Please look at number 13. and use the slope and write the equation for me
natta225 [31]

Answer:

y - y1 = m(x - x1)

(x1, y1) = (1, -1)  (x2, y2) = (3, 5)

m = \frac{5 - (-1)}{3 - 1}

m = \frac{5 + 1}{3-1}

m = \frac{6}{2} = \frac{3}{1} = 3

m = 3

y - 5 = 3(x - 3)

y - 5 = 3x - 9

y = 3x - 9 + 5

y = 3x - 4

Step-by-step explanation:

In order to use point-slope form to convert to slope-intercept form you have to know one point and the value of the slope. In this case, we know two points, but we don't know the slope. In order to find the slope, you can input the values of the two points into the expression: \frac{y2 - y1}{x2 - x1}

After finding the slope, input the values of one of the points (in this example I used (3,5)) and the slope. After that, multiply the slope by the two terms inside the parentheses. then add 5 to both sides of the equation to isolate y. Now your equation is in slope-intercept form.

I hope this helps :)

liubo4ka [24]

<u>In young children, some brain cells have a </u>plasticity <u>that enables them to take over the functions of damaged or </u><u>missing brain cells.</u>

  • Option E is correct as of the meaning of plasticity the quality of being easily shaped or moulded.
  • So according to meaning option E can be filled in the blank.
  • Option A is incorrect which means weak
  • Option B is incorrect which means a story told about past events remembered by the author.
  • Option C means having a very harmful or effect.
  • Option D is out as meaning unusual or strange in a very annoying or funny way.

Hence E is a suitable answer.

What is plasticity explain?

Plasticity, ability of certain solids to flow or to change shape permanently when subjected to stresses of intermediate magnitude between those producing temporary deformation, or elastic behaviour, and those causing failure of the material, or rupture (see yield point).

A plane flies at x miles per hour in still air. Flying with a tailwind, its speed is 485 miles per hour. Against the wind, its a
Svetradugi [14.3K]

Answer:20mph

Step-by-step explanation:

speed of plane = x mph

Speed of plane with wind = 485 mph

So therefore, speed of wind =

485 - x

Speed of plane against wind = 445 mph

So therefore, speed of wind =

x - 445

So therefore, equating the 2 equations of speed of wind

485 - x = x - 445

Collect like terms

485 + 445 = x + x

930 = 2x

2x = 930

x = 930/2 = 465 mph

Speed of wind = x = 465mph

So we put this value on any of the equations for speed of wind

Speed of wind = x - 445 = 465 - 445

= 20 mph

So therefore, speed of wind = 20mph

Need help with 13 and 14
Svetach [21]

Answer:

13. A

14. C.

Step-by-step explanation:

A relation is a function if there is only one y assigned to each x.

That is if you have a set of points, there should be no repeated x value.

So looking at {(0,0),(-2,4),(-2,-4),(-3,7)} this is not a function because you have two x's that are the same. A.

The slope-intercept form of a linear equation is y=mx+b where m is the slope and b is the y-intercept.

The y-intercept is where the graph goes through the y-axis at.  It goes through at -1 so b=-1.

The slope is rise/run.  So starting from the y-intercept (0,-1) we need to find another point to count the rise & run to... How about (3,1)? That works.  You can do the counting if you want. You could also use the slope formula.

To use the slope formula, I just like to line the points up vertically and subtract vertically then put 2nd difference over the 1st difference.

(0,-1)

-(3,1)

--------

-3  -2

So the slope is -2/-3 or just 2/3.

So the equation is y=2/3 x-1

C.
