Answer:

x = y = - 1

Step-by-step explanation:

y = - 2x - 3

y = 7x + 6 -----> equation 1.

So,

7x + 6 = - 2x - 3

7x + 2x = - 3 - 6

9x = - 9

Divide 9 on both sides,

9x / 9 = - 9 / 9

x = - 1

Substitute x = - 1 in equation 1,

y = 7x + 6

= 7 ( - 1 ) + 6

= - 7 + 6

= 6 - 7

y = - 1

Therefore,

x = y = - 1

What is the constant term in the expression 8xy − 9x2 y − 5x 6

Burka [1]

Answer: 6

Step-by-step explanation:

I assume you meant to write 8xy − 9x2y − 5x + 6. The constant term in an expression is defined as a number by itself that contains no variables. Therefore, the answer is 6.

Write a word problem about equal groups and act it out to solve.

lina2011 [118]

Answer:

One scientist was working two molecules:

$BF_{3}, SO_{3}$

And verified that geometrically speaking, those are trigonal planar molecules made up of an equilateral triangle. He designed both molecules and classified them as Plane dihedral Groups. Was he correct? Why?

Step-by-step explanation:

Yes He was right. Place one atom in the centroid of the equilateral triangle (S or B), and each atom in each vertex(O or F).

We can apply geometric transformations (plane) rotations: R0, R2π/3, R4π/3

(And spatial ones, as R1, R2, R3 180º rotation over each median.)

Composite functions show that this is not an Abelian Group:

$R_{1}\circ\:R_{2}=R_{\frac{2\pi}{3}}\\R_{2}\circ\:R_{1}=R_{\frac{4\pi}{3}}\\$

What is the nth term of 5,11,17,23

rewona [7]

Answer:

6n - 1.

Step-by-step explanation:

Arithmetic sequence.

a1 = 5, d = 6.

nth term = a1 + d(n - 1)

= 5 + 6(n - 1)

= 5 + 6n - 6

= 6n - 1.

Help me out here!!! Wasn’t here for this lesson

CaHeK987 [17]

Answer:

(-1, -1.5)

Step-by-step explanation:

A coordinate is a point (a single place) on a graph. Coordinates can be recorded as (#, #).

The first number is the one on the x-axis (left/right) and the second number is the one on the y-axis (up/down). (x, y) The middle point, where the x-axis and y-axis meet is called the origin, and is at (0,0).

The point that marks the campground is at -1 on the x-axis and -1.5 on the y axis.

Because the y-axis has two lines for every whole number, the line in between is the halfway mark and counts as a 0.5 increment.
