Answer:
4x + x + 7) - 2x+8 - 4 by substituting x= 1 and x = 2. А. 6x + 11 B. 3(x+7) C. 2(3x + 16) D. 3x + 16
Step-by-step explanation:
Answer:-2/5
Step-by-step explanation:
Now the above equation can be rewritten as 5y= -2x+1
Dividing this expression through by 5, we have 5y/5 = -2x/5 + 1/5
y= (-2/5)x + 1/5
Comparing with the general equation of a line;
y = mx + c; m= gradient; C= constant along the y-axis
m= -2/5
Answer:
4
Step-by-step explanation:
A.) f(x) = x^2 because 2 > 1. So f(2) = 4.
A is correct.
B.) f(x) = x^2 because 5 > 1. So f(5) = 25.
B is incorrect.
C.) f(x) = 2x because -2 < 1. So f(-2) = -4.
C is incorrect.
D.) f(x) = 5 because x = 1.
D is correct.
So the answer is A and D.
Answer:
(n-m)/m * 100%
Step-by-step explanation:
The original amount is m
The new amount is n
Take the new amount and subtract the original amount
(n-m)
Divide by the original amount
(n-m)/m
Multiply by 100 %
(n-m)/m * 100%
