5y-14=2y-2 solve for y and show work plz
MrMuchimi

Answer:

y=4

Step-by-step explanation:

Let's solve your equation step-by-step.

5y−14=2y−2

Step 1: Subtract 2y from both sides.

5y−14−2y=2y−2−2y

3y−14=−2

Step 2: Add 14 to both sides.

3y−14+14=−2+14

3y=12

Step 3: Divide both sides by 3.

3y/3=12/3

y=4

The owner of a motel has 2900 m of fencing and wants to enclose a rectangular plot of land that borders a straight highway. If s
navik [9.2K]

Answer:

Step-by-step explanation:

Given that the owner of a motel has 2900 m of fencing and wants to enclose a rectangular plot of land that borders a straight highway.

Fencing is used for 2times length and 1 width if highway side is taken as width

So we have 2l+w = 2900

Or w = 2900-2l

Area of the rectangular region = lw

A(l) = l(2900-2l) = 2900l-2l^2\\

Use derivative test to find the maximum

A'(l) = 2900-4l\\A"(l) = -4

So maximum when I derivative =0

i.e when l =\frac{2900}{4} =725

Largest area = A(725)

= 725(2900-2*725)\\= 1051250

1051250 sqm is area maximum

Indicate whether the statement is true of false.
yawa3891 [41]

The statement is false, as the system can have no solutions or infinite solutions.

<h3>Is the statement true or false?</h3>

The statement says that a system of linear equations with 3 variables and 3 equations has one solution.

If the variables are x, y, and z, then the system can be written as:

a_1*x + b_1*y + c_1*z = d_1\\\\a_2*x + b_2*y + c_2*z = d_2\\\\a_3*x + b_3*y + c_3*z = d_3

Now, the statement is clearly false. Suppose that we have:

a_1 = a_2 = a_3\\b_1 = b_2 = b_3\\c_1 = c_2 = c_3\\\\d_1 \neq d_2 \neq  d_3

Then we have 3 parallel equations. Parallel equations never do intercept, then this system has no solutions.

Then there are systems of 3 variables with 3 equations where there are no solutions, so the statement is false.
