I am having trouble with linear graph equations 2y+x=-5
allochka39001 [22]
Make it into slope intercept form which is y=mx+b
subtract x ffrom both sides
2y=-5-x
divide by 2
y=-1/2x-5/2

y=mx+b
m=slope
b=y intercept or where the line passes through the y-axis


now one way is to graph points by subsituting
if x is 0 then y=-5//2
if x=1 then y=-3
if x=-5 then y=0

another way is to find out where the line passes though the y and x axis or the y and x intecepts respectively

the y intercept is when x=0
the x intecept is when y=0

so set each to zero and solve
if x=0
y=-1/2(0)-5/2
y=-5/2
the line passes throught the y axis at -5/2, plot the point (0,-5/2) on the y axis



then set y to zero
0=-1/2x-5/2
add 5/2 to both sides
5/2=-1/2x
multiply -1
-5/2=1/2x
multiply by 2
-5=x
therefor the line passes through tthe x axis at (-5,0)
then draw the line between the 2 points

here is the graph

Help me figure out a
nika2105 [10]

Answer:

  • a ≈ 615.272
  • b ≈ 1.61875

Step-by-step explanation:

My graphing calculator can solve this problem two ways. It can do a least-squares fit of the exponential data, or it can do a least-squares fit of the logarithm of the data. The answers come out different.

In "log mode", the parameters of the exponential equation are computed as ...

  a ≈ 615.272

  b ≈ 1.61875

__

With log mode turned off, the "a" parameter is lower (≈553.071), and the "b" parameter is higher (≈1.65573). This mode gives a better fit to the larger data values, at the expense of a poorer fit to the lower data values, as you might expect.

Cara's bathroom floor has an area of 2 2/3 square yards.She lays down a rug that has an area of 1 1/4 square yards.Do I have to
lianna [129]
It should be Additional because she adds on another rug right so you just add 2 /23 + 1 1/4 and you will get your answer hope this helps
! and if u subtract that means your removing 1 rug and that's not in the question. :D
