- the formula of n-th term of an arithmetic sequence.
We have:
Answer: C. 77.4
Answer:
y=-4/13x-28/13
Step-by-step explanation:
m=y2-y1/x2-x1
m=-4-0/6-(-7)
m=-4-0/6+7
m=-4/13
y-y1=m(x-x1)
y-0=-4/13(x-(-7))
y-0=-4/13x-28/13
y=-4/13x-28/13
Answer : x= 15 , 4
steps by step solution : plz see in attachment ✌
Thanks
In order to determine the number of pens present in the container, we need to set up equations from the given in the problem statement. We do as follows:
let x the number of pencils
y the number of pens
From the statement, 9 more pencils then pens in a container,
x = y + 9
From the statement, there are 25 writing utensils in the container in all,
x + y = 25
We use substitution method to calculate for x and y,
y + 9 + y = 25
2y = 16
y = 8
x = 17
Therefore, there are 8 pens in the container and 17 pencils.
The meaning of circumference is to find the distance around a circle or in other words perimeter by using the formula C=2πr or C=<span>πd.
On this case it is asked you to find the circumference of a circle with a diameter of 3 meters, so you will use the formula C=2</span><span>πr.
C=2</span><span>πr
C=2(3.14)(3)
C=18.84 meters
The circumference of the given circle is 18.84 meters.</span>
