Answer:
y= -2x+1
Step-by-step explanation:
y=mx+b
y= -2x +b
3= -2(1) +b
3= -2 +b
b=1
y= -2x+1
Answer:
Step-by-step explanation:
a)
d=0.68t + 1.5 if t time is 3 hrs
d=0.68(3) + 1.5
= 2.04 + 1.5
d= 3.54 ft
b)
d=0.68t + 1.5 if d depth is 4 ft solve for t
d - 1.5 = 0.68t
(d - 1.5) / 0.68 = t
(4 - 1.5) / 0.68 = t
t = 2.5/0.68
t = 3.68 ft
c) I needed to bury my moth..... cat.
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
Parallel lines can be distinguished by looking at the value of their slopes. These equations should have the same value of the slope. We are given the equation,
<span>y=-3x+5
From the choices, we see that A, C and D have the same slope with the equation. Therefore, the correct answer is B, it is the equation that can't be parallel with the given equation.</span>
