Nina [5.8K]

Answer:

I’m afraid I can’t help you. The question makes no sense because the question doesn’t explain how many students there are. It just gives the weight of the books which I assume is useless

What is the first step to take when solving this linear system of equations by the addition-subtraction method? 2x + 4y = 3 x +

Free_Kalibri [48]

The right answer is Option D.

Step-by-step explanation:

Given equations are;

2x+4y=3 Eqn 1

x+3y=13 Eqn 2

When we use subtraction-addition method, we make one of the variables same with opposite signs so that only one variable remains after addition or subtraction.

In the given problem, we will multiply Eqn 2 with "-2" so that the x variables become equal and then we can add both the equations and solve for y.

Therefore,

The first step will be to multiply the second equation by -2 to solve the linear system of equations.

The right answer is Option D.

Solve the equation below using a graphing

UNO [17]

Answer:

Step-by-step explanation:

The given equation is:

$e^x-\ln 2x = 3.7$

Moving all terms to the left side:

$e^x-\ln 2x - 3.7=0$

Now we define a function:

$y=f(x)=e^x-\ln 2x - 3.7$

The solutions of the equation are the values of x such that y=0.

Since the function cannot be solved by algebraic methods, we use a graphing tool.

Those points where the graph crosses the x-axis are solutions of the equation.

Please refer to the graph in the figure below.

We can clearly identify there are two solutions at

x = 0.05

x = 1.57

After losing 22 lb in each of the first two

Pavel [41]

Answer:

Weight on 1 may = 104 lb

Step-by-step explanation:

Given:

Weight on last may = 110 lb

Weight gain for to week = 2 x 19 = 38 lb

Weight lose for to week = 2 x 22 = 44 lb

Find:

Weight on 1 may

Computation:

Weight on 1 may = Weight on last may - Weight gain for to week + Weight lose for to week

Weight on 1 may = 110 - 44 + 38

Weight on 1 may = 104 lb
