Olivia bought a rose gold chain. Wants to buy decorate of beads to put on the chain. The equation below can be used to determine y, Livius total cost in dollars to buy a rose gold chain and x decorate beads. f(x)=1.75x+9.50
A. use the equation to determine Olivia‘s total cost if she buys 15 beads and 40 beads you must show all your work and explain your steps
B. what does the 1.75 in the equation represent explain your reasoning
C. what does the 9.50 in the equation represent explain your reasoning

Help please I’ve been trying to figure this out for 20 minutes!!!

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

95.03 is the answer. hope this !

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
