Explanation

To solve the equation$2x+7=-9x-4$, follow these steps:

Step 1: Simplify and bring like terms together

$$2x+7=-9x-4$$

Add $9x$ to both sides:

$$2x + 9x + 7 = -4$$$$11x + 7 = -4$$

Step 2: Subtract 7 from both sides

11x=−4−7
$$11x=-11$$

Step 3: Divide by 11

x=-11/11​
$$x=-1$$

Explanation

The correct answer is:

2 is abscissa and 4 is ordinate

In an ordered pair (x, y), x is the abscissa (the value on the x-axis) and y is the ordinate (the value on the y-axis).

Explanation

The square root of 169 is 13, since 13 multiplied by 13 (13²) equals 169.

Explanation

(7^a) (7^b) = (7^c) (7^d)

Using the property of exponents, we get:

7^(a+b) = 7^(c+d)

Equating the exponents, we get:

a + b = c + d

Rearranging the terms, we get:

d = a + b - c

Explanation

Given:

x - 4 = 11

Add 4 to both sides:

x = 15

Now, find x - 8:

x - 8 = 15 - 8

= 7
