Answer:
1. x = 4 and y = 1
2. x= 5 and y = 3
Use the examples below to complete 3 and 4.
Step-by-step explanation:
To solve each system of equations, use elimination.
1. Stack the equations and subtract to perform elimination.
2x + 2y = 10
- x + 2y = 6
-------------------------
x = 4
Substitute x = 4 into an equation to solve for y.
2(4) + 2y = 10
8 + 2y = 10
2y = 2
y = 1
2. Stack the equations and subtract to perform elimination.
3x + y = 18
- 2x + y = 13
-------------------------
x = 5
Substitute x = 5 into an equation to solve for y.
3(5) + y = 18
15 + y = 18
y = 3
Continue the same method for numbers 3 and 4.
Area of square = 5 x 5 = 25 cm^2
area of rectangle = 25 x 10 = 250 cm^2
area of figure = 25 + 250 = 275 cm^2
hope it helps
Answer: we can’t see graphs but I can help you if you show me them
Step-by-step explanation:
40,600x10=406,000 lol dude its easy
Multiplying out the equation (x + 2)(4x - 3) and arranging in descending powers order gives us the quadratic form as; 4x² + 5x - 6
<h3>How to expand quadratic equations?</h3>
We want to expand the quadratic equation given as;
(x + 2)(4x - 3)
Multiplying out gives us;
4x² + 8x - 3x - 6
⇒ 4x² + 5x - 6
Thus, we can conclude that multiplying out the equation (x + 2)(4x - 3) and arranging in descending powers order gives us the quadratic form as; 4x² + 5x - 6
