I need help please and thank you

Mathematics
1 answer:
Anit [1.1K]3 years ago
6 0

Answer:

4

Step-by-step explanation:

The slope of the line is given. It is 4. Use the equation y=mx+b to answer the other questions.

Substitute 1 in for y, 4 in for m, and 2 in for x and solve for b. The equation would look like 1=4(2)+b.

Solving that equation will give you b=-7

That means the y-intercept is -7.

The equation would then be y=4x-7

Hey there!

A reciprocal might be an unfamiliar vocab word, but the concept is really quite simple.

It's just a flipped fraction! Multiplying the flipped fraction by it's reciprocal gets you one, and that's how you check your answer.

So we have:

Reciprocal of 9/10 is 10/9, because 9/10 times 10/9 = 90/90 = 1

Reciprocal of 1/11 is 11/1, because 1/11 times 11/1 = 11/11 = 1

Reciprocal of 10(remember, it's 10/1) is 1/10, because 10/1 times 1/10 = 10/10 = 1

Hope this helps!

The graph of an exponential function has a y-intercept of 8 and contains the point (3,64). Find the exponential function that de
Brums [2.3K]

Given:

Y-intercept of exponential function is 8.

It contains the point (3,64).

To find:

The exponential function that describes the graph.

Solution:

The general form of an exponential function is

y=ab^x      ...(i)

where, a is initial value or y-intercept and b is growth factor.

Since, y-intercept is 8, therefore, a=8.

Put a=8 in (i).

y=8b^x         ...(ii)

It contains the point (3,64). Put x=3 and y=64.

64=8b^3

Divide both sides by 8.

\dfrac{64}{8}=b^3

8=b^3

2^3=b^3

On comparing both sides, we get

b=2

Put b=2 in (ii).

y=8(2)^x

The functions form of this equation is

f(x)=8(2)^x

Therefore, the required function is f(x)=8(2)^x.
