Answer:
sqrt(65)
Step-by-step explanation:
|a+bi|
The absolute value of |a+bi| = sqrt(a^2+b^2)
|4+7i| = sqrt(4^2+7^2) = sqrt(16+49) = sqrt(65)
The answer is D) 5 and 5/8ths because 2 1/2 + 3 3/4 + 4 1/8
= 10 3/8
10 3/8 + 5 5/8 = 16
Answer: y=-.667x+1
Step-by-step explanation:
1. Firstly, substitute the coordinates of the two points into the slope intercept equation:
(1) y₁ = mx₁ + b
(2) y₂ = mx₂ + b
2. Then, subtract the first equation from the second:
y₂ - y₁ = m(x₂ - x₁)
3. Finally, divide both sides of the equation by (x₂ - x₁) to find the slope:
m = (y₂ - y₁)/(x₂ - x₁)
4. Once you have found the slope, you can substitute it into the first or second equation to find the y-intercept:
y₁ = x₁(y₂ - y₁)/(x₂ - x₁) + b
b = y₁ - x₁(y₂ - y₁)/(x₂ - x₁)
So the goal here is to find the value of "w". The first thing you must do is transpose the number 9 to the side of -7 and it would look like this, 4w = -7 - 9. Change the positive sign of the number 9 to negative when you transpose. Then, the equation will be simplified and it will look like this, 4w = -16. Then lastly, to get the value of "w", you must divide the equation to 4 and it will be like this,
<u>4w</u> = <u>-16 </u> so you will get the answer w = -4. I hope this helps you<u>

Answer:
96%
Step-by-step explanation:
Take the amount spent of fruit and divide by the total
48/50
Percent means out of 100 so multiply the top and bottom by 2
96/100
96%
