(a4-6a+5)-(a4-3a+4a-6)
by expressing like term
a4-a4=0
-6a-(-3a+4a)=-5a
5-(-6)=11
:we have-5a+11

Which linear function has the same y-intercept as the one that is represented by the graph? On a coordinate plane, a line goes t
Zolol [24]

The line which is having same y intercept as the line which passes through points (-4,0) and (0,3) is y=2x+3.

Given Points through which the line passes through are (-4,0) and (0,3)

We have to find the equation whose y intercept is equal to the y intercept of the line whose points given above.

First of all we have to find the y intercept of the line which passes through (-4,0) and (0,3). Equation of line is :

y-y1=(y2-y1)/(x2-x1)*(x-x1)

y-0=(3-0)/(0+4)  *(x+4)

y=3/4(x+4)

y -intercept exists where x=0

put x=0

y=3

So the options are:

  • y=2x-4
  • y=2x-3
  • y=2x+3
  • y=2x+4

By putting the value of x in all options we will find

y=-4

y=-3

y=3

y=4

So the third option is correct.

Hence the line whose y-intercept matched with the given line is y=2x+3.

Help for all, will mark brainliest!!!!! :)
Nat2105 [25]

Answer:

Number 4: Using Pythagoras Theorem,

\sqrt{30^2+40^2} =50

Number 5:

\sqrt{41^2-40^2}=9

3:

\sqrt{11^2+60^2} =61 It is a right triangle

4:

\sqrt{9^2+37^2} =38.09 Not a right triangle

For the last one:

\sqrt{(\sqrt{20^2+6^2})^2+6^2} =2\sqrt{118}

Rounded down (because the answer needs to be a whole number) is 21
