X=16, y= \sqrt{2}

you can extend down a vertical line, so you know that portion of x is 7, and that side of the triangle is 9, since 45-90-45 triangles have 2 legs of equal length. 
then you know the other leg of the triangle is 9, and adding 9+7 x=16. to find y you can know that 45-90-45 triangles have sides in a 1:1:\sqrt{2} ratio, so this triangle is 9:9:9\sqrt{2}

Please help me out !! Asap
Paraphin [41]

Answer:

(1,5)

Step-by-step explanation:

y = 4x+1

y = 2x+3

Set the two equations equal

4x+1 = 2x+3

Subtract 2x from each side

4x+1-2x = 2x+3-2x

2x+1 = 3

Subtract 1 from each side

2x+1-1 =3-1

2x=2

Divide by 2

2x/2 =2/2

x =1

Now find y

y =4x+1 = 4(1)+1 =4+1=5

Help please? I’m not too sure what to do?
mamaluj [8]

Answer:

75

Step-by-step explanation:

Average needed to get grade C = 70

Average = Total Amount / No of Items.

No of items = 4

therefore Total needed = 70 x 4 = 280

current total score = 66.75 + 66 + 72.25 = 205

the fourth test minimum score = 280 - 205 = 75

When filled, a particular round balloon has a diameter of 14 inches (in.).
icang [17]

Answer:

1436.76 in.^3

Step-by-step explanation:

This question means to find the volume of a sphere with a diameter of 14 inches. The formula for the volume of a sphere is 4/3πr^3, so we need to find the radius, which is half the diameter. Half of the diameter is 7 inches, so now we can plug in our values to find the volume is about 1436.76 cubic inches.
