Answer:
C. -21 is your answer
Step-by-step explanation:
Solve for t. Isolate the variable t in the first equation, then use the number gotten to solve the second equation.
3t - 7 = 5t
First, subtract 3t from both sides
3t (-3t) - 7 = 5t (-3t)
-7 = 5t - 3t
-7 = 2t
Isolate the variable (t). Divide 2 from both sides
(-7)/2 = (2t)/2
t = -7/2
t = -3.5
Plug in -3.5 for t in the second equation
6(t) = 
6(-3.5) = 
6(-3.5) = -21
C. -21 is your answer

Answer:
2/10
Step-by-step explanation:
Im pretty sure its 2/10 
have a great day:)
 
        
             
        
        
        
A linear equation can be represented by: 
y = mx + b 
Where m = slope, and b = y intercept. 
The slope is a rate of change, so our slope is $150. 
The y intercept is the point where the equation crosses the y axis, or the "initial amount" in this case $500. 
So our equation will be: 
y = 150x + 500. 
        
             
        
        
        
A. First move all to the left side of the equation(Normal form)
x^3 - 49x= 0
B. Factor out an x, which is the GCF (Factored form)
x(x^2 - 49) = 0
C. Find solutions by making each x piece equal to 0. The first part is just x=0 and the second part is just factoring the difference of squares and then solving.
 x=0, x^2 - 49 =0
x=0, x + 7 = 0, x - 7 = 0
 Therefore, the answers for Part C are:
x = 0, x = -7, x = 7
