What is the distance between a line that has endpoints at (1,5) and (1,-5)?

Since the x values (1) and (1) are the same, we just have to worry about the (5) and (-5)

the distance between a (5) and (-5)
would be (5) - (-5)
which is equal to (5) + (5) = 10

therefore your answer would be C. 10

note that distance should always be a positive number

Use completing the square to find the value to add that makes x^2 - 12x a perfect square trinomial. Then write the expression as

yarga [219]

Answer:

Step-by-step explanation:

If you want to make

$x^2-12x$

into a perfect square binomial, take half the linear term, square it, then add it to both sides. Our linear term is 12. Half of 12 is 6, and 6 squared is 36.

The value that makes this a perfect square binomial is 36.

Writing the expression as a square of the binomial is:

$(x^2-12x+36)-->(x-6)^2$

It is possible to get 2 solutions when the system of equations is: (check all that apply)

SVETLANKA909090 [29]

Answer:

A system of the equation of a circle and a linear equation

A system of the equation of a parabola and a linear equation

Step-by-step explanation:

Let us verify our answer

A system of the equation of a circle and a linear equation

Let an equation of a circle as $x^2+ y^2 = 1$ ..........(1)

Let a liner equation Y = x ............(2)

substitute (2) in (1)

$x^2 + x^2 = 1\\2x^2 = 1\\$

$x^2 = \frac{1}{\sqrt{2} } \\x = +\frac{1}{\sqrt{2} } , -\frac{1}{\sqrt{2} }$ so Y = $+\frac{1}{\sqrt{2} } , -\frac{1}{\sqrt{2} }$

so the two solution are ( $(\frac{1}{\sqrt{2} } ,\frac{1}{\sqrt{2} }) (-\frac{1}{\sqrt{2} }, -\frac{1}{\sqrt{2} }$ )

A system of the equation of a parabola and a linear equation

Let equation of Parabola be $y^2 = x$

and linear equation y = x

substitute

$x^2 = x\\x^2 - x= 0\\x(x-1) = \\x = 0 , 1$

Y = 0,1

so the two solutions will be (0,0) and (1,1)

70% is equal to 175$ dollars how many dollars are in 100%

zheka24 [161]

100% = $250

divide $175 by 70 to obtain 1% then multiply by 100 for 100%

100% = $175 × $\frac{100}{70}$ = $250
