Find the greatest solution to the following system of equations. Write as x= ?

y=x^2+x-2 and y=-x+1

Answers

Answer:

we have x=1, y=0 and x=-3, y=4

Step-by-step explanation:

We need to solve the equations: [tex]y=x^2+x-2 \ and \ y=-x+1[/tex]

Let:

[tex]y=x^2+x-2--eq(1)\\ y=-x+1---eq(2)[/tex]

Putting value of eq(2) into eq(1)

[tex]-x+1=x^2+x-2\\Solving:\\x^2+x-2+x-1=0\\x^2+2x-3=0\\Factorising:\\x^2+3x-x-3=0\\x(x+3)-1(x+3)=0\\(x-1)(x+3)=0\\x-1=0 \ or \ x+3=0\\x=1 \ or \ x=-3[/tex]

Now finding values of y for x=1 and x=-3

[tex]For \ x=1, \\y=-x+1 \\y=-1+1 \\y=0\\For \ x=-3\\ y=-x+1\\y=-(-3)+1 \\y=3+1\\y=4[/tex]

So, we have x=1, y=0 and x=-3, y=4

I'm not sure what this means, please help me I'll give you 10 points ;)

Answers

Answer:

So all the possible solutions are:

[tex]\bold{523,~400,~379~and,~378.6}[/tex]

Solution Steps:

First you need to solve the real inequality to understand how to find the rest of the possible equations.

Add 78 to both sides:

[tex]78+78=[/tex] Cancels Out[tex]300+78=378[/tex]

So now we know the real answer, but it ask for all possible answers.

(Means anything larger than 300 when you plug it into x - 78 > 300.)

Numbers that are greater than 378:

1.) [tex]377-78=299 > 300[/tex] (False)

2.) [tex]523-78=445>300[/tex] (True)

3.) [tex]0-78=-78>300[/tex] (False)

4.) [tex]-62-78=-140>300[/tex] (False)

5.) [tex]400-78=322>300[/tex] (True)

6.) [tex]379-78=301>300[/tex] (True)

7.) [tex]222-78=144>300[/tex] (False)

8.) [tex]378.6-78=300.6>300[/tex] (True)

Find the value of the variable that makes the equation true 3x-11=-2x+19

Answers

Answer:

x = 6

Step-by-step explanation:

Given

3x - 11 = - 2x + 19 ( add 2x to both sides )

5x - 11 = 19 ( add 11 to both sides )

5x = 30 ( divide both sides by 5 )

x = 6

During geometry class, students are told that ΔTSR ≅ ΔUSV. Marcus states that ΔTSR is mapped to ΔUSV by performing a rotation about point S. Sam states that ΔTSR is mapped to ΔUSV by a reflection across the line that goes through point S. Determine if either student is correct.

Answers

Answer: Marcus is correct.

i got it right on Edge2020

Step-by-step explanation:

Transformation involves changing the position of a shape through translation, dilation, rotation and reflection.

Marcus's claim is correct.

The triangles are given as: ΔTSR and ΔUSV

By comparison, we can see that point S is on both triangles, and this point on both triangles corresponds.

So, to map ΔTSR to ΔUSV, then ΔTSR must be rotated about point S to ΔUSV or rotate ΔUSV about point S to ΔTSR.

Hence, Marcus is correct, and Sam is not.

What does it mean if (2, 20) is a solution of y = 10x and x +y = 22 ?
2, 20) makes exactly one of the equations true.

(2, 20) makes at least one of the equations true.

(2, 20) makes neither equation true.

(2, 20) makes both equations true.

Answers

Answer:

(2, 20) makes both equations true

Step-by-step explanation:

If a point is a solution for 2 equations, that means that it makes both equations true.

So, since (2, 20) is a solution to both y = 10x and x + y = 22, that means it makes both of the equations true.

P and Q are points on the line
4x + 2y = 8

Complete the coordinates of
P and Q

P (0,?)

Q(?,0)

Answers

Answer:

P(0, 4 ), Q(2, 0 )

Step-by-step explanation:

To find P, with an x- coordinate of 0

Substitute x = 0 into the equation and solve for y

4(0) + 2y = 8 , that is

2y = 8 ( divide both sides by 2 )

y = 4

Thus P(0, 4 )

To find Q with a y- coordinate of 0

Substitute y = 0 into the equation and solve for x

4x + 2(0) = 8, that is

4x = 8 ( divide both sides by 4 )

x = 2

Thus Q(2, 0 )

He stretched himself on his back and looked straight up at the blinking stars. But he was not thinking of them nor of anything but a certain spring day when the bees were humming in the clematis; when a girl was saying goodbye to him. He could see her as she unclasped from her neck the locket which she fastened about his own. It was an old fashioned golden locket bearing miniatures of her father and mother with their names and the date of their marriage. It was her most precious earthly possession.Octavie wore a plain black dress, severe in its simplicity. A narrow belt held it at the waist and the sleeves were gathered into close fitting wristbands. She had discarded her hoopskirt and appeared not unlike a nun. Beneath the folds of her bodice nestled the old locket. She never displayed it now. It had returned to her sanctified in her eyes; made precious as material things sometimes are by being forever identified with a significant moment of one's existence.Octavie felt as if she had passed into a stage of existence which was like a dream, more poignant and real than life. There was the old gray house with its sloping eaves. Amid the blur of green, and dimly, she saw familiar faces and heard voices as if they came from far across the fields, and Edmond was holding her. It was as if the spirit of life and the awakening spring had given back the soul to her youth and bade her rejoice. Hurry!!!
