Answer:
By splitting the line segments into equal parts, we find that the length of the line segment formed by joining the mid-points is 5.5 units.
Step-by-step explanation:
Given lengths show that the length of JK is 5 units, KL is 4 units and LM is 6 units. Let the midpoint of JK be A. This means JK is splited into two equal parts JA and AK. Since the lengths of both the segments are same, it will be 5/2 = 2.5 units.
Now, let the midpoint of LM be B. So, we have two equal line segments LB and BM of length 6/2 = 3 units.
So, the length of the line segment formed by joining A and B will be 2.5 + 3 = 5.5 units

Answer:
(-3, 0) and (1, 0)
(0, 4)
Step-by-step explanation:
x-intercept is the point where y = 0.
y-intercept is the point where x = 0.
or points ...
f(x) = y = -4×|x + 1| + 8
let's start with the y-intercept (x = 0)
y = -4×1 + 8 = -4 + 8 = 4
the y-intercept point (only 1 point) is (0, 4).
for x = 0 the absolute value function contains 0+1. and that is always +1.
the x-intercept(s) :
0 = -4×|x + 1| + 8 (dividing by -4)
0 = |x + 1| - 2
|x + 1| = 2
because of the absolute value we have 2 possibilities :
+(x + 1) = 2
x + 1 = 2
x = 1
and
-(x + 1) = 2
-x - 1 = 2
-x = 3
x = -3
so the points of x-intercept are (-3, 0) and (1, 0)
Answer:
0% 60% 25% 15%
Step-by-step explanation:
So 7 A 2 B 11 C and NO D
So we know 0% chance of D
C has a 60% chance I THINK
A has a 25% chance I THINK
B has a 15% chance I THINK
so yeah good luck
2040 = n/2(20+(n-1)4)
4080 = n(20+4n-4)
4080= 20n +4n^2 -4n
1020 = 4n + n^2
n^2 +4n -1020 =0
use common formula (can't write out so just look at answers. sorry)
which gives answers of n=-34 and n=30. since n can only be positive, n=30 so there are 30 rows. I liked that challenge
Answer:
y = x + 6
Step-by-step explanation:
y = mx + b where m = slope and b = y-intercept (where the line crosses the y axis)
To determine the slope (m) take the difference in y value divided by the difference in x value (also called rise over run, or rise/run)
The difference in y value ( or Δ y) in this graph is from 6 to 10, or 4; the difference in x value ( or Δ x) is from 0 to 4, or 4. So since slope = Δy ÷ Δx, the slope is 1.
So we have y = (1)x + b, and b is where the line intercepts the y axis which is at (0,6), so the equation is y = x + 6.
