Answer:
Step-by-step explanation:
a.
2y - 3x = 5
2(-2) - 3x = 5
-4 - 3x = 5
-3x = 9
x = -3
(-3,-2) is another solution
b.
(-1,1)
2y - 3x = 5
2(1) - 3(-1) = 5
2 + 3 = 5
5 = 5
true, the point is a solution to the equation because the equation is true after substituting x and y with the point (-1,1)
(4,1)
2y - 3x = 5
2(1) - 3(4) = 5
2 - 12 = 5
-10 = 5
not true, the point is not a solution to the equation because the equation is not true after substituting x and y with the point (4,1)
c. You can use the points from the given (-1,1) and (-3,-2) to form a line. You then shade whichever half solves the solution using points on the graph.
Answer is 7950,72. You can solve it's task on calculator.
Answer:
Pretty sure its A and B
Step-by-step explanation:
Slope is -6/5, so that leaves just A B and E
Plugged it in, only A and B were correct
Answer:
The probability is 
Step-by-step explanation:
From the question we are told that
The sample size is n = 175
The population proportion is p = 0.45
Generally the mean of the sampling distribution is 
Generally the standard deviation is mathematically represented as
=> 
=> 
Generally the probability of that the sample proportion of orange candies will be between 0.35 and 0.55 is
=> 
Generally 
So
=> 
From the z-table
and
So
=>
Answer: 126
Step-by-step explanation: this is the distributive property so you multiply the number outside the parentheses times the numbers inside the parentheses
