Intersection (Euclidean geometry) In geometry, an intersection is a point, line, or curve common to two or more objects (such as lines, curves, planes, and surfaces). The simplest case in Euclidean geometry is the intersection of two distinct lines, which either is one point or does not exist if the lines are parallel.

What conclusions can you draw about the roots of the equation x^3+x^2-2x+12=0

nexus9112 [7]

Answer:

x=-3

Step-by-step explanation:

If x=-3, then

x³+x²-2x+12=-27+9+6+12=-27+27=0

If this is true, then x+3 is a factor. So:

x³+x²-2x+12/x+3=x²-2x+4

So the factors of x³+x²-2x+12 are:

(x+3)(x²-2x+4)

((x²-2x+4) has no real roots)........

Factor 64x^2-25y^2<br><br> enter your answer in the box

OLEGan [10]

Answer:

(8x - 5y)(8x + 5y)

Step-by-step explanation:

To factor the expression, use the difference of squares pattern. A difference of squares is subtraction between two perfect squares and factors as a² - b² = (a-b)(a+b).

The expression has the perfect squares 64x² and 25y². Take the square root of each. The factors become (8x - 5y)(8x + 5y).

Answer:

A is (10,0)

B is (3, 3).

Step-by-step explanation:

First we calculate the coordinates of the point A.

Here, y = 0 so we have:

7(0) - 3x + 30 = 0

-3x + 30 = 0

x = -30/-3 = 10.

So A has coordinates (10,0).

Next we find the coordinates of the points where the line passes through the y axis. Here x = 0:

7x - 3(0) = 30

x = 30/7.

So the point is (0, 30/7).

Let the point B have coordinates (x1, y1)

Now x1 = y1 (given).

If we draw a line from B perpendicular to the x axis ( its length will be = y1) then we have 2 similar triangles.

So as corresponding sides are in the same ratio:

y1/ (30/7) = (10-x1) / 10

But as x1 = y1:

x1/ (30/7) = (10-x1) / 10

7 x1 / 30 = (10-x1) / 10

70 x1 = 30(10 - x1)

70x1 = 300 - 30 x1

100 x1 = 300

x1 = 3

So the coordinates of B are (3,3)

Checking the solution to the equation:

LHS = 3 / 30/7 = 3*7 / 30 = 21/30 = 7/10.

RHS = (10 -3 ) / 10 = 7/10.

What is 2x+y=8 and x-2y=-1

Dafna1 [17]

The solutions of x and y?

2x+y=8...(1)
x-2y=-1...(2)
for (2), x=-1+2y...(3)
sub(3) into(1),
2(-1+2y) +y=8
-2+4y+y=8
5y=10
y=2
sub y=2 into(3)

x=-1+2(2) =3
therefore, x=3,y=2
