What values of x and y satisfy the system of equations {2x+12y=−173x+2y=7? Enter your answer as an ordered pair, like this: (42, 53) If your answer includes one or more fractions, use the / symbol to separate numerators and denominators. enter your answer like this: (42/53, 64/75) If there is no solution, enter "no"; if there are infinitely many solutions, enter "inf."

4a. is 3 miles every hour

4b. is 1/3 of an hour per mile

step-by-step explanation:

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1

a and c

for infinitely many solutions we require both left and right sides to be equal

distribute and simplify

a

14 - 8x = 20 - 8x - 6 = 14 - 8x ← both sides equal so infinite solutions

b

6x - 54 = 6x - 54 + x = 7x - 54 ← not equal

c

4x + 16 = 4x + 10 + 6 = 4x + 16 ← both sides equal so infinite solutions

d

5x - 40 + 10 = 5x + 10

5x - 30 = 5x + 10 ← not equal
