<span>3/5t - 4 - 7/10t = -2
</span><span>3/5t - 7/10t = -2 + 4
</span><span>6/10t - 7/10t = 2
-1/10t = 2
t =2 (-10)
t = -20
answer is </span>A. -20
The solution of the given equations is: (-1.5, 1.5)
Step-by-step explanation:
Linear equation usually represents a straight line. When a system of two liner equations is given, the point of intersection of lines represented by both equations is the solution of the system of equations.
We will plot the lines of both equations and find their point of intersection (Picture Attached)
We can see in the picture that two lines intersect at (-1.5, 1.5)
Hence,
The solution of the given equations is: (-1.5, 1.5)

7^8*7=
5764801 * 7= 40353607
A. 7^3*7^3= 343*343= 117649 <--- not the answer
B. 7^18/7^9= 40353607 <---- right answer
C. (7^3)^3= 343^3= 40353607 <------ right answer
D. 7^5+7^4= 16807+2401= 19208 <---- not the answer
E. 7^5*7^4= 16807*2401= 40353607 <---- right answer
Answer:
Step-by-step explanation:
Hello, first of all we can find a value for f(1)
And we can get the derivative of the equation so.
Thank you
Y = 250 + 100x....the slope is 100
it represents the per second fee of air time...basically, it costs $ 100 per second for the commercial....wow...100 bucks per second....that radio station is making some money.
