I hope this helps you
x'=1 y'=4 slope = -3
slope. (x'-x)=y'-y
-3. (1-x)=4-y
-3+3x=4-y
y=4+3-3x
y=7-3x
Answer:
11
Step-by-step explanation:
If we input 11 into the equation, we get: 10 + 5(11) = 65.
5 x 11 = 55
55 + 10 = 65
Therefore x = 11
Answer:
17 cm
Step-by-step explanation:
To find the perimeter of any figure, you must add all the side lengths. In a triangle, there are three side lengths to add, and in this case, they are 3 cm, 6 cm, and 8 cm long. So:
3 + 6 + 8 = 17 cm
∴, the triangle's perimeter is 17 cm.
Answer:
33cm
Step-by-step explanation:
385 / 35 = 11
11 times 3 = 33
Answer:
y = 9x + 175
Step-by-step explanation:
Choose one value for y in the table, for example, 211. All the equations have 9x, so multiply the corresponding x for 9:
9•4 = 36
Now make the value of y - 36:
211 - 36 = 175
Now you have the equation:
y = 9x +175
