Answer:

From the graph, it is clear that the point of intersection is:

And the x-coordinate of the point of intersection for the two lines is:

Step-by-step explanation:

Given the system of equations

[tex]\begin{bmatrix}2x+y=-9\\ 2x-5y=-3\end{bmatrix}[/tex]

solving the system of equations

subtracting 2x+y = -9 from 2x-5y = -3

[tex]2x-5y=-3[/tex]

[tex]-[/tex]

[tex]\underline{2x+y=-9}[/tex]

[tex]-6y=6[/tex]

so

[tex]\begin{bmatrix}2x+y=-9\\ -6y=6\end{bmatrix}[/tex]

solving for y

[tex]-6y=6[/tex]

Divide both sides by -6

[tex]\frac{-6y}{-6}=\frac{6}{-6}[/tex]

[tex]y=-1[/tex]

[tex]\mathrm{For\:}2x+y=-9\mathrm{\:plug\:in\:}y=-1[/tex]

[tex]2x-1=-9[/tex]

[tex]2x=-8[/tex]

Divide both sides by 2

[tex]\frac{2x}{2}=\frac{-8}{2}[/tex]

[tex]x=-4[/tex]

Thus, the x-coordinate of the point of intersection for the two lines below will be:

[tex]x=-4[/tex]

Also, the graph is attached.

From the graph, it is clear that the point of intersection is:

And the x-coordinate of the point of intersection for the two lines is:

15 + 15 + 10 + 10 + 10 = 60/5 = 12 ( CODE WORD)

Step-by-step explanation:

1. There are different forms of linear equations. Slope intercept has it's equation y = mx + b

2. A proportional relationship has a constant rate of change.

ex: y =2x +5, then the rate of change is 2 and it only ever rises by 2.

3. A proportional relationship must pass through the origin in order to be a proportional relationship.

4. The variable M in slope-intercept form represents the slope. B represents the Y-intercept.

5. Standard form for a linear equation is Ax+By=C. Y = MX+B is slope-intercept form.

CODE WORD: 12 or Twelve is correct because 12 is the mean of all 5 answers.

Answer: 131

Step-by-step explanation: that one is good

Answer:

Answer:

y=1.125x

Step-by-step explanation:

9/8 is the ratio

so, I would do 9/8 which is 1.125. so, one euro is worth 1.125 dollar

y(dollars)=1.125x(euros)

TEST

27 dollars=1.125 • 24

done

Step-by-step explanation:

40 m

Answer:

m = -80

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Equality Properties

Step-by-step explanation:

Step 1: Define

-8 = m/-10 - 16

Step 2: Solve for m

Answer:

We have this equation:

-8 = m/-10 -1

We can add 8 at both sides:

-8 + 8 = m/-10 -16 + 8

0 = m/-10 -8

Now, we can multiply -8 by -10 with the objective of having the same denominator (-10) in all numbers:

0 = m/-10 - 8*(-10)/-10

0 = m/-10 +80/-10

Now, we can delete all denominators

0 = m + 80

And we can say m = -80

Now, we can replace it to see if it's true:

-80/-10 - 16 = -8, so we know that's true

-80/-10 -16 = 8 - 16 = -8 ..

Answer:

Solve for

n

by simplifying both sides of the equation, then isolating the variable.

Answer:

[tex]-6x^2\left(3x^5\right)=-18x^7[/tex]

Hence, option (A) is true.

Step-by-step explanation:

Given the expression

[tex]-6x^2\left(3x^5\right)[/tex]

[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^{b+c}[/tex]

i.e. [tex]x^2x^5=\:x^{2+5} \\[/tex]

so the expression becomes

[tex]-6x^2\left(3x^5\right)=-6\cdot \:\:3x^{2+5}[/tex]

[tex]\mathrm{Add\:the\:numbers:}\:2+5=7[/tex]

                  [tex]=-6\cdot \:3x^7[/tex]

[tex]\mathrm{Multiply\:the\:numbers:}\:6\cdot \:3=18[/tex]

                   [tex]=-18x^7[/tex]

Therefore,

[tex]-6x^2\left(3x^5\right)=-18x^7[/tex]

Hence, option (A) is true.

Answer: it’s a decimal

Step-by-step explanation:

9514 1404 393

Answer:

  44 inches

Step-by-step explanation:

The sides of a rhombus are all the same length, so we have ...

  AB = BC

  3x -4 = 2x +1

  x = 5 . . . . . . . . . add 4-2x

Then the side lengths are ...

  3x -4 = 3·5 -4 = 11

Four of them total 4·11 = 44 inches.

I assume it'd be 9°F.

-1 + 10 = 9

Either A or C

Step-by-step explanation:

Answer:

1/3

Step-by-step explanation:

I have a certain way of doing this, I will start from the Y-intercept, let's say its (0, 2), then, if the next point is (3, 4) i will count up 1, to get to point 3 on the graph, then count left/right to point 4. Thus making my slope 1/2.

Hope that made sense!
