n example 3, your friend says that there is enough information to determine the numbers of solutions of the equations $3(5x+2)=1

5x$ and $-2(4y+1)=-8y-2$ once you obtain $15x+6=15x$ and $-8y-2=-8y-2$ . Is your friend correct?

The number of solutions of the equations can't be determined.

<h3>How to illustrate the information?</h3>

It should be noted an equation shows the relationship between the variables. It should be noted that the question is to find the number of solutions.

From the information, 3(5x + 2) = 15x

15x + 6 = 15x

Collect like terms

15x - 15x = - 6

0 = -6

Therefore, it can be see that the friend is incorrect as the number of solutions of the equations can't be determined.

soldier1979 [14.2K]

28% decrease

Solution:

Calculate percentage change

from V1 = 25 to V2 = 18

(V2−V1)|V1|×100

=(18−25)|25|×100

=−725×100

=−0.28×100

=−28%change

=28%decrease

What is the calculation for determining simple interest and compound interest? Borrowing if borrowed $20,000 for 5 years at a 4%
yarga [219]

Answer:

If using simple interest, the formula is:

= Amount * ( 1 + rate * time)

= 20,000 * ( 1 + 4% * 5)

= $24,000

Interest = Balance after 5 years - Investment

= 24,000 - 20,000

= $4,000

Using Compound Interest:

= Amount * ( 1 + rate)^time

= 20,000 * ( 1 + 4%)⁵

= $24,333.06

Interest = 24,333.06 - 20,000

= $4,333.06

What is the equation for 5 units left and 3 units up from f(x)=x
erastovalidia [21]

The new equation after shifting will be:

g(x) = (x+5)+3\\g(x) = x + 8

Step-by-step explanation:

Function trnafomations upward and left are defined as:

Upward:

f(x) => f(x)+b where b is an integer

Left:

f(x) => f(x+b) where b is an integers

Given function is:

f(x) = x

Shifting the function 5 units left

g(x) = f(x+5) => x+5\\g(x) = x+5

Shifting the function upward 2 units

So,

g(x) = (x+5)+3\\g(x) = x + 8

The new equation after shifting will be:

g(x) = (x+5)+3\\g(x) = x + 8
