Roman completed the square to solve the equation 0=−x2+6x−15 0 = − x 2 + 6 x − 15 as follows. Step 1: x2−6x+15=0 x 2 − 6 x + 15

= 0 Step 2: x2−6x+15−15=0−15 x 2 − 6 x + 15 − 15 = 0 − 15 Step 3: x2−6x+9=−15+9 x 2 − 6 x + 9 = − 15 + 9 Step 4: (x−3)2=−6 ( x − 3 ) 2 = − 6 Step 5: x−3=±−6−−−√ x − 3 = ± − 6 Step 6: x−3−3=−3±−6−−−√ x − 3 − 3 = − 3 ± − 6 Step 7: x=−3±i6√ x = − 3 ± i 6 Did Roman make a mistake? If so, where?

Kamari spent $74.92 on Christmas present for her four cousin's if she spends the same amount on each how much did she spend on e
Amiraneli [1.4K]
You know that $74.92 is the total, and you need to know how much of that total was split between 4 cousins. So that means you have to divide 74.92 by 4. This gives you $18.73.
Hope this helped! ;)

Write an equation of the line that passes through the point (3,0) and<br> has the slope, m = -2.
kenny6666 [7]
The equation of a line is Y=mx+b
You know that the slope is -2 and the slope is 'm' so sub it into the equation.
Y=-2x+b
To have an equation of a line you need the 'b' or 'y' intercept and the slope.
This means you have to find the 'b' because you already know the slope which is -2. To find the 'b' you have to sub in the coordinates and then solve for 'b'
Y=-2x+b
(x,y)
(3,0)
0=-2(3)+b
0=-6+b
6=b
Therefore the equation of the line is Y=-2x+6 <span />
