Answer:
Step-by-step explanation:
The x intercept is the value of x when y = 0. Use the equation to find the value of x:
y= -1x + 3
0 = -1x + 3
x = 3
The point is (3,0)

Answer:
92 inches
Step-by-step explanation:
When a tire's size = P220/65 R 18, it means that:
- the rim is 18 inches wide (or 457 millimeters)
- the width of the tire is 8.7 inches (or 220 millimeters)
- the sidewall of the tire is 5.65 inches (or 144 millimeters)
- the 65 shows the relationship between tire width and sidewall (65%)
the total diameter of the tire = 5.65 + 18 + 5.65 = 29.3 inches
the circumference = 2 x π x radius or diameter x π = 29.3 x 3.141592 = 92 inches
Answer:
The initial height of the balloon is 2 feet.
Step-by-step explanation:
The height of the balloon in feet after t seconds is given by the following equation:
What is the initial height of the balloon?
This is h when t = 0, that is, h(0). So
The initial height of the balloon is 2 feet.
First things first, you will have 94 + x. Place those on top of a fraction bar and on the bottom put the two numbers over 2. So you have 94 + x over 2. Then, write the symbol ‘greater than or equal to’ and on the other side place your 90. So, 90 + x over 2 is greater than or equal to 90. This is a difficult thing to write out and explain so I hope this makes sense. :)
