Answer:
y = -4
Step-by-step explanation:
y = 6 is line that is parallel to x-axis
So, the required is also parallel to x -axis
The equation of line parallel to x-axis , y = c, where c is y-intercept
y = - 4
Its right,vertical,and complementary.Hope this helps you a bunch!
Answer:
13
Step-by-step explanation:
Its calculate the common difference first.
(95-11)/(n-1).
We also have the sum of these n terms is 689.
So we have the following:
11
+(11+(95-11)/(n-1))
+(11+2(95-11)/(n-1))
+...
+(11+(n-1)(95-11)/(n-1))
This can be re-expressed alittle:
There are (n) amount of 11's in the addition... also 1+2+3+...+(n-1)=(n-1)(n)/2.
So we have the sum is
11(n)+n(n-1)/2×(95-11)/(n-1)
But this equal to 689.
We need to solve the following equation:
11(n)+n(n-1)/2×(95-11)/(n-1)=689
The (n-1)'s in second term can cancel.
11(n)+n/2×84=689
11n+42n=689
53n=689
53n=689
n=689/53
n=13
The width would be 16
4x22=88
1408-88= 1320
22x16x4= 1408
