Answer:
4
Step-by-step explanation:
-2x- 4 + 5x = 8
Collect like terms
-2x + 5x = 8 +4( when a variable crosses over equality sign it becomes either negative or positive depending on the sign)
3x = 12
Divide via by coefficient of x
X = 12/3
= 4
Slope= ((-4)-1)/(2-(-3))
= -1
equation
y=mx
y=(-1) x
y=-x
Answer:
90 days.
Step-by-step explanation:
dy/dt = - 0.0032y
dy = -0.0032y dt
dy/y = -0.0032 dt
Integrating:
ln y = -0.0032t + c where c is some constant
y = e^(-0032t) + e^c
y = A e^(-0032t) where A is a constant.
At time 0 we can let y = 1 so in that case A = 1
When there is 0.75 of y left:
0.75 = e^-0032t
ln 0,75 = -0032 t
t = ln 0.75 / -0032
t = 90.
Answer:
7/12 of the students
Step-by-step explanation:
So first you would need to get your fractions to have the same denominator. When your trying to get your fractions to get the same denominato. You must multiply both the numerator and denominator.
The most common denominator from 1/4 and 1/3 is 12. So you multiply both the numerator and denominator of 1/4 by 3. So then your new fraction is 3/12. Now you multiply 1/3, both numerator and your denominator by 4. Then your new fraction is 4/12. So The last step is to add both of your numerators. Never add the denominators together. And at last you have your answer. 7/12.

Ok name the expressions we both know 3z is one 5x is one 6xy is one do you think 3x^2y^4z is an expression i would give you the answer but i also want you to understand the problem and what your looking for to in the equation
