HELP<br> what is the value of “ c”
Alex

Answer:

7

Step-by-step explanation:

When you match the form

... ax² + bx + c = 0

to the equation

... 3x² + 5x + 7 = 0

it is reasonable to conclude that ...

... a = 3, b = 5, c = 7.

_____

The question presumes you are familiar with the form

... ax² +bx +c = 0

which is often used as the representation of a general quadratic equation. This lets us use a, b, and c instead of specific numbers, to talk about ways of factoring, graphing, or solving equations like this.

d. If you double a certain number and subtrack 7 you get the same answer as when you add 5 to the number, Determine the number​
umka21 [38]

Answer:

12

Step-by-step explanation:

Let n = the number.

2n - 7 = n + 5

n = 12


Let’s check if we got the right answer by substituting 12 for n into the original equation.

2*12 - 7 = 12 + 5

24 - 7 = 17

17 = 17

If an items costs $41.04, including an 8% sales tax, what was the cost of<br> the item before taxes?
tankabanditka [31]

Answer:

$38

Step-by-step explanation:

I solved this by doing a proportion, 41.04/108 = x/100 to find the original price before the 8% tax. To solve this proportion you have to isolate the variable, so you would do the cross product and multiply (41.04 x 100) and have that equal to 108x. So then because you have 108x = 4104, isolate x by dividing by 108 and you get 38, thus $38.

You can also check your work by multiplying 38 by 0.08 to find the amount of sales tax added, and if you do this you will get the value $41.04.
