Hi friend,
Capital City's population would be B) 2240
The given proportional relationship is y = -5x.
Therefore the ratio
y/x = -5 = -5/1
If x changes by 1, then y/x = y/1 = -5.
This means that y changes by -5 when x changes by 1.
The ratio of vertical change is -5:1
The standard equation for a straight line is
y = m*x + c
where
m = the slope,
c = the y-intercept.
Therefore the given relationship is a straight line with a negative slope of -5. This means that y decreases as x increases.
Answer: C
-5:1
The graph decreases from left to right.
Answer: See picture.
Step-by-step explanation:
For this king of method, I personally like using the Box Method. See Picture:
Answer:
Step-by-step explanation:
3). Naomi walked 4560 m to the nearest 10 m. Peta walked 4600 m to the nearest 100 m.
a). 4555 m ≤ n ≤ 4564 m
4550 m ≤ p ≤ 4649 m
b). If n = 4555 m and p = 4550 m
Then Naomi walked more than Peta
If n = 4555 m and p = 4555 m
Then Both Naomi and Peta walked exactly the same.
If n = 4555 m and p = 4649 m
Then Peta walked further than Naomi.
Therefore, all three statements could be true.
4). (a). x = 120 to nearest 10 → 115 ≤ x ≤ 124
(b). y = 1.24 to 2 decimal places → 1.24
(Already given in 2 decimal places)
(c). z = 0.0124 to 3 significant numbers → 0.0124
Answer:
a: $392.28
b: $112.08
Step-by-step explanation:
The decimal form of 40% is 0.4. Multiply 0.4 by 280.20, and you get 112.08
Because it is a markup, you add this 112.08 to your original price, 280.20
280.20+112.08=392.28
Your answer to letter a is $392.28
The rate of the markup is how much was added, so 112.08
