What is the equation of the graph shown?​

Mathematics
1 answer:
OlgaM077 [116]3 years ago
5 0

<em>Greetings from Brasil...</em>

As we have a line, the function will be given by the expression:

F(X) = AX + B

where

<em>A = ΔY/ΔX</em>

<em>B = where the line intersects the Y axis</em>

Looking at the graph we have already concluded that

B = - 3

A = ΔY/ΔX

A = (5 - 3)/(4 - 3)     see attached picture

A = 2

So,

F(X) = AX + B

<h2>F(X) = 2X - 3</h2>

Answer:

for #1 its the 1st and 4th box

for # 2 it's 13.5 and 20.25

Step-by-step explanation:

1st box - 10 ÷ 5 = 2 and 25 ÷ 5 = 5

4th box - 10 x 2 = 20 and 25 x 2 = 50

you have to make sure that you do the same thing for both sides of the equation

6 x 2.25 = 13.5

9 x 2.25 = 20.25

Dilation is an enlarging or shrinking of a math figure using a specific scale factor

multiply your numbers by that given scale factor to give you your answer of option 2

hope this is right I'm not completely positive about the send one.

Help with num 9 please. thanks​
Alik [6]

Answer:

See Below.

Step-by-step explanation:

We want to show that the function:

f(x) = e^x - e^{-x}

Increases for all values of <em>x</em>.

A function is increasing whenever its derivative is positive.

So, find the derivative of our function:

\displaystyle f'(x) = \frac{d}{dx}\left[e^x - e^{-x}\right]

Differentiate:

\displaystyle f'(x) = e^x - (-e^{-x})

Simplify:

f'(x) = e^x+e^{-x}

Since eˣ is always greater than zero and e⁻ˣ is also always greater than zero, f'(x) is always positive. Hence, the original function increases for all values of <em>x.</em>

Principal = 5300=5300 rupees
PSYCHO15rus [73]

Answer:

Using the formula:

A=P+I

where

A is the total amount

P is the principal

I is the Simple Interest

As per the statement:

Principal(P) = 5300 rupees.

rate of interest(r) = 6.5% = 0.065

Total amount(A) = 6678 rupees.

Then using above formula we have;

6678 = 5300+I

Subtract 5300 both sides we get;

1378 = I

or

I = \$1378

We have to find the time period.

Using formula of Simple interest:

I = Prt

where r is the rate of interest (in decimal)

here, r = 6.5% = 0.065

Substitute the given values top find t:

1378 = 5300 \cdot 0.065 \cdot t

⇒1378 = 344.5t

Divide both sides by 344.5 we have;

4  = t

Therefore, the time period t in years is 4 years
