Answer:
y = -1/4x + 2.5
or
y = -1/4x + 5/2
Step-by-step explanation:
First we know that a perpendicular line is one that intersects at a 90-degree angle. This is simply the negative inverse of the slope in our case. So, 4 turns into -1/4 and that is our new slope. Next we know that we want it to pass through the point (6,1). Right now our equation is y = -1/4x + b. We can plug (6,1) into this equation and solve.
1 = -1/4(6) + b
1 = -6/4 + b
4/4 + 6/4 = 10/4
10/4 = b
simplify: 5/2 or 2.5 = b
Now we have our y-intercept, so we can complete our equation.
y = -1/4x + 2.5
or
y = -1/4x + 5/2
Answer:
-8a - 7b - 7c
Step-by-step explanation:
-8a - 2b - 10c - (5b - 3c)
Negate 5b and -3c
-8a - 2b - 10c - 5b + 3c = -8a - 7b - 7c
-2 then -5/2 and then 1.7

you turn them to a decimal to make them easier and then divide them to get the answer.
Answer:
250
Step-by-step explanation:
First with factorise the common factor out first, in this case, its 25.
25x6+25x4 = 25(6+4)
Now using of order of operations we will evaluate the bracket first.
25(6+4) = 25(10) = 25 x 10 = 250
