The equation is positive, so the graph should be on the other side. One way to check this would be to plug a number in the equation,
where x = -2
y= 3/2(-2)-1
y= -3-1
y= -4
on the graph you plotted you have y = 2 where x = -2

arsen [322]

Answer:

$\frac{-4}{3}$ =g-1(4)

Step-by-step explanation:

x=3y+8 ---> y= $\frac{x-8}{3}$

y= $\frac{(4)-8}{3}$

$\frac{-4}{3}$

how many liters of glycerin should be added to 12 Liters of an 8% glycerin solution so that the resulting solution contains 16%

mojhsa [17]

Answer:

1.14 liters

Step-by-step explanation:

We have 8% glycerin solution and we need to make it 16% glycerin solution [more concentration].

When we add "x" liters, we add glycerin as well as changes the total. in 12 Liters, there is 12 * 0.08 = 0.96Liters of glycerin. How much we need to add to this??

Note, 16% = 0.16

We can write a Ratio as shown below, cross multiply and solve for x:

$\frac{0.96+x}{12+x}=0.16\\(12+x)(0.16)=0.96+x\\1.92+0.16x=0.96+x\\1.92-0.96=x-0.16x\\0.96=0.84x\\x=1.14$

We need to add around 1.14 liters

Someone help.I'm new i suck at math.Pleaseweee 50 points?

MrMuchimi

Answer:

45°

Step-by-step explanation:

Let's understand "supplement" and "complement" -- basics of geometry of angles.

When we say two angles, a & b, are supplementary, we mean that both ADD up to 180.
When we say two angles, a & b, are complementary, we mean that both ADD up to 90.

If we have given an angle, such as "x", to find its supplement, we subtract the angle from 180. Similarly, we would need to subtract the angle x from 90 if we were to find the complement of the angle.

We want to find complement of 45, so we subtract 45 from 90 to get:

90 - 45 = 45°

Hence, the complement of a 45° angle = 45°
