Which statement best explains whether these ordered pairs represent a function (-4,2), (6,7), (-8,3),(9,10),(12,14), (6,9)

1 answer:

3 0

These points do NOT represent a function.

In a function, all of the individual inputs only have one output. However, take a look at the input of 6. There are 2 different outputs for the 6. We have a (6, 7) and a (6, 9). This makes the relation not a function.

Describe the graph of 2x + y = 11 and 2x + y = 2. Determine the number of solutions.

Alexandra [31]

Answer:

$\mathrm{No\:Solution}$

Step-by-step explanation:

By using comparing the left hand side of the two given equations we have:

$\begin{bmatrix}2x+y=11\\ 2x+y=2\end{bmatrix}\\\\\begin{bmatrix}11=2\end{bmatrix}\\\\11=2\:\mathrm{\:is\:false,\:therefore\:the\:system\:of\:equations\:has\:no\:solution}$

8x-5y= 14<br> – 5х+бу = -3

podryga [215]

Answer:

y= 34/23

x= 123/46

Step-by-step explanation:

Solve for x

8x-5y= 14

x= 14/8 +5/8y

Sub x into second equation

– 5х+бу = -3

-5(14/8 +5/8y) + 6y= -3

-29/4 +23/8y = -3

y= 34/23

Sub y into any equation and solve for x

8x=483/23

x= 123/46

In the Exercises below, find the scale factor. Then list all pairs of congruent angles and write the ratios of the corresponding

nadezda [96]

Answer:

8) scale factor: 3

angles Q & L, S & N, r & M

sides 10 x 3 = 30, 6 x 3 = 18, 13 x 3 = 39

9) scale factor: 0.4

angles B & F, C & G, D & H, A & E

sides 9 x 0.4 = 3.6, 7.5 x 0.4 = 3, 10 x 0.4 = 4, 12 x 0.4 = 4.8
