Answer:

It shows a contradiction because (a − 4b) / b is a rational number and √5 is an irrational number.

Step-by-step explanation:

A rational number can be written as a ratio of two integers.

An irrational number cannot.

I need help with this math lesson ​
irinina [24]

Answer:

9,375

Step-by-step explanation:

Each number is multiplied by 5 to get the next number. We can see this by testing multiple number on this set of data.

3*5=15

15*5=75

75*5=375.

Thus, to find the next term in the set of data, we must multiply the last number that we are given by 5.

1875*5=9,375

The next number is 9,375

Hope this helps!

Write the slope intercept form of the graph plz
Mama L [17]

Answer:

y = 3x - 6

Step-by-step explanation:

slope intercept form is: y = mx + b

m is your slope, so figure it out by doing rise/run

you rise 3, over one which is 3/1, but simplifies to 3

b is your y-intercept, find it by seeing where the line crosses the y-axis, which is -6

therefore, your answer is: y = 3x - 6

A line that has a rise of -34 and a run of 20.
aleksandr82 [10.1K]

Answer:

y=-1.7x-34

Step-by-step explanation:

An equation of a line is given y=mx+c, where m is the gradient or \frac{Rise}{Run}

The rise indicates the change in value of y (vertical change in the graph).

The run indicates the change in value of x (horizontal change in the graph).

Let point 1 of the graph be (x,y) = (0,-34) and point 2 be (x,y) = (20,0).

 m =\frac{Rise}{Run} \\  =\frac{-34}{20}\\  =-1.7

Substitute point 1 into the graph to get the constant c.

y=mx+c

-34=(-1.7)*(0)+c

c=-34

∴ The equation of the line is, y=-1.7x-34
