Write an equation of the line that passes through (18, 2) and is parallel to the line 3y - x = -12.

Alona [7]

Answer:

3y=x-12

y=x/3-4

m=1/3

At (18,2)

y-2=1/3(x-18)

y-2=x/3 - 6

y=x/3 - 4

Triangle ABC IS an isosceles triangle AB=BC m

True [87]

Answer:

<em>The measure of angle A is 73°</em>

Step-by-step explanation:

<u>Isosceles Triangles</u>

An isosceles triangle is a triangle with exactly two congruent sides. The angles the congruent sides form with the third side are also equal.

The triangle ABC is isosceles and AB congruent with BC. The angle at B measures 34°.

The other two angles are congruent, i.e. their measures are the same. Since the internal angles of a triangle sum 180°:

$2*m\angle A=180^\circ - 34^\circ =146^\circ$

Thus:

$m\angle A=146^\circ /2=73^\circ$

The measure of angle A is 73°

Which term best describes the expression 3x2y4 + 5x + 1?

notka56 [123]

Answer:

Trinomial.

Step-by-step explanation:

Note how much terms there are in the given expressions:

Term 1: $3x^{2}y^{4}\$

Term 2: $5x$

Term 3: $1$

Note each meaning of the terms:

Monomial: Having only one term.

Binomial: Having two terms.

Trinomial: Having three terms.

Polynomial: Typically used to describe expressions with 4 or more terms.

In this case, there are only 3 terms, and so your answer is Trinomial.

HELP WITH MATH PLEASE

sergey [27]

Answer:

1) (-3,-2)

2) x=-3

Step-by-step explanation:

1) The vertex of a parabola is the turning point that is the minimum or maximum of the graph, based on the shape of the parabola. In this case, the vertex is the minimum. By looking at the coordinate points, we can tell that the minimum value where the graph changes the direction is at (-3,-2).

2) The line of symmetry is the line on the graph that cuts the shape exactly in half. This means that if you were to fold the graph along this line, the two sides would be identical. All parabolas have a line of symmetry and it always matches the vertex. The equation for the line of symmetry will be x= whatever the x-value of the vertex is. So, for this graph, the line of symmetry is x=-3.
