Answer: 75
Step-by-step explanation: 100 / 20 =5
15x 5= 75
Answer:
y=-3x-5
Step-by-step explanation:
given equation:
3y=x-4
slope intercept form is y=mx+b
(m is the slope, b is the y intercept)
divide by 3
y=1/3x-4/3
perpendicular lines have slopes that are negative and reciprocal. If you multiply them together, the result is -1.
so to find the slope of the perpendicular line, use this equation:
1/3m=-1
multiply by 3
m=-3
the slope of the new line is -3.
here is our equation so far:
y=-3x+b
now, we need to find b.
Since the equation of the line passes through the point (-2,1) we can substitute that into the equation to find b
1=-3(-2)+b
multiply
1=6+b
subtract 6
-5=b
so the line is y=-3x-5
Hope this helps!
Answer:
It's gonna be C
Step-by-step explanation:
No explanation it's C.
Let n = the unknown number
"the difference between a number and 11" translates to n - 11
"3 more than half the number" translates to 1/2n + 3
The word "is" becomes the equal sign.
n - 11 = 1/2n + 3
