Answer:
yes
Step-by-step explanation:
F(x) means the function defined at that x value. It really just means what y value when x is equal to that input. So we can see clearly that A is false. They’re nearly opposite y values. B is also obviously false since the y values aren’t equal. C is the same case, the y values aren’t equal. D is true. When x = -2 for both functions, we can see the y value is the same. They also intercept, so that’s a pretty dead giveaway
D.)
Answer:
Step-by-step explanation:
The area for a trapezoid is
h is the length of ST, one of the bases is the length of MK, and the other base is the length of AS. First we'll find h:
The coordinates for S are (0, -2) and T are (1, 2). Using the distance formula:
and
. So h = √17
Now for the length of MK. The coordinates for M are (-7, 4) and for K (5, 1). Using the distance formula again:
and
so
which simplifies to
. So MK = 3√17.
Now for the length of AS. The coordinates for A: (-4, -1) and for S: (0, -2). Using the distance formula one more time:
and
and
. So AS = √17.
Now we can fill in our area formula:
Simplifying a bit:
and simplifying a bit more:
and
A = 34
<span>Students could also give the answers as green to blue, blue to green, truck , car to truck, blue to total, and green to total.Some students may write part to part ratios. When the class comes back together, this could be a good time to discuss why a part to whole ratio is more useful when comparing statements that include percents. Students may need to be reminded that percents are a form of a part to whole comparison where the whole is 100.hoose different pairs of small groups to post diagrams and explain how the diagram helped them to see the relationship between the fractions, percents, and decimals.</span>
