Answer:

See explanation

Step-by-step explanation:

To solve the equation 4x^2 =x^2+7 graphically, we need to consider left and right parts of this equation separately.

Left side gives us the function y=4x^2. The graph of this function is shown with green curve in attached diagram.

Right side gives us the function y=x^2+7. The graph of this function is shown with blue curve in attached diagram.

The x-coordinates of the points of their intersections are the solutions to the equation 4x^2 =x^2+7

From the graph you can see that the solutions are

x_1\approx -1.528\\ \\x_2\approx 1.528

Bonjour, je dois faire un exercice de maths pour lundi:
Elza [17]

Answer:

A: 8x^2 + 2x - 1

B: 5x - 2x^2 + 18

C: 34x - 6x^2 - 40

D: 70 - 28x

Step-by-step explanation:

A: (2x+1)(4x-1) = 8x^2 - 2x + 4x - 1 = 8x^2 +2x - 1

B: (2x - 9)(-x -2) = -2x^2 -4x + 9x + 18 = 5x - 2x^2 + 18

C: (3x - 5)(8 - 2x) = 24x - 6x^2 - 40 + 10x = 34x-6x^2-40

D: (10-4x) x 7 = 70-28x

Which set represents the same relation as the graph below?
Paha777 [63]

The set that represents the same relation as the graph given is: B. (-5, 4), (-3, -2), (-1, -2), (2, 0), (3, 3), (4, 5), (6, -4).

<h3>What is a Relation?</h3>

A relation is defined as a relationship between the input and output, which can be displayed on a graph on a coordinate plane.

From the graph as shown in the image attached below,

The set that has same coordinate points as indicated on the graph is:

B. (-5, 4), (-3, -2), (-1, -2), (2, 0), (3, 3), (4, 5), (6, -4).

Solve for x: 3(9-8x-4x)+8(3x+4)=11
inysia [295]

Answer:

x=4

Step-by-step explanation:

3(9-8x-4x)+8(3x+4)=11

Subtract  4 x  from  − 8 x

3 ( 9 − 12 x ) + 8 ( 3 x + 4 ) = 11

Distribute

27 − 36 x + 24 x + 32 = 11

Simplify

− 12 x + 59 = 11

Subtract 59 to both sides

− 12 x = − 48

Divide by -12

x=4
