Which graph is the solution to this system y-4x=-1y+x=4
natali 33 [55]

First, let's find the x and y intercepts

In the first equation

y - 4x = -1

Put x =0

y= - 1

(0, -1)

Put y=0 and the n solve for x

0 - 4x = -1

-4x = -1

x=0.25

(0.25 , 0)

The points for the first equation is (0, -1 ) and (0.25, 0)

Next is to find the intercts for the second equation

y + x = 4

put x=0

y = 4

(0, 4)

Put y =0

0 + x = 4

x = 4

( 4, 0)

The points for the second equation are;

(0, 4) and (4, 0)

Below is the graph

PLZZZZZZ DONT SCROLLL HELP A SOUL OUT
nydimaria [60]

Answer:

15 units

Step-by-step explanation:

K(8, 6) and J(-4, -3)

Distance between 2 points

=  \sqrt{(x1 - x2)^{2}  +  {(y1 - y2)}^{2} }

Thus using the formula above,

distance between points J and K

=  \sqrt{ {[8- (-4)]}^{2}  +  {[6- (-3)]}^{2} }  \\  =  \sqrt{ {12}^{2}  +  {9}^{2} }  \\  =  \sqrt{225}  \\  = 15 \: units

A number decreased by 4 equals -12. What is the number? _____
elena55 [62]

x - 4 = -12

I think x = -8 as if you decrease -8 by 4 it will leave us with the answer of -12

x = -8

Hope this helped,
