Svetllana [295]

Answer:

(0, 7/12)

Step-by-step explanation:

to find the y intercept we equate x to 0.

hence,

f(0) = 7/12

the coordinate is (0, 7/12)

A 14 foot is cut into two pieces so that one piece is 3 feet longer than twice the shorter piece
DochEvi [55]
To answer the question above, let x be the shorter one of the pieces. With the variable, we can express the longer piece as 2x + 3. Based on the given, the sum of the lengths of these pieces should sum up to 14 ft. 

                                        2x + 3 + x = 14 ft, x = 3 2/3 ft

Substituting this value for the longer piece, we get 10 1/3 ft. Thus, the lengths of the pieces are 3 2/3 ft and 10 1/3 ft.

Who can help me ! <br> .... thanks
Tasya [4]
Given that there is no any option to choose I am going to help you according to the concepts of Congruent Triangles. Two triangles are congruent if and only if:

1. They have:exactly the same three sides
2. exactly the same three angles.

<span>There are five ways to find if two triangles are congruent but in this problem we will use only two.


First Answer:

<u>ASA criterion:</u> </span><em>A</em><span><em>ngle, side, angle</em>. This means that we have two triangles where we know two angles and the included side are equal.</span>

So:

If ∠BAC = ∠DEF and \overline{AC}=\overline{DE}

<em>Then ΔABC and ΔEFD are congruent by ASA criterion.</em>

Second answer:

<u>SAS criterion:</u> <em>S</em><span><em>ide, angle, side</em>. This means that we have two triangles where we know two sides and the included angle are equal.
</span>
If \ \overline{AC}=\overline{DE} \ and \ \overline{BC}=\overline{DF}

<em>Then ΔABC and ΔEFD are congruent by SAS criterion.</em>
