Since E is a midpoint, we can set de and ef equal to each other to find the value of x. 

6x = 3x + 6
3x = 6
x = 2

Then we can plug in x=2 and find that both de and ef are 12. Then since E is the midpoint of df, we can add de and ef to find the value of df. 

12 + 12 = 24

Determine the slop of the linear function
Tasya [4]

Answer:

y = 5x.

Step-by-step explanation:

Read the table from top to bottom.  You'll see that each time x increases by 1, y increases by 5.  We know immediately that the slope of this line is m = rise/run = 5/1 = 5.

Using the first point (2, 10), we see that y = 10 when x = 2.  Fit this info into the slope-intercept form of the equation o a straight line:

y = mx + b becomes 10 = 5(2) + b, or b = 0, and the final equation is y = 5x.

I need help on this math question?​
oksian1 [2.3K]

Answer: C

Step-by-step explanation:

from the expression, (⁵/₈)⁻²

Recall from the laws of indicies,

a⁻¹ = ¹/a , it is called reciprocal law in indicies.

Therefore,

(⁵/₈)⁻² = ¹/(⁵/₈)²

        = ¹(²⁵/₆₄)

Therefore, to resolve this, it will be

      1 ÷ ²⁵/₆₄

        = 1 ˣ ⁶⁴/₂₅

        = ⁶⁴/₂₅

The answer is ⁶⁴/₂₅ which is C in the provided options.
