When you multiply the two binomials you get a quadratic function with a negative lead coefficient.
This function will fall on the left and fall on the right.
If the lead coefficient were positive the function would rise in both the left and the right.
Answer:
-5
Step-by-step explanation:
15-5=10
10-5=5
5-5=0
0-5= -5
Answer: b= 45
Step-by-step explanation:
Step 1: Subtract 5b from both sides.
2b+23−5b=5b−112−5b
−3b+23=−112
Step 2: Subtract 23 from both sides.
−3b+23−23=−112−23
−3b=−135
Step 3: Divide both sides by -3.
−3b
/-3 = -135/-3
Answer:
$6.94
Step-by-step explanation:
Let's say that the cost of the hamburger without tax in 100%. Then the price with tax is 108% because there is an 8% tax. Therefore, $7.50 corresponds to 108%. if we divide 7.50 by 108 we get 0.0694444 or 1%. Finally, we multiply by 100 to get 100% or the cost without tax which is $6.94.
