Answer:
Step-by-step explanation:
Taking the base 2 log of both sides, we get:
log-base 2 of 2 + log-base 2 of y = log-base 2 of 5, or
2 + log-base 2 of y = approx. 2.3, or
log-base 2 of y = approx 2.3 - 2, or
log-base 2 of y = approx 0.3

Step-by-step explanation:
<u>Step 1: Define equation</u>
3(x - 2) = 2(x + 1)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute: 3x - 6 = 2x + 2
- Subtract 2x on both sides: x - 6 = 2
- Add 6 to both sides: x = 8
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: 3(8 - 2) = 2(8 + 1)
- Subtract/Add: 3(6) = 2(9)
- Multiply: 18 = 18
Here we see that 18 does indeed equal 18.
∴ x = 8 is a solution to the equation.
Answer:
-4
Step-by-step explanation:
<em>Hey there!</em>
<em />
Well the slopes of 2 parallel lines have the same slope,
meaning if the green line has a slope of -4 then the slope of the red line has a slope of -4.
<em>Hope this helps :)</em>
Step-by-step explanation:
if you're looking for x
x=180-42-51= 87°
and if you're looking for D
D= 180-42= 138°
