I think the answer is option c.one
there is only one sign change in the whole equation so possiblythe answe must be one. correct me if i am wrong
Answer:
a) An input of 5 gives an output of 14. An input of -1 gives an output of -4.
An input of x gives an output of 3x - 1
b) y = 3x - 1
Step-by-step explanation:
The pattern is that you multiply the number by 3 then subtract 1.
3*3 - 1 = 9 - 1 = 8
10 * 3 - 1 = 30 - 1 = 29
20 * 3 - 1 = 60 - 1 = 59
So:
a)
For an input of 5,
5 * 3 - 1 = 15 - 1 = 14
For an input of -1:
-1 * 3 - 1 = -3 - 1 = -4
For an input of x:
x * 3 - 1 = 3x - 1
So the equation is
b) y = 3x - 1
where x is the input value.
Answer:
10^x
Step-by-step explanation:
√2^x×5^2x÷2^-x
√2^x×5^2x×2^x
√10^2x
10^x
Answer:
Option 3
Step-by-step explanation:
=> 5(3c-3)+6(c-2)
Expanding the expression
=> 15c-15+6c-12
Combining like terms
=> 15c+6c-15-12
=> 21c-27
Given:
Length of the rectangle = x + 21
Width of the rectangle = 5
To find:
Perimeter and area of the rectangle
Solution:
Perimeter =
Perimeter units
Area = length × width
Area square units
Substitute perimeter is 100 and find the value of x:
Subtract 52 from both sides.
Divide by 2 on both sides, we get
x = 24
Substitute area is 200 and find the value of x:
Subtract 105 from both sides.
Divide by 5 on both sides, we get
x = 19
If the perimeter is 100, then the value of x is 24.
If the area is 200, then the value of x is 19.
