Answer:
f(x)= -7x+7
Step-by-step explanation:
7 is length and 5 is width. Hope this helped!!
Reshma's age = x
Reshma = x + 5
Reshma's father= 3x + 5
x + 5 + 3x + 5 = 70
4x + 10 = 70
4 x = 60
x = 15
So Reshma's age currently is 15 and 3(15), which is 45, is her father's age.
Answer:
The screenshot shows the correct answers; 5x + 5y = 25 is linear.
For a equation to be linear:
- The equation should not have square root, cube root, etc.
- The value of x is not greater than one. X should not have an exponent.
- X is not in a denominator of a fraction.
- "xy" should not be in the equation.
