Answer:
The answer is 4 and -5.
Step-by-step explanation:
Working under the assumption that the first term is not 2x, but 2x², you can find the zero values by factoring the expression:
With it factored we can see that x being equal to -5 or 4 will give a zero value
Let's also see it plotted, as the question said to use a graphing calculator:
Answer:
Step-by-step explanation:
The shop sold 70 ice cream cones. It means that x + y = 70Small cones cost 3.95 and large cones cost 5.75. The total sales made from the selling 70 ice creams is $370.10. It means that 3.95x + 5.75y = 370.1 - - - - - - - - - -1Substituting x = 70 - y into equation 1, it becomes3.95(70 - y) + 5.75y = 370.1276.5 - 3.95y + 5.75y = 370.1- 3.95y + 5.75y = 370.1 - 276.51.8y = 93.6y = 93.6/1.8y = 52x = 70 - 52x = 18

Answer:
19
Step-by-step explanation:
The pattern is that it +6 every number.
-5 + 6 = 1
