Answer

$3

Step-by-step explanation:

To find the x value, you want to cancel out the y terms in the equations. To do so, multiply (2x+5y=6) by 2, and (-x+2y=-3) by -5. This gives you

4x+10y=12

5x-10y=15

You can then cancel out the y terms and add the other terms from the 2 equations together to make

9x=27

You then divide 27 by 9 to get 3 as the value for x.

A person’s retirement account of $30,000 earns 4% each year. Which value would represent the base of the exponential function th
vivado [14]
Well, your probably gonna not go with 30,000 because it stands out like a sore thumb. and 4% is = to .04 So that would be my likely guestimation. 1.04 is probably the answer. in high school you would do 30,000(1+.04/1
)^1*1 
 
and if you were to simplify
30,000(1+.04)
or
30,000(1.04)
So i would say 1.04 is the answer

Solve for xxx. Write the smaller solution first, and the larger solution second.
____ [38]

Answer:

x=-5\text{ or }x=2

Step-by-step explanation:

We have been given an equation x^2+3x-10=0. We are asked to find the solutions of our given equation.

We will use splitting the middle term method to solve quadratic equation.

We will split middle term of our given equation into parts such that whose product is -10 and whose sum is 3.

We know that such two numbers are 5\text{ and }-2.

x^2+5x-2x-10=0

(x^2+5x)+(-2x-10)=0

x(x+5)-2(x+5)=0

(x+5)(x-2)=0

Using zero product property, we will get:

(x+5)=0\text{ or }(x-2)=0

x+5=0\text{ or }x-2=0

x=-5\text{ or }x=2

Therefore, the solutions for our given equation are x=-5\text{ or }x=2.

-10 - 2n  =   -2 • (n + 5)

 Solve :    -2   =  0

Solve  :    n+5 = 0  

Subtract  5  from both sides of the equation :  

               n = -5
