Answer:

no solution

Step-by-step explanation:

Given the 2 equations

y = $\frac{1}{2}$ x + 4 → (1)

- $\frac{1}{2}$ x + y = - 5 → (2)

Substitute y = $\frac{1}{2}$ x + 4 into (2)

- $\frac{1}{2}$ x + $\frac{1}{2}$ x + 4 = - 5 , that is

4 = - 5 ← not possible

This indicates the system has no solution

How do I solve this problem? You drive your car on a cold day (20^oF Outside) the engine overheats to about (220^oF). When you p

GaryK [48]

$ln(T- \frac{20}{200})=-0.11t \\ e^{ln(T- \frac{20}{200})}=e^{-0.11t} \\ T- \frac{20}{200} =e^{-0.11t} \\ T-0.1=e^{-0.11t} \\ T=e^{-0.11t}+0.1$
Then, now that we have solved for T, we can evaluate and solve for t=20 minutes.
$T=e^{-0.11t}+0.1 \\ T=e^{-0.11*20}+0.1 \\ T=e^{-2.2}+0.1 \\ T=0.11+0.1 \\ T=0.21$

-2x + y = 5 what does y equal and how did you solve it?

Olin [163]

Answer:

y=2x+5

Step-by-step explanation:

Let's solve for y.

−2x+y=5

Step 1: Add 2x to both sides.

−2x+y+2x=5+2x

y=2x+5
