Can anyone answer
i dont understand this.

y < -2x +4

Step-by-step explanation:

First of all, you need to determine the equation of the dashed line. It goes down 2 units for each 1 unit to the right, so has a slope of -2/1 = -2.

The y-intercept is clearly shown by the point (0, 4) as being 4.

The slope-intercept form of the equation of a line is ...

... y = mx +b . . . . . where m is the slope (-2) and b is the y-intercept (4)

Your line's equation is ...

... y = -2x +4

You're not done, yet.

Because the graph is shaded on one side of this line, the graph is of an inequality, not a line. (The line is just the boundary of the solution region.) This graph is shaded below the line, so y-values that are less than those on the line are part of the solution.

Because the line is dashed, the inequality symbol used is one that indicates the line itself is not part of the solution.

So, the desired inequality is ...

... y < -2x +4 . . . . . . . . . . "less than" because shading is below; not "≤" because the line is dashed.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
