Answer:
Just substitute each number into the expression:
5(5) - 6(3) + 20(1/4)/4(3)(1/4) = 25 - 18 + 5/3 = 7 + 5/3 = 26/3 or 8 and 2/3.
Step-by-step explanation:
this equals 3 + 16 / 4
The division is done first so its
3 + 4
= 7 answer
2) mx - y = 2*7 - 5
= 9 answer
Answer:
The value of x if the equation is
3x + 4y=65
x = 49/3 or 16.3
&
3x - 4y=65
x= 27
It’s b for sure if I’m wrong then it’s a
Answer:
y=x+15
Step-by-step explanation:
1. find the slope
m=(24-19)/(9-4)
m=5/5
m=1
2. plug slope into slope intercept formula
y=1x+b
y=x+b
3. plug in for x and y from either coordinate point (just make sure they are from the same point!!)
24=9+b
15=b
4. plug m and b into formula
y=x+15
