For starters, we need to calculate the original total price (the price he wouldve had to pay if there was no discount). If he bought 6 books, and every book costs $8, then he wouldve had to pay 6*8 dollars or 48 dollars.

Now, he got 20% off of the price, meaning they took 20% of the total price and subtracted that from the total price.

Lets calculate 20% (which can also be written as 20/100, or 2/10):

48 * (2/10)
48*2 / 10
96/10 = 9.6

This is what the cashier took off the total price.

48.00 - 9.60 = 38.40

So he spent $38.40 in total on books.

Which description of the graph of the linear inequality y ≥ 7x – 4 is correct? The graph will be a dashed line with a y-intercep
o-na [289]

Answer:

The correct option is B

B) The graph will be a solid line with a y-intercept of negative four and a slope of seven. The graph will be shaded above the line.

Step-by-step explanation:

The given equation is

y ≥ 7x - 4

Consider only the equality sign:

y = 7x-4

or

y = 7x + (-4)

The general form of any linear equation is given by:

y = mx + c

By comparing, we can see that:

m = slope = 7

Secondly consider the equation

y ≥ 7x - 4

We know that generally for the signs "equal to and greater/smaller than", we use a solid line, and for the signs "greater/smaller than", we use a dashed line.

Hence, to graph this equation we'll use a solid line.

Thirdly, find y intercept by putting x=0

y = 7(0) - 4

y = -4

The correct option is B

In the diagram, A||B and B||C. Find the values of X.
Airida [17]

Answer:

31

Step-by-step explanation:

3x + 12 and 105 are alternate exterior angles because A || B and B || C.

If the two or more lines are parallel, then the alternate exterior angles are equal.

3x + 12 = 105

Substract 12 on both sides,

3x = 105 - 12

3x = 93

Divide 3 on both sides,

x = 93 / 3

x = 31

A small plane is flying at 150 feet. It ascends to 325 feet. Write and solve an equation to find the change in altitude of the s
mel-nik [20]

Answer:

  175 ft

Step-by-step explanation:

Let c represent the change in altitude. Then an equation can be written:

  150 +c = 325

We solve for c by subtracting 150 from both sides of the equation:

  c = 325 -150 = 175

The change in altitude is an increase of 175 feet.

_____

This confirms the general rule that to find the value of a change, you subtract the original value from the new value. Here, that means ...

  c = 325 -150 = 175 . . . . as above.
