kap26 [50]

Answer:

1. 16 cups

2. 8 pints

Step-by-step explanation:

In this question, we are asked to calculate the amount of cups of juice made from a certain gallon and the amount left in pints after some certain amount of the juice was consumed.

To solve this problem, we need to know the amount of cups present in a gallon of juice.

Mathematically, there are 16 cups present in a gallon. Now since she made two gallons, the amount of cups present is thus 16 * 2 = 32 cups of juice

2. 16 cups was consumed by the family. The amount of cups left is thus 32 - 16 = 16 cups of juice

We need our answer in pints however.

Mathematically, 1 pint is composed of 2 cups.

This means 16 cups would be composed of 16/2 pints = 8 pints

What are the values of the coefficients and constant term of 0 = 4 – 7x2 + x in standard form?

katen-ka-za [31]

ANSWER

$a = - 7$

$b = 1$

$c = 4$

EXPLANATION

The given quadratic equation is:

$0 = 4 - 7 {x}^{2} + x$

We rewrite in the standard quadratic equation form to obtain,

$- 7 {x}^{2} + x + 4 = 0$

Comparing this to the general standard quadratic equation.

$a {x}^{2} + bx + c = 0$

We have my

$a = - 7$

$b = 1$

$c = 4$
