Answer:
0.57 14.5/25 57%
Step-by-step explanation:
decimal fraction percent
Find slope of line A:
Move into slope-intercept form y = mx+b
<span>5x + 8y = -9
8y = -5x - 9
y = (-5/8)x - 9/8
The slope of line A is -5/8.
If </span><span>Line B is perpendicular to line A, then
slope Line B = negative reciprocal of slope Line A</span>
<span>slope Line B = 8/5
So like B has the equation
y = (8/5)x + b
If it passes through (10,10), we know that when x = 10, y = 10. Use those values to solve for b:
</span>
<span>y = (8/5)x + b
10 = (8/5)·10 + b</span>
<span>10 = (8)·2 + b
10 = 16 + b
b = -6
So line B has equation </span>
<span>y = (8/5)x - 6
m = 8/5 and b = -6
so
m + b = 8/5 - 6 = 8/5 - 30/5 = -22/5
So m+b = -22/5 or -4.4 in decimal form

Answer:
2x+1+x+1+x+x+2+x+x+1+2x+1+x+1+x+2+x+1
= 12x+10
Answer:
4 donuts per minute/(donutes is that a typo?)
Step-by-step explanation:
if a bakery can make 60 donuts in 15 minutes, that is 60 donuts/15 minutes.
to reduce this fraction, the top and bottom can be divided by 15 to get 4 donuts/1 minute.
The answer is 4/10*cos 01
