Hi!
4x+4=2x+10
Move all the numbers to the right and all the variables to the left, using the opposite operation:
4x-2x=10-4
2x=6
Divide both sides by 2:
x=3 (Answer)
Hope it helps!
Enjoy your day!

Answer:
4x+4=2x+10 --> 4x-2x=10-4 --> 2x=6 --> x=6/2 --> x=3/1 --> x=3 Answer.
Find the area of the composite figure.
So in fig 1 :
L = 14m W = 9mArea = L × WArea = 9 × 14Area = 126 m²In fig 2 :
L = 7mW = 16 - 9 = 7mArea= L × WArea = 7 × 7Area =49m² TA = 126 + 49TA = 175 m²The area of the composite figure is,
A = 175 m²
We have to given that,
A composite figure is shown.
In first part,
Lenght (L) = 14m
Width (W) = 9m
Hence, We get;
Area = L × W
Area = 9 × 14
Area = 126 m²
For second part,
Lenght (L) = 7m
Width (w) = 16 - 9 = 7m
Hence, We get;
Area= L × W
Area = 7 × 7
Area =49m²
So, We can formulate;
The area of the composite figure is,
A = 126 + 49
A = 175 m²

why is it important to convert your equation from standard form to slope intercept? How can this help you graph your equation?
Answer:
The slope intercept form is used to find the y-intercept and the slope of a straight line. If you look closely, it is a linear function too; meaning the function can tell you its domain and range.

What is the Area of a Polygon?To find the area of a polygon, decompose the polygon into known shapes and find the area of each shape, then add all.
Thus:
Decomposing the polygon given, we would have rectangle 1 and rectangle 2.
Area of rectangle 1 = length × width = 7 × 10 = 70 ft²
Area of rectangle 2 = length × width = 24 × (21 - 10) = 264 ft²
Area of the polygon = 264 + 70 = 334 ft²

The perimeter of a rectangle is 52 cm. If its width is 2 cm more than one-third of its length, find the dimensions of rectangle.
(A) 12 cm x 4 cm (B) 18 cm x 8 cm (C) 15 cm x 9 cm
Answer:
(B) 18 cm × 8 cmStep-by-step explanation:
Perimeter of a rectangle = 52 cm
2(length + width) = 52 ==> l + w = 26
Let x be the length
width = (x/3) + 2
x + (x/3) + 2 = 26
[(3x + x)/3] + 2 = 26
4x / 3 = 24
4x = 24 (3)
x = 6(3) ==> 18 cm
Width = (18/3) + 2
= 6 + 2 = 8 cm
So, the required dimension is 18 cm x 8 cm.

B. 18 * 8.Step-by-step explanation:
Let the perimeter be:
52 cm.Find the numbers for the perimeter:
For A:
(12 cm + 4 cm) * 2 = 32.That means A is incorrect.
For B:
(18 + 8) * 2 = 52 cm.That means B is correct.
For C:
(15 + 9) * 2 = 48 cm.That means C is incorrect.
Correct choice is B.

Please help for this question what is the function and thanks
Answer:
b) local minimum at [tex]x=\frac{1}{e}[/tex]
c) Graph of the function is convex
Step-by-step explanation:
We are told that [tex]f'(\frac{1}{e})=0[/tex], which implies there is a turning/stationary point at [tex]x=\frac{1}{e}[/tex].
Substituting [tex]x=\frac{1}{e}[/tex] into [tex]f''(x)[/tex] will tell us if the turning point is a minimum or a maximum:
[tex]f''(\frac{1}{e})=\frac{1}{\frac{1}{e} } =e>0 \implies \textsf{local minimum}[/tex]
Therefore, statement a) is false and statement b) is true.
If the function has a minimum turning point, then this implies that the curve is convex. Therefore, statement c) is true.
Extremum = local min and max points.
We have already established that there is a local minimum at [tex]x=\frac{1}{e}[/tex], therefore statement d) is false.
I know this is not needed for this question, but here are the workings to detemine the equation of the function (I've also attached a graph). This supports the answers above.
[tex]\textsf{if} \ f''(x)=\frac{1}{x}\\\\\implies f'(x)=\int f''(x) \ dx \\\\\implies f'(x)=ln|x|+C\\[/tex]
[tex]\textsf{if} \ f'(\frac{1}{e})=0\\\\\implies ln|\frac{1}{e}|+C=0\\\\\implies -1+C=0\\\\\implies C=1\\\\[/tex]
[tex]\implies f'(x)=ln|x|+1\\[/tex]
[tex]\textsf{if} \ f'(x)=ln|x|+1\\\\\implies f(x)=\int f'(x) \ dx\\\\\implies f(x)=xln(x)-x+x+C\\\\\implies f(x)=xln(x)+C[/tex]

How can you find the perimeter of the rectangle by only knowing its area
Answer:
It's not possible to determine the perimeter of a rectangle given only the area. The area of a rectangle depends on two unknowns, the length and the width, so you must be given at least one side of the rectangle along with the area to determine the other side and, thus, the perimeter

It is not possible to determine the perimeter of a figure given its area.
Sarah is planning to take
aerobics classes at a gym.
Non-members pay $8 per
class, while members pay $4
per class and a $20
membership fee. If Sarah
plans to take 6 aerobics
classes, should she become a
member of the gym? Explain
why or why not?
Answer:
Yes
Step-by-step explanation:
Non members - 8*6 = $48
Members - 20+(4*6) = $46
She should become a member of the gym because she will pay $2 less overall.
Answer:
Sarah should become a member. She would be paying a lot less money and be able to take more classes for cheaper
Step-by-step explanation:
Non member amount for 6 classes- $8*6= $48
Member amount for 6 classes- $4*6= 24 ($20 fee) = $44
As you can see above, the cost for 6 classes with a membership is cheaper than without a membership
At a hockey game, a vender sold a combined total of 217 sodas and hot dogs. The number of sodas sold was 59 more than the number of hot dogs sold. Find the number of sodas sold and the number of hot dogs sold
Answer:
sodas sold = 138
hot dogs sold = 79
Step-by-step explanation:
let s = number of sodas sold
let h = number of hot dogs sold
equation 1: h + s = 217
equation 2: h + 59 = s
Substitute equation 2 into equation 1 and solve for h:
⇒ h + (h + 59) = 217
⇒ 2h + 59= 217
⇒ 2h =158
⇒ h = 79
Substitute found value of h into equation 2 and solve for s:
⇒ 79 + 59 = s
⇒ s = 138
answer:
number of hot dogs is 79
number of sodas is 138
explanation:
let the number of hot dogs sold be xthen number of sodas is x + 59solve:
Therefore:
x + x + 59 = 217
2x = 158
x = 79
79 hot dogs
now find [ x + 59 ], number of soda's79 + 59
138 sodas

The fifth bus had 4/5 of the seats filled.
1/8 of all the passengers on the buses were adults.
How many adults went on the field trip with the 5th grade classes?
1/8 x 5 = 5/8
5/8 of the passengers were adults :)

Solve:
[tex] \frac{ - 4}{0} = m[/tex]
When a slope has a run (x) of 0, the slope is undefined.
Answer:
-4 / 0
Step-by-step explanation:
Given the following question:
(-5, 8), (-5, 4)
In order to find the answer to this question we will use rise over run, substitute the values, and then solve.
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
(-5, 8), (x1, y1)
(-5, 4), (x2, y2)
4 - 8 = -4
-5 - -5 = 0
m = -4 / 0
