Answer:
y = 2x - 4 slope: 2 y intercept: -4
equation of perpendicular line pass (1,2): y = -1/2 * x + 2.5
Step-by-step explanation:
4x - 2y = 8
2y = 4x - 8
y = 2x - 4
slope: 2
y intercept: -4
slope of perpendicular line: -1/2
2 = -1/2 * 1 + b
b = 2.5
equation of perpendicular line pass (1,2): y = -1/2 * x + 2.5
Answer:
The missing side length is 27 in
Step-by-step explanation:
see the attached figure
we know that
1 ft= 12 in
step 1
Convert ft to in
2 ft=2*12=24 in
Note ----> the given measure is 13 in instead of 13 ft
step 2
Find the missing side length
The perimeter of a quadrilateral is the sum of its four side lengths
Let
x------> the missing side length
P=x+24+13+15
P=79 in
so
79=x+24+13+15
x=79-52=27 in
The missing side length is 27 in
Answer:
The answer is x = -3.
Step-by-step explanation:
N=12-2 is the answer of this question
7 is 1/4 of 28, so 7 is 25% of 28.
The drop from 28 to 7 is a drop of 21.
21 is 3 times 7, so 21 is 3 times 25%.
Answer: It is a 75% decrease.
