Answer:

Step 1: Simplify both sides of the equation.

Step 2: Subtract 3 from both sides.

Step 3: Use quadratic formula with a=0.25, b=2.5, c=2.25.

You can just use Step 3 itself

Which diagram shows parallel lines cut by a transversal?

Arada [10]

Only the third model shows parallel lines cut by a transversal.

We can solve this problem by using some properties that parallel lines cut by a transversal have. First of all, corresponding angles are congruent, and since the angles in figure 1 are corresponding but not congruent, that means that figure one is out.

In addition, in figure two, alternate exterior and interior angles of parallel lines intersected by a transversal are congruent, so since they are not in the picture, that means that this figure is also out.

Figure three is correct because since those are same side interior angles, they need to be supplementary for those to be two parallel lines intersected by a transversal. Since they do, in fact, add up to 180°, that means that the answer is figure three.

A fish is 4 feet under water and swims up 1 foot towards the surface. What is its position

vampirchik [111]

Answer: $\Large\boxed{-3~\text{feet under water}}$

Step-by-step explanation:

Given information

$\text{Fish is 4 feet under water (-4)}$

$\text{Swims up by 1 foot (+1)}$

Derived expression from the given information

$\text{Position = Initial + Change}$

Substitute values into the given expression

$\text{Position = }(-4)+(1)$

Simplify the position

$\text{Position = }-3$

Therefore, the current position of the fish is:

$\Large\boxed{-3~\text{feet under water}}$

Hope this helps!! :)

The measure of an angle is 39°. What is the measure of its complementary angle?

Novosadov [1.4K]

Answer:

51 degrees

Step-by-step explanation:

Complementary angles are two angles whose sum is (90degrees). If one is given an angle measure and needs to find its complementary angle, then all one has to do is subtract the given angle measure from (90degrees).

90 - 39 = 51
