can you guys please help me on my homework? It would mean a lot to me :)

Answer:

[tex]\left \{ {{x=0} \atop {y=2}} \right.[/tex]

Step-by-step explanation: [tex]\left \{ {{4x-y=-2} \atop {2x+y=2}} \right.[/tex]

Add the two equations

[tex]4x-y+(2x+y)=-2+2[/tex]

Remove parentheses

[tex]4x-y+2x+y=-2+2[/tex]

Cancel one variable

[tex]4x+2x=-2+2[/tex]

Apply the Inverse Property of Addition

[tex]4x+2x=0[/tex]

Combine like terms

[tex]6x=0[/tex]

Divide both sides by the equation by the coefficient of variable

[tex]x=0[/tex]

Substitute into one of the equations

[tex]2\times0+y=2[/tex]

Apply Zero Property of Multiplication

[tex]y=2[/tex]

The solution of the system is

[tex]\left \{ {{x=0} \atop {y=2}} \right.[/tex]

Answer:

-103

Step-by-step explanation:

Exponentiation: 2 ^ 2 = 4

Add: the result of step No. 3 + 7 = -4 + 7 = 3

Exponentiation: 5 ^ 3 = 125

Subtract: the result of step No. 5 - 2 = 125 - 2 = 123

Exponentiation: 3 ^ 2 = 9

Subtract: the result of step No. 6 - the result of step No. 7 = 123 - 9 = 114

Subtract: the result of step No. 8 - 8 = 114 - 8 = 106

Subtract: the result of step No. 4 - the result of step No. 9 = 3 - 106 = -103

Answer:

Step-by-step explanation:

To solve this equations, we must use the order of operations, or PEMDAS, Parenthesis, exponents, multiplication, division, addition, and subtraction.

The value of the first side is 30, the value of the second side is -106

We add and subtract and our answer will be -76

Answer:

[tex]\displaystyle y = [x - 3]^2 + 6[/tex]

Step-by-step explanation:

Use the method called complete the square, but in this case, we need to take half of the B-term and square the result afterward. Here is how it is done:

[tex]\displaystyle [\frac{b}{2}]^2 \hookrightarrow [\frac{-6}{2}]^2; 9 \\ \\ \boxed{[x - 3]^2} \hookrightarrow x^2 - 6x + 9[/tex]

Now, after you get an equation from using this method, you must follow ONE MORE PROCEDURE, which is figuring the quantity out that when added to 9, you get 15, and that will be 6. So, with that, you have your vertex equation:

[tex]\displaystyle y = A[x - h]^2 + k \\ \\ \boxed{\boxed{y = [x - 3]^2 + 6}}[/tex]

**In the event you have a quadratic equation, if you are asked to locate the vertex, IF factourable, convert the quadratic equation to a vertex equation, where [tex]\displaystyle [h, k][/tex]represents the vertex:

[tex]\displaystyle y = Ax^2 + Bx + C \hookrightarrow y = A[x - h]^2 + k[/tex]

I am delighted to assist you at any time.

Answer:

12 meters to the left, or -12

Step-by-step explanation:

3 meters per second for 4 seconds

Meaning it's 3 x 4

3 x 4 = 12, so therefore it's -12 meters or just 12 meters to the left.

Answer:

12 meters to the left of your starting point.

Step-by-step explanation:

You start at 0 meters. You then start running to the left with an acceleration of 3 m/s to the left. After each seconds, you are 3 more meters to the left.

So

3 m/s * 4 s = 12 m to the left.

Hence, the answer in 12 meters to the left.

Answer:

Step-by-step explanation:

since X is the midpoint of PQ , then

PX = QX ( substitute values )

4x + 15 = 7x + 6 ( subtract 4x from both sides )

15 = 3x + 6 ( subtract 6 from both sides )

9 = 3x ( divide both sides by 3 )

3 = x

Then

PX = 4x + 15 = 4(3) + 15 = 12 + 15 = 27

XQ = 7x + 6 = 7(3) + 6 = 21 + 6 = 27

PQ = PX + XQ = 27 + 27 = 54

Answer:

PX = 4x + 15 = 4(3) + 15 = 12 + 15 = 27

XQ = 7x + 6 = 7(3) + 6 = 21 + 6 = 27

PQ = PX + XQ = 27 + 27 = 54

Step-by-step explanation:

Since X is the midpoint of PQ , then

PX = QX ( substitute values )

4x + 15 = 7x + 6 ( subtract 4x from both sides )

15 = 3x + 6 ( subtract 6 from both sides )

9 = 3x ( divide both sides by 3 )

3 = x

Then

PX = 4x + 15 = 4(3) + 15 = 12 + 15 = 27

XQ = 7x + 6 = 7(3) + 6 = 21 + 6 = 27

PQ = PX + XQ = 27 + 27 = 54

Hence, the correct answers are: PX = 4x + 15 = 4(3) + 15 = 12 + 15 = 27

XQ = 7x + 6 = 7(3) + 6 = 21 + 6 = 27 PQ = PX + XQ = 27 + 27 = 54

Solution:

We know that the diameter of the semi-circle is 30 inches. Before we use the formula, let's find the radius of the semi-circle.

⇒ Diameter = 2(Radius)

⇒ 30 inches = 2(Radius)

⇒ Radius = 30/2 = 15 inches

The area of the circle is πr², but we need to find the area of the semi-circle. A semi-circle is basically half of a circle. This means that the area of a semi-circle is πr²/2. Now, let's solve for the area of the semi-circle.

⇒ πr²/2 = Area of semi-circle

⇒ (22/7)(15²)/2

⇒ (22/7)(225)/2

⇒ (22/7)(112.5)

⇒ 22/7 × 112.5

⇒ 2475/7 in²

Thus, the area of the semi-circle is 2475/7 in².

Answer:

a. Total field goal points scored in the first two quarters, in simplest linear expression form is: 3x - 4.

b. The total points scored in the game, in simplest linear expression form is: 6x - 1.

a. The goal points scored in the first two quarters are expressed in linear forms as: 2x - 6 and x + 2.

The total field goal points in the first two quarters = 2x - 6 + x + 2

Add like terms

3x - 4

b. The total points scored in the game = 2x - 6 + x + 2 + 2x + x - 6 + 9

Add like terms and simplify the expression

Answer: x = 5/2 or 2.5

Step-by-step explanation:

1/4x = 5/8

To find the value of X;

We multiply both sides by 4

1/4 x × 4 = 5/8 × 4

x = 5/2 or 2.5

Hey there!

1/4x = -5/8

MULTIPLY 4/1 to BOTH SIDES

4/1 * 1/4x = -5/8 * 4/1

CANCEL out: 4/1 * 1/4 because it give you 1

KEEP: -5/8 * 4/1 because it give you the x-value

NEW EQUATION: x = -5/8 * 4/1

SIMPLIFY IT!

x = -5/2

Therefore, your answer is: x = -5/2

Answer: 262.50  is 8.75% of 3000

Step-by-step explanation:

Solution for 262.50 is what percent of 3000:

262.50:3000*100 =

(262.50*100):3000 =

26250:3000 = 8.75

Now we have: 262.50 is what percent of 3000 = 8.75

Question: 262.50 is what percent of 3000?

Percentage solution with steps:

Step 1: We make the assumption that 3000 is 100% since it is our output value.

Step 2: We next represent the value we seek with  x


Step 3: From step 1, it follows that 100% = 3000.


Step 4: In the same vein, x% = 262.50 .

Step 5: This gives us a pair of simple equations:

100% = 3000(1).

x% = 262.50(2).

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

100%/x% = 262.50%/3000

x = 8.75% Therefore, 262.50  is 8.75% of 3000
