Hope this helps. You should transfer them into fractions, change to common dominators. then subtract and then you get your final answer, you may reduce it from there or not.
Answer:
Step-by-step explanation:
Step 1 . Let take X1 = 1 Y1 = 5 , X2 = 3 and Y2 = 2
Step 2. Slop of the line is (Y2-Y1)/(X2-X1)
Step 3. Point value (2–5)/(3–1)
Answer is —3/2 = —1.5
Answer:
(3×10^3)+(3×10^2)+(2×10^1)+(7×10^0)
Answer:
The length of side AB is 5 units
Step-by-step explanation:
* Lets revise how to find the distance between two points
- If there are two points their coordinates are (x1 , y1) and (x2 , y2),
then we can find the distance between them by this rule:
d = √[(x2 - x1)² + (y2 - y1)²]
- Now lets solve the problem
∵ A = (4 , -5)
∵ B = (7 , -9)
- To find the length of AB use the rule of the distance above
- Let point A is (x1 , y1) and point B is (x2 , y2)
∵ x1 = 4 and x2 = 7
∵ y1 = -5 and y2 = -9
∴ AB = √[(7 - 4)² + (-9 - -5)²]
∴ AB = √[(3)² + (-4)²]
∴ AB = √[9 + 16] = √25 = 5
* The length of side AB is 5 units
Well 1 package=3, so if she buys 5 packages it's 5*3=15. She still has 2 left so you take 15+2=17. She will have 17 juice boxes in total.
