Answer:
4 =x
Step-by-step explanation:
-3(x+4) = 4(x-10)
Distribute
-3x-12 = 4x - 40
Add 3x to each side
-3x -12 +3x = 4x +3x-40
-12 = 7x-40
Add 40 to each side
-12 +40 = 7x - 40+40
28 = 7x
Divide each side by 7
28/7 = 7x/7
4 =x
In mathematics, a ratio is a relationship between two numbers indicating how many times the first number contains the second. For example, if a bowl of fruit contains eight oranges and six lemons, then the ratio of oranges to lemons is eight to six (that is, 8:6, which is equivalent to the ratio 4:3). Thus, a ratio can be a fraction as opposed to a whole number.The ratio for 12:8 is 6:4
Answer:
C. 17
Step-by-step explanation:
I'm assuming you need the hypotenuse so to get that you do
The square root of a^2 + b^2
a squared + b squared
So it becomes square root of 8^2 + 15^2
= square root of 64 + 225
= square root of 289
= 17

The value that is equal to the average rate of change of the function over the interval is equal is 1 m/s
<h3>The average rate of change</h3>
Given the position of the object expressed as:
y = -t^2 + 3t - 4
In order to calculate the value that is equal to the average rate of change of the function over the interval (0, -4) and (2, -2), we will determine the slope of these two coordinates as shown;
Rate of change = -2-(-4)/2-0
Rate of change = -2+4/2
Rate of change = 2/2
Rate of change = 1 m/s
Hence the value that is equal to the average rate of change of the function over the interval is equal is 1 m/s
