How many solutions does the system of equations below have? y = 3x + 4 y + 6 = 3x

Mathematics

1 answer:

Troyanec [42]3 years ago

6 0

Answer:

0 / no solutions

Step-by-step explanation:

Rewrite both in terms to the form y = equation.

EQ1: y = 3x + 4 (already in correct form)

EQ2: y = 3x - 6 (subtracting 6 from both sides).

Now suppose there is an intersection, then:

3x + 4 = 3x - 6, subtracting 3x from both sides gives:

4 = -6, which is a contradiction!

Therefore there are 0 / no solutions

Suppose segment PQ has one endpoint at P (0,0). If T (6,3) is a point 3/10 of the way from P to Q, find the coordinates of Q.

mixer [17]

Answer:

Q(20,10)

Step-by-step explanation:

If point T (6,3) is a point 3/10 of the way from P(0,0) to Q(x,y), then

$\overrightarrow {PT}=\dfrac{3}{10}\overrightarrow {PQ}.$

Find the coordinates of the vectors $\overrightarrow {PT},\ \overrightarrow {PQ}:$

$\overrightarrow {PT}=(6-0,3-0)=(6,3);\\ \\\overrightarrow {PQ}=(x-0,y-0)=(x,y).$

Thus,

$(6,3)=\dfrac{3}{10}(x,y),\\ \\(x,y)=\dfrac{10}{3}(6,3)=(20,10).$

A square is 3.2 millimeters (mm) on each side. What is the area of the square?

Ad libitum [116K]

B
Reason:
A square has congruent sides. The length of one side is the length of every side. Multiply 3.2 by 3.2 (area formula) then you get 10.24.
