Perform indicated multiplication on left side..

4-x+2=2x-12+3x  combine like terms on both sides

-x+6=5x-12  subtract 5x from both sides

-6x+6=-12  subtract 6 from both sides

-6x=-18  divide both sides by -6

x=3

Which gives 28 + 24 as a product of the GCF and a sum?
VashaNatasha [74]

Answer:

b. 4 (7 + 6)

Step-by-step explanation:

Finding the GCF between 28 and 24:

We keep dividing while both numbers can be divided by the same factor. So

28 - 24|2

14 - 12|2

7 - 6

There is no number for which 7 and 6 are both divisible by, so the GCF between 28 and 24 is 4.

Simplifying in function of the GCF:

Now, we put 4 in evidence, and divide the rest of the expression by 4. So

28 + 24 = 4(\frac{28}{4} + \frac{24}{4}) = 4(7 + 6)

The answer is given by option b.

What is the slope-intercept form of the equation of the line perpendicular to y = -x + 10 and passing throught the point (-2,7)?
notka56 [123]

Answer:

The slope-intercept form equation of the line perpendicular to y =  -\frac{1}{2} x + 10 and passes through point (-2, 7) is y = 2x + 11 ⇒ Not in the choices

Step-by-step explanation:

The slope-intercept form of the linear equation is y = m x + b, where

  • m is the slope
  • b is the y-intercept

The product of the slopes of the perpendicular lines is -1, if the slope of one is m, then the slope of the other is -\frac{1}{m}

  • To find the slope of the perpendicular line to a given line reciprocal the slope of the given line and change its sign

∵ The equation of the given line is y = -\frac{1}{2} x + 10

→ Compare it with the form of the equation above

∴ m =  -\frac{1}{2}

→ Reciprocal it and change its sign to get the slope of the ⊥ line

∴ m⊥ = 2

→ Substitute in the form of the equation above

∴ y = 2x + b

→ To find b substitute x and y in the equation by the coordinates of

   a point on the line

∵ The line passes through the point (-2, 7)

∴ x = -2 and y = 7

∵ 7 = 2(-2) + b

∴ 7 = -4 + b

→ Add 4 to both sides to find b

∵ 7 + 4 = -4 + 4 + b

∴ 11 = b

→ Substitute it in the equation

∴ y = 2x + 11

The slope-intercept form equation of the line perpendicular to y =  -\frac{1}{2} x + 10 and passes through point (-2, 7) is y = 2x + 11

<u><em>Note:</em></u> The answer is not in the choices
