Answer:

\huge\boxed{t=3}

Step-by-step explanation:

-5(t+3)=-30

<h3>METHOD 1:</h3>

-5(t+3)=-30    <em>divide both sides by (-5)</em>

<em />\dfrac{-5\!\!\!\!\diagup(t+3)}{-5\!\!\!\!\diagup}=\dfrac{-30}{-5}<em />

<em />t+3=6<em>       subtract 3 from both sides</em>

t+3-3=6-3\\t=3

<h3>METHOD 2:</h3>

-5(t+3)=-30       <em>use the distributive property </em><em>a(b + c) = ab + ac</em>

<em />(-5)(t)+(-5)(3)=-30<em />

<em />-5t-15=-30<em>     </em><em>add 15 to both sides</em>

<em />-5t-15+15=-30+15<em />

<em />-5t=-15<em>         divide both sides by (-5)</em>

\dfrac{-5t}{-5}=\dfrac{-15}{-5}\\\\t=3

Each number in the code can be 1 of 10 numbers.


The total number of possible combinations is 10 * 10 * 10 * 10 = 10,000

The probability of getting 1234 would be 1/10,000

The equation x 2y = 16 is in standard form. what is the slope of the line? â€""2 â€""1 â€""0.5 0.5
Savatey [412]

By rewriting the given line, we can see that the slope is equal to -1/2 or -0.5

<h3>How to get the slope of the given line?</h3>

Remember that a line is:

y = a*x + b

Where a is the slope and b is the y-intercept of the line, which is the point where the line intersects the y-axis.

Then, we can rewrite our equation:

x + 2y = 16

to:

2y = 16 - x

y = (16 - x)/2

y = (-1/2)*x + 8

Comparing with the general line equation, we can see that the slope is -1/2.

Which exponential functions have been simplified correctly check all that apply
Fittoniya [83]
Principle: Law of Exponents - Combination of product to a power & power to a power. The first is when raising a product of two integers to a power, the power is distributed to each factor. In equation it is,

(xy)^a = (x^a)(y^a)

The latter is when raising the base with a power to a power, the base will remain the same and the powers will be multiplied. In equation it is, 
(x^a)(x^b) = x^ab

Check:


f(x) = 5*(16)^.33x = 5*(8*2)^0.33x = 5*(8^0.33x)(2^0.33x) = 5*(2^x)*(2^0.33x) = 5*(2^1.33x)

f(x) = 2.3*(8^0.5x) = 2.3*(4*2)^0.5x = 2.3*(2^x)(2^0.5x) = 2.3*(2^1.5x)

f(x) = 81^0.25x = 3^x

f(x) = 0.75*(9*3)^0.5x = 0.75*(3^x)*(3^0.5x) = 0.75*3^1.5x

f(x) = 24^0.33x = (8*3)^0.33x = (2^x)*(3^0.33x)


Therefore, the answer is third equation.

<em>ANSWER: f(x) = 81^0.25x = 3^x</em>

Catron evaluates the expression (negative 9) (2 and two-fifths) using the steps below.
Vlad [161]

Answer:

Catron's error is

"She did not follow order of operations"

Step-by-step explanation:

Catron evaluates the expression (negative 9) (2 and two-fifths)

That expression can be written as below

(-9)(2\frac{2}{5})

Catron's error is

"She did not follow order of operations"

The corrected steps are

Step1: Given expression is (-9)(2\frac{2}{5})

Step2: Convert mixed fraction into improper fraction

(-9)(2\frac{2}{5})=(-9)(\frac{12}{5})

Step3: Multiplying the terms

(-9)(2\frac{2}{5})=-7\frac{-108}{5}

Therefore solution (-9)(2\frac{2}{5})=-7\frac{-108}{5}
