Please help!! 10-15 much appreciated! :)

Answer:

(8, -5); x=8; y=-5

Step-by-step explanation:

i'll be solving via substitution

2x+3y=1; y=-2x+11

2x + 3(-2x +11) = 1

2x -6x +33 = 1

-4x = -32

x = 8

2(8) + 3y = 1

16 + 3y = 1

3y = -15

y = -5

(8, -5)

Check:

-5 = -2(8) + 11

-5 = -16 + 11

-5 = -5

Answer:

− 108 x 5 y 7

Step-by-step explanation:

My computer wont allow it but the 5 and the 7 are exponents

Answer:

[tex]-108x^{5}y^{7}[/tex]

Step-by-step explanation:

Simplify using the laws of exponents (there are more rules than listed, these given rules are just the ones that come into play here);

- when there is a term in parenthesis with an exponent outside, the term's exponent gets multiplied by the exponent outside

- when multiplying two exponents, one can only combine terms with the same base, and one must add the exponents

[tex](3xy^{2})^{3}*(-4x^{3}y)\\\\=(3^{3}*x^{3}*y^{2{^{3}}}) *(-4x^{2}y)\\\\=(27x^{3}y^{6})(-4x^{2}y)\\\\=-108x^{5}y^{7}[/tex]

Step-by-step explanation:

What variable are you solving for?

Answer: b=75

Step-by-step explanation: Given that the health club charges $30 per month, we know that this is the "m" varible. We know this because the total value changes as the value of x changes. The value of b would therefore be $75 dollars because it is a constant and a one time fee. The person joining the health club pays an amount of money per month, as well as an initial charge of $75.

Answer:

4x + 17

Step-by-step explanation:

9 - 2x + 8+ x + 5x

Add/Subtract the values with variables together and the same case for the values without any variables.

5x + x - 2x = 4x

9 + 8 = 17

So you'll end up with the following,

4x + 17

Answer:

13.52 fluid ounces should be the right answer! :)

Step-by-step explanation:

Andre drank from the bottle 13.52 fluid ounces if he drank 80% of bottle.

Percentage is defined as the parts of a number in a whole of 100. This is denoted by the symbol '%'.

In other words, percentage can be defined as the ratio expressed as a fraction of 100.

Any number can be expressed as a percentage of another number by dividing the number with the whole of other number and then multiplying with 100.

Given that, fluid contained in a sports bottle = 16.9 fluid ounces.

Andre drank 80% of the fluid contained in the bottle.

80% of the bottle = 80% × 16.9

                             = (80 / 100) × 16.9

                             = 0.8 × 16.9

                             = 13.52

So this is the total fluid ounces Andre drink.

Hence Andre drank 13.52 fluid ounces from the bottle.

Answer:

1.5

Step-by-step explanation:

Answer:

a = 8, b = [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

Given the exponential function

f(x) = a[tex]b^{x}[/tex]

To find a and b use the given coordinate points on the graph

Using (0, 8 ), then

8 = a[tex]b^{0}[/tex] [ [tex]b^{0}[/tex] = 1 ] , then

a = 8

f(x) = 8[tex]b^{x}[/tex]

Using (2, 18 ) , then

18 = 8b² ( divide both sides by 8 )

[tex]\frac{18}{8}[/tex] = b² , that is

b² = [tex]\frac{9}{4}[/tex] ( take the square root of both sides )

b = [tex]\sqrt{\frac{9}{4} }[/tex] = [tex]\frac{3}{2}[/tex]

Thus

f(x) = 8[tex](\frac{3}{2}) ^{x}[/tex]

Step-by-step explanation:

Answer:  P(Quarter & Penny):  9/100

p(Two pennies): 9/25

Step-by-step explanation:

There are 20 coins in the bag, so you have a 3/20 chance of getting a quarter, 5/20 chances of getting a dime and 12/20 chance of getting a penny on each draw if the coins are always replaced.

Im this situation, you can simplify the fractions, the

Multiply the chance of each independent event times the chance of the next independent event.

3/20 × 3/5 = 9/100 for the quarter and the penny

3/5 × 3/5 = 9/25  for the two pennies

Solution: The commutative property of addition states that when two numbers are being added, their order can be changed without affecting the sum.

Answer:

4.25 m

Step-by-step explanation:

Resolvemos esta pregunta usando la fórmula:

Altura del hombre / Sombra de un hombre = Altura del palo / Sombra del palo

Sombra del hombre = 3.50 m

Altura de un hombre = 1.75 m

Sombra del palo = 8.50 m

Altura del palo = x

Por lo tanto:

1.75 / 3.5 = x / 8.5

Cruz multiplicar

1.75 × 8.5 = 3.5 × x

14.875 = 3.5x

x = 14.875 / 3.5

x = 4.25 metros

Por tanto, la altura del palo = 4.25 m

Given:

The graph of a proportional relationship contains the point (8,4).

To find:

The corresponding equation.

Solution:

If y in directly proportional to x, then

[tex]y\propto x[/tex]

[tex]y=kx[/tex]        ...(i)

Where, k is the constant of proportionality.

The graph of a proportional relationship contains the point (8,4).

Putting x=8 and y=4 in (i), we get

[tex]4=k(8)[/tex]

[tex]\dfrac{4}{8}=k[/tex]

[tex]\dfrac{1}{2}=k[/tex]

Putting [tex]k=\dfrac{1}{2}[/tex] in (i), we get

[tex]y=\dfrac{1}{2}x[/tex]

Therefore, the required equation is [tex]y=\dfrac{1}{2}x[/tex].

Answer:

Light is about 299,999,700 mps (meters per second) faster than sound in dry air.

Step-by-step explanation:

We know that the speed of light is about 3 × 10 ^ 8 meters per second and that the speed of sound in dry air is about 3 × 10 ^ 2 meters per second. We need to solve 3 × 10 ^ 8 minus 3 × 10 ^ 2.

3 × 10 ^ 8 - 3 × 10 ^ 2 =

300,000,000 - 300 = 299,999,700

Light is about 299,999,700 mps (meters per second) faster than sound in dry air.
