One side of the rectangle is 3 times the length of another side. The difference is their length is 14 feet. What is the rectangle's area?
Answer:
A=147 units²
Step-by-step explanation:
Area for rectangle is A=bh (base x height)
Knowing that, we can substitute what we know. So we know that b=3h (3 times the length of the other side), however we also know that b-h=14 (difference between the two is 14).
Let's solve so that we get b by itself for the second equation
b-h=14
b=h+14
Now we have b=3h and b=h+14. We can have them equal each other since they both equal b.
3h=h+14
2h=14
h=7
Now let's go back and plug into b if we know h=7.
b=3h
b=3(7)
b=21
Now we know h=7 and b=21, so let's plug that into the area for a rectangle which is A=bh
A=bh
A=(21)(7)
A=147 units²

-6x+6y=6
-6x+3y=-12
Answer:
x=5 and y=6
Step-by-step explanation:
Answer:
x=5, y=6
Step-by-step explanation:
-6x + 6y = 6
If we divide this by 6 (which we can do because it is an equation), we can simplify this by a lot.
-6x + 6y = 6
-x + y = 1 <-- NEW EQUATION #1
We can also simplify -6x + 3y = -12 by dividing everything by 3.
-6x + 3y = -12
-2x + y = -4 <-- NEW EQUATION #2
Substitution is fairly easy for this problem.
Isolate the variable
-x + y = 1
y = x + 1
Now substitute (x+1) for where you see y in the second equation.
-2x + (x + 1) = -4
-x + 1 = -4
x = 5
Now substitute 5 for x.
-(5) + y = 1
y = 6

Answer:
A system of equations are two or more equations that has to be valid at the same time. It means that the variables of one equation can be substitute in the other equation.
For example we have y=5x−8 and we can substitute this value of y in the other equation
4x+3y=33
4x+3(5x−8)=33 we can solve now for x
4x+15x−24=33
19x=33+24
19x=57
x=5719=3.
y can be obtained from the first equation
y=5x−8
y=5⋅3−8=15−8=7
Then x=3 and y=7.
Step-by-step explanation:
Answer:
x = 3
y = 7
Step-by-step explanation:
y = 5x - 8 ---------------(I)
4x + 3y = 33 ------------(II)
Substitute y = 5x - 8 in equation (II)
4x + 3 (5x - 8) = 33
4x + 3*5x - 8*3 = 33
4x + 15x - 24 = 33 {Combine like terms}
19x - 24 = 33 {Add 24 to both sides}
19x = 33 + 24
19x = 57 {Divide both sides by 19}
x = 57/19
x = 3
Substitute x = 3 in equation (I)
y = 5*3 - 8
y = 15 - 8
y = 7

is (3,4) a solution to the linear equation y=4x-8? Yes or No?
Answer:
Yes
Step-by-step explanation:
To find if the point (3,4) a solution to the linear equation y=4x-8 you need to substitute (3,4) into y=4x-8
(x,y)
(3,4)
x=3 and y=4
Subistute:
4=4(3)-8
4=12-8
4=4 which is correct so the answer is yes (3,4) is a solution for y=4x-8

A technician tests batteries for a battery manufacturer several times each week. She determines that the number of defective batteries is proportional to the number of batteries tested. The table below shows the numbers of batteries the technician tested at two different times during week 1 and the number of defective batteries she found each time.
Battery Test Results for Week 1:
Number Tested: 160, 600
Number Defective: 4, 15
Between week 1 and week 2, the battery manufacturer changed its process. The number of defective batteries is still proportional to the number of batteries tests, but the constant of proportionality is greater. The technician tested 480 batteries during week 2 and found that 18 were defective. By what percent did the constant of proportionality increase? HELP PLEASE
The answer is 50 percent
As per the given data, the constant of proportionality increased by 50%.
What is constant of proportionality?Two numerical sequences, often experimental data, are said to be proportional or directly proportional if their corresponding elements have a constant ratio, which is known as the coefficient of proportionality or proportionality constant.
To solve this problem, we need to compare the proportion of defective batteries in week 1 and week 2. Let's start by finding the proportion of defective batteries in week 1:
For the first test: 4/160 = 0.025
For the second test: 15/600 = 0.025
So in week 1, the proportion of defective batteries was 0.025.
Now let's find the proportion of defective batteries in week 2:
18/480 = 0.0375
The proportion of defective batteries in week 2 is 0.0375.
To find the percent increase in the constant of proportionality, we need to compare the two proportions:
(0.0375 - 0.025)/0.025 x 100% = 50%
Thus, the constant of proportionality increased by 50%.
