Hello :
let the equation : y = ax+b
<span>xx-intercept (4.5,0) : 0 = a(4.5) +b .... (1)
</span><span>yy-intercept (0,-5.4) .: - 5.4 = a(0)+ b .....(2)
by (2) : b = - 5.4
subsct in (1) : 4.5a -5.4 = 0
a = 5.4/4.5
a = 54/45
a = 6/5
</span><span>the equation of the line (in slope intercept form) is : y =(6/5)x - 5.4</span>
Answer:
0.47
Step-by-step explanation:
- 4.2/9 is 4.66 repeating
- Hundredth means anything after the 6
- Which means 7
- So answer is 0.47
Answer:
26. A
27. A
Explanation:
Answer:
The Terry's resultant speed is 27mi/h
Direction of ferry=20°
Step-by-step explanation:
(-25,0) + ( 0, 9)= (-25, -9) is the vector representing the movement of the ferry
Speed of ferry = sqrt[(-25)^2 + (-9)^2]
Speed= sqrt (-625 + (-81))
Speed= sqrt(-706)
Speed=26.57mi/h
Nearest tenth,speed= 27mi/h
Tanz° = (-9/-25)
Tanz°= 0.36
Z°= tan^-1 0.36
Z= 19.80°
Nearest tenth,z=20°
Answer:
yes, yes, no
Step-by-step explanation:
1. L= i + 2j +k; P = -3i + j + k, line lies on one another at k
2. L =i + 2j + k and P = 6i -3j + k, the lines lie on one another at k
3. P = ai + bj and -2bi +2aj + (a+b) k
