Answer:

1) 4

2) y <= 9

3) NO SOLUTION

4) 24

5) 5 cards

Step-by-step explanation:

1st pic) 2x + 7 = 15

2x + 7 = 15

-7 -7

2x = 8

divide by 2 to isolate x

x = 4

2nd pic) y - 3 <= 6

y - 3 <= 6

+3 +3

y <= 9

3rd pic) x + 0.5 = x + 6

x + 0.5 = x + 6

-0.5 -0.5

x = x + 5.5

NO SOLUTION

4th pic) 5m + 10 <= 130

5m + 10 <= 130

-10 -10

5m <= 120

divide by 5 to isolate the m

m <= 24

5th pic) 2c - 8 > 0

2c - 8 > 0

+8 +8

2c > 8

divide by 2 to isolate the c

c > 4

Solve the system: x' = (2 4 -1 6)x

sertanlavr [38]

Answer:

$x=e^{8t}+c$

Step-by-step explanation:

we have given x'=(24-16)x=8x

x' denotes the differenation

$\frac{dx}{dt}=8x$ differentiation is performed with respect to t

by variable separable method we can write

$\frac{dx}{x}=8dt$

on integrating both side

$lnx=8t+c$

$x=e^{8t}+c$ (property of log )

so the solution for x will be $x=e^{8t}+c$
