Answer 1
The answer is (-2,1) or x is -2 and y is 1. You just need to know how coordinate plane works

Answer:

C

Step-by-step explanation:

A linear equation cannot have a variable as a denominator. So that makes C a non - linear equation. Also, if you graph C, it is NOT a straight line.

What is the slope of this line?
2/3 1/3 -1/3 -2/3

Answers

Answer:

2/3

Step-by-step explanation:

Two points on this line are (0, -3) and (6, 1).

Going from the first to the second, we see a change in x of 6 units and a change in y of 4 units.  The slope of the line is thus m  = rise / run  =  4/6 = 2/3

A right triangle is formed in the first quadrant by the x- and y- axes and a Straight line through the point (2,3). The other vertices are (0,0) (0,Y) (X,0).

a) Write the length L of the hypotenuse as a function of x
b) Find the vertices of the triangle such that its are is a minimum

Answers

Answer:the triangle has (2,) and (0, 4) as its vertices for a maximum area

Step-by-step explanation:let P(x,0) be the x-intercept and Q(0,y) be the y-intercept

label (1,2) as A(1,2)

the slope AP = slope AQ

-2/(x-1) = (2-y)/1

2x - xy - 2 + y = -2

y(1-x) = -2x

y = -2x/(1-x) or 2x/(x-1)

H^2 = x^2 + y^2

= x^2 + ( (2x/(x-1) )^2 --- simplify if needed

(don't know why we are finding the hypotenuse ? )

Area of triangle OPQ

= (1/2)base x height

= (1/2)xy

= (1/2)x(2x/(x-1))

= (1/2) (2x^2/(x-1) )

dA/dx = (1/2) [ (x-1)(4x) - 2x^2(1) ]/(x-1)^2

= (1/2) [ 4x^2 - 4x - 2x^2 ]/(x-1)^2

= 0 for a max of A

2x^2 - 4x = 0

x(2x-4) = 0

x=0 ---- > makes no sense, look at diagram

or

x = 2

then y = 2(2)/(2-1) = 4

the triangle has (2,) and (0, 4) as its vertices for a maximum area

Answers

Answer:

Angles opposite one another that share a vertex are called vertical angles.

When one of these angles undergo a rigid transformation so that it fits exactly over the other, we know that the two angles are congruent

When two parallel lines are crossed by another line called the transversal the angles created inside the parallel lines but on opposite sides of the crossing lines are called alternate interior angles. Angles of this type have the same measurement as one another. Two figures are similar if one can fit exactly over the other after rigid transformations and dilations

Step-by-step explanation:

Vertically opposite angles are always equal (congruent)

The transversal line is the line that crosses two or more parallel lines

Alternate interior angles formed by two parallel lines crossed by a common transversal, are congruent

Two plane geometric figures are similar if they their corresponding interior angles are congruent

Write the output when the input is n. For all the years I knew my grandma, she could barely see. Grandma was legally blind, and yet she knew, by feel, the location of every dish in her kitchen and every work of literature on the bookcase in the living room. I remember especially the bird-like way she peered at things. I'd bring her a copy of my latest school picture, and she'd hold the photo an inch or two from her face, tilt her head to one side, and inspect it before saying, "Very pretty." I used to think she was just being polite, that she really couldn't see me in the picture. But then she'd add, "That pin you're wearing was your mother's." How did she see that little blur on my jacket? The things she could see never failed to amaze me. Watching television with Grandma, I never failed to learn something. Usually it was the complicated plot twist of one of her favorite soap operasThe Guiding Light or As the World Turns. We grandkids would curl up on the big couch while Grandma pulled up a footstool and planted herself right next to the TV, elbows on her knees, to watch the screen. At the commercial break, she'd explain who was marrying whom and who was in the hospital and who had recently come back from the dead. She seemed to have no trouble identifying the characters whom she could barely see. Whether or not she could bring them into sharp focus, they were as real to her as her giggling grandkids. For a treat, we'd sometimes pile into our grandparent's black car for a drive around town: my grandfather at the wheel, my long-legged older brother in the front seat, and Grandma sandwiched between me and my little brother in the backbut sitting so far forward she was practically in the front. I'd imagined all she could see was a blur of images rushing past, yet she could always tell when Grandpa had missed a turn or forgotten to turn on his headlights. Returning home, Grandma would wave at the boy who mowed their lawn and point out the new fruit on the plum tree in their yard. In later years, when I visited from college, Grandma would always be waiting when I pulled up in my old orange car (that's admittedly hard to miss, no matter how bad one's vision). She'd greet me with a bear hug. Then she'd surprise me, every time, with what she could see. Holding my face in her hands, she'd turn my head from side to side and announce, "You got your hair cut!" as if I had won the lottery and forgotten to tell her. I began to wonder if we rely on our eyes too muchif maybe, with our perfect sight, we're actually missing the details my grandma and her poor vision never failed to catch.This story makes the reader think about what we can and cannot see. What question does the author ask us to think about at the end? A. Do people with perfect vision miss out on the details of life? B. Was life just a blur of images racing past our eyes? C. Could Grandma see the things she said she could see? D. Do blind people enjoy life more than people who can see?
