What is the solution -3x+y=4 -9x+5y=-1

Mathematics
1 answer:
luda_lava [24]4 years ago
7 0

Answer:

-9x+5y=-1

Slope = -3.600/2.000 = -1.800

 x-intercept = 4/-9 = -0.44444

 y-intercept = 4/-5 = -0.80000

---------------------------------------------------

-3x+y=4

Slope = 6.000/2.000 = 3.000

 x-intercept = 4/-3 = -1.33333

 y-intercept = 4/1 = 4.00000

plz mark me as brainliest :)

If f(x) = 3x3 + 5x2 + x - 1,<br> what would be the<br> P/Q list of possible rational roots?
aivan3 [116]

Answer:

1,-1,3,-3

Step-by-step explanation:

your P is the first number or the number with the highest exponent, your Q is the last number or the number with no variables. So you make a list of what multiplies to your P's and what multiplies to your Q's and you divide your P list by Q. So 3 is made by -1,1,-3,3 and -1 is made by -1,1. So dividing that you get your list of -3,-1,1,3

Exercise 2.1.47 Prove that ifA^-1 exists and AX=0 then X =0.
stepan [7]

Answer:

Step-by-step explanation:

If A^{-1} exist, then we have that A^{-1}\cdot A=1.

Therefore, in the case that AX=0, if we multiply both

terms in the equation by A^{-1}, then we have

A \cdot A^{-1}X=A^{-1}0

and so the equation tells us that

X=A\cdot A^{-1}X=A^{-1}0=0.

PLS HELP<br> I BEG youuuu
Marina CMI [18]

Answer:

19 square units

Step-by-step explanation:

There are a LOT of different ways to solve this problem, most of which involve breaking up the shape into smaller shapes.  For me, it’s easier to draw a rectangle around the figure, find that area, and then subtract the four areas not in the figure.

Rectangle: would be from -3 to 3 (6) and -2 to 4 (6).  6x6=36

The four missing triangles:

AB = 1/2(3)(2)=3

BC = 1/2(2)(4)=4

CD = 1/2(2)(4)=4

DA = 1/2(4)(3)=6

6+4+4+3=17

36-17=19

givi [52]

Answer:

54

Step-by-step explanation:

The numbers are 54, 56 and 58 because 54 + 56 = 110 and 58 + 110 = 168. So lead to 54 being the smallest of the three.
