Question 2: 8t - 4v and -4v + 8t
Question 3: -e + 10k and 10k -e
Question 4: x = -3
Answer:
Since it is a simultaneous equation,
Using elimination method, Multiply equation 1 by the co efficient of x in equation 2 and multiply equation 2 by the co efficient of x in equation 1.

i think that A pair of an input value and its corresponding output value is called an ordered pair and can be written as (a, b). In an ordered pair the first number, the input a, corresponds to the horizontal axis and the second number, the output b, corresponds to the vertical axis.
We can thus write our values as ordered pairs
(0, 0) - This ordered pair is also referred to as the origin
(1, 2.5)
(2, 5)
(3, 7.5)
These ordered pairs can then be plotted into a graph.
Answer:
5
Step-by-step explanation:
y^1 = 5^1 (y = 5)
Anything raised to the power of 1 is just itself.
So, 5^1 = 5
Answer:
162 pieces
Step-by-step explanation:
Andrea has 18 yards
How many 4 inch pieces can she get?
Convert
1 yard = 3 feet
18 yards = 54 feet
1 foot = 12 inches
54 feet = 648 inches
Divide
648 inches ÷ 4 inches = 162 pieces
Hope this helps :)
