Which point of intersection is the solution to the system of equations

Softa [21]

Answer:

Step-by-step explanation:

(Looking at the lines in the graph, the second equation is missing a minus sign, and should be $y=-\frac{1}{3}x + \frac{2}{3}$ )

To find the intersection point of the pair of linear equations, we just need to equate both values of y.

The equations are:

$y=\frac{2}{5}x - \frac{1}{2}$

$y=-\frac{1}{3}x + \frac{2}{3}$

Making the y from one equation equal the y of the other equation, we have:

$\frac{2}{5}x - \frac{1}{2} = -\frac{1}{3}x + \frac{2}{3}$

$\frac{2}{5}x +\frac{1}{3}x = \frac{2}{3} + \frac{1}{2}$

$\frac{6}{15}x +\frac{5}{15}x = \frac{4}{6} + \frac{3}{6}$

$\frac{11}{15}x = \frac{7}{6}$

$x = \frac{7}{6} * \frac{15}{11} =\frac{35}{22} = 1.591$

Then the y-coordinate of the point is found using this x-value in any of the two equations:

$y=\frac{2}{5}\frac{35}{22} - \frac{1}{2}$

$y=\frac{7}{11} - \frac{1}{2}$

$y=\frac{14}{22} - \frac{11}{22}$

$y=\frac{3}{22} = 0.136$

So the coordinate of the crossing point is (1.591, 0.136)

The point that is in this coordinate in the graph is point B.

What is the solution set? −9.5x−1.5>−30<br> x= ?

Alborosie

Hi there!

x > 0.073171.
Why?

First to solve we need to add 30x to both sides of the inequality.

-9.5x - 1.5 + 30x > -30x + 30x
20.5x - 1.5 > 0

Next we need to add 1.5 to both sides.

20.5x - 1.5 + 1.5 > 0 + 1.5
20.5x > 1.5

Finally, divide both sides by 20.5.

20.5x/20.5 > 1.5/20.5

x > 0.073171

So our answer is x > 0.073171.

Hope this helps!

Adam graphs a quadratic function. The vertex of his parabola is (5,0). What is his axis of symmetry

Sloan [31]

Answer:

x=5

this is because the axis of symmetry is where the parabola is symmetric, so it would be 5 because that's the x value of the vertex
