Answer:
t = 4.5
Step-by-step explanation:
1.8 = 0.4(t) solve for t
We start by finding the intercept of the line: what does y equal when x=0? and what does x equal when y=0?
• intercept in x
y = 12 + 2x
0 = 12 + 2x
-12 = 2x
-6 = x
• intercept in y
y = 12 + 2x
y = 12 + 2(0)
y = 12 + 0
y = 12
Now we find three more points giving y a value and finding x
y = 12 + 2x
2 = 12 + 2x
2-12 = 2x
-10 = 2x
-5 = x
y = 12 + 2x
6 = 12 + 2x
6 - 12 = 2x
-6 = 2x
-3 = x
y = 12 + 2x
14 = 12 + 2x
14 - 12 = 2x
2 = 2x
1 = x
Notice how I gave y even numbers as values since we would have to divide with 2 at the end.
Sol. {(-6,0)(0,12)(-5,2)(-3,6)(1,14)}
Okay, 72 degrees is equal to (5x-98), so
72=5x-98
5x=170
x=34
So now that we know that x=34, we can put 34 into (5x-98), so 170-98
170-98 and y are supplementary, so they add up to 180 degrees. So the equation is
170-98+y=180
72+y=180
y=180-72
y=108
Answer: C
all shapes must equal 360 degrees
90 x the 4 angles of the square equals 360 degrees
