XE(-œ,-5)
Answer:
38=7x-y
Step-by-step explanation:
standard form= Ax+By+C
(y-3=7(x-5))
(y-3=7x-35)+3 to both sides
(y=7x-38) +38 to both sides
(y+38=7x) -y to both sides
38=7x-y
you have to move the 38 and y because if you moved the x value, than A becomes negative and it can't be in standard form
Answer:
50.264 grams -> 50.2
Step-by-step explanation:
If seeds are 8 per pound then you need to find the unit rate and make a proportion with how much she spent. So you can make a ratio of 1(pound) / $8 compared to x(pounds) / $10. Then, cross-multiply.
10 = 8x. Divide both sides by 8
10/ 8 = x Simplify the fraction
1 1/4 = x
So, she bought 1 1/4 pounds of seeds
