Answer fast pleaseeee :)

<u>Answer:</u>

The correct answer option is 'both Adler and Erika solved for <em>k</em> correctly because either the addition property of equality or the subtraction property of equality can be used to solve for <em>k</em><em>'.</em>

<u>Step-by-step explanation:</u>

Both Adler and Erika have solved for <em>k</em> correctly since both the properties, addition property of equality and subtraction property of equality, can be to solve for <em>k.</em>

The fraction \frac{1}{2} has to be subtracted from both the sides so even if it is added, the negative sign still would make it subtracted from both the sides.

Prove that there are no solutions in integers x and y to the equation 2x^2 + 5y^2 = 14
iren [92.7K]
Solve the equation for y using the formula for slope: y + mx + b

2x^2 + 5y^2 = 14
5y^2 = -2x^2 + 14
y^2 = -2/5x^2 + 14/5
y = the sq root of -2x^2/5 + 14/5

There is no integer solution to the square root of a negative number.

A service station will be built on the highway, and a road will connect it with cray. How long will the new road be?
zysi [14]

Answer: 4.6 mi

Step-by-step explanation:

Suppose the points A, B, C and S shows Alba, Blare, Cray and Service station respectively,

Then, We have to find out the line segment CS = x = ?

Now, In the triangles ACB and CSB,

\angle ACB\cong \angle CSB     ( Right angles )

\angle ABC\cong \angle CBS      ( Reflexive angles )

Thus, by AA similarity postulate,

\triangle ACB\sim\triangle CSB

By the property of similar triangles,

\frac{AB}{CB}=\frac{AC}{CS}

\implies \frac{13}{5}=\frac{12}{x}

\implies 13x=5\times 12

\implies 13x = 60

\implies x =\frac{60}{13}=4.61539\approx 4.6

Hence, the approximate length of the new road = 4.6 miles
