Answer:

y = 96 * (1/2)ˣ   or

y = (-96)*(-1/2)ˣ

Step-by-step explanation:

y=a(b)ˣ

pass (1 , 48):  48 = a * b¹        ab = 48   ...(1)

pass (3 , 12):   12 = a * b³       ab³ = 12   ...(2)

(2)/(1):   ab³/ab = b² = 12/48 = 1/4

b = 1/2 or b = - 1/2

a = 96  or a = -96

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.

I hope this helps!

Answer:

1/12

Step-by-step explanation:

1/4 - 1/6

= 1/12

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: 6700 meters

Step-by-step explanation:

From the question given, we are informed that Gephart is traveling from his house to the history museum and that the distance from home to the history museum is six and seven-tenths kilometers.

In order to know the distance in meters

that he will travel to the museum, we have to multiply the convert the distance given in kilometers to meters. This will be:

1000 meters = 1 kilometer

Therefore, 6 7/10km = (6 7/10 × 1000m)

= 6 7/10 × 1000

= 67/10 × 1000

= 67 × 100

= 6700 meters

He'll travel 6700 meters to the museum.

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:

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:

Option B is true

Step-by-step explanation:

The formula for Cos is Adjacent/hypotenuse. 12 is Adjacent to angle e, and 17 is the hypotenuse.

Answer:

B: cos e = 12/17

Step-by-step explanation:

When using the SOHCAHTOA method you can see that Cos is adjacent over hypotenuse and in the triangle diagram they give you the measurements of the hypotenuse and the adjacent only, so you know that they would be using the cos equation.

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:

(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
