An inequality that can be used to describe this situation would be;
A. |t - 2| < 4
-2 is the fall in temperature, whereas the overall temperature should be less than 4.
Answer:
y = 2x + 7
Step-by-step explanation:
→ Find the gradient
→ Write into y = mx + c format
y = 2x + c
→ Substitute in x = -1 and y = 5
5 = -2 + c ∴ c = 7
→ Write into y = mx + c format
y = 2x + 7
Answer:
d = 8.6
Step-by-step explanation:
a^2 + b^2 = c^2
7^2 + 5^2 = c^2
49 + 25 = c^2
74 = c^2
Now you take the square root of 74 and c^2
If you put the square root of 74 in a calculator you get about 8.6
So c = 8.6 or d = 8.6
Answer:
3/4,18/24
Step-by-step explanation:
You can mutiply the numerator and denominator by the same number or divide it by the same number as long as it is a whole number. Ex. (9/3) over (12/3)=3/4. Or (9x2)/(12x2)=18/24
