Answer:

<h2>z = 6</h2>

Step-by-step explanation:

4(z+1)=2(z-1)+18\qquad\text{use the distributive property}\\\\(4)(z)+(4)(1)=(2)(z)+(2)(-1)+18\\\\4z+4=2z-2+18\qquad\text{subtract 4 and}\ 2z\ \text{from both sides}\\\\4z-2z+4-4=2z-2z-2+18-4\qquad\text{combine like terms}\\\\2z=12\qquad\text{divide both sides by 2}\\\\z=6

An investment of $500 earns interest at an annual interest rate of 13%. The equation for this investment is B = 500(1.13)t, wher
pickupchik [31]

Answer: C) B= 500(1.101)^{12t}

Step-by-step explanation:

Given : The equation for this investment is B = 500(1.13)t, where B represents the balance and t is the number of years.

For monthly interest , Rate = \dfrac{r}{12}

Time = 12 t  [ 1 year = 12 months ]

As r = 0.13 , so rate = \dfrac{0.13}{12}\approx0.010

Now, the equation will be :

B=500 (1+0.101)^{12t}

\Rightarrow\ B= 500(1.101)^{12t}

Correct option : C) B= 500(1.101)^{12t}

Your answer would be 24 marbles. This is because if you add up all the number of pulls, you get 20, which means we would need to multiply all of the results by 3 to see how many pulls you would get in a bag of 60, and so 8 x 3 = 24. I hope this helps,

What is an equation of the line that passes through the point (1,-3) and is parallel to the line 4x+y=4?
suter [353]

Answer:

y=-4x+1

Step-by-step explanation:

we know that parallel lines have equal slopes

first, we need to put 4x+y=4 into y=mx+b form

4x+y=4

-4x    -4x

y=-4x+4

this means we have a slope of -4

we now know the new slope has to be -4

since we are given a point, we can put this into slope point form

the equation for this is y-y1=m(x-x1) with m posing as our slope

now we plug in

y--3=-4(x-1)

y+3=-4x+4

-3           -3

y=-4x+1

we now know the y-intercept is 1
