2x + 8y = 20
y = 3

Can someone tell me the answer to this pls I beg you

x=-2

Step-by-step explanation:

y=3 so 8y=24 s 2x+24=20 if you subtract 24 from both sides you get 2x=-4 divide by 2 on both side and you get x=-2

2x+8y=20

Substitute Y

2x+8(3)=20

Multiply 8 * 3

2x+ 24= 20

substract 24 from 20 do it to the other side as well were basically doing inverse operation in order to keep the varieble by itself

2x=-4

Then do inverse operation of multiplication which is division

2x= -4

2     2

2x will cross out and x will be left, -4/ 2 equals -2

so x= -2

The answer will be (-2, 3) or if you're just solving for x its going to be -2

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

the graph in the attached figure

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)
