Answer:
y= -4x+7
Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.
Let's find the gradient of the line first.
Using the above formula,
Susbt. m= -4 into the equation:
y= -4x +c
Subst. a coordinate to find c.
When x=3, y= -5,
-5= -4(3) +c
-5= -12 +c
c= 12 -5
c=7
Thus the equation of the line is y= -4x +7.
Answer:
An irrational number produces an irrational when added to
Step by step explanation:
To find : What number produces an irrational when added to ?
Solution :
We know that,
It is a rational number as it is repeating.
So, If we add a rational number into a rational number it always gives you a rational number.
To produce an irrational number,
If we add an irrational number to a rational number it always gives you an irrational number.
For example :
An irrational number -
A rational number -
Adding these two number,
This number is non-terminating and non-repeating.
Therefore, An irrational number produces an irrational when added to
dome.

Answer:
Step-by-step explanation:
You must multiply the first two equation which is 5x+1 and x this will give you
5x^2 + x. The bold goes in the first box.
Then do the same thing for 2x+1 and x+1 which will give you 2x^2+2x+x+1 or 2x^2+3x+1. This goes in the second box.
In the last box you will add 5x^2 +x and 2x^2 +3x +1, which gives you 7x^2 +4x +1.
Goes in the last box.
Hope this helps you.
