Answer:
(-4, 2)
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesAlgebra I
Solving systems of equations using substitution/eliminationSolving systems of equations by graphingStep-by-step explanation:
Step 1: Define systems
-9x - 5y = 26
4x - 4y = -24
Step 2: Rewrite systems
4x - 4y = -24
Add 4y to both sides: 4x = 4y - 24Divide 4 on both sides: x = y - 6Step 3: Redefine systems
-9x - 5y = 26
x = y - 6
Step 4: Solve for y
Substitution
Substitute in x: -9(y - 6) - 5y = 26Distribute -9: -9y + 54 - 5y = 26Combine like terms: -14y + 54 = 26Isolate y term: -14y = -28Isolate y: y = 2Step 5: Solve for x
Define original equation: 4x - 4y = -24Substitute in y: 4x - 4(2) = -24Multiply: 4x - 8 = -24Add 8 to both sides: 4x = -16Divide 4 on both sides: x = -4Step 6: Graph
Check the solution set.

___________
1000000000
It is in p/q form
Answer:
[tex]\frac{125}{999}[/tex]
Step-by-step explanation:
Create 2 equations with the repeating numbers 125 placed after the decimal point.
let x = 0.125125125 → (1) ← multiply both sides by 1000 )
1000x = 125.125125125 → (2)
Subtract (1) from (2), thus eliminating the repeating decimal
999x = 125 ( divide both sides by 999 )
x = [tex]\frac{125}{999}[/tex] ← in the form [tex]\frac{p}{q}[/tex]

Answer:
20
Step-by-step explanation:
4 × 5 × 1 = 20 (cm³)
Hope it help, please give me Brainlest!
Answer:
20
Step-by-step explanation:
The formula for volume:
[tex]V=length*width*height\\\\V=lwh[/tex]
Multiply all given values together:
[tex]V=4*5*1\\\\V=20*1\\\\V=20[/tex]
The volume of the box is 20cm³.
:Done
Note:
"Cubic" centimeters means cm³. The exponent is used because you multiplied 3 dimensions.
Another example would be with area. To find this, you multiply length by width, resulting in area², because you mutliplied 2 dimensions.

Answer:
Hope it will help you
Step-by-step explanation:
Option BJonathan can buy 33 games.
What is equation?The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
Given that, Jonathan decides to go to an arcade to play some games. He sets a limit of $35 that he will spend
Let he can buy x games, then the equation will be,
0.75x+10 = 35
0.75x = 25
x = 100/3 ≈ 33
Hence, Jonathan can buy 33 games.

Over the interval [0, 2), what are the solutions to sin(2x) = 2cos(x)? Check all that apply,

pi/2 and 3pi/2
Step-by-step explanation:

The required solutions to sin(2x) = 2cos(x) are the following as : [tex]\:x=\frac{\pi }{2}+2\pi n,\:x=\frac{3\pi }{2}+2\pi n[/tex].
What are Trigonometric functions?Trigonometric functions are defined as the functions which show the relationship between the angle and sides of a right-angled triangle.
The equation of trigonometry functions is given in the question:
sin(2x) = 2cos(x)
We have to determine the solution to the given trigonometry equation
As per the question, we have
⇒ sin(2x) = 2cos(x)
Rewrite the above trigonometry equation,
⇒ sin(2x) - 2cos(x) = 0
⇒ 2sin(x)cos(x) - 2cos(x) = 0
Common factor out from the equation,
⇒ 2cos(x)[sin(x) - 1] = 0
Solving each part separately
2cos(x) = 0 and sin(x) - 1 = 0
cos(x) = 0 and sin(x) = 1
[tex]\:x=\frac{\pi }{2}+2\pi n, and \:x=\frac{3\pi }{2}+2\pi n[/tex].
Thus, the required solutions to sin(2x) = 2cos(x) are the following: [tex]\:x=\frac{\pi }{2}+2\pi n,\:x=\frac{3\pi }{2}+2\pi n[/tex].

8. The number of dandelions growing on your lawn triples every 3 days. If your lawn started out
with 15 dandelions, how many dandelions would you have after 3 weeks?
Answer:
There will be 32805 dandelions after 3 weeks
Step-by-step explanation:
To determine number of dandelions after 3 weeks
1 week = 7 days
∴ 3 weeks = 3 × 7 days = 21 days
Hence, we will determine the number of dandelions after 21 days.
From the question,
The number of dandelions growing on the lawn triples every 3 days and if the lawn started out with 15 dandelions,
Then, After 3 days, there will be 3 × 15 dandelions = 45 dandelions
After 6 days, there will be 3 × 45 dandelions = 135 dandelions
After 9 days, there will be 3 × 135 dandelions = 405 dandelions
After 12 days, there will be 3 × 405 dandelions = 1215 dandelions
After 15 days, there will be 3 × 1215 dandelions = 3645 dandelions
After 18 days, there will be 3 × 3645 dandelions = 10935 dandelions
After 21 days, there will be 3 × 10935 dandelions = 32805 dandelions
Hence, there will be 32805 dandelions after 3 weeks.
