Answer:

Create a circle with the origin as its center and a radius of the origin and point A, then locate a point on the circle that is 90° clockwise from point A.

Step-by-step explanation:

90° clockwise rotation of point A (1, 4) around the origin

Answer options

Create a line perpendicular to the y-axis from point A, and locate a point on the perpendicular line that is equidistant to the distance between the y-axis and A.

Incorrect. It describes the reflection over y axis

Create a circle with the origin as its center and a radius of the origin and point A, then locate a point on the circle that is 90° clockwise from point A.

Correct

Create a line perpendicular to the x‒axis from point A, and locate a point on the perpendicular line that is equidistant to the distance between the y-axis and A.
Incorrect. It is the transformation by 1 unit down.

Create a circle with point A as its center and a radius of the origin and point A, then locate a point on the circle that is 90° counterclockwise from point A.
Incorrect. It is the transformation of origin but not point A

Solve the equation: 2+3x=4+x(2+x)

grandymaker [24]

2 + 3x = 4 + 2x + x^2
x^2 - x + 2 = 0

(x - 0.5)^2 - 0.25 + 2 = 0

(x - 0.5)^2 = -1.75

x - 0.5 = +/- sqrt 1.75 * i

x = 0.5 + 1.32i , 0.5 - 1.32i answer

Solve the system by substitution. 4x+3y=5x=4y+6Options: A. The solution is ____B. There are infinitely many solutions. C. There

zvonat [6]

So we have the following system of equations:

$\begin{gathered} 4x+3y=5 \\ x=4y+6 \end{gathered}$

We need to solve it by substitution. This means that we have to take the expression for x given by the second equation and replace x with it in the first equation:

$\begin{gathered} 4x+3y=5 \\ 4\cdot(4y+6)+3y=5 \\ 16y+24+3y=5 \\ 16y+3y=5-24 \\ 19y=-19 \\ y=-\frac{19}{19}=-1 \end{gathered}$

So y=-1. If we use this value in the second equation:

$\begin{gathered} x=4y+6 \\ x=4\cdot(-1)+6 \\ x=-4+6 \\ x=2 \end{gathered}$

So we have x=2 and y=-1 which means that there's one solution. Then the correct answer is A and the solution is (2,-1).
