X = -3/14
I just did it on a calculator:)

Answer:

x = -3/14

Step-by-step explanation:

1/2(2x-1) = -1/7 -4/7

Combine like terms

1/2(2x-1) = -5/7

Multiply each side by 2

2*1/2(2x-1) = -5/7*2

2x-1 = -10/7

Add 1 to each side

2x-1+1 = -10/7 +1

2x = -10/7 +7/7

2x = -3/7

Divide by 2

2x/2 = -3/7 *1/2

x = -3/14

Y = – 3
KonstantinChe [14]

The  best approximation for the solution to this system of equations is (-2.2,-3)

Option C is correct.

Step-by-step explanation:

Solving the system of equations to get the exact value of x:

y = -3\\y = x-0.8

Let

y = -3\,\,eq(1)\\y = x-0.8\,\,eq(2)

Putting value of y from eq(1) into eq(2)

-3=x-0.8

x=-3+0.8

x=-2.2

So, Value of x is -2.2

The  best approximation for the solution to this system of equations is:

x=-2.2 and y = -3

(-2.2,-3)

Option C is correct.

The angles of elevation froma point X to the top of flagpoles A and B are 35* and 45* respectively. If X lies in the middle of t
BartSMP [9]

Let AB = t. And since X lies in the middle, so AX=BX = t/2 .

Let the height of the smaller flagpole is AO and of larger flagpole is BP .

Using tangent ratio rule in each triangle, we will get

tan 35 =\frac{AO}{t/2} , tan 45= \frac{BP}{t/2} // AO = \frac{t*tan35}{2},  BP=\frac{t*tan45}{2}

And there ratio is

\frac{AO}{BP}= \frac{tan 35}{tan 45}=\frac{0.7}{1}
