The Pythagorean Theorem states that a² + b² = c?, where a and b are legs of a
right triangle and c is the hypotenuse. Are you able to simplify the Pythagorean
Theorem further to say that a + b = c? Explain.

Answer:

The point (4,7) is a solution to the system of equations.

Please also check the attached graph.

Step-by-step explanation:

Given the system of equations

[tex]y=2x-1[/tex]

[tex]y=\frac{1}{2}x+5[/tex]

Let us solve the system of equations using the elimination method

[tex]\begin{bmatrix}y=2x-1\\ y=\frac{1}{2}x+5\end{bmatrix}[/tex]

Arrange equation variables for elimination

[tex]\begin{bmatrix}y-2x=-1\\ y-\frac{1}{2}x=5\end{bmatrix}[/tex]

subtracting the equations

[tex]y-\frac{1}{2}x=5[/tex]

[tex]-[/tex]

[tex]\underline{y-2x=-1}[/tex]

[tex]\frac{3}{2}x=6[/tex]

now solving [tex]\frac{3}{2}x=6[/tex] for x

[tex]\frac{3}{2}x=6[/tex]

Multiply both sides by 2

[tex]2\cdot \frac{3}{2}x=6\cdot \:2[/tex]

Simplify

[tex]3x=12[/tex]

Divide both sides by 3

[tex]\frac{3x}{3}=\frac{12}{3}[/tex]

Simplify

[tex]x=4[/tex]

For [tex]y-2x=-1[/tex] plug in x = 4

[tex]y-2\cdot \:4=-1[/tex]

[tex]y-8=-1[/tex]

Add 8 to both sides

[tex]y-8+8=-1+8[/tex]

Simplify

[tex]y=7[/tex]

Therefore, the solution to the system of equations is:

(x, y) = (4, 7)

Hence, the point (4,7) is a solution to the system of equations.

Answer:

y = -34

Step-by-step explanation:

Step 1

1/4 y + 9 = 1/2

1/4 + 9 - 9 = 1/2 - 9

1/4 y = -17/2

Step 2

4 * (1/4 y) = 4* (-17/2)

y = -34

Answer:

Jenny gets €18.

Step-by-step explanation:

Jenny gets 3 of every Laura's 2. First you add together both numbers in the ratio. 3+2=5. Then you divide the constant, 30, by the sum, 5. 30/5=6. Then you multiply each number of the ratio by the quotient. 3 x 6=18.

Answer:

"?" = 3

Step-by-step explanation:

The answer can be gotten by subtracting 4 from 7. The 4 is the exponent in (4a^4b), and the 7 is the exponent in 16a^7b. So:

7 - 4 = 3

Therefore, the "?" = 3

Hope this helps :)

Answer:

?=3

Step-by-step explanation:

Okay so with exponents, when multiplying exponents with the same base, you add them.

In your case, we have a^? * a^4=a^7 (this is the only part you need to solve)

so ?+4=7

?=7-4=3

The value of x is -1 and value of y is -1.

Two or more expressions with an Equal sign is called as Equation.

The given equations are

x+5y=-6...(1)

5x – 3y = -2...(2)

Multiply equation 1 with 5

5x+25y=-30..(3)

Subtract equation 2 and equation 3

5x-3y-5x-25y=-2+30

-28y=28

Divide both sides by 28

y=-1

Now plug in y value in equation 1

x=5-6

x=-1

Hence, the value of x is -1 and value of y is -1.

Answer: The smallest value of n is:

n = 21

Step-by-step explanation:

We know that the LCM (least common multiple) between 120 and n is 2520.

We want to find the smallest value of n.

The smallest value of n will be such that n does not share any prime number with 120, then the greatest common factor between 120 and n is 1.

Remember that the LCM between A and B is:

LCM(A, B) = A*B/(GCM(A, B))

Then if the greatest common factor between A and B is 1, we will have:

LCM(A, B) = A*B

Then if the greatest common factor between 120 and n is 1, we have that:

LCM(120, n) = 120*n = 2520

then:

n = 2520/120 = 21

The smallest value of n is n = 21.

Answer

7, x

Step-by-step explanation:

n x + 2 = 7, x

Answer:

Step-by-step explanation:

Step One

Find the supplement of both exterior angles. They both have angles that add with them to make 180 degrees.

x + 105 = 180            Subtract 105 from both sides

x = 180 - 105

x = 75

y + 148 = 180            Subtract 148 from both sides

y = 180 - 148  

y = 32

Step Two

There are two ways to conclude the problem. You could find the value of the 3rd angle of the triangle, or you could notice that x is going to be the sum of the 2 angles you just found. These two angles are called the remote interior angle.

Method One

x = 32 + 75

x = 107

Method Two

32 + 75 + y = 180

107 + y = 180

y = 180 - 107

y = 73

The sum of x + 73 = 180

x = 180 - 73

x = 107

Answer:2.a
