Answer:
(B) all numbers less than 7
Step-by-step explanation:
Given the inequality:
x<7
It means that:
- x cannot be equal to 7
- x cannot be greater than 7
Therefore, x<7 consists <u>of all numbers less than 7.</u>
<u>Answer:</u>
(x,y)→(y,x); A' is at (2, −7)
<u>Step-by-step explanation:</u>
According to the given image, the coordinates of the kite ABCD are:
A (-7, 2)
B(-5, 3)
C(-2, 2)
D(-5, 1)
Kite ABCD is then reflected over the line y = x, the main rule to find the coordinates of the images is (y, x).
So for point A (-7, 2), the coordinates of the point A' after reflecting over the line y=x will be A' (2, -7).
We want to get b alone so I would start by multiplying 2 to get it on the other side of the = sign. So then I have 2L=a-b. I would subtract a on both sides and then I would have 2L-a= -b. We don't want a -b so I would multiply everything by -1 so then the answer would then be a positive b= -2L+a
Answer:
D
Step-by-step explanation:
We know it has 2 distinct zeros. This means the discriminant of the quadratic is positive and must have 2 real zeros that can be rational or irrational. We also know the quadratic has rational coefficients which means both are either rational or irrational. They can not be one of either. Since it tells us one is rational, the other must be too.
