Adiya said that the first step to solving the quadratic equation x2 + 6 = 20x by completing the square was to divide 6 by 2, squ

are that value, and add the result to both sides. Is Adiya’s solution method correct? Explain.

No, actually the method is not correct. Adiya needed to take x2 and subtract it from 20x. she would then get 6 = 18x. Have in mind also that she needed to divide 18. So 6 = 18x turns into 6=X. That is why is incorrect

Answer:

Adiya’s method is not correct. To form a perfect square trinomial, the constant must be isolated on one side of the equation. Also, the coefficient of the term with an exponent of 1 on the variable is used to find the constant in the perfect square trinomial. Adiya should first get the 20x term on the same side of the equation as x2. Then she would divide 20 by 2, square it, and add 100 to both sides.

What is the value of log 7 343?–3 -1/3 1/3 3
xeze [42]

Answer: 3

Step-by-step explanation:

Given :

Log_{7} 343

We need to write 343 in index form of 7.

343 is the same as 7^{3} , replacing 343 with 7^{3} , we have

Log_{7} 7^{3}

Recall one on the law of Logarithm :

Log_{a}b^{c} can be written as c Log_{a}b

So, Log_{7} 7^{3} can be written as ;

3Log_{7} 7

Also from the laws of Logarithms , Log_{a} a = 1

so , Log_{7}[/tex] 7 = 1

The solution then becomes

3 x 1 = 3

Therefore :

Log_{7} 343 = 3

What is the X-in intercept of the line 6x + y = 18
Keith_Richards [23]

\boxed{x=3}

Step-by-step explanation:

The Standard Form of the equation of line is given by:

Ax+Bx=C \\ \\ For \ A, \ B, \ C\ Real \ Constant \\ and \ A>0

So:

6x+y=18 \\ \\ is \ written \ in \ standard \ form

The x-intercept can be found setting y=0:

6x+(0)=18 \\ \\ Isolating \ x: \\ \\ 6x=18 \\ \\ \boxed{x=3}
