The answers are following
sol1 y = x-1
sol2 y= x+ 7
sol4 y = x+4
Step-by-step explanation:
Solution 1
Here we are going put the point in the given equation ( given in the options)
If the each point satisfies any equation, that will be the relationship between x and y.
Given points are (-3,-4) , (2,1) , (5,4)
Let us take the option C as y = x -1
-4 = -3-1
1 = 2-1
4=5-1
Putting each value in the given equation we get LHS and RHS are same for all points. so, C is the answer.
Similarly, option B is the answer of Solution 2
Each point satisfies the equation y = x +7
Solution 4
y = x +4
You are requested to check the options of Q3 once.
Answer:
The other side = 13 feets long
Step-by-step explanation:
Given that :
Scale of drawing : 2 inches represents 5 feets
Area of rectangular room according to scale drawing = 24.96 in²
Length of one side of the room = 12 feets
Length of other side = x
Area of rectangle = Length * width
If :
2 inches = 5 feets
x = 12 feets
x = (12 *2) / 5
x = 4.8 inches
Hence,
For the scaled drawing :
4.8 * width = 24.96
Width = 24.96 / 4.8
Width = 5.2 inches
Converting to feets according to scale:
2 inches = 5 feets
5.2 inches = x feets
x = (5.2 * 5 ) / 2
x = 13 feets
Other side is 13 feets long
Numbers are arranged by their place values. Place values give a quantity of value to a certain digit in a number. Given a number, the rightmost number is the ones place, followed by the tens place, hundreds, thousands, ten thousands, hundred thousands, millions, ten millions, hundred millions, as so on and so forth. The place value of a certain digit is 10 times bigger than its adjacent digit to the right.
So for this problem, all you have to do is multiply the number of units of each place value, then multiple them all by 10.
(2(10) + 1(1))×10
21 × 10 = 210
Therefore, the number is equivalent and written as 210.
