Answer:
y = 4/3x + 4
Step-by-step explanation:
y = mx + b is the formula for finding the slope intercept form equation
m = slope
b = y intercept
If you look at points (-3, 0) and (0, 4), you can calculate the slope
You have to go over, from point (-3, 0), 3 times, and up four to get to the point (0, 4)
Slope is change in y over change in x, so, if we look to see where the line crosses the y-axis, or vertical axis, we can see it reach the number four on the y-axis, b = 4
Now, lets create your equation...
y = 4/3x + 4
To calculate this you need to imagine triangle which points are:
boat
Top of lighthouse
Bottom of lighthouse
That triangle has 90 degrees angle at bottom of lighthouse. That means that we can use trigonometry to determine length between boat and bottom of lighthouse
tan(25) = 89/x
x = 89/tan(25)
x = 190.86
after rounding, the answer is D, 191 feet
Answer:
16
Step-by-step explanation:
8/2(2+2)
- According to the rules of BEDMAS, solve the values inside the bracket.
8/2 (4)
- Simplify the fraction outside the bracket.
4(4)
- Multiply the two values.
= 16
Answer:
(look at this equation) y=3x+2
Step-by-step explanation:
1. 2y-6x=4
2. Add -6x over to the other side
3. Subtract 2 from both sides
4. Look and see which points according to the equation that I answered for you.
