Answer:

A function is defined as every x value only has one y value. Since the second row says that when x is 5, y is 6. This means that p = 6

If 9^x=25, what does 3^x equal?

Liula [17]

Answer:

$3^x=5$

Step-by-step explanation:

Given:

$9^x=25$

Rewrite 9 as 3²:

$\implies (3^2)^x=25$

$\textsf{Apply exponent rule} \quad (a^b)^c=a^{bc}:$

$\implies 3^{2x}=25$

Apply the same exponent rule:

$\implies (3^x)^2=25$

Square root both sides:

$\implies \sqrt{(3^x)^2}=\sqrt{25}$

$\implies 3^x=5$

Solve the following systems using the substitution method <br> 3x + 2 y = 13<br> 14x-y=-1

babunello [35]

Answer:

Step-by-step explanation:

14x - y = -1

14x = y -1

14x +1 = y

Substitute into other problem:

3x + 2(14x +1) =13

3x + (28x + 2) = 13

31x + 2 = 13

31x = 11

x = 11/31

Questions 3, 4, and 5.

Sunny_sXe [5.5K]

Answers:

Reason 2) Given. Specifically, the diagram shows that the two angles are adjacent and supplementary, which is why the two angles are a linear pair.
Reason 3) Definition of Linear Pair. As stated above, a linear pair of angles add to 180 degrees (they are supplementary).
Statement 4) $m \angle WZX = 90 \text{ and } m \angle WZV = 90$ since the term "right angle" is another way of saying "90 degree angle"
Statement 5) $\overset{\leftarrow -\rightarrow}{WY} \perp \overset{\leftarrow -\rightarrow}{XV}$ The upside down "T" symbol means "perpendicular". Perpendicular lines form 90 degree angles at the intersection.

Side note: The double arrow over WY and XV in statement 5 is supposed to be an unbroken line.
