Write an equation of the line in slope-intercept form (–2, –2), slope = –4 * A) y=-4x +10
B) y=-4x-6
C) y=4x-10
D) y=-4x-10

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x

the answer is b.

surface area: 169π

volume: 366π

i got it down.

the angles measure to 70 degrees, 70 degrees, 20 degrees, and 20 degrees
