Answer:
75, 77
Step-by-step explanation:
Let the first odd number = 2x -1
Let the second odd number = 2x + 1
2x - 1 + 2x + 1 + 18 = 170 Combine like terms on the left.
4x + 18 = 170 Subtract 18 from both sides.
4x = 170 - 18 Combine like terms on the right
4x = 152 Divide by 4
4x/4 = 152/4
x = 38
2 * 38 - 1 = 75
2 * 38 + 1 = 77
When there are no special grouping symbols, math problems are solved from left to right. Although there are other important rules about the order in which you do the operations (addition/subtraction/multiplication/division) in a math expression or equation, this lesson will focus on grouping symbols. The rest of the order of operations rules will be explained in the Determining Order of Operations lesson. To help prevent confusion as you learn how to use the grouping symbols, this lesson will only use addition and subtraction.

Answer: Vertex (-3, 1) and x-intercept (-4, 0), (-2, 0)
Answer:
Option (4)
Step-by-step explanation:
Slope a line passing through two points
and
is given by,
m = 
Since, blue line is passing through two points (-4, -2) and (0, 4),
Slope of the blue line = 
= 
Similarly, green line is passing through two points (-4, 1) and (0, -2),
Slope of the green line = 
= 
Since, 
Neither these slopes are opposite reciprocals.
Therefore, both the lines are neither parallel nor perpendicular.
Option (4) will be the correct option.
