Answer:
y = 3x - 5
Step-by-step explanation:
Slope = 3
x-intercept (what the value of y is when its 0) = -5 so y = 3x - 5
Answer:
-x - 4
Step-by-step explanation:
(x + 1) - (2x + 5)
Distribute the - sign into (2x + 5). When you do so, the positive sign will change to negative sign
We have
x + 1 - 2x - 5
Rearrange the expression
x - 2x + 1 - 5
-x - 4
Answer:
1 1/3
Step-by-step explanation:
make both into improper fractions
3 3/5= 18/5
2 7/10= 27/10
then divide
18/5÷27/10
= 18/5×10/27
= 36/27
simplify the fraction
= 12/9
= 4/3
= 1 1/3
Let Rs.x and Rs.y be the cost of a knife and a spoon respectively.
From question,
x = 2y --- (1)
and,
12x + 8y = 46.08
=> 12×2y + 8y = 46.08
=> 24y + 8y = 46.08
=> 32y = 46.08
=> y = 46.08/32
=> y = 1.44
putting y = 1.44 in (1)
=> x = 2×1.44
=> x = 2.88
Therefore, cost of a knife is Rs 2.88
<span>Net change basically means that when you're done with EVERYTHING, how far did you move from the beginning. </span>
So in this case, let's say that you started up on the 1st floor, you went up to the 5th, down to the 2nd level of the garage, up to the 1st again then up to the 2nd floor. You started on the 1st floor and ended up on the 2nd floor, so the NET CHANGE is 1 floor up. sound clear?
