Help me!!!!!!!!!!!!!
fgiga [73]

For this case we have the following function:

y=\frac{3}{4}x^2

When evaluating x = 2 in the given function we have:

y=\frac{3}{4}(2)^2

Rewriting we have:

y=\frac{3}{4}(4)

y=3

Therefore, the pair ordered for this point is given by:

(x, y) = (2,3)

The ordered pair of the table for x = 2 is:

(x, y) = (2,4)

Therefore, the table is incorrect for x = 2

Answer:

The row in the table is incorrect for:

x=2

Solve equation for z
liraira [26]

Answer:

z = 7

Step-by-step explanation:

9z + 4 / 5 - 8 = 5.4


Add 8 to both sides.


9z + 4 / 5 = 13.4

Multiply 5 by both sides.


9z + 4 = 67


Subtract 4 from both sides.


9z = 63


Divide both sides by 9.


z = 7
