What is this math problem?
3x = 6y - 21
6x - 9y = -30

Answers

Answer 1

Answer 1: x=2y−7

Answer 2: x= 3/2y -5

Heart if this helped

Answer 2

Answer:

x=1 and y=4

Step-by-step explanation:

Let's solve your system by substitution.

3x−6y=−21;6x−9y=−30

Step: Solve3x−6y=−21for x:

3x−6y=−21

3x−6y+6y=−21+6y(Add 6y to both sides)

3x=6y−21

x=2y−7

Substitute2y−7for x in6x−9y=−30:

6x−9y=−30

6(2y−7)−9y=−30

3y−42=−30(Simplify both sides of the equation)

3y−42+42=−30+42(Add 42 to both sides)

3y=12

y= 4

Substitute4foryinx=2y−7:

x=2y−7

x=(2)(4)−7

x=1(Simplify both sides of the equation)

What fraction describes the probability for two coins being tossed at the same time to both land on heads?

3/4
1/4
1/2

Answers

Answer: 1/4

Step-by-step explanation:

A coin has two outcomes which are either the head or the tail. When a coin is tossed, the probability of getting a head is 1/2 and likewise for a tail.

Therefore, the probability for two coins being tossed at the same time to both land on heads will be:

= 1/2 × 1/2

= 1/4

Answer:

1/4

A tower has lost contact with a GPS satellite. The satellite is at 4500 meters over the Earth at a location 2000 meters from the tower. At what angle should the tower point and scan to make contact again? Note the height of the tower is not included. Round answers to the nearest whole degree.The angle of elevation from the top of the tower to the satellite is?

Answers

Answer:

66°

Step-by-step explanation:

It is given that :

Distance of the satellite from the tower = 2000 m

Height of the satellite above the tower = 4500 m

Therefore the angle of elevation can be found out by :

[tex]$\tan \theta = \frac{4500}{2000}$[/tex]

[tex]$\tan \theta = \frac{9}{4}$[/tex]

[tex]$\tan \theta = 2.25$[/tex]

[tex]$\theta = \tan^{-1}(2.25)$[/tex]

  [tex]$= 66 ^\circ$[/tex]

Therefore the tower can make contact with GPS satellite when it pointed at 66° angle.

Answers

Answer:

Option B

Step-by-step explanation:

Given function is,

p(x) = x²- (2√2)x + 1

We have to find the value of p(2√2).

By substituting the value x = 2√2

p(2√2) = (2√2)² - (2√2)(2√2) + 1

           = 8 - (2√2)² + 1

           = 9 - 8

           = 1

Therefore, Option B will be the correct option.

c
C. 11.45 cm2
180°
D. 16.96 cm2

Answers

Answer:

The correct answer is [tex]11.45 cm. ^2[/tex]

Step-by-step explanation:

I just got it correct.

The approximate area of the shaded sector in the circle shown is,

⇒ 11.45 cm²

What is mean by Circle?

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

We have to given that;

A circle is shown in figure with diameter 5.4 cm.

Hence, Radius of circle = 5.4 / 2 = 2.7 cm

Since, Area of circle = πr²

Hence, We get;

Area of circle = πr²

Area of circle = 3.14 × 2.7²

Area of circle = 22.89 cm²

Thus, Area of shaded region of the circle is,

⇒ 22.89 cm²

⇒ 22.89/2 cm²

⇒ 11.45 cm²

Thus, The approximate area of the shaded sector in the circle shown is,

⇒ 11.45 cm²
