We have that
y=x²<span>+5x+3
y=</span>√(<span>2x+5)

using a graph tool
see the attached figure

the solution is 
x=-0.175
y=2.156

therefore

the answer is the option

Answer:

x=-1.216 and x= -0.175

Step-by-step explanation:

Given is a system of equations in x. One quadratic and other square root.

1) y=x^2+5x+3

2) y=\sqrt{2x+5}

Subtracting 2 from 1 we get

x^2+5x+3=\sqrt{2x+5}

Square both the sides

x^4+25x^2+9+10x^3+30x+6x^2 =2x+5\\x^4+10x^3+31x^2+28x+4=0

We find that there are only two real roots and they are approximately

x=-1.216 and x= -0.175

What is the GCF of 24a^3 b and 36ab^2?<br><br> 2ab<br> 4a^3b<br> 12ab<br> 72a^3b^2
Oksi-84 [34.3K]
12ab will be the right answer.

Since 24a^3 = 12ab(2a^2)

And 36ab^2 = 12ab(3b)

5. Amy deposited $7,000 in a bank account earning 3.5% interest, compounded
Semenov [28]

Answer:

Step-by-step explanation:

Given the following data;

Principal = $7,000

Interest = 3.5% = 3.5/100 = 0.035

To find the future value, we would use the compound interest formula;

A = P(1 + \frac{r}{n})^{nt}

Where;

A is the future value.

P is the principal or starting amount.

r is annual interest rate.

n is the number of times the interest is compounded in a year.

t is the number of years for the compound interest.

Substituting into the equation, we have;

A = 7000(1 + \frac{0.035}{n})^{nt}
