mina [271]

Answer:

$887,761.38

Step-by-step explanation:

The principal amount the home is valued is $375,000 and it increases at a rate of 9% a year which is 0.09 and the amount of time it grew is 10 years. Therefore:

A_{final}=375000(1+0.09)^{10}=375000(1.09)^{10}=887761.38

After 10 years the house is worth $887,761.38 if this trend continues

ivann1987 [24]
In the process of photosynthesis, one of the most important ingredient would be sunlight. Therefore, those aquatic plants that are near the surface would be able to produce the most sugar. This is because they can easily absorb sunlight compared to those that are located deeper in the water. Hope this helps.

What is the solution for the system of equations?<br><br> -4x+y=-2<br> y+5=-6x
Aliun [14]

Answer:

(-3/10,-16/5)

Step-by-step explanation:

One way to solve a system of equations is by elimination.  We can take one equation and subtract the other equation from it to cancel out on of the variables making the equation into something we can solve.  In this case the Y's will cancel out because we have 1 Y in each equation

-4x+y=-2

6x+y=-5 subtract

-4x-6x=-10x

y-y=0

-2-(-5)=3

so our equation is -10x=3 and we can solve for x giving us x=-3/10

now we can plug -3/10 in for x into either of the original equations and solve for Y

y+5=-6(-3/10)

y+5=9/5

y=-16/5

so our answer is (-3/10,-16/5)

I hope this helps and please don't hesitate to ask if there is anything still unclear!
