I have having a problem with this equation 3(-2-3x) = -9x-4

inn [45]

Answer:

3(-2-3x) = 9x-4

-6-9x = 9x-4

-6+6-9x = 9x-4+6

-9x = 9x+2

-9x-9x = 9x-9x+2

-18x = 2

-18x÷(-18) = 2÷(-18)

x = -(1/9)

Thank you

Which set of ordered pairs does not represent a function? \{(5, -9), (6, -6), (-3, 8), (9, -6)\}{(5,−9),(6,−6),(−3,8),(9,−6)} \{

Nady [450]

Answer:

$\{(-6, -4), (4, -8), (-6, 9), (1, -3)\}$

Step-by-step explanation:

Given

$\{(5, -9), (6, -6), (-3, 8), (9, -6)\}$

$\{(-6, -4), (4, -8), (-6, 9), (1, -3)\}$

$\{(1, -1), (-5, 7), (4, -9), (-9, 7)\}$

$\{(8, -9), (-3, -6), (-4, 4), (1, -5)\}$

Required

Which is not a function

An ordered pair is represented as:

$\{(x_1,y_1),(x_2,y_2),(x_3,y_3),..........,(x_n,y_n)\}$

However, for the ordered pair to be a function; all the x values must be unique (i.e. not repeated)

<em>From options (a) to (d), option (b) has -6 repeated twice. Hence, it is not a function.</em>

Fill in the missing reason in proof.

KiRa [710]

Answer:

Step-by-step explanation:

<u>As per steps given the congruent pairs are:</u>

AB and AC
BD and CD
Angle B and angle C

So two sides and included angle - it represents side-angle-side or SAS congruency theorem

I need to find the simplest form of 88 ---- 90

hram777 [196]

Given

$\frac{88}{90}$

So,

$\frac{88}{90}=\frac{2\cdot44}{2\cdot45}=\frac{44}{45}$

So, the simplest form of 88/90 is 44/45
