Answer:
plug each half of the ordered pair into the variable term. (x,y)
Step-by-step explanation:
For example (---,20) y=5x 20=5x divide by 5 on both sides 20/5= 4 x=4
Answer: B, D, E
Step-by-step explanation:
Statement 1 cannot be true because f(1)<0.
Statement 2 might be true.
Statement 3 cannot be true because if f is continuous, then for some value between -1 and 0, f(x) is positive by the Intermediate Value Theorem.
Statement 4 might be true.
Statement 5 might be true
You need to determine what is happening in the situation maybe? If the number is increasing then it would be + or x and if they were decreasing it would be / or -
Not sure what this has to do with maths, but probably because it would mean that people would have to buy 2 packs of hot dog buns just to get 8 hot dog buns, which makes him more money?
Answer:
x = 90
Step-by-step explanation:
∠1 = ∠4 ( corresponding angles are congruent ), thus
3x - 160 = x + 20 ( subtract x from both sides )
2x - 160 = 20 ( add 160 to both sides )
2x = 180 ( divide both sides by 2 )
x = 90
