Y intercept:
Y=-6-9(0)
=-6
(0,-6)
I’m assuming the slope is the gradient if that’s the case then it would be -9 since
Y=mx+c
m is the gradient and in this case it’s -9
Hello!
First do what is in parenthesis first
3 + [ -4 - 32]
Parenthesis again
3 + -36
Add
-33
The answer is -33
Hope this helps!
X=Tom´s age
y=Tim´s age.
we suggest this system of equations:
x+y=21
(x+3)=2(y+3)
We solve this system of equations by susbstitution method.
x=21-y
[(21-y)+3]=2(y+3)
24-y=2y+6
-y-2y=6-24
-3y=-18
y=-18/-3=6
x=21-y
x=21-6=15.
Answer: Tom is 15 years old, and Tim is 6 years old.
The answer is 4939.22 but i’m not sure what this is so the nearest hundredth lol sorry :(
