Answer:

$14.70

Step-by-step explanation:

Find the 30% decrease:

21*0.3 = 6.3

Find new price:

21-6.3 = 14.7

Answer:

$14.7

Step-by-step explanation:

First, we need to convert the percentage to a decimal. 30% = .30

Now we multiply the price times the decimal, 21 x .30 = 6.3

We subtract this amount from the previous cost. 21 - 6.3= $14.7

Answer:

BC=3root7

CD=root58

Step-by-step explanation:

According to Pythagorean theorem, in a right triangle,a^2+b^2=c^2. a, b are two legs of right triangle. Cis the hypotenuse

12^2-9^2=63

BC=root63=3root7

BD^2-BC^2=CD^2

121-63=CD^2

CD=root58

Answer:

Choice A

Step-by-step explanation:

There should be an open circle at 0 since there is no equals in the inequality

n is greater than zero so the line goes to the right.

Choice A

Answer: I believe it is A.

Answer:

√157 units or about 12.53 units

Step-by-step explanation:

Equation of circle: (x-h)²+(y-k)²=r²

Center: (h,k) -> (2,2)

Equation so far: (x-2)²+(y-k)²=r²

Plug in (-9,-4) to find r: (-9-2)²+(-4-2)²=r² -> 121+36=r² -> 157=r² -> √157=r

Therefore, the radius of the circle is √157 units or about 12.53 units

Answer:5.9

Step-by-step explanation: Clarification from teacher

Answer:

The first step is to replace the y in y-x=15 with 7x (we can do this because the first equation tells us that they're equal)

solve and get

(2.5,17.5)

or x= 2.5 y=17.5

Step-by-step explanation:

The first step is to recognize that y=7x which means that we can just replace the y in the second equation with 7x

7x-x=15

6x=15

x=2.5

Then we can solve for y

y=7(2.5)

y=17.5

Answer:

7-6x+15=-3x-7

29=3x

x=29/3

the asnwer is D

Answer: The answer is x=[tex]\frac{-3-\sqrt{65} }{4}[/tex], [tex]\frac{-3+\sqrt{65} }{4}[/tex]

Step-by-step explanation:

1) You can solve a situation like [tex]ax^2+bx+c=0[/tex] using the quadratic formula

[tex]x=-b[/tex]±[tex]\sqrt{b^2-4ac}[/tex] / 2a

2) Apply that to the problem and we get x= -3±[tex]\sqrt{3^2-4*2*(-7)}[/tex]/2*2

3) Solve what's inside the square root and what's at the denominator --> x=-3±[tex]\sqrt{65}[/tex]/4

4) separate the solutions ---> [tex]x=\frac{-3+\sqrt{65}}{4} , \frac{-3-\sqrt{65}}{4}[/tex]

5) Your final solutions are [tex]x=\frac{-3+\sqrt{65}}{4} , \frac{-3-\sqrt{65}}{4}[/tex]

Answer:

(x+3)/(x-4)

Step-by-step explanation:

[2x²/(x-4)(x-3)] - [x²+9/(x-4)(x-3)] =

(x²-9)/(x-4)(x-3) =

(x+3)(x-3)/(x-4)(x-3) =

x+3/x-4

Answer:

2x²/x² - 7x + 12 - x² + 9/x² - 7x + 12

2x²/x² simplifies to just 2 (the x²s cancel out)

2 - 7x + 12 - x² + 9/x² - 7x + 12

add like terms: (2 + 12 + 12) + (-7x - 7x) - x² + 9/x²

= - x² - 14x + 9/x² + 26

Answer:

c) y+4=3(x+1)

Step-by-step explanation:

Answer:

C. [tex]y+4=3(x+1)[/tex]

Step-by-step explanation:

Hi there!

What we need to know:

1) Determine the slope of the line

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where the given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

Plug in the points (-1,-4) and (2,5)

[tex]=\frac{5-(-4)}{2-(-1)}\\=\frac{5+4}{2+1}\\=\frac{9}{3}\\=3[/tex]

Therefore, the slope of the line is 3. Plug this into [tex]y-y_1=m(x-x_1)[/tex] :

[tex]y-y_1=3(x-x_1)[/tex]

2) Plug the point (-1,-4) into [tex]y-y_1=3(x-x_1)[/tex]

[tex]y-(-4)=3(x-(-1))\\y+4=3(x+1)[/tex]

Therefore, the correct answer is C.
