Find the slope of the line whose equation is 9x + 5y = 1. -9/5 -5/9 1/5

-9/5

Step-by-step explanation:

The usual formula of a line is  y = mx + b, where m is the slope and b is the y-intercept.

Knowing this, we need to convert our equation into that form to find our m.

9x + 5y = 1

We subtract 9x on both sides:

9x + 5y - 9x = -9x + 1

5y = -9x + 1

Now we multiply by 1/5 on both sides:

5y * 1/5 = (-9x + 1) * 1/5

y = -9/5x + 1/5

Therefore, the slope of the line is m = -9/5

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
