The length of the rectangle is 2x + 8 cm and the width is 2cm . The area of the rectangle is 12 cm​

Answer:

35

Step-by-step explanation:

x + 10 = 45

x = 35

Answer:

x=35

Step-by-step explanation:

Opposite sides are equal so angle MNL is equal to JNK.

THerefore, JNK is 45 degrees.

So, x+10=45. We can simplify this to x=35.

Answer:

f(g(x)) = 2(7 - x) + 1

Step-by-step explanation:

f(x) = 2x + 1

g(x) = 7 - x

The question in the picture itself says to find f(g(x)) so i'll find that instead

f(g(x)) = 2(7 - x) + 1

f(g(x)) = 14 - 2x + 1

f(g(x)) = -2x + 15

Answer:

Value of x is used to consider unknown value. The letter “x” is commonly used in algebra to indicate an unknown value. It is referred to as a “variable” or, in some cases, a “unknown.” In x + 2 = 7, x is a variable. ... A variable need not be “x,” but might be “y,” "w," or any other letter, name, or symbol.

Answer:

y = - x + 4

Step-by-step explanation:

First find slope:

6-1/-2-3 = 5/-5 = -1

Then plug one point and slope into point slope form: y-y1 = k (x-x1)

Plug in (3, 1) and slope -1 --> y-1 = -1(x-3)

Simplify --> y - 1 = - x + 4

Then add 1 to both sides --> y = -x + 4

Answer:

10 weeks

Step-by-step explanation:

Initial weight: 40

1 week =  0.2 lbs lost

40 - 38 = 2 lbs lost (goal)

x = number of weeks

0.2*x = 2

0.2x = 2

Answer:

(7, 6 )

Step-by-step explanation:

2x + y = 20 ( subtract 2x from both sides )

y = 20 - 2x → (1)

- 5y = - 6x + 12 → (2)

Substitute y = 20 - 2x into (2)

- 5(20 - 2x) = - 6x + 12 ← distribute parenthesis on left side

- 100 + 10x = - 6x + 12 ( add 6x to both sides )

- 100 + 16x = 12 ( add 100 to both sides )

16x = 112 ( divide both sides by 16 )

x = 7

Substitute x = 7 into (1)

y = 20 - 2(7) = 20 - 14 = 6

solution is (7, 6 )

Answer:

length = 100m

perimeter = 300m

Step-by-step explanation:

area=l×w

area=l×50

area=50l

5000=50l

l=100

perimeter =2(l+w)

perimeter=2(100+50)

perimeter =300m

Answer:

x=2

Step-by-step explanation:

To solve for x, you want to isolate it. To do this, move terms that are NOT x and use the opposite operation to get it to the other side.

10x - 3 = 17

(Add 3 to both sides)

10x = 20

Now isolate x (since 10x is really 10 * x, you divide)

10x=20

x=2

This is how you would solve to get the solution.

Hope this helps :D

Answer:

Step-by-step explanation:

g(x) = ax - b

-76 = 27a - b

-79 = 28a - b           Subtract

3 = -a                       Multiply both sides by  -1

a = -3

g(x) = -3x - b

-85 = -3*30 - b

-85 = - 90 - b          Add 90 to both sides

90-85 = - b             Combine

5 = - b                     Multiply both sides by - 1

-5 = b

g(x) = -3x - b

g(x) = -3x - (-5)

g(x) = - 3x + 5

The system of inequalities represent these constraints is 24x + 6y > 200 and 16x + 5.40y ≤ 160

Inequalities shows the non equal comparison of numbers or expressions.

Let x represent the number of packages of 24 notepads and y represent the number of packages of 6 notepads

Since the organizers need to do at least 200 notepads, hence:

24x + 6y > 200

Also, they have a budget of $160. Let us assume that each 24 package cost $16 and each 6 package cost $5.40, hence:

16x + 5.40y ≤ 160

The system of inequalities represent these constraints is 24x + 6y > 200 and 16x + 5.40y ≤ 160

Answer:

Mixed Number: 5 [tex]\frac{7}{10}[/tex]

Improper Fraction:[tex]\frac{57}{10}[/tex]

Step-by-step explanation:

A mixed number is when you express the decimal as a fraction, 0.7 is the same as [tex]\frac{7}{10}[/tex], so 5[tex]\frac{7}{10}[/tex] is your answer.

An improper fraction is a fraction where the numerator is bigger than the denominator, to do this you multipy the whole number 5, which can be written as [tex]\frac{5}{1}[/tex], by [tex]\frac{10}{10}[/tex].

[tex]\frac{5}{1}[/tex]·[tex]\frac{10}{10}[/tex]=[tex]\frac{50}{10}[/tex]

Then add 0.7, or [tex]\frac{7}{10}[/tex].

[tex]\frac{50}{10}[/tex]+[tex]\frac{7}{10}[/tex]=[tex]\frac{57}{10}[/tex]

An exponential function is a function that increases rapidly as the time increases.

Reasons:

The function that gives the height of a beanstalk is presented as follows;

b(t) = [tex]3^t[/tex]

When the height is 30,000 ft., we have;

30,000 = [tex]3^t[/tex]

㏑(30,000) = t·㏑(3)

[tex]\displaystyle t = \mathbf{\frac{ln(30,000)}{ln(3)}} \approx 9.384[/tex]

The time it would take the beanstalk to grow 30,000 ft., t ≈ 9.384 hours

Similarly, the time it would take the beanstalk to grow to 36,000 ft. is found as follows;

[tex]\displaystyle t_{36,000} = \mathbf{\frac{ln(36,000)}{ln(3)}} \approx 9.55[/tex]

The time it would take the beanstalk to grow 36,000 ft., t ≈ 9.55 hours

The number of hours it will take the beanstalk to grow to 30,000 feet at
