I'm failing math. I need help Amanda purchased seven tomato plants at a total cost of $26. The cost of the small tomato plants was $2 each. The cost of the large tomato plants was $5 each. The graph below represents this situation.

what is the slope line of x+y=7
A:7
B:-2/5
C:26/5
D:-1

Compare the subtraction problems 6/8 - 5/8 = 1/8 and 6/9 - 7/9 = 1/9 why is the answer to the first problem positive and the answer to the second problem negative

The average human heart beats 1.15 \cdot 10^51.15⋅10 5 1, point, 15, dot, 10, start superscript, 5, end superscript times per day. there are 3.65 \cdot 10^23.65⋅10 2 3, point, 65, dot, 10, start superscript, 2, end superscript days in one year.how many times does the heart beat in one year? write your answer in scientific notation, and round to one decimal place.

Give me the equations of two lines that have the same slope but are not parallel.
