How many solutions does the system of equations x − y = 7 and y equals the square root of the quantity 3 times x plus 3 end quantity minus 2 have?
Answers
9514 1404 393
Answer:
one solution (11, 4)
Step-by-step explanation:
Both equations describe curves with positive slope. The y-intercept of the line (-7) is less than that of the root function (-2), so the line must intersect the root function in exactly one place. There is one solution.
__
Solved in the conventional way, the equation would become a quadratic, with two solutions. One of them is extraneous. (That is why I prefer a graphical solution.)
Given ...
x -y = 7
y = √(3x +3) -2
We can substitute for y to get ...
x -7 = √(3x +3) -2
x -5 = √(3x +3)
x^2 -10x +25 = 3x +3 . . . . . . square both sides
x^2 -13x +22 = 0 = (x -11)(x -2) . . . . . gives solutions x=11, x=2
The value x=2 does not satisfy the equation ...
x -7 = √(3x +3) -2 ⇒ 2 -7 = √(3·2 +3) -2 ⇒ -5 = 1 (false)

Nellie has a bankruptcy on her credit report and therefore pays higher interest rates on her current loans. She took out a car loan for $45,000 payable for 6 years at an interest rate of 15%. If she had not applied for bankruptcy, she would have been able to take out the loan at a rate of 6%. Approximately how much more in interest over the life of the loan does Nellie have to pay?
a. $68,510.16
b. $53,696.16
c. $32,206.32
d. $14,814.00
Answers
The amount of extra interest that will be paid is $24300
Since Nellie took out a car loan for $45,000 payable for 6 years at an interest rate of 15%, the interest that she will pay will be:
= ($45000 × 6 × 15) / 100
= $40500
On the other hand, if she hasn't applied for bankruptcy, the amount that she will pay will be:
= ($45000 × 6 × 6) / 100
= $16200
Therefore, the difference between the interest will be:
= $40500 - $16200
= $24300
The correct option is $24300. The given options are incorrect.

The vertex of a parabola ( h, k) is the point at which the parabola intersects the axis of symmetry.
Every parabola is symmetric about its axis, which means that if it were folded along its axis, the two parts would match. The fold or line that divides the parabola into two matching halves is called the axis of symmetry.
The axis of symmetry occurs at x = h.

Here’s why:
⸻⸻⸻⸻
[tex]\text{We will convert the equation to slope intercept form.}\\\\2x + 5y = 10\\\rule{150}{0.5}\\\rightarrow 2x + 5y = 10\\\\\rightarrow 2x - 2x + 5y = 10-2x\\\\\rightarrow 5y = 10-2x\\\\\rightarrow 5y = -2x + 10\\\\\rightarrow\frac{5y=-2x+10}{5}\\\\\rightarrow\boxed{y = -\frac{2}{5}x+2}[/tex]

Since [tex]-\frac{2}{5}[/tex] replaces 'm's spot, it is the slope of the given equation.

What is a straight line?A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
We have an equation of the straight line:
y - 3 = 5(x - 2)
For y-intercept:
Plug x = 0
y - 3 = 5(0 - 2)
y = -7
For x-intercept:
Plug y = 0
0 - 3 = 5(x - 2)
x = 7/5
Thus, the y-intercept is -7 and the x-intercept is 7/5 if the equation of the line is y - 3 = 5(x - 2)
