Answer:
y= -x-6
Step-by-step explanation:
slope intercept is as follows
y=mx+b
where m is the slope and b is the y intercept (where the line crosses the y axis)
We can see that the x intercept is -6 which means our equation so far is y=mx-6 and so we just need the slope
To find the slope I will use the slope formula
To use the slope formula you will need two points on the graph. I am going to pick the y intercept and the point next to it
Which means our two points are
(0,-6) and (1,-7)
The slope formula is as follows
(y₂-y₁)/(x₂-x₁)
Plug in our values and get
(-7-(-6)/(1-0)
-1/1
-1 is our slope
which means our final equation is
-x-6
Answer:
-2.35
Step-by-step explanation:
I'm not 100% Sure if that's correct but I'm pretty sure it is!
Answer:
Step-by-step explanation: let the first number be x and the second number be y
according to the condition given
x+y=21
3x-y=43
using elimination method
3x+3y=63
3x-y=43
subtacting both the equations
4y=20
y=20/4
y=5
substituting value of y in eq 1
x+5=21
x=21-5
x=16
therefore x=16 and y=5
the two numbers are 16 and 5
Answer:
Step-by-step explanation:
Yes!
The square root of a number represents the "middle number" possible as a divisor of any given number.
All other factors will have one number above the square root and one number below the square root.
For example consider 80.
The prime factors are 2 * 2 * 2 * 2 * 5. The square root of 80 is about 9, so any factor of 80 must have all the primes under the square root or 1 above and 1 below.
10 * 8 is one such pair. 10 is above 9 and 8 is below it.
=============
I have read the comments made by others. I believe what they are saying is true, but I'm not interpreting the question the same way. I'm looking at these as pairs. The commenter is taking 1 prime at a time. It's a fair way to look at the question. You have to decide how you want to present your answer. You could go either way. That's the problem with some of these questions.
2 to 9 is the reduced ratio
