How many solutions does the system  y  = −7x  + 3 and  y  + 7x  = 10 have?

No solutions.

Step-by-step explanation:

y = −7x + 3

y + 7x = 10

Rearranging the first equation we get:

y + 7x = 3

Note that in the last 2 equations we have  y + 7x on the left side and a 3 and 10 on the right; y + 7x cannot  be equal to 3 and 10, therefore there are no solutions.

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
