I will give brainliest to the correct answer!

Answer:

One thing that is unclear here is whether the "1." at the start is part of the number "1.2" or if it is an enumeration of the question, and the base raised to the exponent is in fact 2.

The rest of the equation seems to indicate the latter, so we'll solve both:

If 1.2ᵃ ₓ 2⁵ = 2⁰, then a is approximately equal to -19.009.

If as I'm guessing is the correct question, 2ᵃ ₓ 2⁵ = 2⁰, then a is equal to -5.

Step-by-step explanation:

Interpretation #1:

[tex]1.2^a \times 2^5 = 2^0\\1.2^a \times 32 = 1\\1.2^a = \frac{1}{32}\\log_{1.2} \frac{1}{32} = a\\a \approx -19.009[/tex]

Interpretation #2:

Here the question is much simpler, as we need only add the exponents when adding and dividing:

[tex]2^a \times 2^5 = 2^0\\2^a = 2^0 \div2^5\\2^a = 2^{-5}\\a = -5[/tex]

Answer:

44

Step-by-step explanation:

Number who use balls only = 7 / 20

Number who use rings only = 3/7

Fraction who use both :

1 - (7/20 + 3/7)

1 - 0.7785714

= 0.2214285

If number of jugglers is less than 200

Number of jugglers who use both :

0.2214285 * 200

= 44.285714

Number of jugglers who use both should be about 44

Answer:

x=-3

Step-by-step explanation:

2(-2x-8) + 4x = 2(1+3x)

Distribute:

-4x-16+4x=2+6x

Simplify Like-Terms:

-16=2+6x

Subtract 2 from both sides:

-18=6x

Divide both sides by 6:

x=-3

Answer:

3/4 and 0.95 would both result in a reduction.

Step-by-step explanation:

multiplying by anything less than 1 will make it smaller which both 3/4 and 0.95 are smaller than 1.

Hey again!

The answers to your question are 3/4 and 0.95

A reduction is making it smaller, and since 3/4 and 0.95 are smaller than 1, they result in a reduction

Hope it helps! Also, how many questions do you have left?

Answer:

-6x

Step-by-step explanation:

23x+50x-79x

We take out x from the terms and group them up.

We therefore get (23+50-79)x after taking out x, and grouping the coefficients together.

Calculating 23+50-79 gets us -6, which is the coefficient of the final answer.

So the answer would be -6x.

Answer:

Step-by-step explanation:

Here you go mate,

Step 1

23x+50x-79x  Equation/Question

Step 2

23x+50x-79x  Simplify

23x+50x-79x

Step 3

23x+50x-79x  Combine terms

(23x+50x+(-79x))

Step 4

(23x+50x+(-79x))  Solve

answer

-6x

Hope it helps

Answer:

Given the reference to the chain rule, I assuming by "calculate", you mean "take the derivative of", in which case we have:

For the first function:

[tex]y = (2u^2 + 3)^{\frac{1}{3}}\\\\\frac{dy}{du} = \frac{1}{3}(2u^2 + 3)^\frac{-2}{3}(4u)\\\\\frac{dy}{du} = \frac{4u}{3}(2u^2 + 3)^\frac{-2}{3}\\\\\frac{dy}{du} = \frac{4u}{3(2u^2 + 3)^\frac{2}{3}}[/tex]

and for the second one:

[tex]u = \sqrt{2x + 1}\\\\u = (2x + 1)^{0.5}\\\\\frac{du}{dx} = 0.5(2x + 1)^{-0.5}(2)\\\\\frac{du}{dx} = \frac{1}{\sqrt{2x + 1}}[/tex]

Answer: x = 4 and y = -3

Step-by-step explanation:

2x + 4y = -4

2x = -4 - 4y

x = -2 - 2y

Now that we have solved the first equation for x, we plug (-2 - 2y) into the other equation in place of x and then solve for y.

3(-2 -2y) + 5y = -3

-6 - 6y + 5y = -3

-y = 3

y = -3

Now that we know y, we plug it into the original equation and solve for x.

2x + 4(-3) = -4

2x + -12 = -4

2x = 8

x = 4

You can check the answer by plugging both x and y into either of the original equations.

Answer:

The system of linear inequalities to model the situation is written as:

x + y ≥ 5..... Equation 1

4x + 10y ≤ 100..... Equation 2

Step-by-step explanation:

Let

The number is soil = x

The number of plants = y

You are buying plants and soil for your garden.

You want to buy at least 5 plants

At least = greater than or equal to with the inequality sign(≥)

Hence:

x + y ≥ 5..... Equation 1

The soil cost $4 per bag and the plants cost $10 each and can spend no more than $100.

No more than means Less than or equal to with the inequality sign( ≤ )

Hence:

$4 × x +$10 × y ≤ $100

= 4x + 10y ≤ 100..... Equation 2

Therefore, the system of linear inequalities to model the situation is written as:

x + y ≥ 5..... Equation 1

4x + 10y ≤ 100..... Equation 2

Answer:

The value of the larger number is

[tex]x=24[/tex]

Step-by-step explanation:

A number, x, is 4 times another number, y.

[tex]x=4y[/tex] --------- (1)

The difference between the two numbers is 18.

[tex]x-y=18[/tex] -------(2)

Re-arranging equation (2) yields

[tex]-y=18-x\\y=x-18[/tex]------------- (3)

Substitute y=x-18 in equation (1)

[tex]x=4 (x-18)[/tex]

[tex]x=4x-72\\x-4x=-72[/tex]

[tex]-3x=-72\\x=\frac{72}{3}\\x=24[/tex]

Substitute x=24 in equation (3)

[tex]y=24-18\\y=6[/tex]
