Answer:
Step-by-step explanation:
5(t+3)=-3.5
distribute
5t+15=-3.5
subtract 15 from both sides
5t= -18.5
divide both sides by 5
t=-3.7
Answer:
(-6, -5)
Step-by-step explanation:
If you go left 9 times from 2, it goes to -6. Ex: 2, 1, 0, -1, -2, -3, -4, -5, -6. The same goes for 3 units up from -8.
8x + 7y = 39
4x - 14y = -68
(multiply each term in second equation by -2)
8x + 7y = 39
-8x + 28y = 136
(add both equations)
35y = 175
(divide both sides by 35)
y = 5
(substitute value of y in one of the equations)
8x + 7(5) = 39
8x + 35 = 39
8x = 4
x = 1/2
(x, y) = (1/2, 5)
Answer: y = x + 10
Explanation: substitute x by the numbers in the first column and add that by 10 which would be equal to the numbers in the second column (y) for example 1+10= 11
Answer:
A number times five is greater than fifteen. A number less negative seven is less than or equal to five. The difference between a number and seven is less than zero. The sum of a number and seven is greater than or equal to fifteen.
