10x-2=4x-8
-4x -4x
6x-2=-8
+2 +2
6x=-6
divide by six on both sides
x=-1

Okay so combine like terms
10x-4x= 6x
2-8= -6

6x=-6
x= -1

Now to check:
10(-1)-2=4(-1)-8
-10-2=-4-8
-12=-12

When p = 12, t = 2, and s = 1/6, r = 18. If r varies directly with p and inversely with the product of s and t, what is the cons

Ilia_Sergeevich [38]

R = kp/st
18 = 12k/(1/6 x 2)
18 = 12k/(1/3)
18 = 36k
k = 18/36 = 1/2

Which number line shows the solution set for |y-9| <12

RUDIKE [14]

Answer:

Option c

$y\geq-3$ or $y \leq 21$

Step-by-step explanation:

The absolute value is a function that transforms any value x into a positive number.

Therefore, for the function $f(x) = |x|$ x> 0 for all real numbers.

Then the inequation:

$|y-9| \leq 12$ has two cases

$(y-9)$ if $y \geq 9$ (i)

$-(y-9)$ if $y < 9$ (ii)

We solve the case (i)

$y \leq 9 + 12\\y\leq21$

We solve the case (ii)

$-y +9 \leq 12\\-y \leq 12-9\\y \geq -3$

Then the solution is:

$y\geq-3$ or $y \leq 21$

ANYONE KNOW THIS PLS HELP

Alona [7]

In left one)
the 3 angles are equal so the sides are equal then we can say
$(3 \div 2) \times x + 6 = (2 \div 5)x + 9$
then x is 30÷11

the right one) is exactly similar
