What is the answer 5x² – 33x - 14 = 0​
KatRina [158]

Answer:

X=-2/5,7

Step-by-step explanation:

5x² – 33x - 14 = 0​

5x^2-(35-2)x-14=0

5x^2-35x+2x-14=0

5x(x-7)+2(x-7)=0

(5x+2)(x-7)=0

X=-2/5,7

so the value of X is -2/5,7

Solve the compound inequality 6b &lt; 42 or 4b + 12 &gt; 8.
sukhopar [10]

Step-by-step explanation:

6b < 42 or 4b + 12 > 8

6b < 42

= 6b/6 < 42/6

= b < 7

4b + 12 > 8

=4b - 12 + 12 < -12+8

= 4b > - 12 + 8

= 4b > -4

= 4b/4 = -4/4

b > -1

so

7 > b > -1

What is the slope of a line perpendicular to the line whose equation is 2x+2y=28
malfutka [58]

Answer:

1

Step-by-step explanation:

1) First, place the given equation in slope-intercept form (y = mx +b format) to find its slope easier. Isolate the y:

2x + 2y = 28\\2y = -2x + 28\\y = -x+14

So, the equation of the line in slope-intercept form is y = -x + 14. When an equation is in slope-intercept form, the m, or the coefficient of the x-term, represents the slope. Thus, the slope for the given line would be -1.

2) Lines that are perpendicular have slopes that are opposite reciprocals of each other. We need to find the opposite reciprocal of -1, then.

To find the opposite reciprocal of a number, write the given number as a fraction first -- making -1 be written as   -\frac{1}{1} -- then switch the sign and flip the numerator and denominator. So, the opposite reciprocal of -1 is 1, and 1 is the slope of the perpendicular line.
