Answer:
Step-by-step explanation:
Use the distance formula:
1. Fill in the values:
2. Subtract inside the parenthesis:
3. Simplify:
The distance between the points is
X < y: This means "x is less than y"
<span><span>x </span></span>≤ y<span><span>: This means " x is less than or equal to y"
</span></span><span><span>x > y: This means " x is greater than y"
</span></span><span><span>x </span></span>≥ y<span><span>: This means " x is greater than or equal to y"
</span></span>
You use these inequality symbols to compare two things. They are used to depict a range of possible values.
Answer:
B: y= 5/2x + 1/2
Step-by-step explanation:
Equation:
y = mx + b
Find the slope (m):
Two points are given, (-1,-2) (1,3)
m = y₂ - y₁ / x₂ - x₁
m = 3 -(-2) / 1 -(-1)
m = 3 + 2 / 1 + 1
m = 5/2
y = 5/2x + b
Find b:
As you can see from the graph, the line intersects the y-axis through point 1/2.
Equation:
y = 5/2x + 1/2
amount spent = y
pounds of potatoes = x
dollars per pound = m
other ingredients cost = b
y=mx+b
Answer: 2 and a half slices
Step-by-step explanation: 5/2 is 2.5
