Answer:
Step-by-step explanation:
(2, -1) & (-1, -2)
(-2+1)/(-1-2)= -1/-3= 1/3 is the slope of the line
5(5r-7)=-185
25r - 35 = - 185
25r = - 150
r = - 6
You can plug in the numbers to check.
Y - 2x > 17
(8) -2(-5) > 17
8 + 10 > 17
18 > 17
This is true so
Final answer:
Yes, (-5,8) is a solution
Answer:
192 pounds of $2.5 brand
288 pounds of $2.8 brand
Step-by-step explanation:
From the information we can write an expression that relates the two brands the total pounds of coffee the grocer wants to see. Let x be pounds of the coffee brand 1 and y be pounds of the coffee brand 2.Equation 1:
We know that the price of will be equation 2:
Two equations and two unknowns we can solve for x and y:
Substitute into the second equation:
Therefore he uses 288 pounds of brand two at $2.80 and 480-288=192 pounds of brand 1 at $2.50
Answer:
No
Step-by-step explanation:
Given that:
Amount earned when a student does comminty service = $5
Number of students in club = 12
Amount earned E, is a function of number of members (n) who does community service.
Hence,
E = n * amount earned per member
Is 24 a possible output?
To test, then E = 24
24 = n * 5
24 = 5n
24/5 = 5n/5
4.8 = 5
Hence, 24 is not a possible output, be use number of membwra cannot be a decimal
