Answer: 7.5

Form your proportion. Let x be the width of QRST.

Length of ABCD      Length of QRST
-----------------------  =  ------------------------- 
Width of ABCD         Width of QRST

8/5 = 12/x

Solve for x by cross-multiplying.
(8)(x) = (12)(5)
8x = 60
x = 7.5

Pavlova-9 [17]

Answer:

C = $137.50

Step-by-step explanation:

Okie dokie, so we already know he charges $50 just for a service call, plus 25 per hour, so let's say the total charge is C.

Now, let's make an equation:

C = 50 + 25(3.5)

Now, multiply 25 and 3.5 together:

C = 50 + 87.5

Now we just combine the like terms:

C = $137.5

Hope this helps :)

The discriminant explains how many solutions the quadratic function has. It is found using this formula:

b^2-4ac

Using the formula, there are three rules. Let's say the discriminant=d:
d<0 - No solution ø
d=0 -ONLY 1 solution
d>0 -2 solutions

In the following graph, there are no solutions as the graph does not hit the x-axis at any point. Thereafter, the discriminant MUST be less than zero. Let's view the options check which one agrees with our answer.

A - Discriminant is greater than 0, which means two solutions. This is WRONG.
B - Discriminant is less than 0, which means no solutions. CORRECT!
C- Discriminant is equal to 0, which means one solution. WRONG!

Your answer is B.
