Brainliest to whoever gets this correct The graph of g(x), shown below, resembles the graph of f(x) = x4 - x2, but it has been c

shusha [124]

<h3>Answer: C. g(x) = x^4 - x^2 + 0.5</h3>

Why is this?

We start with x^4 - x^2, which is the original f(x) function. Adding some number to this result will increase the y coordinate of any point on the f(x) function. This is because y = f(x). The only thing that matches is choice C, where we shift the graph up 0.5 units. We say that g(x) = f(x) + 0.5

Choice D goes in the opposite direction, and shifts the graph down 0.5 units.

Choices A and B shift the graph horizontally to the right 0.5 units and to the left 0.5 units respectively.

Answer:

Find the value of x in each of the given figures.

Step by step explanation :

a. .. Let the triangle be ABC

we have to find the value of A

so

ATTQ ( According to the question) we have ::

B = 25°

C = 105° + ___ = 180° ( adjacent angles)

C = 75 ° = 180° - 105° ( transfer 105° from LHS to RHS)

The sum of all interior angles of a triangle is 180° .

so, A+B+C = 180°

A+ 25° + 75° = 180°

A+ 100° = 180°

A= 180° - 100°

A = 80°

therefore answer is 80°

b. .. Let the triangle be ABC.

we have to find the value of x

ATTQ , we have

A= 3x+2°

B=2x°

C = 152° + ___ = 180°

C= 180°- 152° = 28°

The sum of all interior angles of triangle is 180°

so, A+B+C = 180°

3x+2° + 2x° + 28° = 180°

first add the variables then numbers

5x° + 30° = 180°

5x° = 180° - 30°

5x ° = 150°

x° = 150° / 5

x = 30°

therefore answer is 30°

thank you so much..

Solve the simultaneous equations 2x-y=7 3x+y=3

Debora [2.8K]

Answer:

<h2>( 2 , - 3 )</h2>

Step-by-step explanation:

Using elimination method:

2x - y = 7

3x + y = 3

--------------

5x = 10

Divide both sides of the equation by 5

$\frac{5x}{5} = \frac{10}{5}$

Calculate

$x = 2$

Now, substitute the given value of X in the equation

3x + y = 3

$3 \times 2 + y = 3$

Multiply the numbers

$6 + y = 3$

Move constant to R.H.S and change it's sign

$y = 3 - 6$

Calculate

$y = - 3$

The possible solution of this system is the ordered pair ( x , y )

<h3>( x , y ) = ( 2 , -3 )</h3>

---------------------------------------------------------------------

Check if the given ordered pair is the solution of the system of equation

$2 \times 2 - ( - 3) = 7$

$3 \times 2 - 3 = 3$

Simplify the equalities

$7 = 7$

$3 = 3$

Since all of the equalities are true, the ordered pair is the solution of the system

<h3> ( x , y ) = ( 2 , - 3 )</h3>

Hope this helps..

Best regards!!
