Answer:
y = 9x/5 + 50
Step-by-step explanation:
We are represent the information as coordinate (x,y)
If the cost for an order of 100 kilograms of steel bars is $230, this is expressed as (100, 230)
Also if the cost for an order of 150 kilograms of steel bars is $320, this is expressed as;
(150, 320)
Find the equation of a line passing through the points. The standard form of the equation is expressed as y = mx+c
m is the slope
c is the intercept
Get the slope;
m = y2-y1/x2-x1
m = 320-230/150-100
m = 90/50
m = 9/5
Get the y-intercept by substituting m = 9/5 and any point say (100, 230) into the expression y = mx+c
230 = 9/5(100)+c
230 = 9(20)+c
230 = 180 + c
c = 230-180
c = 50
Get the required equation
y = mx+c
y = 9/5 x + 50
Hence an equation for the cost of an order of steel bars (y) in terms of the weight of steel bars ordered (x) is y = 9x/5 + 50
Answer:
x = 6
Step-by-step explanation:
we can multiply the entire equation by 3 to simplify the numbers
-2x + 27 = 4x - 9
27 = 6x - 9
36 = 6x
x = 6
Answer:
A ans. No it is binomial factor because it contain two terms
B and.
Importance must always be given to all the information's that are already given in the question. Based on those information's the answer to the question can be easily deduced.
Number of Hamburgers eaten by Justin in 10 minutes = 15
Then
The number of hamburgers eaten by Justin in 1 minute = 15/10
= 1.5
So option "B" is the correct option among all the options given in the question. It can seen from the deduction that Justin can eat 1.5 hamburgers in 1 minute. I hope the procedure is clear enough for you to understand.
