Jessica has $50 to spend on new clothes. The jacket that she wants to buy is $48.20. If the tax rate is 6% does Jessica have eno

Virty [35]

Answer:

Step-by-step explanation:

She has 50$. A jacket is on for 48.20$. The tax is 6% of the product you buy.

6% = 0.06

To find 6% you do:

0.06*48.20

Which is 2.892.

You ADD 2.892 to the price.

48.20+2.892=

51.092. Round it:

51.09 > 50.00

No, she does not have enough.

How many intersections are there of the graphs of the equations below?

kipiarov [429]

Answer:

The number of intersections = ∞

Step-by-step explanation:

Given the system of equations:

0.5 x + 5y = 6

3x + 30y = 36

By multiplying the first equation by 6

∴ 6 (0.5 x + 5y) = 6 * 6

∴ 3x + 30y = 36

So, Those equations are "Dependent", because they are really the same equation, just multiplied the first equation by 6.

So, the two equations are identical

Therefore: They have infinity number of solutions.

See the attached figure.

0.5 x + 5y = 6 ⇒ in black color

3x + 30y = 36 ⇒ in red color
