Answer:
x=-7/9
Step-by-step explanation:
To solve this equation we would consider the bracket first according to BODMAS rule
B ..... Bracket open
O........ Of
D,............. Division
M............. Multiplication
A.............. Addition
S............. Subtraction
So, from the question
-3( x +3) = 3(x+1)-5
-3x -9 = 3x + 3 - 5
Collecting like terms
-3x -3x = 3-5+9
-9x= 7
Dividing both sides by -9
-9x/-9= 7/-9
x=-7/9
Answer:
The range for the function y=5-2x is all real numbers, but the numbers corresponding the the domain values of 0, 1, 2, and 3, are 5, 3, 1, -1.
Step-by-step explanation:
Answer:
cos A = 12/13
Step-by-step explanation:
TanC = AB/BC = 2.4
therefore
BC = AB/2.4
Pythagorean theorem
AC = √(AB² + (AB/2.4)²) = (13/12)AB
Cos A = AB/AC = AB / (13/12)AB = 12/13
Answer:
The hawk reaches the rabbit at t=4.3 sec
Step-by-step explanation:
Let
h ----> is the height in feet
t ----> is the time in seconds
v ---> the initial velocity in feet pr second
s ----- is the starting height
we have
when the hawk reaches the rabbit the value of h is equal to zero
we have
substitute
Solve the quadratic equation by graphing
The solution is t=4.3 sec
see the attached figure
So it is 18+7 which is 25 and you make the fraction out of the total books (50).
the fraction is 25/50 which is 0.50 as a decimal
