Point A, located at (3, -8), is translated left 5 units. What are the coordinates of A'?

lukranit [14]

The answer would be (-2, -8) The eight wouldn't move, because if you are moving it left, it would only affect the X axis. Hope this helps!

What is the solution of StartRoot x squared + 49 EndRoot = x + 5?

Natasha2012 [34]

$x=\frac{12}{5}$ or x= twelve-fifths

Option A is correct.

Step-by-step explanation:

We need to find the solution of:

$\sqrt{x^2+49}=x+5$

Solving:

Taking square on both sides:

$(\sqrt{x^2+49})^2=(x+5)^2\\x^2+49=x^2+2(x)(5)+25\\Simplifying:\\x^2+49-x^2-10x-25=0\\-10x+24=0\\-10x=-24\\x=\frac{-24}{-10}\\ x=\frac{24}{10}\\x=\frac{12}{5}$

Verifying the solution by putting x = 12/5 in the given equation, we get true result.

So, $x=\frac{12}{5}$ or x= twelve-fifths

Option A is correct.

Ay/x=cz? variable is y.

babymother [125]

Ay/x = cz

Multiply 'x' to both sides:

Ay = czx

Divide 'A' to both sides:

y = (czx)/(A)
