What is the solution of the inequality 7(x + 4) < 2(x–5) + 3(x + 9)?
emmasim [6.3K]

Answer:

x< -8.125

Step-by-step explanation:

7(x+4) < 2(x-5) -3(x+9)

distribute 7, 2, -3 to the parentheses to the right

7x+28<2x-10-3x-27

add like terms

7x+28<x-37

add x to 7x and subtract -28 to -37

8x<-65

divide both sides by 8

x<-8.125 or (-65/8)

PLEASE HELP!! please do all steps! i’ll mark as brainliest!!!
aalyn [17]

Answer:

-3x⁴ - 9x³ + 15x² = -3x² (x² + 3x -5)

10x³ -35x² + 6x - 21 = (2x - 7) (5x² + 3)

Step-by-step explanation:

-3x⁴ - 9x³ + 15x² = -3x² (x² + 3x -5)

10x³ -35x² + 6x - 21 = (2x - 7) (5x² + 3)

c = the number of Nora's coworkers who attend the picnic v = the number of veggie burgers Nora prepares Which of the variables i
AveGali [126]

Answer: Independent variable = c

Dependent variable = v

Step-by-step explanation:

  • The independent variable does not depend on any other variable.
  • Dependent variable dependent on another variable.

Given variables:

c = the number of Nora's coworkers who attend the picnic

v = the number of veggie burgers

Here the number of burgers required is dependent on the number of Nora's coworkers who attend the picnic.

Therfeore, Independent variable = c

Dependent variable = v

The equation for line g is given by 5y=2x-20. Suppose line g is parallel to like r and line e is perpendicular to line g. Point
VladimirAG [237]
Sounds as tho' all three lines are parallel.  Is that correct?

If so, all three lines have the same slope!

What is the slope of   <span>5y=2x-20  ?     Solving for y, y = (2/5)x - 4
</span>
The slope is (2/5).

Now find the equation of the line with slope (2/5) that passes thru (10,-8).

It is    y - [-8] = (2/5)(x - 10).

We can simplify this, with the result   y + 8 = (2/5)x - 4.  This, in turn, can be simplified to y + 8 = 2x/5 - 4,                  or   y = 2x/5 - 12.  Mult. all terms by 5 to eliminate the fraction:


5y = 2x - 60

Note how this has the exact same form as the given  5y = 2x - 20, EXCEPT that the constant at the end is different.

5y = 2x - 60    and    5y = 2x - 20 are parallel lines with the same slope but different y-intercepts.
