Answer:
Yes, the table is proportional.
Step-by-step explanation:
The way I check to make sure if a table is proportional, I subtract.
I did this: 122 - 104, 104 - 86, 86 - 68, 68 -50, and 50 - 32.
If all of them equal the same number, then the table is proportional.
If not, then the table is not proportional.
Each equation equals 18.
Therefore, the table is proportional.
Answer:
-1 and 4
Step-by-step explanation:
first you bring the terms on the right side to the left and you get:
-x^2 + 3x + 4 = 0
then you divide both sides of the quadratic by -1:
x^2 - 3x - 4 = 0
then you factor the equation:
(x + 1)(x - 4) = 0
for any product to be zero, one of the factors must be zero. hence, either x + 1 or x - 4 can be zero. so x can be -1 and//or 4.

Answer:
system of equations i think
Step-by-step explanation:
Answer:
Just put in the values in the equation for example 4(1)-5<7 and solve it if the eqution is true at the end than that the right answer
Step-by-step explanation:
In one week he drives 84 miles, so to know how many miles he drove in four weeks, you just gotta multiply it by 4
84 x 4 = 336 miles
