6 0

Answer:

2:3, 2 to 3

Step-by-step explanation:

9 and 6 are both factors of three, so you have to reduce. 3 goes into 9 tree times, and 3 goes into 6 twice. Since it is circles to squares, the 2 comes first then 3.

Find the value of f(-2)

ELEN [110]

$f(x)=\left\{\begin{array}{ccc}x^2&if\ x\leq1\\1&if\ 1 \ \textless \ x \leq2\\2-x&if\ 3 \ \textless \ x \leq6\end{array}\right\\\\f(-2)=?\\\\-2\leq1\ therefore\ f(x)=x^2\\\\subtitute\\\\f(-2)=(-2)^2=4$

Answer:

Step-by-step explanation:

Copy 1 is a scaled copy of the original triangle. The scale factor is 2, because each side in Copy 1 is twice as long as the corresponding side in the original triangle. , , Copy 2 is a scaled copy of the original triangle.

The measure of an angle is seventeen times the measure of a supplementary angle. What is the measure of each angle?

kap26 [50]

The term "supplementary" means that the two angles add up to 180°, which means we can write an equation:
17x + x = 180
18x = 180
÷ 18
x = 10
And now you can multiply 10 by 17, because it is 17 times the angle, to get 170° and 10° as your answer.

I hope this helps!

What is the line of symmetry for the parabola whose equation is y=-x^2-x+2

Delicious77 [7]

Answer:

$\huge \boxed{\sf \ \ x=-\dfrac{1}{2} \ \ }$

Step-by-step explanation:

Hello,

We need to express this parabola using this kind of expression

$y=a(x-b)^2+c$

and then, the line of symmetry will be the line x = b

Let's do it !

$\text{*** Complete the square ***} \\ \\ x^2+x=x+2\cdot \dfrac{1}{2}\cdot x=(x+\dfrac{1}{2})^2-\dfrac{1^2}{2^2}=(x+\dfrac{1}{2})^2-\dfrac{1^2}{4} \\ \\ \text{*** Apply it to our parabola } \\ \\y=-x^2-x+2=-(x^2+x)+2=-[(x+\dfrac{1}{2})^2-\dfrac{1}{4}]+2 = -(x+\dfrac{1}{2})^2+\dfrac{1+2*4}{4}= -(x+\dfrac{1}{2})^2+\dfrac{9}{4} \\ \\ \text{*** It comes ***} \\ \\ \Large \boxed{\sf \ \ y=-(x+\dfrac{1}{2})^2+\dfrac{9}{4} \ \ }$

So the line of symmetry is

$\huge \boxed{\sf \ \ x=-\dfrac{1}{2} \ \ }$

Hope this helps.

Do not hesitate if you need further explanation.

Thank you
