Answer:
3 to 12 and 1 to 4:
Step-by-step explanation:
3 to 12 would be = 3:12
1 to 4 would be = 1:4
Since ratios can also be fractions, think of it this way. 3:12 as 3/12, and 1:4 as 1/4.
Now, if you simplify, you will see they are equivalent to each other,
3/12 = 1/4
(x - 1)(x - 4)(x + 7) = 0 ⇔ x - 1 = 0 or x - 4 = 0 or x + 7 = 0
x = 1 or x = 4 or x = -7
Answer: c. (1; 0); (4; 0); (-7; 0)
Answer:
Step-by-step explanation:
Since the coordinates of P are (0, 1), this makes P the y-intercept of that line. The y-intercept exists where x = 0. And in the coordinate (0, 1), x does in fact equal 0.
Since the one coordinate given in Q is (?, 0), this means that Q is the x-intercept of the line. The x-intercept exists where y = 0. And in the coordinate (?, 0), y does in fact equal 0. So in order to solve for the x coordinate of Q, we plug in a 0 for y and solve for x:
3(0) - 4x = 12 and
-4x = 12 so
x = -3
