(x+2x+5)-10=22
3x+5=32
3x=27
x=9
So, the numbers are 3 and 11

X = 2y + 5
(x + 2y + 5) - 10 = 22
(2y + 5 + 2y + 5) = 4y + 10
(4y + 10) - 10 = 22
4y = 22 y = 5.5
x = 2(5.5) + 5 x = 16
x = 16 y = 5.5

Describe the solution of g(x) shown in the graph.

Ugo [173]

Answer:

All real solutions

Step-by-step explanation:

The given graph is a maximum quadratic function.
The solution to the graph is where the graph intersects the x-axis.
We can see from the graph that, the function intersected the x-axis at two different points, hence its discriminant is greater than zero.
Hence the solution of g(x) are two distinct real solutions.
The solutions are not whole numbers because the x-intercepts are not exact.
The solutions are also not all points that lie on g(x)
The first choice is correct.

Given A(3, 4), B(4, 3) and C(2, 1), what are the coordinates of C', the image of C under a rotation of 90 degrees about the orig

Aleks [24]

<u>Given</u>:

The coordinates of the points A, B and C are (3,4), (4,3) and (2,1)

The points are rotated 90° about the origin.

We need to determine the coordinates of the point C'.

<u>Coordinates of the point C':</u>

The general rule to rotate the point 90° about the origin is given by

$(x, y) \Rightarrow(-y, x)$

Substituting the coordinates of the point C in the above formula, we get;

$(2, 1) \Rightarrow(-1, 2)$

Therefore, the coordinates of the point C' is (-1,2)
