Answer:

Step-by-step explanation:

Given the system of equation

y=1/3x-2

y=-3x – 12

Since both equations are y values, we will equate then=m to each other as shown;

1/3x - 2 = -3x - 12

x/3 + 3x = -12 + 2

(x+9x)/3 = -10

x+9x = -30

10x = -30

x = -30/10

x = -3

Substitute x = 3 into equation 1;

From 1: y=1/3x-2

y=1/3(3)-2

y = 1 - 2

y = -1

<em>Hence the required solution (x, y) is (-3, -1)</em>

When Legs jumps 2 times and takes 13 steps forward, he lands in the same place as when he jumps 4 times and takes 5 steps backwa

tangare [24]

Answer:

9 steps

Step-by-step explanation:

Let $x$ be the number of jumps

and $y$ be the number of steps

So the first case

$2x+13y$

Second case

$4x-5y$

Both cover equal distances so

$2x+13y=4x-5y$

$\Rightarrow 2x-4x=-5y-13y$

$\Rightarrow 2x=18y$

$\Rightarrow x=9y$

So, one jumps is 9 steps.

Urgent help needed algebra 2

The missing values are shown in the attached picture, and 41 degrees F = 5 degrees C.

<h3>What is unit conversion?</h3>

It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.

We have:

$\rm F = \dfrac{9}{5}C + 32$

Make subject C and solve:

$\rm \dfrac{5}{9}(F-32) = \dfrac{5}{9}\times\dfrac{9}{5}C$

$\rm \dfrac{5}{9}(F-32) = C$

Plug F = 41

$\rm \dfrac{5}{9}(41-32) = C$

$\rm \dfrac{5}{9}(9) = C$

41 degrees F = 5 degrees C

Thus, the missing values are shown in the attached picture, and 41 degrees F = 5 degrees C.

A large open meadow near your city is shrinking in size because developers have started building new homes there.

valentinak56 [21]

Answer:

$t=-10\log 0.32$

Explanation:

<u>Equation:</u>

$A=1,562.5\times 10^{(-0.1t)}$

This is a decaying exponential function, because the exponent is negative.

Then, the larger the value of t (number of months), the smaller A (the number of hectares).

The factor 1,562.5 is the initial number of hecares, when t = 0.

You must find the value of t when A equals 500, thus solve the equation:

$500=1,562.5\times 10^{(-0.1t)$

Divide both sides by 1,562.5

$\dfrac{500}{1,562.5}=10^{(-0.1t)}$

$0.32=10^{(-0.1t)}$

Take base-10 logarithms on both sides:

$\log 0.32=-0.1t$

$t=-\dfrac{\log 0.32}{0.1}\\\\\\t=-10\log 0.32$

Note that the logarithm of a number decimal number is negative number, thus t will be positive. When you compute that, it is about 4.9 months.
