Answer:

Statement 1: postulate; Statement 2: theorem

Step-by-step explanation:

Statement 1: If two angles form a linear pair, then they are supplementary angles - This is postulate.

Statement 2: If two lines intersect, then exactly one plane contains both lines - This is theorem.

A postulate is a statement that is considered to be true and is used as a starting point for further reasoning and arguments. Theorems are proven statements.

This isn't a great question, with the answer depending on how your book presents the material.

Supplementary angles are usually defined as a pair of angles which add to 180 degrees. It's then a theorem that a linear pair makes supplements.

So now we have to decide between postulate and definition for the plane formed by two intersecting lines.

Again I'd say at least from Euclid's definition this is a theorem.

none of the above

Choose two angles that are each separately alternate exterior angles with 412.

Alborosie

Answer:

∠2 and ∠5

Step-by-step explanation:

we know that

<u>Alternate Exterior Angles</u> are a pair of angles on the outer side of each of those two lines but on opposite sides of the transversal

In this problem

∠12 and ∠2 are alternate exterior angles

∠12 and ∠5 are alternate exterior angles

therefore

∠2 and ∠5 are each separately alternate exterior angles with ∠12

On the first play, the Wobegone High School football team lost 2 yards. On each of the next 3 plays they lost 2 yards. How many

inessss [21]

So if they lost 2 yards on the first play and on the following three plays they lost 2 yards they lost 4 yards total because it doesnt say they lost 2 yards on each of the three play so they would only lose 4 yards

I am extremely confused, can anyone help?

JulijaS [17]

Answer:

So I did most of you table for you:

First blank:4

Second blank:-4

Third blank:-8

Fourth blank: Left to you: Just plug in 6 into 1/2x^2-5x+4 (I will check)

Fifth blank: Left to you: Just plug in 8 into 1/2x^2-5x+4 (I will check)

The graph is D.

Step-by-step explanation:

So they have a table to fill in and they tell you in the first row what they want you to plug in

So the table is asking us to answer this:

What is h(0),h(2),h(4),h(6), and h(8).

h(0) means to replace x with 0 in $\frac{1}{2} x^2-5x+4$ .

$\frac{1}{2}(0)^2-5(0)+4$

$0-0+4$

$0+4$

$4$

So the first blank is 4 since h(0)=4.

h(2) means to replace x with 2 in $\frac{1}{2} x^2-5x+4$ .

$\frac{1}{2} (2)^2-5(2)+4$

$\frac{1}{2} (4)-10+4$

$2-10+4$

$-8+4$

$-4$

So the second blank is -4 since h(2)=-4.

h(4) means to replace x with 4 in $\frac{1}{2} x^2-5x+4$ .

$\frac{1}{2}(4)^2-5(4)+4$

$\frac{1}{2}(16)-20+4$

$8-20+4$

$-12+4$

$-8$

So the third blank is -8 since h(4)=-8

Maybe you can try the last 2 blanks in the table part. That is try computing h(6) and h(8). I will check it for you.

Now the points I have so far are (0,4) from the h(0)=4, (2,-4) from the h(2)=-4, and (4,-8) from the h(4)=-8.

I'm looking for a graph that goes through these points (0,4) , (2,-4) , and (4,-8).

By the way the only graphs that are worth looking at is C and D because they are open up. I know my curve for h(x)=1/2x^2-5x+4 should be a parabola open up because 1/2 is positive and 1/2 is the coefficient of x^2.

So Graph C has y-intercept (0,10) not (0,4) so Graph C is not right.

Graph D has y-intercept (0,4). It also goes through (2,-4) and (4,-8).

I don't know if you notice but the x-axis and y-axis are going up by two's in each graph.
