Can someone pls help w finding the x and y intercepts of this? <br><br> y=x^2-2x
AysviL [449]

Answer:

<u>y-intercept</u><u> </u><u>is</u><u> </u><u>0</u><u>,</u><u> </u><u>x-intercept</u><u> </u><u>is</u><u> </u><u>0</u><u> </u><u>and</u><u> </u><u>1</u>

Step-by-step explanation:

For y-intercept, x=0 :

{ \tt{y =  {(0)}^{2} - 2(0) }} \\ { \tt{y = 0}}

For x-intercept, y=0 :

{ \tt{0 =  {2x}^{2} - 2x }} \\ { \tt{2x(x - 1) = 0}} \\ { \tt{x = 0 \:  \: and \:  \: 1}}

Tommy used a straightedge and a compass to construct a square inside circle C, as shown.
myrzilka [38]

Answer:

The correct options are;

A. Construct a perpendicular bisector of the diameter AB

D. Use the compass to draw a circle centered at point C

E. Use the compass to draw two arcs of the same radius centered at point C

F. Use the straightedge to draw diameter AB of the circle

G. Use the straightedge to draw lines connecting the endpoints of the two diameters

Step-by-step explanation:

To draw an inscribed square of a circle, the circle is first constructed. The diameter of the circle is drawn with a straight edge to find the first two vertices of the intended inscribed square. The perpendicular bisector of the diameter is then drawn intersecting the circumference to provide the other two vertices of the square.

The straightedge is then used to draw lines that connect the endpoints of the two diameters to form the inscribed square of the circle.

Ms. Chibbaro asked her students to find an expression equivalent to 7 - 3(4 - 2x) - 10x Jon had the work shown to the Left on hi
rjkz [21]

Answer:

-15 + 6x

Step-by-step explanation:

Given

Expression: 7 - 3(4 - 2x) - 10x

Required

Determine Jon's error and make corrections.

Also, give the equivalent of the expression

The question has missing details because Jon's workings is not listed.

One mistake student's make during multiplications that involves minus (-) and plus (+) is in the signs.

So, watch out for the signs to know where the error is.

However, I'll give an equivalent of the given expression

7 - 3(4 - 2x) - 10x

Open Bracket

7 - 12 + 6x - 10

Collect Like Terms

7 - 12 - 10 + 6x

-15 + 6x

<em>Hence, the given expression is equivalent to </em>-15 + 6x<em></em>
