Answer:

a. 6.93 b. 5 c. 6.72 d. 3.46

Step-by-step explanation:

a.  √4^2- 4(4)(-2)

      Evaluate the power

    √16-4×4(-2)

      Multiply

    √16-16(-2) = √16-(-32) = √16+32 Since 2 negatives equal a positive.

      Add

    √48

      Find square root

     √48= 6.92820323028-- rounded-- 6.93

b.   √1^2-4(1)(-6)

      Evaluate the power

     √1-4(1)(-6)

       Multiply

      √1-(-24) = √1+24 Since 2 negatives equal a positive.

       Add

       √25

       Find the square root

       √25=5

c.     √1^2-4(1)(-11)

       Evaluate the power

       √1-4(1)(-11)

       Multiply

       √1-(-44) = √1+44 Since 2 negative equal a positive.

       Add

       √45

       Find the square root

       √45= 6.7082039325-- rounded-- 6.72

d.     √6^2-4(3)(2)

        Evaluate the power

        √36-4(3)(2)

        Multiply

        √36-24

        Subtract

        √12

        Find the square root

        √12= 3.46410161514-- rounded-- 3.46

Which system of inequalities is shown? A. Y&gt;x y&lt;2 b. Y 2 D. Y&gt;x y&gt;2
AURORKA [14]

Answer: y > x, y > 2

The horizontal line goes through 2 on the y axis. This boundary line is represented by the equation y = 2, since every point on this line has a y coord of 2. The shading above it means that the inequality is y > 2. Every point in the shaded region of y > 2 has a y coord that is larger than 2.

The other inequality is y > x because we shade above the dashed boundary line y = x, which is that slanted dashed line.

Combining the two regions of y > 2 and y > x leads to what is shown.

60 percent of a number, minus 17, is -65
Reika [66]

Answer:

We have (60/100)·x - 17 = - 65;

Then (6/10)·x = 17 - 65;

(3/5)·x = - 48;

x = (5/3)·(-48);

x = 5·(-16);

x = - 80;
