X=3 y=-2
4x - 6y
4(3) - 6(-2)
12 - (-12) (two negatives cancel out)
12 + 12 = 24
answer: 24
False, it is on the horizontal.
29.) This is simply interpreting the linear function.
The function:
96+2.1x
a.) The 96 is what you start with from the beginning. So, we know Rachel weighed 96 ounces when she was born.
b.) Again, interpretation. The 2.1 is the slope, or the change in the line. So we know that Rachel gains 2.1 ounces each day.
30.) For this one, you just have to plug 9 into the equation for x.
The process of translation means that only the position
of the point is being changed. No other parameters are changed such as
reflection or rotation is being made.
In this case the translation is solely made on the y
axis. A translation of (x, y – 4) means that the point is moved down by 4
units.
So in this case, our point V is at coordinates of (-2, 4)
so a translation of (x, y – 4) means that V’ is moved down by 4 units and the
new coordinates are:
V’ = (- 2, 4 – 4)
V’ = (-2, 0)
answer:
(-2, 0)
