Answer:

c = - 7

Step-by-step explanation:

the standard form of a quadratic equation is

ax² + bx + c = 0 : a ≠ 0

x² + 4x - 7 = 0 is in standard form

By comparison of the coefficients of the terms, c = - 7

Nicole has 17 nickels n and dimes d. If the value of her coins is $1.30, how many of each coin does she have?
denis-greek [22]

Answer:

  8 nickels and 9 dimes

Step-by-step explanation:

If all were dimes, the value would be $1.70. It is $0.40 less than that. Changing a dime for a nickel reduces the value by $0.05, so there must have been $0.40/$0.05 = 8 such changes.

There are 8 nickels and 9 dimes.

_____

<em>Check</em>

8 · 0.05 + 9 · 0.10 = 0.40 + 0.90 = 1.30 . . . the answer checks OK

HELP PLEASE!!!!!!! Asap Giving out brainliest!<br> Which of the following has the greatest value?
Jlenok [28]
1/3^-2

You flip the denominator and the numerator to make the 3^-2 positive. 

3^2/1= 3^2= 9 

1/2^-3 

2^3/1= 2^3= 8 

I can already tell you that the negative exponents are not going to be as high in value. 

3^-2= 1/3^2= 1/9
2^-3= 1/2^3= 1/8

1/3^-2 (the first option) <=== the highest in value

I hope this helps!
