Alice invests $5000 in two certificates of deposit; the interest on the first certificate is 4%, and the interest on the second

is 5%. Let's denote the amount she invests in the first certificate by x. Then the amount she invests in the second certificate is
.
The interest she receives on the first certificate is



,
and the interest she receives on the second certificate is



.
So a function that models the total interest she receives from both certificates is
y =

Select the two values of x that are roots of this equation x^2-5x+2=0
Nataly [62]

The roots of the equation is x = 4.56 OR x = 0.44

<h3>Quadratic equation</h3>

From the question, we are to determine the roots of the given equation

The given equation is

x² -5x +2 = 0

Using the formula method,

x =\frac{-b \pm \sqrt{b^{2}-4ac } }{2a}

In the given equation,

a = 1, b = -5, c = 2

Putting the values into the formula,

x =\frac{-(-5) \pm \sqrt{(-5)^{2}-4(1)(2) } }{2(1)}

x =\frac{5 \pm \sqrt{25-8} }{2}

x =\frac{5 \pm \sqrt{17} }{2}

x =\frac{5 + \sqrt{17} }{2} OR x =\frac{5 - \sqrt{17} }{2}

x =\frac{5 + 4.12}{2} OR x =\frac{5 - 4.12}{2}

x =\frac{9.12}{2} OR x =\frac{0.88}{2}

x = 4.56 OR x = 0.44

Hence, the roots of the equation is x = 4.56 OR x = 0.44

Solve algebraically. <br> 3x + y =3 <br> Y = 2x - 7
Annette [7]
<span>3x + y =3 
Y = 2x - 7

substitute </span>Y = 2x - 7 into  3x + y =3 
3x + y =3 
3x +2x - 7 =3 
5x = 10
x = 2

Y = 2x - 7 = 2(2) - 7 = -3

answer
(2, -3)

Quadratic equations and functions. <br> n^2+2n-15=0
sveta [45]

Answer:

n = -5, 3.

Step-by-step explanation:

n^2 + 2n - 15 = 0

Let's check if we can factor this quadratic:

We need 2 numbers whose product is -15 and whose sum is +2.

There are 2 such numbers and they are +5 and -3, so the factors are:

(n + 5)(n - 3) = 0.

n + 5 = 0 or n - 3 = 0

therefore the zeroes are -5 and 3.
