If its decreasing it would be C because your line is going down

Graph A represents a constant function; when x increases: y still the same (no change).

Graph B represents a growing function, when x increases , also y increases.

Graph C represents a decreasing (decay) function becasue when x increases, y decreases.

and for Graph D, it is not even a function .

So it would be: Graph C

Option D:

SAS

Solution:

Given $\overline{R S} \ || \ \overline{P Q}$

To prove that $\triangle P Q R \cong \triangle R S P$

In ΔPQR and ΔRSP,

$\overline{R S}\cong\overline{P Q}$ (given side)

$\overline{R S} \ || \ \overline{P Q}$ (given)

By alternative interior angle theorem,

∠PRS ≅ ∠QPR (angle)

By reflexive property of congruence,

$\overline{PR } \cong \overline{PR}$ (side)

Hence by Side-Angle-Side (SAS) congruence rule,

ΔPQR ≅ ΔRSP

Option D is the correct answer.

Hence the missing reason is SAS.

Write an equation to solve for x you are only writing the equations 8x+10 12x-18

djyliett [7]

Answer:

x = 7

Step-by-step explanation:

Required equation

8x + 10 = 12x - 18

Solving for x

12x - 8x = 10 + 18
4x = 28
x = 28/4
x = 7

What is the logarithmic function modeled by the following table?

cupoosta [38]

Answer: option 1.

$log_{4} x$

x f(x)

4 log (4) 4 = 1 ... because 4^1 = 4

16 log(4) 16 = 2 .... because 4^2 = 16

64 log (4) 64 = 3 .... because 4^3 = 64
