Answer:

x=-7

Step-by-step explanation:

1. Distribute the 7 into the parenthesis: -7-2x=7x+56

2. Combine like terms by doing the opposite operation to the numbers: -7=9x+56 (added 2x to 7x)

3. Subtract 56 to each side of the equation: -63=9x

4. To isolate the variable "x," divide each side by 9: x=-7

When randomly choosing two cards from a standard deck of cards without replacement, what is the probability of choosing a face c

Radda [10]

There are 12 face cards and 4 aces to choose from. For the first card, the probability of drawing a face is $\dfrac{\binom{12}1}{\binom{52}1}=\dfrac{12}{52}$ . Then the probability of drawing an ace second is $\dfrac{\binom41}{\binom{51}1}=\dfrac4{51}$ .

So the probability of drawing these two particular cards in the given order is

$\dfrac{12}{52}\cdot\dfrac4{51}=\dfrac4{221}$

So since each car wash equals $7, you round 12 to 10 and $7 * 10 = $70.
Plus, 22 to 20.
So, $70 * 20 = $1400
So the answer is 1,400

How do you determine the degree of a polynomial

yawa3891 [41]

Answer:

The degree of a polynomial refers to the highest degree of its individual terms having non-zero coefficients.

Step-by-step explanation:

The degree of a polynomial refers to the highest degree of its individual terms having non-zero coefficients. For example;

A quadratic polynomial is a polynomial of degree 2. This polynomial takes the general form;

$ax^{2}+bx+c$

where a, b, and c are constants. This is usually referred to as a quadratic polynomial in x since x is the variable. The highest power of x in the polynomial is 2, hence the degree of any quadratic polynomial is 2.

A second example, consider the cubic polynomial;

$ax^{3}+bx^{2}+cx+d$

The degree of this polynomial is 3.
