Answer:
(4,1)
Step-by-step explanation:
Using substitution you can determine that 2*4-7 is in fact equal to 1
Just solve your question for y:
2x + y = 12
y = 12 - 2x
thats the same as
y = -2x + 12
and you know that if y = -2x + 12, it can't equal -6-x
Answer:
1: 250 000
( There are 1000 metres in a km and 100 cm in a m, thus you multiply 5 km by 100 000 to convert it to cm, then you divide by 2 in order to get the simplist form of the ratio )
We are asked to determine x from the function sin x = sqrt 3/2. In this case, the right hand side number belongs to the 30-60-90 triangle. Using a calculator, in degrees mode, we input in the calculator, arc sin sqrt 3/2 equal to 60 degrees or 120 degrees since it can be in quadrants 1 or 2.
