Thus is how you write y=2x-7 in a function notation. ANSWER:F(x)=2x-7.
0.134 = 134/1000 = 67/500
Answer:
They are 192 km apart.
Step-by-step explanation:
? = unknown value
We can use the equation
? km = ?cm * 8
Or ratio
1/8 (What do you multiply 1 by to get to 8? 8. 1 is how many cm there are so if there are 24 cm then we multiply that by 8 as well.)
We have to multiply 24cm by 8 because of the ratio 1:8, 24 times 8 is 192.
You need to use all of them until you find the answer so lets fo this!
a. (-10,-12) x=-10 y=-12
3x+2y=6
3*(-10)+2*(-12)=6
-30-24=6
-54=6
This is incorrect,now we try the othe options
b.(10,12) x=10 y=12
3x+2y=6
3*10+2*12=6
30+24=6
54=6
This is incorrect then we try the other option
c. (-10,12) x=-10 y=12
3x+2y=6
3*(-10)+2*12=6
-30+24=6
6=6
And this is the correct answer. So the answer is c. (-10,12)
