Well, if y = x - 5, then we calculate:
when x = -1 then y = -1 -5 = -6
when x = 0 then y = -5
when x = 1 then y = 1 - 5 = -4
when x = 2 then y = 2 - 5 = -3
Hope this helps!
Answer:
If light passes in an angle to a surface with a particular refractive index it refracts. This change in direction is due to a change in velocity. As light , for example, travels from air through water, it slows down, allowing it to continue travelling at a different angle or direction.
Step-by-step explanation:
Angle ABC is an inscribed angle so would be half of the arc.
So, 4x-5.5=1/2(5x+25)
4x-5.5=5/2x+25/2
4x-5.5=2.5x+12.5
4x-2.5x=12.5+5.5
1.5x=18
x=12
So angle ABC=4(12)-5.5=48-5.5=42.5
Arc AC=5(12)+25=60+25=85
Check: 42.5(2)=85
Answer: Arc AC is 85
Answer: He can mow 4 lawns before he needs to buy more gasoline.
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
- <em>Gallons of gasoline available: 2/3
</em>
- <em>Gallons of gasoline used for mow a lawn: 1/6
</em>
So, to find the number of lawn that he can mow, we have to divide the gasoline available (2/3) by the amount used for mow a single lawn (1/6)
Mathematically speaking:
2/3 ÷1/6 = (2x6) / (3x1) = 12/3=4
He can mow 4 lawns before he needs to buy more gasoline.
N=18
Add 8 to both sides of the equation so you get n/3 = 6
Multiply 6•3 = n
n=18
