Answer:
its 2,400
Step-by-step explanation:
Answer:
h = 3
k = -2
r = 2
Step-by-step explanation:
The numbers inside the parentheses are the opposites of the values h and k.
For the radius, we look at the constant on the other side of the equation and square root that. In this case, the square root of 4 is 2.
45machines:20mins
20mins=1/3hour
45machines:1/3hour
times 3
135machins=1hour
135machines per hour
B. 30 in 15
15=1/4 hour
30=1/4hour
times 4
120machines per hour
both produce for 2 hours
A. is 135*number of hours, B is 120 times number of hours
135*2+120*2=
270+240=
510
make 510 machines in 2 hours
Answer:
y = 4x + 1
Step-by-step explanation:
1. Solve given equation for y
4x-y=2
4x=y+2
y=4x-2
2. Parallel in linear equations means the new line will have the same slope, so your new equation so far is
y=4x+b (formula being used is linear function y=mx+b)
3. (-1,-3) is a coordinate (x,y), so plug those values in for x and y so the only variable in your equation is b, the y-intercept
-3=4(-1)+b Solve for b
-3=-4+b
1=b
4. Rewrite your new equation with the m and b you now know
y=4x+1
Answer:
280.006
Step-by-step explanation:
34,234 can also be written as 34,234.000
34,514.006 - 34,234
= 34,514.006 - 34,234.000
= 280.006
