Answer:
12
Step-by-step explanation:
Answer- vertical;congruent
Ok so we’ll put the first equation into slope int form
4y=2x-9
y=1/2x -4/9
since the likes are parallel, the slope of the line we are trying to write an equation for is 1/2
equation:
y-2=1/2(x-7)
Answer:
The intersection point is
Step-by-step explanation:
we have
------> equation A
------> equation B
we know that
The intersection point both graphs represent the solution of the system of equations
Using a graphing tool
The intersection point is
see the attached figure
2 seperate questions
what is the weight of 1 gallon and what is the cost per gallon
weight/1gallon=wieght/gallons=129.8lb/22gal=5.9lb/1gal
weigth is 5.9lb per gallon
cost per gallon=cost/gallons=$91.30/22gal=$4.15/1gal
cost is $4.15 per gallon
if ya wanted to estimate
lb per gallon is 129.8lb/22gal≈130/20=6.5lb/gal=6.5lb per gal
cost is $91.30/22gal ≈90/20=9/2=$4.50 per gal
