-3 will be your slope and your y-intercept will be -2... equation i: y=-3x-2
Answer:
a. 85 m
b. 96 cm
Step-by-step explanation:
Work for (a.)
- 95 x 2 = 190.
- 360 - 190 = 170
- 170 ÷ 2 = 85
- Final Answer: 85 m
Work for (b.)
- 58 x 2 = 116
- 5568 ÷ 58 = 96
- To make sure: 96 x 58 = 5568
- Final Answer: 96 cm
Add 7 on both sides then multiply by 2 to isolate m, and you should get m=4, so the answer is
the last option.
Hope this helped :)
Answer : 11 and 13
Step-by-step explanation:
Let the numbers be X and Y then,
By question
X= Y - 2 .....................(i)
2Y = 3X - 7 ...............(ii)
putting the value of X from (i) on equation (ii) we get,
2Y = 3(Y - 2) - 7
2Y = 3Y - 6 - 7
2Y - 3y = - 13
-Y = - 13
Y = 13
now putting value of Y in equation (i)
X = 13 - 2= 11
hence those numbers are 11 and 13 respectively
