1 km=0.621mi
xkm=106 mi
x=106/0.621=170.66
b is the answer
X=75/17 i did the math and got that answer
Answer:
B.x2-4x=18
x2-4x+4=18+4
Step-by-step explanation:
When you complete the square your quadratic equation must be written in the standard form which is ax^2+bx+c.
First you are going to want to move your c term to the right (in this case move -18 to the right by adding 18 to both sides). This will get you x^2-4x=18. Now you are going to need to complete the square. To complete the square you divide the number in the bx term (in this case -4) by 2 and then square it. (-2^2=4 since a negative times a negative equals a positive). Now that you have 4 you are going to add it to both sides to get x2-4x+4=18+4.
<span>2y=3x-7
y = 3/2x - 7/2
y = 1.5x - 3.5 so slope = 1.5
</span><span>line parallel so it has same slope = 1.5
</span>
y +1 = 1.5(x - 0.5)
y + 1 = 1.5x - 0.75
y = 1.5x - 1.75
answer: equation y = 1.5x - 1.75
