What are all the solutions of x2 + 3x - 4 = 0?<br> 3 ооооооо<br> DONE
Allisa [31]

Answer:

x = -4, x = 1

Step-by-step explanation:

Now I do not know why you said done, but just saying, if you are done with a question, you should delete it. Now I am just going to assume you knew this and move on with the solution of the problem.

When you factor this equation, you will get (x+4)(x-1).

You can then solve for x using zero product property. The first root is -4 and the second root is 1.

Y=2 Enter the solution (x, y) to the system of equations shown 7y+3x=5
AnnyKZ [126]

Answer:

(x, y) = (-3, 2)

Step-by-step explanation:

Put the given value of y into the equation and solve for x.

... 7·2 +3x = 5

... 3x = -9 . . . . . . subtract 14

... x = -3 . . . . . . . divide by the x-coefficient

The solution (x, y) is (-3, 2).

Will Mark Brainlest Help Please ,,,, ​
insens350 [35]

\\ \sf\longmapsto 2x+y=2

\\ \sf\longmapsto 2x=2-y

\\ \sf\longmapsto x=\dfrac{2-y}{2}\dots(1)

And

\\ \sf\longmapsto x+1=y+2

\\ \sf\longmapsto x=y+2-1

\\ \sf\longmapsto x=y+1

  • Put the value

\\ \sf\longmapsto \dfrac{2-y}{2}=y+1

\\ \sf\longmapsto 2-y=2(y+1)

\\ \sf\longmapsto 2-y=2y+2

\\ \sf\longmapsto 2-2=2y+y

\\ \sf\longmapsto 3y=0

\\ \sf\longmapsto y=\dfrac{0}{3}

\\ \sf\longmapsto y=\infty

  • Put in eq(1)

\\ \sf\longmapsto x=\dfrac{2-y}{2}

\\ \sf\longmapsto x=\dfrac{2-\infty}{2}

\\ \sf\longmapsto x=\dfrac{2}{2}

\\ \sf\longmapsto x=1

I need help ! It’s says try to analyze it for clues about its purpose and meaning .
Lyrx [107]

Answer:

See explanation

Step-by-step explanation:

The scatter plot shows that there is a negative linear trend.  That as the distance to the coffee shop increases, whatever the y value represents goes down.

6 below and 6 above

(1,4)  (7,1)  Coordinates of the two points on the trend line

I can't see what the Y axis represents so can't really explain the prediction but as the distance to the coffee shop increases, whatever the Y axis represents will decrease.
