Answer:

x=4

Step-by-step explanation:

5x-7=13

5x=13+7

5x=20

x=20/5

x=4

Answer:

x = 4

Step-by-step explanation:

5x - 7 = 13

add 7 to both sides:

5x - 7 + 7 = 13 + 7

5x = 20

divide both sides by 5

[tex]\frac{5x}{5} = \frac{20}{5}[/tex]

x = 4

Answer:

  (a) $2.857 million

  (b) vertical compression by 1/3; shift left by 6; shift up by 2

Step-by-step explanation:

(a) Find the year difference (2021-2010=11) and put that value where x is. Then do the arithmetic.

  g(11) = (∛(11+6))/3 +2 = (∛17)/3 +2 ≈ 2.57128/3 +2 ≈ 0.857 +2

  g(11) ≈ 2.857 . . . 2021 revenue in millions of dollars

__

(b) For parent function f(x), the transformation ...

  g(x) = a·f(x -h) +k

represents a vertical scaling by a factor of 'a', right shift by h units, and up shift by k units.

Comparing this form to the given g(x), we see ...

  a = 1/3 . . . vertical compression by a factor of 1/3

  h = -6 . . . .right shift 6 units

  k = 2 . . . . up shift 2 units

_____

Additional comment

The vertical scaling is called "compression" when the scale factor is less than 1, and "stretch" when the scale factor is greater than 1. Here, the scale factor of 1/3 means the graph is vertically compressed.

Answer:

62/100= 31/50

45/100= 9/20

Step-by-step explanation:

Divide 62 and 100 by two to simplify

Divide 45 and 100 by 5 to simplify

Answer:

62/100 = 31/50

45/100 = 9/20

Step-by-step explanation:

62 and 100 have a greatest common factor of 2. We can use this to break the fraction 62/100 apart:

[tex]\dfrac{62}{100}=\dfrac{2\times31}{2\times50}=\dfrac{2}{2}\times\dfrac{31}{50}=\dfrac{31}{50}[/tex]

We can do the same to simplify 45/100. The greatest common factor of 45 and 100 is 5, so following the same process:

[tex]\dfrac{45}{100}=\dfrac{5\times9}{5\times20}=\dfrac{5}{5}\times\dfrac{9}{20}=\dfrac{9}{20}[/tex]

Answer: 876 feet

Step-by-step explanation:

Given

Carmelit travels 5658 feet horizontally

The slope of trajectory is   [tex]\dfrac{14.6}{94.3}[/tex]

We know, the slope is

[tex]\Rightarrow \text{slope}=\frac{\text{Vertical distance}}{\text{horizontal distance}}\\\\\Rightarrow \dfrac{14.6}{94.3}=\dfrac{Y}{5658}\\\\\Rightarrow Y=876\ feet[/tex]

Hence, the elevation of the top station is 876 feet

Answer:

-3x+5y-3z + 2x-7y+3z

= -x-2y

= x-2y-(-x-2y)

= x + x +2y-2y

= 2x

Answer:

Step-by-step explanation:

Short Answer: No

2(12 - y) = 23- (2y - 1)                    Remove the Brackets on both sides

24 - 2y = 23 - 2y + 1                     Combine like terms on the right

24 - 2y = 24 - 2y                          No matter what you do, the 2ys are going to cancel. When they do, the question goes with them.

You get 24 = 24 Which is true but not relevant.

The other answer you could use is there are an infinite number of answers.

Equality will be maintained, but there is no single answer that works.

Answer:

This equation is an identity, all real numbers are solutions.

Step-by-step explanation:

Simplifying

2(12 + -1y) = 23 + -1(2y + -1)

(12 * 2 + -1y * 2) = 23 + -1(2y + -1)

(24 + -2y) = 23 + -1(2y + -1)

Reorder the terms:

24 + -2y = 23 + -1(-1 + 2y)

24 + -2y = 23 + (-1 * -1 + 2y * -1)

24 + -2y = 23 + (1 + -2y)

Combine like terms: 23 + 1 = 24

24 + -2y = 24 + -2y

Add '-24' to each side of the equation.

24 + -24 + -2y = 24 + -24 + -2y

Combine like terms: 24 + -24 = 0

0 + -2y = 24 + -24 + -2y

-2y = 24 + -24 + -2y

Combine like terms: 24 + -24 = 0

-2y = 0 + -2y

-2y = -2y

Add '2y' to each side of the equation.

-2y + 2y = -2y + 2y

Combine like terms: -2y + 2y = 0

0 = -2y + 2y

Combine like terms: -2y + 2y = 0

0 = 0

Solving

0 = 0

The amount of units that must be sold to a number yields a maximum profit is 600. Hence 600 units will be the correct option.

To find the maxima of any function it needs to differentiate with respect to the dependent variable and equate with zero to get stationary points.

After achieving the stationary points it needs to put on the double derivative of that function to check whether it's maxima or minima.

If the double derivative got negative then it will be maxima.

Given that function

f(x) = -0.001(x-600)² + 90

By differentiation

[tex]$f'(x)$[/tex] = -0.002(x - 600) + 90

Now equate with zero

-0.002(x - 600) + 90 = 0

x - 600 = 0

x = 600

Now checking the x at double derivative

[tex]$f''(x)$[/tex] at x = 600 it is coming out to -0.002 which is negative Hence, the 600 units will be the correct answer.

Answer:

Step-by-step explanation:

Solution:

Rewriting input as fractions if necessary:

9/10, 1/4

For the denominators (10, 4) the least common multiple (LCM) is 20.

LCM(10, 4)

Therefore, the least common denominator (LCD) is 20.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

9/10 = 9/10 × 2/2 = 18/20

1/4 = 1/4 × 5/5 = 5/20

Answer:

Won't it just be 60, because it's an equilateral triangle.

Step-by-step explanation:

60 + 60 = 120

180 - 120 = 60

11x - 6 = 60

11x = 66

x = 66/11

x = 6

Let's substitute.

11(6) - 6 = 66 - 6 = 60

Answer:

$108

Step-by-step explanation:

The computation of the total profit is shown below:

Given that

1 box = $12

18 boxes = 12×18 = $216

So

Total = 18×65 = 1170 pens

Now Cost price, Cp = $216

Also,

3 = $1

So,

= 378 ÷ 3

= $126

Now

= 1170-378

= 792 pens remaining

4 = $1

So,

792

= 792 ÷ 4

= $198

Now

Total selling price, sp = 126+198 = $324

So finally

Profit = Sp - Cp

= $324 - $216

= $108

Answer: See explanation

Step-by-step explanation:

1. Complementary (adds up to 90°)

2. Neither

3. Supplementary (ads up to 180°)

4. Adds up to 90° since its complementary

22 + 4x = 90

Subtract 22 from both sides

4x = 68

Divide both sides by 4

x = 17

5. Adds up to 90° since its complementary

65 + x + 2 = 90

x + 67 = 90

Subtract both sides 67

x = 23

6. Adds up to 90° since its complementary

43 + x - 7 = 90

x + 36 = 90

Subtract both sides by 36

x = 54

7. Adds up to 180° since its supplementary

29 + x - 5 = 180

x + 24 = 180

Subtract both sides by 24

x = 156

8. Adds up to 180° since its supplementary

110 + 7x = 180

Subtract both sides by 110

7x = 70

Divide both sides by 7

x = 10

9. Adds up to 180° since its supplementary

72 + x + 4 = 180

x + 76 = 180

Subtract both sides by 76

x = 104

10. Adds up to 90° since its complementary

49 + x + 3 = 90

x + 52 = 90

Subtract both sides by 52

x = 38

11. Adds up to 180° since its supplementary

92 + x + 78 = 180

x + 170 = 180

Subtract both sides by 170

x = 10

12. Adds up to 180° since its supplementary

19 + x - 50 = 180

x - 31 = 180

Add 31 to both sides

x = 211

13. Supplementary angles add up to 180°

∠C + ∠D = 180

∠C + 45 = 180

Subtract both sides by 45

∠C = 135°

Imagine cutting this shape into two semi-circles and one rectangle.

------------------------------------------------------------------------------------------------------

--------------------------------------------------------------------

We know the area of a whole circle which is π[tex]r^{2}[/tex]

because a semi-circle is basically half of the whole circle!

However, since we have two equal semi-circles...we can just put them together and solve for the whole circle's area.

for reference:

1/2(π[tex]r^{2}[/tex]) + 1/2(π[tex]r^{2}[/tex]) = 2/2(π[tex]r^{2}[/tex]) = π[tex]r^{2}[/tex]

----------------------------------------------------------

First, the area of rectangle: length times width = 84 x 36 = 3024 square meters

Anyways, since we have to sub in 3.14 for π

Area of a whole circle: (3.14 x [tex]r^{2}[/tex]) = (3.14 x [tex]18^{2}[/tex]) = 1017.36 square meters

-----------------------------------------------------------

3024 + 1017.36 = 4041.36 square meters

Answer:

12 years later.

Step-by-step explanation:

Let assume in X years, the table will be twice as old as the sofa.

36+X=2(12+X), X=12

Or think it the other way. The difference of ages between two things never change. So they must have a difference(of age) of 24 forever. When will this difference(24) be as same as the younger's age so that the older one is exactly twice as old as the younger? 12 years later when the sofa is 24.
