What is the answer for the equation 8(2x+9)=56

Answer:

AC = 52.8

Step-by-step explanation:

33/20 = 1.65

12*1.65 = 19.8

BA = 19.8

CB + BA = AC

33 + 19.8 = 52.8

Answer:

AC = 52.8

Step-by-step explanation:

Since BE is parallel to CD and intersects the 2 sides of the triangle then it divides those sides proportionally, that is

[tex]\frac{BC}{AB}[/tex] = [tex]\frac{DE}{AE}[/tex], substituting values

[tex]\frac{33}{AB }[/tex] = [tex]\frac{20}{12}[/tex] ( cross-  multiply )

20AB = 396 ( divide both sides by 20 )

AB = 19.8

Thus

AC = AB + BC = 19.8 + 33 = 52.8

Answer:

Hence (3, -3)   is  on the given line y = -2x + 3

Step-by-step explanation:

For a point on the Line, It must Satisfy the Equation of a line

Therefore for

[tex]y=-2x+3[/tex]

For (-2,-1)

Substitute x = - 2 and y = -1 in above equation

Left Hand Side = y

                         = -1

Right Hand Side = -2 × (-2) +3

                           = 4 +3

                           = 7

Left Hand Side ≠ Right Hand Side

Not Satisfied

Hence (-2,-1)  is NOT on the given line

For (3, -3)

Substitute x = 3 and y = -3 in above equation

Left Hand Side = y

                         = -3

Right Hand Side = -2 × (3) +3

                           = -6 +3

                           = -3

Left Hand Side = Right Hand Side

Satisfied

Hence (3, -3)   is  on the given line y = -2x + 3

For (3, 3)

Substitute x = 3 and y = 3 in above equation

Left Hand Side = y

                         = 3

Right Hand Side = -2 × (3) +3

                           = -6 +3

                           = -3

Left Hand Side ≠ Right Hand Side

Not Satisfied

Hence (3,3)  is NOT on the given line

For (-3,-9)

Substitute x = -3 and y = -9 in above equation

Left Hand Side = y

                         = -9

Right Hand Side = -2 × (-3) +3

                           = 6 +3

                           = 9

Left Hand Side ≠ Right Hand Side

Not Satisfied

Hence (-3,-9)  is NOT on the given line

Only the point (3, -3) lies on the line y = -2x + 3. None of the other points satisfy the equation.

To determine which point lies on the line y = -2x + 3, we need to substitute the coordinates of each point into the equation:

(-2, -1): Substitute x = -2 into y = -2x + 3:

y = -2(-2) + 3 = 4 + 3 = 7. Since y = -1, this point does not lie on the line.

(3, -3): Substitute x = 3 into y = -2x + 3:

y = -2(3) + 3 = -6 + 3 = -3. Since y = -3, this point lies on the line.

(3, 3): Substitute x = 3 into y = -2x + 3:

y = -2(3) + 3 = -6 + 3 = -3. Since y = 3, this point does not lie on the line.

(-3, -9): Substitute x = -3 into y = -2x + 3:

y = -2(-3) + 3 = 6 + 3 = 9. Since y = -9, this point does not lie on the line.

The only point that satisfies the equation is (3, -3).

Complete question:

Which point is on the line y = -2x + 3?

A. (-2,-1)

B. (3, -3)

C. (3, 3)

D. (-3,-9)

Answer:

∴ ∠BAD = [tex]sin^{-1}[/tex](0.2044) = 11.8°

Step-by-step explanation:

i) AD = 9 cm

ii) DC = 3 cm

iii) ∠BCD = 35°

iv) Since AB is parallel to DC and ∠ABD = 90°  then we can conclude that ∠BDC = 90°.

v) [tex]\frac{BD}{DC} = \frac{BD}{3\hspace{0.1cm}cm} = tan(35)[/tex] = 0.6128      ∴ BD  = 3 [tex]\times[/tex] 0.6128 = 1.84 cm

vi) ∴ sin(∠ BAD ) = [tex]\frac{BD}{AD}[/tex]      ⇒     sin(∠ BAD ) = [tex]\frac{1.84}{9}[/tex] = 0.2044

     ∴ ∠BAD = [tex]sin^{-1}[/tex](0.2044) = 11.8°

Answer: 6

Step-by-step explanation: 12/2 because a pair is 2 people and there are 12 people in total.!

The number of different pairs of people who can have conversations at a round table with 12 people is 66. This is calculated using the combination formula C(n, 2).

The student asks about the number of different pairs of people who can have conversations at a round table with 12 people, assuming that everyone can talk to each other. The problem is a combinatorial one and can be solved by using the formula for combinations. The formula for the number of combinations of pairs from a set of n items is [tex]C(n, 2) = \frac{n! }{2! * (n - 2)!}[/tex], where n! (n factorial) is the product of all positive integers up to n, and C denotes the combination.

To find how many different pairs can have conversations, we plug in n = 12 into the combination formula:

[tex]C(12, 2) = \frac{12! }{2! * (12 - 2)!} = \frac{12 * 11}{2 * 1} = 66[/tex]

So, there are 66 different pairs of people that can have conversations at a round table with 12 people.

Answer:

The functions which has the same horizontal asymptote y = -3 as given in the graph are,

f(x) = [tex]2^{x} - 3[/tex]  and

f(x) = [tex]2^{(x+2)} -3[/tex]

Step-by-step explanation:

The function that is graphed has horizontal asymptote as y = -3 .

As x → -∞  f(x) → - 3  for the second and fourth function. Hence the functions which has the same horizontal asymptote y = -3 as given in the graph are,

f(x) = [tex]2^{x} - 3[/tex]  and

f(x) = [tex]2^{(x+2)} -3[/tex]

Answer:

(20 + n)¢

Step-by-step explanation:

With Company X, it costs 35¢ to connect  and then 5¢ for each minute.

So, for n minutes of calling the company X charges, C(x) = (35 + 5n)¢

Again,  With Company Y,  it costs 15¢ to connect and then 4¢ for each  minute.

So, for n minutes of calling the company Y charges, C(y) = (15 + 4n)¢.

Therefore, the company Y charges for n minutes of calling less than company X is [(35 + 5n) - (15 + 4n)]¢ = (20 + n)¢ (Answer)

To find how much more Company X charges than Company Y for n minutes, subtract the cost of Company Y from the cost of Company X. The expression to represent the difference in charges is 0.2 + 0.01n.

To find how much more Company X charges than Company Y, we need to subtract the cost of Company Y from the cost of Company X for n minutes.

Let's denote the cost of Company X as CX and the cost of Company Y as CY.

For Company X, the cost is $0.35 to connect and $0.05 for each minute. So, the cost of CX for n minutes is given by CX = 0.35 + 0.05n.

Similarly, for Company Y, the cost is $0.15 to connect and $0.04 for each minute. So, the cost of CY for n minutes is given by CY = 0.15 + 0.04n.

To find the difference in charges, we subtract CY from CX:

Company X charges (CX - CY) = (0.35 + 0.05n) - (0.15 + 0.04n) = 0.2 + 0.01n

If you are trying to find the equation of a line:

The equation of a line is y = mx + b   [m is the slope, b is the y-intercept or the y value when x = 0 --->  (0, y)  or the point where the line crosses through the y-axis]

Since you have m = -2, plug it into the equation

y = mx + b

y = -2x + b     To find b, plug in the point they gave you (3, -7)

-7 = -2(3) + b

-7 = -6 + b      Add 6 on both sides

-1 = b               Now that you have b, plug it into the equation

y = -2x - 1

Step-by-step explanation:

Cubic Root

The cubic root of a number N is M, if

[tex]M^3=N[/tex]

It's usually tedious to manually compute cubic roots, but if we use some basic algebra concepts, the job is easily done.

Let's compute

[tex]M=\sqrt[3]{0.000004913}[/tex]

The argument can be expressed in scientific notation as

[tex]0.000004913= 4913\ 10^{-9}[/tex]

The power of 10 has an exact cubic root since the exponent is a multiple of 3. To find the cubic root of the mantissa, we note it's the triple product of 17, i.e.

[tex]4913=17*17*17=17^3[/tex]

Thus our number is

[tex]M=\sqrt[3]{17^3\ 10^{-9}}=17\ 10^{-3}=0.017[/tex]

We have then

[tex]\boxed{\sqrt[3]{0.000004913}=0.017}[/tex]

By rounding each brother's weight to the nearest whole number and adding these, we get an estimate of 15 pounds. The actual total weight, 15 and one eighth pounds, is close to this estimate, indicating that Lucas' claim about his brothers' weight is reasonable. This demonstrates how estimation can be used to quickly verify the validity of a claim.

Estimation is a valuable mathematical tool that can be used to assess the reasonableness of a solution. In the case of Lucas' twin baby brothers' weight, you can use rounding to estimate their total weight. Let's start by rounding each brother's weight to the nearest whole number. In this scenario, Jackson, who weighs 6 and one fourth pounds could be estimated to weigh 6 pounds, and Jeremy, who weighs 8 and seven-eighths pounds, could be estimated to weigh roughly 9 pounds.

Adding these together gives a total of 15 pounds. The actual weight of the twins, 15 and one eighth pounds, is very close to this estimation, indicating that Lucas' claim about his brothers' weight is reasonable. This approach makes effective use of estimation as a means to quickly and simply verify a given claim's feasibility.
