That would be a translation. I know this because it didn't reflect, rotate or go down in size so it's not a dilation either. That leaves translation because it only moved!
Answer:
Step-by-step explanation:
Here the coefficients of this quadratic equation are {7, -1, -3}. Note that the given equation must be rewritten in standard form: 7x^2 - x - 3.
Then the discriminant, b^2 - 4ac, is (-1)^2 - 4(7)(-3), or 1 + 84, or 85. Because this discriminant is positive, the given quadratic has two real, unequal roots. These roots are:
-(-1) ± √85
x = ------------------
14
or:
1 ± √85
x = ------------------
14
Answer:
1:2
Step-by-step explanation:
1 yard is 3 feet
6 ft = 2 yd, so the ratio is 2 yd : 4 yd = 2:4 = 1:2
