Answer:
Y=2x+7
Step-by-step explanation:
To find the gradient of the line u have to subtract the y intercepts and the x intercepts
11--9/2--8=20/10=2
Y-11/x-2=2
Y-11=2(x-2)
Y-11=2x-4
Y=2x-4+11
Y=2x+7
Answer:
-56
Step-by-step explanation:
f(x) = 7x + 7
x = -9
We meed to plug in x = -9 into the first equation:
f(-9) = 7(-9) + 7
We can open up the parentheses:
f(-9) = -63 + 7
And then simplify:
f(-9) = -56
The answer is a I believe
I hope this helped :)
Answer:
the two numbers are 16 and -25
Step-by-step explanation:
Let the two numbers be x and y
x+y=-9
x-y=-41
By substitution
y=-9-x
x-(-9-x)=-41
x+9+x=-41
2x=-41-9
2x=-50
x=-25
y=-9-(-25)
y=16
