x=7 because if you replace x with 7 then 4 times 7 is 28 and 28 minus 6 is 22
A unit rate compares a quantity to one unit of measure. You often see the speed at which an object is traveling in terms of its unit rate.
A number line is a line that extends infinitely in both directions (marked by arrows) that shows a range of numbers with a consistent distance between increments.
- Draw a line
- Draw arrows on both sides pointing out
- Write the minimum and maximum values on the left and right side repectively
- Add appropriate increments with equal distances on the number line
Answer:
50°
Step-by-step explanation:

Answer with Step-by-step explanation:
We are given that
u+ v and u-v are orthogonal
We have to prove that u and v must have the same length.
When two vector a and b are orthogonal then

By using the property

We know that



Magnitude is always positive
When power of base on both sides are equal then base will be equal
Therefore,

Hence, the length of vectors u and v must have the same length.
