Answer:
-5/7
Step-by-step explanation:
Look at the graph. As we move from left to right from (-3, 2) to (4, -3), x increases by 7 and y decreases by 5. Thus, the slope is
m = rise/run = -5/7.
Y = -2x - 4
y = 2x +4
add the two equation
2y = 0 , y =0
2x + 4 = 0
2x = -4
x = -2
I would actually say that the correct answer would be the first option. 19 would be considered to be a whole numbers because it contains not decimal or a fraction. And also, this would also be a rational number because it would not have a terminating decimal.
Your answer: (Option A.)
Answer:
Both expressions are equivalent to 264 when t=9.
Step-by-step explanation:
Two expressions in question are :-
Expression 1 :- 8(4t-3)
Expression 2 : - 32t-24
When t = 9 , in expression 1
8(4*9-3) = 8 (33)= 264
When t = 9, in expression 2
32*9-24 = 288-24=264
So, Both expressions are equivalent to 264 when t=9.
When t = 5 , in expression 1
8(4*5-3) = 8 (17)= 136
When t = 5, in expression 2
32*5-24 = 160-24=136
Both expressions are equal to 136. But in question value is given as 157 so it is false statement
Answer:
4 dimes and 8 quarters
Step-by-step explanation:
Let d = number of dimes.
Let q = number of quarters.
d + q = 12
10d + 25q = 240
-10d - 10q = -120
(+) 10d + 25q = 240
---------------------------------
15q = 120
q = 120/15
q = 8
d + q = 12
d + 8 = 12
d = 4
Answer: 4 dimes and 8 quarters
