Which statement is true about the equation 4.5z = 4.5z – 4.25 + 6.25? (1 point) It has no solution. It has one solution. It has

MakcuM [25]

I think it would be it has no solutions, because if you solve for z, the z's cancel each out and you would get 0=2 with is not true, so there would not be any solutions.

4.5z=4.5z-4.25+6.25
4.5z-4.5z=-4.25+6.25
0=2
no solution

Pls help: without graphing determine whether the function represents exponential growth or exponential decay. Then find y-interc

Mrac [35]

Given

$0.99(\frac{1}{3})^x$

To determine whether the function represents exponential growth or exponential decay, and the y-intercept.

now,

It is given that,

$0.99(\frac{1}{3})^x$

The exponential functions are of the form,

$y=ab^x$

If a is positive and b is greater than 1, then it represents exponential growth.

And, if a is positive and b is greater than 0 and less than 1, then it represents exponential decay.

Since b=1/3<1.

Then, the given function represents exponential decay.

The y- intercept of the function is,

$\begin{gathered} y=0.99(\frac{1}{3})^x \\ \text{When x=0.} \\ y=0.99(\frac{1}{3})^0 \\ y=0.99 \end{gathered}$

Hence, the y-intercept is 0.99.

U = y / xk <br><br> solve for x

Svetradugi [14.3K]

Answer:

x = y/ (Uk)

Step-by-step explanation:

U = y / xk

Multiply each side by xk

Uxk = y / xk *xk

U xk = y

Divide each side by Uk

U xk/ (Uk) = y/ (Uk)

x = y/ (Uk)

Aleksandr-060686 [28]

Given :

The CHS basketball team scored a total of 70 points in their last game. They made 25 total shots. Some of the shots were worth two points and some of the shots were three-pointers.

To Find :

A system of equations to model the situation.

Solution :

Let, number of two pointer shots are x and three pointers are y.

So, x + y = 25 .......1)

Total points scored , S = 70.

$2x+3y=70$ .......2)

Solving equation 1 and 2 , we get :

$2x+3(25-x)=70\\\\x=5$

y = 25 - 5 =20

Therefore, total numbers of two and three pointers are 5 and 20 respectively.

Hence, this is the required solution.
