Answer:

12

Step-by-step explanation:

Pythagorean Theorem states that

a² + b² = c²

plug in your terms

9² + b² = 15²

81 + b² = 225

then subtract 81 from 225 to get your b²

b² = 144

then find the square root of 144

the square root is 12 because 12 x 12 = 144

Maya wrote the expression 3+5+4.5 to represent the total distance that she traveled. Which statement best describes Maya’s expre
harina [27]

<u>Answer:</u>

The statement, Maya’s expression will generate the correct sum because of the associative property will describe the best.

<u>Solution: </u>

Maya’s expression will generate the correct sum because of the associative property.

Maya wrote the expression 3+5+4.5

As per commutative property of addition if we change the order still the sum will be same, which means (a + b) = (b + a)

Here also, (3 + 5) + 4.5 = 8+4.5 = 12.5

Again 3 + (5+4.5) = 3+9.5 = 12.5

As both the results are same, hence this is meeting the commutative property of addition.

EMERGENCY!! TIME CRUNCH!! PLEASE HELP!!

Answer:

y=-6x+8

Step-by-step explanation:

(-2,2) and (-8, 1)

m=\frac{y2-y1}{x2-x1}

m represents your slope.

so m=\frac{1-2}{-8-(-2)}

this gets you 1/6 (this is your slope from these two points but we ened to find the perpendicular slope)

all you do is take the is make 1/6= -6 (this your perpendicular slope, basically just take the reciprocal of the original slope)

so now use the equation y-y1=m(x-x1) ---> the y1, and x1 represent the place holders for the point (3,-10)

y+10=-6(x-3) (move the 10 over)

y=-6(x-3)-10

y=-6x+18-10

y=-6x+8
