Answer:
the answer is going to be B because that is the diamiter
We use proportion in this problem solving.
We know that 100% = 40.00 and 125%=x
I take 125% because the marks the price up 25%. So it is 100%+25%.
100x=40.00×125
x=40.00×125÷100
x=50.00
So the she sells the cell phone at 50.00
Answer: y=-4x+13
Explanation : because it is :)
Answer:
<h2>
y=(1/7)*x+(15/7)</h2>
Step-by-step explanation:
first, lets find the slope:
m=(y2-y1)/(x2-x1)
m=(3-2)/(6-(-1))
m=1/7
y=(1/7)*x+b
to find b lets pug in a point we know into the equation:
3=(1/7)*6+b
21/7=6/7+b
b=(21/7)-(6/7)
b=15/7
now we know the equation in slope intercept form representing this function is:
y=(1/7)*x+(15/7)
