Mathematics

Answer:

No

Step-by-step explanation:

By the converse of Pythagoras' identity.

If the longest side squared equals the sum of the squares of the other 2 sides then triangle is right.

longest side = 15

15² = 225

4² + 9² = 16 + 81 = 97 ≠ 225

Thus sides do not represent a right triangle.

What is the slope-intercept form of this equation 3x+9y=18
irina [24]

y = mx + b

m: slope

b: y-intercept

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

3x + 9y = 18

-3x            -3x

9y = -3x + 18

/9           /9

y = -3/9x + 2   OR  y = -1/3 + 2

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

m = -3/9 OR -1/3

b = 2

Liam uses 2 quarts of yellow paint and adds 3 1/4 Jars of blue paint.Evan uses 1/2 quarts of yellow paint and adds 5 1/2 of red
EleoNora [17]

Answer:

2 + (13/4)x = 1/2 + (11/2)y

Step-by-step explanation:

Let each jar of paint used by Liam be x

Let each jar of paint used by Evan be y.

Liam uses 2 quarts of yellow paints and adds 3 1/4 jars of blue paint. so we have

2 + 3 1/4x

= 2 + (13/4)x

Since Evan also uses 1/2 quarts of yellow paints and add 5 1/2 jar of red paint, we have

1/2 + 5 1/2y

= 1/2 + (11/2)y

Since they end up with the same volume of paint, we have

2 + (13/4)x = 1/2 + (11/2)y
