Answer:
(I can not see the options, so I will answer in a general way)
When we have a system of linear equations:
y = a*x + b
y = c*x + d
We have 3 possible options:
One solution: This happens when the lines intersect only one time, and the solution of the system is the point where the lines intersect.
No solutions: This happens when the lines do not intersect, is the case for parallel lines (lines with the same slope but different y-intercept)
Infinite solutions: This happens when the lines do intersect at infinite points, is the case for two equal lines (so both equations represent the same line)
Now we have the system:
y = m*x + b
y = -2*x + A
We want to find values of m and b, such that this system has no solutions.
Then we know that the lines must be parallel, again, the lines must have the same slope but different y-intercept.
Then we can use:
m = -2, b = A + 1
we will get:
y = -2*x + (A + 1)
y = -2*x + A
This system has no solutions.
Other pair can be:
m = -2, b = A + 3
we will get
y = -2*x + (A + 3)
y = -2*x + A
This system has no solutions.

parallelogram
b= 13 ft. 6 in.
h= 10 ft. 3 in.
Answer:
A=19,926in.
or
A=1660.5ft
Step-by-step explanation:
you convert the feet into inches which gives you a base of 162 inches and a height of 123 inches. Next you multiply your base and height and it gives you an Area of 19,926inches but then if you need to convert the inches back into feet by dividing 19,926 by 12. After you do that you should end up with an area of 1660.5 feet.
A certain forest covers an area of 4800 km^2 . Suppose that each year this area decreases by 5.25% . What will the area be after 6 years? Use the calculator provided and round your answer to the nearest square kilometer.
Answer:
the area after 6 years is 3,473 km^2
Step-by-step explanation:
The computation of the area after 6 years is as follows:
= Area × (1 - decreased percentage)^number of years
= 4,800 km^2 × (1 - 5.25%)^6
= 4,800 km^2 × 0.9475^6
= 3,473 km^2
Hence, the area after 6 years is 3,473 km^2

Caleb is driving on a long road trip, He currently has 11 gallons of gas in his car, Pach
hour that he drives, his car uses up 2 gallons of gas, How much gas would be in the
tank after driving for 4 hours? How much gas would be left after t hours?
Answer:
4 hours = 3
t hours = 11-2t
Step-by-step explanation:
11 gallons = total
2 gallons are used up per hour
So:
11 - 2 * ( number of hours) = number of gallons
11 - (2 * 4) = 11 - 8 = 3
11 - (2t)
Answer:
3 gas
Step-by-step explanation:

The membership in the Lego Club decreased from 120 members in August to 82 members in October. What was the percent decrease from August to October?
Type your answer using the % key. Round to the nearest whole percentage if necessary.
Answer:
72% decrease I...guess?
120 members-60 members=50%
-70 should be approx=60%
-80 should be approx=70%
so 80 is around 70%, so I'd say 82 is 72%
I'm most likely wrong but i dunno maybe im right
Step-by-step explanation:
Answer:
32%
Step-by-step explanation:
((120 - 82) / 120) x 100 = 31.66 %
31.66% to the nearest whole percentage is 32%

whats the next step in solving this equation
Answer:
Using distributive property is the next step in solving the equation
Step-by-step explanation:
-2(4x-1)-7=5
-8x+2-7=5
Answer:
The next step would be to do distributive property.
Step-by-step explanation:
-2(4x-1)-7=5
-8x + 2 - 7 = 5
-8x - 5 = 5
+5 +5
-8x = 10
/-8 /-8
x= -5/4
or
x = -1 1/4

Answer:
because JKML is a parallelogram
=> JK // ML
=> KJM + LMJ = 180⁰
<=> 3x + 20 + 5x - 8 = 180⁰
<=> 8x = 168
<=> x = 21
with x = 21 => L = 4.21 - 1 = 84 - 1 = 83⁰
