Answer:
As you can see, x is a variable in both 3x 2 and 7x, and the variable x is multiplied by a number. In the first term, 3x 2, 3 is multiplied by the variable, so 3 is a coefficient. With 7x, 7 is multiplied by the variable. 7 is therefore a coefficient.
Substitute "d" = 2, 3.5 and 5 in the given equation and solve to get the "W" values for the respective days. Then plot the graph using days "d" in the "x" axis and weight "w" in the "y" axis the graph will be most definitely "Linear".
18x+90=180
-90 -90 Subtract 90 from both sides
__________
18x=90
/18 /18 Divide 18 on both sides
__________
x=5
Answer:
On May 1st, the temperatures at midnight in five European cities were measured and the results were as follows.
Glasgow 2°C, Nice 6°C, Berlin 0°C, London 4°C,
Oslo -3°C List the cities in order of the temperature at midnight, starting with the lowest.
Answer:
D. x ≥ -13/2 or x < -41/6
Step-by-step explanation:
- 5/2+x ≥ 1/3 ⇒ x ≥ 1/3 -5/2 ⇒ x ≥ - 13/2
or
- x+2 < -29/6 ⇒ x < -29/6 - 2 ⇒ x < -41/6
So combined the answer is:
Option D is correct
