4 0

Answer:

none of em. Cause they either need to have the same number on each side, or like for example the variables and coefficient need to be same like 6x = 6x. but none of em seem to match. You probably didnt write it correctly

Triangle ABC had a perimeter 18 cm

Anna007 [38]

Answer:

Use pythagoreum theorem to determine whether it is or isn't since I'm not really sure myself but here's my calculations.

Step-by-step explanation:

We need to find AC.

Picture a triangle called ABC. AB is one side and BC the other while AC is the hypotenuse.

AC=

$ac = \sqrt{ab ^{2} + {bc}^{2} } \\ ac = \sqrt{ {7}^{2} } + {3}^{2} \\ ac = \sqrt{49 + 9} \\ ac = \sqrt{58 } \\ ac = 7.6$

Round up the 7.6 to a whole number and you get AC=8. To get perimeter of a triangle simply add the sides together to get 18.

Not really sure about my answer but hope this helped.

Use the table to determine the degree of the power function.

valkas [14]

9514 1404 393

Answer:

Step-by-step explanation:

The x-values in the table are evenly-spaced, so we can determine the degree of the function by looking at successive differences of the f(x) terms.

f(x): -23, -4, 3, 4, 5, 12, 31

first differences: 19, 7, 1, 1, 7, 19

second differences: -12, -6, 0, 6, 12

third differences: 6, 6, 6, 6

The third differences are constant, so the function values can be matched by a third degree polynomial.

_____

Additional comment

The first differences are found by subtracting the function value from the next one. Likewise, the second differences are found by subtracting each first-difference value from the next one. An so on for the third differences.

The level at which the differences are constant is the degree of the polynomial that will match the function values. (Compare this to what you know about an arithmetic sequence, where first differences are constant and the sequence is described by a linear (degree 1) equation.)

Need help with this if you can explain please do if not then just and answer is okay

pshichka [43]

Step-by-step explanation:

f(x) = x / (x - 7) = 1 + 7 / (x - 7).

The domain of f(x) depends whether the denominator of the rational expression is non-zero.

When (x - 7) = 0, x = 7.

Hence domain of f(x)

= All real values of x excluding 7. (C)
