On a coordinate plane, a curved line with a minimum value of (negative 2.5, negative 12) and a maximum value of (0, negative 3)
alekssr [168]

The points on the graph of (-4, 0), (-2.5, -12), and (0, -3), gives;

  • F(x) > 0 over the interval (-∞, -4)

<h3>Which method can be used to find the true statement?</h3>

From the description of the graph, we have;

Furthest point left of the graph = (-4, 0)

The furthest point right on the graph = (0, -3) = The maximum point

The minimum point = (-2.5, -12)

F(x) < 0 at the minimum point

The minimum point is to the right of x = -4

The point the graph crosses the y-axis = (0, -3)

Therefore;

The interval of the graph where F(x) is larger than 0 is to the left of (-4, 0), is the interval (-∞, -4)

The true statement is therefore;

  • F(x) > 0 over the interval (-∞, -4)

Substitution to solve the linear system
STALIN [3.7K]

y=4x+2. eq1

y=5x. eq2

4x=2-y

x=(2-y) /4

substitute in equation 2

y=5(2-y) /2

y=(10-5y)/2

4y=10-5y

9y=10

y=10/9

substitute in equation 2 or 1

substituting in equation 2

10/9=5x

x=10/45

x=10/45 y=10/9

you can verify it also.
