Answer:
The slope is 4...
Step-by-step explanation:
y = mx + c
y = 4x
compare both..
Answer:
a. y= -5/2x -4
Step-by-step explanation:
An equation that is perpendicular to another equation must have the opposite slope. In other words, the perpendicular equation will be the opposite sign & the reciprocal of the equation it is perpendicular to. In this case, the perpendicular slope is -5/2x. Therefore, the only answer possible is a.
Answer:
d
Step-by-step explanation:
because think about it for a little bite when it says four times the difference that means it 4(n-16).
Answer:
1:12:4
Step-by-step explanation:
We let the youngest, George, age be x
From the question Alex is 12 years older than George.
This implies that,in terms of x, Alex's age is x+12
Also,Carl is three times older than Alex
This implies that, in terms of x Carl's age is 3(x+12)
The sum of their ages is 68
This implies that

we simplify to get the value for x


subtracting 48 from both sides


Dividing through by 5


Hence George is 4yrs old,Alex is 16 yrs old and Carl is 48 yrs old.
Therefore the ratio of George’s age to Carl’s age to Alex’s age is 4:48:16=1:12:4
