Step-by-step explanation:

LHS = 5x+y =5(1)+2= 5+2= 7

RHS = 7

since LHS= RHS

LHS = 7x-2y =7(1)-2(2)=7-4=3

RHS = 3

since LHS=RHS

(1, 2) is a solution to the following system of equations.

Hi there!

»»————-　★　————-««

I believe your answer is:

A) True

»»————-　★　————-««

Here’s why:

I have used a graphing program to graph the lines given.
When they are graphed, the lines intercept at the point (1,2). This means that it is a solution to the system, and the given statement is true.
See the graph attached.

Hope this helps you. I apologize if it’s incorrect.

How many solutions 2x+3y=-3 and 3x + 5y = -9

Sunny_sXe [5.5K]

Since the slopes of the two lines are the not equal, they will have only one solution. The solution will be a point and can be found using the method given below.

We can find the solutions by simultaneously solving the two equations.

From first equation, the value of y comes out to be:

$2x+3y=-3 \\ \\ 
3y=-3-2x \\ \\ 
y= \frac{-3-2x}{3}$

Using this value of y in second equation, we get:

$3x+5( \frac{-3-2x}{3} )=-9 \\ \\ 
9x-15-10x=-27 \\ \\ 
-x=-27+15 \\ \\ 
-x=-12 \\ \\ 
x=12$

Using this value of x, we can find y:

$y= \frac{-3-2x}{3}= \frac{-3-24}{3} =-9$

Therefore, there is only one solution to the given equations is which is (12, -9)

Mr. Hall deposited money into an account in which interest is compounded quarterly at a rate of 2.6%. How much did he deposit if

Amanda [17]

The formula of this equation would be $x_{0}$ * 1.026^16 = 7,160.06
So from this equation we know that $x_{0} = \frac{7,160.06}{1.026^{16} }$
Now we need to find the value of x, we need to multiply $x_{0}$ * 1.026 16 times. Which will bring us to your answer. $4,748.53
