Answer:
1. y = 5 - 2x
2. b = a - 3
3. x = 5y - 12
4. c = (12+7d)/3
5. y = (24-4x)/3
6. x = (4 - 3y)/2
Step-by-step explanation:
Given :
7x is an odd integer.
To Find :
The next odd integer as an algebraic expression in x.
Solution :
All positive integers are :
1 , 2 , 3 , 4 , 5 , ......
From the above series we noticed that every other odd number is 2 more than the previous one.
So , 7x is an odd number.
Therefore, next odd number is 7x + 2.
Hence, this is the required solution.
Answer:
y-intercept = (0, - 3)
x-intercept = (-6, 0)
slope = - 1/2
Step-by-step explanation:
The y intercept is the value of y when the x = 0. By looking at the graph, we can tell that when x = 0, y = - 3. Likewise for the x-intercept.
We can use the slope formula to determine the slope.
m = y2 - y1/ x2 - x1
You can choose any 2 points on the line and substitute in the formula. I chose the y and x intercepts for easier calculations.
m = - 3 - 0/ 0 - (- 6)
m = - 3/ 6
m = - 1/2
Answer:
what math is this
Step-by-step explanation:
In this question it is already given that a person travels 8 miles in 0.5 hours. This is enough information to get to the required answer. Let us first write down all the information's that are already given in the question.
In 0.5 hours the person covers a distance = 8 miles
Then
In 1 hour the person covers a distance of = 8/0.5 miles
= 16 miles
So the speed of the person in miles per hour = 16/1 miles/hour
= 16 miles per hour
