A line passes through (4,5) and (8,9) which equation best represents the line

Mathematics

Nitella [24]3 years ago

Answer:

A

Step-by-step explanation:

In (4,5) the difference between 5 and 4 is 1, the same applies for (8,9), therefore y=x+1 is a linear function of y=x+1

So using this function: (1,2),(2,3),(3,4)(4,5) etc

Write a rule for the linear function in the table.
JulijaS [17]

Answer:

I guess that you want to know the transformations:

We start with:

f(x) = y = 4*x + 3

a)the transformed function is:

f(x) = y = -4*x - 3

So the sign changed.

This means that we go from (x, y) to (x, - y)

This is a reflection over the x-axis which changes the sin of the y component.

b) Now we go to f(x) = 4*x + 3

So the coefficient in the leading term changed.

This is a horizontal contraction:

A horizontal contraction of factor K for the function g(x) is: g(K*x)

In our case, we have:

f(K*x) = 4*(k*x) + 3 = x + 3

4*k*x = x

4*k = 1

k = 1/4

Then the transformation is an horizontal contraction of scale factor 1/4.

Explain how to estimate the quotient using compatible<br>numbers.plz help fast ​
Nadya [2.5K]

<h2><u>PLEASE MARK BRAINLIEST!</u></h2>

Answer:

To estimate the quotient, make the fractions "like" fractions. To do this, you need to make the fractions have the same denominator, and turn them into improper fractions.

Step-by-step explanation:

27\frac{2}{3} = 27 \frac{20}{30}

3\frac{9}{10} = 3\frac{27}{30}

Now the denominators are the same --> they are "like" fractions.

27\frac{20}{30} + 3\frac{27}{30} = ?

27\frac{20}{30} + 3\frac{27}{30} = (27 + 3) + (\frac{20}{30} + \frac{27}{30})

27\frac{20}{30} + 3\frac{27}{30} = (30) + (\frac{47}{30})

27\frac{20}{30} + 3\frac{27}{30} = (30) + (1 \frac{17}{30})

27\frac{20}{30} + 3\frac{27}{30} = 31 \frac{17}{30}

Your answer is 31\frac{17}{30}.

I hope this helps!

Solve the system of equations.
Ipatiy [6.2K]

Answer:

the answer is y= x+7

Step-by-step explanation:

the answer is y= x+7 because you have to move the -2x over to where the 14 is and it becomes positive then you divide 2 by 2x and 14 by 2 then you get the answer
