The function Jammie graphed is $x^2-5x+6=0$

Step-by-step explanation:

The zeros of quadratic function are at x=2 and x=3

We can write them as:

$x-2=0\,\,and\,\,x-3=0\\or\\(x-2)(x-3)=0$

Multiplying them

$(x-2)(x-3)=0\\x(x-3)-2(x-3)=0\\x^2-3x-2x+6=0\\x^2-5x+6=0$

So, The function Jammie graphed is $x^2-5x+6=0$

Answer:

Therefore, the length of hypotenuse is: 13 units

Step-by-step explanation:

As the given triangle is a right triangle.

We can find the length of hypotenuse using the Pythagoras' Theorem

Let c be the length of hypotenuse

Using Pythagoras' Theorem for the given triangle

$5^2\:+\:12^2\:=\:c^2$

$\mathrm{Switch\:sides}$

$c^2=5^2+12^2$

$c^2=25+144$

$c^2=169$

$\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}$

$c=\sqrt{169},\:c=-\sqrt{169}$

$c=13,\:c=-13$

As the length of hypotenuse cannot be negative. Therefore, the length of hypotenuse is: 13 units

Given that 3x + y = 0 and 2x - y = 5, find the value of y.

professor190 [17]

Answer:

3x + y = 0

x = -y/3

Now, 

2x - y = 5

2 (-y/3) - y = 5

(-2y - 3y)/3 = 5

-5y/3 =5

y=-3

The equilateral triangles shown below are similar.

Drupady [299]

Answer:

Below in bold.

Step-by-step explanation:

The smaller one has side 2 and the corresponding side on the larger one is 5, so the answer is 2/5.

The individual sides and perimeter are one-dimensional, so:

The ratio of their perimeters is the same 2/5.

The ratio of their areas ( which is 2 dimensional) is 2^2/5^2 = 4/25.
