Answer:

y < -2/3x +4

Step-by-step explanation:

The line intersects the y-axis at y=4, so that is the y-intercept.

The line drops 2 units for each 3 units to the right, so the slope is ...

(change in y)/(change in x) = -2/3

The slope-intercept form of the equation for a line is a form you have memorized:

y = mx + b . . . . . . for slope m and y-intercept b

Using the values we read from the graph, the equation of the line is ...

y = -2/3x + 4

The line is dashed, so the inequality does not include points on the line. The solution just includes y-values less than (below) those on the line. Hence the inequality is ...

y < (-2/3)x +4

Area of rectangle: b*h

12*5=60

10*5=50

(60*4)+(50*4)=440

The total surface area of the visible sides of the boxes would be 440 square inches.

Hope this helps!

Which three steps are correct when solving this quadratic equation by completing the square? X^2-10x=39

sergey [27]

Step-by-step explanation:

Any answer that involes,

Step 1: Complete the Square

${x}^{2} - 10x = 39$

$( \frac{ - 10}{2} ) {}^{2} = 25$

${x}^{2} - 10x + 25 = 64$

Step 2: Turn the left side into a binomial

$(x - 5) {}^{2} = 64$

Step 3: Solve for x.

$x - 5 = + - 8$

$x - 5 = 8$

$x = 13$

$x - 5 = - 8$

$x = - 3$

X=-3 or X=13
