Snezhnost [94]

Answer:

A) ≈ 6.93

B) ≈ 0.02

Step-by-step explanation:

A)

Formula : a² + b² = c²

2.4² + 6.5² = c²

5.76 + 42.25 = c²

c = √48.01

c ≈ 6.93

B)

Formula = c² - a² = b²

1/3² - 1/4² = b²

1/9 - 1/16 = b²

b = √7/144

b ≈ 0.02

How to tell if its identifying functions is <br> a function or not
Svetach [21]

Answer:

Step-by-step explanation:

Determining whether a relation is a function on a graph is relatively easy by using the vertical line test. If a vertical line crosses the relation on the graph only once in all locations, the relation is a function. However, if a vertical line crosses the relation more than once, the relation is not a function.

EXPLAIN WHY THE SYSTEM HAS THE ANSWER GIVEN. SOLVE EACH SYSTEM BY ELIMINATION TO PROVE YOUR ANSWER.
Aleonysh [2.5K]

Answer:

Step-by-step explanation:

The given system of equations is expressed as

3x + y = 9 - - - - - - - - - - - - - - -1

3x = 9 - y - - - - - - - - - - - - - -2

To apply the method of elimination, we would rearrange equation 2 so that it would take the form of equation 1. Therefore, we would add y to the left hand side and the right hand side of the equation, it becomes

3x + y = 9 - - - - - - - - - - - - - - - - -3

Subtracting equation 3 from equation 1, it becomes

0 = 0

The equations have infinitely many solutions because if we input any values of x and y that satisfies the first equation, those values will also satisfy the second equation.
