Answer:
y = - x - 2
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 5, 4) and (x₂, y₂ ) = (5, - 8)
m = = = -
y = - x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (5, - 8), then
- 8 = - 6 + c ⇒ c = - 8 + 6 = - 2
y = - x - 2 ← is the equation of the line
Answer:
No
Step-by-step explanation:
Let's check the first statement with an example. 2 and 3 are positive numbers and their sum (5) is also positive so his first statement is true.
To check the second statement let's look at the negative numbers -1 and -8 for example. Their sum (-9) is also negative so his second statement is true.
To check the third statement let's look at the numbers 9 and -5. One is positive and one is negative, but their sum (4) is positive, so his third statement is false. However if we look at the numbers 4 and -7, their sum is negative so the third statement is partially false.
Hello There!
The answer you have selected, (D) is correct!
To get the answer you simply add the two fractions together. and 9 + 4 = 13.
13/10 is also called an irrational fraction, the more you know~
Have a great day, and maybe brainliest?
Hey there!
The distance around a circle is its circumference. We are given the radius of the circle. To find the circumference, we need to find the diameter and multiply it by pi. The diameter is twice the radius. We multiply our radius by two..
5*2=10
Then we multiply by 3.14
10*3.14=31.4
Therefore, we will need 31.4 feet of ribbing to go around the rug.
I hope this helps!
First, 300/5 = 60
so, 500/60 = 8.3
so he'd need to work around 8 hours
