The ancestors to the equation is c=20
Answer:
Step-by-step explanation:
3u=y/x^2-d^2
3u=y-(xd)^2/x^2
u=y-(xd)^2/3x^2
To solve this you must replace x with -4 and y with 5 in the equation 7x + y² like so:
7 × (-4) + 5²
To solve this use PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)
REMEMBER: IF NOT APPLICABLE TO THE EQUATION YOU MAY SKIP THAT STEP IN PEMDAS .
Exponent...
7 × (-4) + 5²
5² = 5 × 5 = 25
7 × (-4) + 25
Multiplication...
7 × (-4) + 25
7 × (-4) = -28
-28 + 25
Addition...
When adding a positive number with a negative number you will act as if you are subtracting the two numbers, then take the sign of the largest number (disregarding the signs). In this case the largest number is 28 and its sign is negative. Your answer will have a negative sign.
-28 + 25 = -3
-3

Answer:
a) yes
b) no
c) no
Step-by-step explanation:
a) The percentage change from 12 to 15 is ...
(15/12 -1)·100% = 1/4·100% = 25% . . . . between 20% and 30%
__
b) The height increased by 61-52 = 9 inches. 20% of 52 inches is 10.4 inches, so the increase was less than 20%.
__
c) The increase was negative, so was not between two positive values.
___
In summary ...
a) yes, 25% is between 20% and 30%
b) no, 17.3% is NOT between 20% and 30%
c) no, -33.3% is NOT between 20% and 30%
_____
A percentage change can be calculated from ...
((new value)/(old value) -1) × 100%
