Answer:
∠4 = 100°
Step-by-step explanation:
This has nothing to do with parallel lines.
Angles 1 and 4 are "vertical angles", hence congruent.
∠1 = ∠4 = 100°
_____
Vertical angles are on opposites sides of the intersection where lines cross.
Y=mx+b
so is 2
the last number of the equation
A fraction equivalent to 9/15 is 3/5
To find equivalent fractions, you have to find a a divisor that both the numerator and denominator has. Then you divide the numerator and denominator by that divisor.
Example: 9 and 15 are divisible by 3.
9 is the numerator.9 divided by 3 is 3. so the numerator of the equivalent fraction is now 3.
15 is the denominator. 15 divided by 3 is 5. the denominator is now five.
Hope this helps! :)
F(x) = 20x+300
you sub in the x values (120 hours and 100 hours) for each equation
the only one they both work for is the last one
f(x) = 20x + 300
f(100) = (20 * 100) + 300 = 2000 + 300 = 2300
f(120) = (20 * 120) + 300 = 2400 + 300 = 2700
3x-12 ≥7x+4
Subtract 3x from both sides
-12 ≥4x+4
Subtract 4 from both sides
-16 ≥4x
Divide each side by 4
-4 ≥x
From point 4, you use a closed circle and the arrow is facing towards 0
