perpendicular to the 6y=-x+7

y=6x+1 is parallel to the y=6x-2

Step-by-step explanation:

if product of two lines gradient is -1 than lines are perpendicular

gr y=6x-2

    y=mx+c m=gradient

1)m=6

2)m=-1/6

3)m=6

if gradients of 2 lines are equal they are paralel

find the smallest number by which 339 must be multiplied so that the product is a perfect cube. also find the cube root of the p
Murljashka [212]

Answer:

<em>The smallest number is 114921 and the cube root of the result is 339</em>

Step-by-step explanation:

The number 339 can be factored as:

339 = 3 * 113

Both factors are prime, thus to produce a perfect cube, we must multiply by each factor to the power of 2, that is:

3^2*113^2=114921

When we multiply 339 by 114921 we get 38958219, a perfect cube which cube root is 339.

Thus, the smallest number is 114921 and the cube root of the result is 339
