Evaluate each expression for s=4 and t=8 1) (25)^2t 2) 2st^2-5^2 3) 2s^2-t^3/16

stepladder [879]

Answer:

1. 2.328× $10^{22}$

2. 487

3. 30.52 OR 0 (see explanation↓)

Step-by-step explanation:

1. $(25)^{2t}$

(sub for t=8)

= $25^{2*8}$

= $25^{16}$

=2.328× $10^{22}$

2. $2st^{2} -5^{2}$

(sub for s=4 and t=8)

=2×4× $8^{2}$ - $5^{2}$

=512-25

=487

3. $2s^{2} -t^{3/16}$ (the equation is not clear so I will do $2s^{2} -\frac{t^{3} }{16}$ as well)

FOR $2s^{2} -t^{3/16}$

(sub s=4 and t=8)

=2× $4^{2}$ - $8^{3/16}$

=32-1.476826146

=30.52 (to the nearest 2 decimal place)

FOR $2s^{2} -\frac{t^{3} }{16}$

(sub s=4 and t=8)

=2× $4^{2}$ - $\frac{8^{3} }{16}$

=32-32

Solve using either substitution or elimination X-3Y=-14 X-Y=-2

Paraphin [41]

Answer: (4,6)

Explanation:

x - 3y = -14
x - y = -2

Multiply a -1 to the first equation so the x’s can cancel out.

-x + 3y = 14
x - y = -2

Subtract the two equations together.

2y = 12

y=6

Now, plug in y to one of the original equations.

x - (6) = -2

x=4

Therefore, the answer is: (4,6)
