Answer:
0.5x - y = 1.5
Step-by-step explanation:
First, put the equation in point slope form:
y - y1 = m(x - x1)
y + 2 = 1/2(x + 1)
Distribute the 1/2:
y + 2 = 1/2x + 1/2
Change the fractions to decimals:
y + 2 = 0.5x + 0.5
Subtract y from both sides:
2 = 0.5x - y + 0.5
Subtract 0.5 from both sides:
1.5 = 0.5x - y
Rearrange the equation:
0.5x - y = 1.5
So, the equation of the line in standard form is 0.5x - y = 1.5

42 ÷ w = 7 for w = 6. First, Shaylee must substitute ( ) for ( ). To simplify, Shaylee must divide ( ) by ( ) .
Marcario should use 4 pounds of macadamia nuts and 8 pounds of almonds.
Explanation
given
cost of macadamia nuts per pound=$9
cost of almond nuts per pound=$5.25
cost of the mixture per pound=$6.5
total pounds of the mixture to be made=12
let the pounds of macadamia nuts=x
pounds of almond nuts=y
total pounds of nuts=x+y=12
![x+y=12(1)\\9x+5.25y=6.5(x+y)\\\\9x+5.25y=6.5*12\\9x+5.25y=78(2)](https://tex.z-dn.net/?f=x%2By%3D12%281%29%5C%5C9x%2B5.25y%3D6.5%28x%2By%29%5C%5C%5C%5C9x%2B5.25y%3D6.5%2A12%5C%5C9x%2B5.25y%3D78%282%29)
solving (1) and (2)
x=4
y=8
