hey there!!
Given :
f ( x ) = l 2x - 4 l , find f ( - 7 )
We will have to substitute the value of -7 instead of x
f ( -7 ) = l -14 - 4 l
f ( -7 ) = l -18 l
As the value in a mod shall always be positive, the answer would become 18
Hence, the required answer is 18
Hope my answer helps!!
Idk but haha hello why not but why
Answer:
(-3,3)
Step-by-step explanation:
Using elimination:
Multiply the first equation by 8 and the second by 5 which equals
40x+56y=48
-40-60y=-60
Now you add them together
40x+(-40x)=0 so that crosses out
56y+(-60y)= -4y
48+(-60)=-12
You now have -4y=-12
Divide by -4
y=3
Now plug in y to any of the equations
5x+7(3)=6
5x+21=6
Subtract 21 from both sides
5x=-15
Divide by 5
x=-3
Your final solution is (-3,3)
Answer: solve the expression by applying BODMAS, then multiply 8 by 2
Step-by-step explanation:
The first operation is to apply BODMAS, then solve the expression in the bracket
3,500÷(34+8×2)−4
3,500÷ (34 + 10) -4
3500 ÷ 44 - 4
3500 ÷ 40
87.5
I hope this helps.
Yes I’d the answer and it’s D
