Which ordered pairs in the form (x, y) are solutions to the equation (x + 7)y = 10? Choose all answers that are correct. A.(−9, −5) B.(−8, 10) C.(−2, 2) D.(3, 5)
1 answer:
What you do is to substitute the first number for x and the second for y: (x+7)y=10 a): (-9+7)*-5=10 (-2)*-5=10 10=10 yes, it's a solution! b) (-8+7)10=10 -1*10=10 -10=10 no, not a solution! c) (-2+7)2=10 5*2=10 yes, a solution!! d) (3+7)*5=10 50=10 no, not a solution!

I'm assuming you didn't mean to repeat each number 3 times. If she did 184 jumping jacks in 4 minutes that means she did 46 jumping jacks per minute.
A1=24 <span>n=500(seq #) </span> <span>d=how much u add each time=6 </span> <span>a(n)=24+(500-1)(6)=3018</span>
It would be J. This is because the opposite of -3.5 would be 3.5 and the absolute value is just a positive integer or positive number so that would be 3.5 as well so its J
