Step-by-step explanation:

what value of x makes this equation true , use numerals instead of words.

-2x+3=-15

-2x + 3 = -15

-2x = -15 - 3

-2x = -18

x = -18 : (-2)

x = 9

--------------------

check

-2 * 9 + 3 = -15

-18 + 3 = -15

-15 = -15

<u><em>the answer is good</em></u>

Answer:

n=2.5

Step-by-step explanation:

(2n + 4) + 6 = -9 + 4(2n + 1)
2n+10=-9+8n+4
2n+10=8n-5
8n-2n= 10+5
6n=15
n=15/6

The table represents the function f (x) = 3x-1

Reika [66]

Answer:

a=-16, b=11, c=23

Step-by-step explanation:

The function that represents the table is

$f(x) = 3x - 1$

We substitute x=-5 to find the value of a.

$a = f( - 5) = 3( - 5) - 1$

We evaluate to obtain:

$a = - 15 - 1 = - 16$

To find the value of b, we substitute x=4,

We get:

$b = f(4) = 3 \times 4 - 1 \\ b = 12 - 1 \\ b = 11$

To find c, we plug in x=8,

$c = f(8) = 3(8) - 1 \\ c = 24 - 1$

$c = 23$
