What is the x-coordinate of the point of intersection for the two lines below?
(2x + y = -9
(2x - 5y =-3
Answers
Answer:
From the graph, it is clear that the point of intersection is:
(x, y) = (-4, -1)And the x-coordinate of the point of intersection for the two lines is:
x = -4Step-by-step explanation:
As we know that the solution of the system of equations is the point of intersection. Let us solve it.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:

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.

Solve for m: -8 = m/-10 - 16
Answers
Answer:
m = -80
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define
-8 = m/-10 - 16
Step 2: Solve for m
Add 16 to both sides: 8 = m/-10Multiply -10 on both sides: -80 = mRewrite: m = -80Answer:
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 ..
