Answer:

x=7/2, y=3

Step-by-step explanation:

3x-2(10-2x)=22

3x-20+4x=22

7x=2

x=7/2

y=10-2(7/2)

y=3

Answer:

x=6\\\\y=-2

Step-by-step explanation:

y=10-2x    Equation:1

3x-2y=22  Equation:2

Using Substitution method:

Putting Equation:1 in Equation :2

3x-2(10-2x)=22\\\\3x-2(10)-2(-2x)=22\\\\3x-20+4x=22\\\\

Adding the like terms:

7x-20=22\\\\

Adding '20' both the sides:

7x=22+20

7x=42\\

Dividing by '7' both sides;

x=\dfrac{42}{7} \\\\x=6

Putting  the value of 'x' in Equation :1

y=10-2x

y=10-2(6)\\\\y=10-12\\\\y=-2

x=6\\\\y=-2

Which properties are present in a table that represents an exponential function in the form y-b* when b > 1?
erastovalidia [21]

Answer:

<u>Properties that are present are </u>

Property I

Property IV

Step-by-step explanation:

The function given is  y=b^x  where b > 1

Let's take a function, for example,  y=2^x

Let's check the conditions:

I. As the x-values increase, the y-values increase.

Let's put some values:

y = 2 ^ 1

y = 2

and

y = 2 ^ 2

y = 4

So this is TRUE.

II. The point (1,0) exists in the table.

Let's put 1 into x and see if it gives us 0

y = 2 ^ 1

y = 2

So this is FALSE.

III. As the x-value increase, the y-value decrease.

We have already seen that as x increase, y also increase in part I.

So this is FALSE.

IV. as the x value decrease the y values decrease approaching a singular value.

THe exponential function of this form NEVER goes to 0 and is NEVER negative. So as x decreases, y also decrease and approached a value (that is 0) but never becomes 0.

This is TRUE.

Option I and Option IV are true.

two men A and B stand on opposite sides of a 100 metre tower.A observes the angle of elevation of the top of the tower as 45 and
Zepler [3.9K]

9514 1404 393

Answer:

  273 m

Step-by-step explanation:

The tower represents the short side of a 30°-60°-90° right triangle. The distance from the tower represents the long leg, not the hypotenuse, of that triangle. It is √3 times the short side. In this geometry, man B is 100√3 = 173.2 meters from the tower.

The tower represents one of two congruent sides of a 45°-45°-90° right triangle. Man A will be standing 100 meters from the tower.

The distance between A and B is 100 +173.2 = 273.2 meters. The men are about 273 meters apart.
