What is the x-coordinate of the point of intersection for the two lines below?
(2x + y = -9
(2x - 5y =-3
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:
(x, y) = (-4, -1)And the x-coordinate of the point of intersection for the two lines is:

What is the slope of the line.
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!

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.
On a recent day, 8 euros were worth $9 and 24 euros were worth $27. Enter an equation of the form y = kx to show the relationship between the number of euros and the value in dollars. Let y be the value in dollars and x be the number of euros.
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

Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
y + 5x = 1
5y - x = 5
Step 2: Rewrite Systems
y + 5x = 1
Subtract 5x on both sides: y = 1 - 5xStep 3: Redefine Systems
y = 1 - 5x
5y - x = 5
Step 4: Solve for x
Substitution
Substitution in y: 5(1 - 5x) - x = 5Distribute 5: 5 - 25x - x = 5Combine like terms: 5 - 26x = 5Isolate x term: -26x = 0Isolate x: x = 0Step 5: Solve for y
Define equation: 5y - x = 5Substitute in x: 5y - 0 = 5Subtract: 5y = 5Isolate y: y = 1Triangle PQR is similar to triangle VST with a scale factor of 2:5, find the value of x. (show your work for credit) * M (15 Points) T 1 1 1 R Q x 45 28 P V S 30

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.

Solve for m: -8 = m/-10 - 16
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 ..
