Solve each system of liner equations y=2x+1 x+2y=17 pls help!

GalinKa [24]

Plug y=2x+1 into x+2y=17, we have:
x+ 2(2x+1)= 17
⇒ x+ 2*2x+ 2*1= 17 (distributive property)
⇒ x+ 4x+ 2= 17
⇒ 5x= 17-2
⇒ 5x= 15
⇒ x= 15/5
⇒ x= 3

y= 2x+1= 2*3+1= 7

Final answer: x= 3, y= 7~

The graph of a linear function intersects with the x axis at a point with an abscissa of 4 and with the y axis at a point with a

Leni [432]

We know that

points are
x intercept
A (4,0)

y intercept
B (0,11)

step 1
find the equation of a line
m=(y2-y1)/(x2-x1)--------> m=(11-0)/(0-4)------> m=-11/4

with m and the point B (0,11)
y-y1=m*(x-x1)
y-11=(-11/4)*(x-0)---------> y=-(11/4)x+11

the answer is
the formula of the function is
y=-(11/4)x+11

see the attached figure
