What is this expression?

Mathematics
1 answer:
Liula [17]3 years ago
4 0

Answer:

2) 4/3

Step-by-step explanation:

(4^-3 * 3^4 * 4^2)/(3^5 * 4^-2)

4^-3 * 3^4 * 4^2 = 4^-1 * 3^4

(4^-1 * 3^4)/(4^-2 * 3^5)

(3^4)/(3^5) = 1/(3^5-4)

(4^(-1))/(4^-2 * 3^(5-4)

(4^-1)/(4^-2 * 3)

4^(-1 - (-2)) / (3)

-1 - (-2) = 1

4/3

What is the function rule for the line?
Salsk061 [2.6K]

Answer:

y =2/3x -2

Step-by-step explanation:

The y intercept is -2

The slope is

m = (y2-y1)/ (x2-x1)

Using the points (0,-2) and  (3,0)

m = ( 0 - -2)/(3 -0)

    = (0+2)/(3-0)

   = 2/3

The slope intercept form is

y = mx+b where m is the slope and b is the y intercept

y =2/3x -2

Solve the equation and find what X is. 9x-7=10
Marysya12 [62]

Answer:

x = 1 8/9 or 17/9

Step-by-step explanation:

Step 1: Add 7 to both sides.

  • 9x - 7 + 7 = 10 + 7
  • 9x = 17

Step 2: Divide both sides by 9.

  • \frac{9x}{9} = \frac{17}{9}  
  • x = \frac{17}{9} = 1 \frac{8}{9}

A. 3(11)-4=33-4=29 and 29 is not equal to 5 so A is not a solution

B.3(5)-4=15-4=11=11  3(3)-4=9-4=5 and 5 is not equal to 2 so B is not a solution

C. 3(2)-4= 6-4=2 2 is not equal to 3 so C is not a solution

D is the answer. 3(5)-4=11 and 3(2)-4= 2
