2.1. 5a + 2b
2.2. -4x
2.3. 3x + 5
2.4. 10y
Answer: x = 4
Step-by-step explanation:
4x = 13 + 3
4x = 16
x = 16/4
x = 4
Answer:
<h2>1) y = 5</h2>
Step-by-step explanation:
x = 4 it's a vertical line.
Perpendicular line to a vertical line is a horizontal line.
A horizontal line has equation y = a.
A horizontal line passes through the point (3, 5) → x = 3 and y = 5.
Therefore the equation is y = 5
Answer:
4x⁴y
Step-by-step explanation:
Square the -x
2x·2xy·(-x)²= 2x·2xy·x²
Use the commutative property of multiplication to rearrange the order
2x·2xy·x² = 2·2·x·x·x²·y
Use the associative property of multiplication to combine like terms
2·2·x·x·x²·y = ( 2·2)·(x·x·x²)·y
Simplify
( 2·2)·(x·x·x²)·y = 4x⁴y
Answer:
x=24.1
Step-by-step explanation:

cos(24°)=22/x
cos(24)= 0.9135
0.9135=22/x
0.9135x=22
x=22/0.9135
x=24.1
