PLEASE HELP ASSAP LIKE NOW Graph the system of equations on graph paper to answer the question.

Mathematics
1 answer:
7nadin3 [17]3 years ago
3 0

Answer:

<em>(-3, -1)</em>

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
dlinn [17]

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.
