A student worked out an equation and below is his solution. is the answer correct? If not, where was the error and what is the correct answer?
-4(6-r)=12
-24-4R=12
-4R=36
R=-9
Answer:
His answer is wrong.
Step-by-step explanation:
-4(6-R)=12 <-- Since R is negative, -4 times -R results in a positive so, 4R.
-24+4R=12
+24 +24
--------------------
4R = 36
R= 9

The figures below show sketches of Earl's and Dylan's flower gardens. If the perimeter of each of their gardens is the same, what is the length and width of Earl's garden?
Answer:
[tex] length = 12 ft [/tex]
[tex] width = 8 ft [/tex]
Step-by-step explanation:
Earl's garden:
[tex] length = (x + 6) ft [/tex]
[tex] width = (x + 2) ft [/tex]
[tex] perimeter = 2(length) + 2(width) [/tex]
[tex] perimeter = 2(x + 6) + 2(x + 2) [/tex]
[tex] perimeter = 2x + 12 + 2x + 4 = (4x + 16) ft [/tex]
Dylan's garden:
[tex] length = (2x - 2) ft [/tex]
[tex] width = (x + 4) ft [/tex]
[tex] perimeter = 2(length) + 2(width) [/tex]
[tex] perimeter = 2(2x - 2) + 2(x + 4) [/tex]
[tex] perimeter = 4x - 4 + 2x + 8 = (6x + 4) ft [/tex]
Generate an equation to solve for the value of x.
Since the perimeters of both gardens are the same, therefore:
[tex] 6x + 4 = 4x + 16 [/tex]
Collect like terms
[tex] 6x - 4x = - 4 + 16 [/tex]
[tex] 2x = 12 [/tex]
Divide both sides by 2
[tex] x = 6 [/tex]
Earl's garden:
[tex] length = (x + 6) ft [/tex]
Plug in the value of x
[tex] length = 6 + 6 = 12 ft [/tex]
[tex] width = (x + 2) ft = 6 + 2 = 8 ft [/tex]
Answer:
l: 12ft
w: 8ft

Through (-2,-4), slope = -1/7
Answer:
y = -1/7x -6/7
Step-by-step explanation:
y = mx +b
m = -1/7
y = -1/7x +b
-4 = -1/7(-2)
-4 = -2/7
-4 + -2/7 = b
b = -6/7
y = -1/7x -6/7
You are going on a field trip and need to choose where to go, The zoo charges a $100 fee plus $10 per student. The museum charges $200 plus $5 per student. How many students have to go on the trip to make the museum a better deal
Answer:
21 kids have to go on the trip to make the museum a better deal
Step-by-step explanation:
Zoo: y=10x+100
Museum: y=5x+200
10x+100=5x+200
5x=100
x=20
When 20 kids go on trip the costs will be the same. Therefore, once 21 kids go the museum will be cheaper then the zoo as it is increasing at a rate of 5 dollars
hello I need help with graphing my functions it's y = 2x + 3 but I need to graph it
The variable x is a placeholder for a number
Let's say we replace x with 0
y = 2x+3
y = 2(0)+3
y = 0+3
y = 3
This means x = 0 and y = 3 pair up together. In short, the point (0,3) is on the line.
--------------
Let's repeat for x = 1
y = 2x+3
y = 2(1)+3 ... replace x with 1
y = 2+3
y = 5
So (1,5) is another point on the line
---------------
We can keep this process going to generate as many points as we want. But to graph a linear equation like this, we only need two points at minimum.
Graph both (0,3) and (1,5). Then draw a straight line through them both. The graph is shown below.

The function rule T–4, 6(x, y) could be used to describe which translation?
T–4, 6(x, y) could be used to describe a horizontal translation to the right by 4 units, and a vertical translation up by 6 units
How to describe the translation?The rule is given as:
T–4, 6(x, y)
This can be rewritten as:
(x - 4, y + 6)
The above means that:

Answer:
a. 1/5
b. (3, 3/5)
c. 1/5x = y
Step-by-step explanation:
Remember: (x, y)
0.5 = 1/2
(1/2, 1/10) = 1/10 ÷ 1/2 = 1/10 • 2 = 1/5, you can divide y/x = constant of proportionality. 1/10 ÷ 1/2.
1 2/5 = 7/5
(7, 7/5) = 7/5 ÷ 7 = 7/5 • 1/7 = 1/5, y/x = constant of proportionality. 7/5 ÷ 7.
a. 1/5 is the constant of proportionalityb. (3, 3/5) because 3/5 ÷ 3 or 3/5 • 1/3 = 1/5.c. 1/5x = yfind the value of x. PLEASE HELP

2x+108 = 180
2x+108-108 = 180-108
2x = 72
2x/2 = 72/2
x = 36
-------
Notes:
The reason 2x and 108 add to 180 is because they form a straight angleIn step 2 above, I subtracted 108 from both sidesIn the second to last step above, I divided both sides by 2.The general steps to solving any equation is to follow PEMDAS in reverse to isolate the variable.Given : There is a line . It is divided into two parts by another line such that it forms two angles on two sides of the angle which are 2x° and 108° .
To Find : The value of x .
Solution : Given that the two angles are 2x and 108° . So , we know that the measure of a straight line is 180° . So the sum of the two angles will be also equal to 180°. That is ;
[tex]\large\boxed{\red{\bf \angle 1 + \angle 2= 180^{\circ}}}[/tex]
Where [tex]\angle[/tex]1 and [tex]\angle[/tex]2 are two angles .⇒ 2x° + 108° = 180° .
⇒ 2x° = 180° - 108° .
⇒2x° = 72°.
⇒ x =[tex]\sf \dfrac{72}{2}[/tex]
⇒ x = 36° .
Hence the value of x is 36° .
