I can't tell what that bottom coordinate is labeled as but I am going to call it Z.

I = (-3 , -2)

E = (-3 , -3)

Q = (2 , -4)

Z = (0 , -5

To reflect acrossed y = -2 means that

I = (-3 , -2)

E = (-3 , -1)

Q = (2 , 0)

Z = (0 , 1)

All you are doing is taking the y coordinate on each of them and basically mirroring it. Kind of like how you look into a mirror you see a reflection all your doing is changing the y values to be the opposite of what they are when you mirror them across y = -2.

I coordinate stays at (-3 , -2) because the y coordinate (x , y) is at y = -2. Y is vertical on the graph and x is horizontal.

Stefanie spends entire allowance one month she spends 1/2 of a on new clothes 1/4 on food 1/6 on movies and 1/12 on Music how mu
Komok [63]

Answer:

Option D: 1/3

Step-by-step explanation:

Let

x ------> the entire Stefanie's allowance

we know that

She spends on clothes (1/2)x

She spends on movies (1/6)x

To find out how much more does she spend on clothes that he does on movies, subtract the amount she spends on movies from the amount she spend on clothes

\frac{1}{2}x-\frac{1}{6}x=\frac{2}{6}x

Simplify

\frac{1}{3}x

therefore

She spends 1/3 more on clothes that he does on movies

Need help with this
Marrrta [24]

Answer:

law of cosines states c^2=a^2+b^2-2abc

b^2=26^2+24^2-2(26×24)cos 134°

b^2=676+576-1248cos134°

cos134= -0.6946

b^2=1252-12(-0.6946)

12×(-0.6946)= -8.3352

b^2=1252-(-8.3352)

b^2=1252+8.3352

b^2=1260.33

b=√1260.33

b=35.50

Andrew needs a ladder to hang hoilday lights. His house is 24ft tall and he has a flower bef that extends 4 ft out from the side
elena-14-01-66 [18.8K]

Answer: 24.33\ ft

Step-by-step explanation:

You need to draw a Right triangle as the one attached, where "x" is the lenght of a ladder Andrew will need to reach the top and be out of the flower bed.

You must apply the Pythagorean Theorem. This is:

a^2=b^2+c^2

Where "a" is the hypotenuse and "b" and "c" are the legs of the Right triangle.

If you solve for "a", you get:

a=\sqrt{b^2+c^2}

In this case, you can identify in the figure that:

a=x\\\\b=24\ ft\\\\c=4\ ft

Therefore, knowing those values, you can substitute them into  a=\sqrt{b^2+c^2} and then you must evaluate, in order to find the value of "x".

This is:

x=\sqrt{(24\ ft)^2+(4\ ft)^2}\\\\x=24.33 ft
