Answer:
$ 6.50
Step-by-step explanation:
Based on the given conditions, formulate 3+2 × 1.75
calculate the first two terms 3+3.5
calculate the first two terms 6.5
Answer: 6.5
Answer:
5
Step-by-step explanation:
6-6/7
using pemdas it's:
6/7= 0.857
6-0.857=5.143
5.143 to the nearest whole number is 5
Part (a)
Since point E is on segment AD, this means the slope of ED is the exact same as the slope of AD.
Use the slope formula to calculate the slope of AD.
m = (y2-y1)/(x2-x1)
m = (7-2)/(4-0)
m = 5/4
<h3>Answer: 5/4</h3>
====================================================
Part (b)
The same idea and steps apply as part (a)
<h3>Answer: 5/4</h3>
====================================================
Part (c)
The x coordinates are the same, so we subtract the y coordinates to find the distance between C and D, which is the length of segment DC.
7-2 = 5
<h3>Answer: 5 units</h3>
====================================================
Part (d)
This time, the y coordinates are the same. We'll subtract the x values
4-2 = 2
<h3>Answer: 2 units</h3>
====================================================
Part (e)
Same idea as part (d), just different numbers this time.
2-0 = 2
<h3>Answer: 2 units</h3>
Answer:
Step-by-step explanation:
C11 = (1×1) + (-1×3) = 1-3 = -2
C12 = (1×2) + (-1×4) = 2-4 = -2
C21 = (2×1) + (1×3) = 2+3 = 5
C22 = (2×2) + (1×4) = 4+4 = 8
