Answer:
x = 3
y = 1
Step-by-step explanation:
9x - y = 26 ---------------(I)
9x + y = 28 ---------------(II)
9x - y = 26
9x = 26 + y
Substitute 9x = 26 + y in equation (II)
26 + y + y = 28 {add like terms}
26 + 2y = 28 {subtract 26 from both sides}
2y = 28 - 26
2y = 2 {divide both sides by 2}
y = 2/2
y = 1
Substitute y =1 in equation (I)
9x - 1 = 26
9x = 26 + 1
9x = 27
x = 27/9
x = 3
x = 3
y = 1
Answer:
for the first question b,
it doesn't make sense for choice a to have -2 people in the car. You can't have a negative amount of people. For choice choice c, you can't have half a person, and for choice d, Ms. Valdez can only have under 5 people, not five people exactly.
for the second question I need to see the whole inequality, generally there is a variable, and all i see is <-1, which is invalid.
hope this helps, if it does like it pls!!

Answer:
The slope is -3
Step-by-step explanation:
Count from A to B downwards which is 3 but since we're counting down it's a negative 3. Then from that spot count how many spaces you are from B which is 1. So its -3/1 which is -3. Basically rise/run
