Answer:
Sample response:
To determine the relationship between quantities, you must determine what to do to the x-values to make them into y-values. The correct operation must turn every x-value into the corresponding y- value in the table. Once you know the relationship, you can use the same operation on all of the x-values that have unknown y-values.
OR:
In a table to get from x to y you have to multiply by a number. To find this you must divide x by y or y by x. So to get the missing quantities you must multiply the last known number by the number you found by dividing.
350 inches squared is the answer, because this problem is asking for the surface area. If it was asking for the volume it would have to be asking how much space the cake was taking up, but instead it is asking how much frosting is covering the cake, minus the bottom, aka. the surface are.
you can look at the above photo
The equation of a line in slope-intercept form is equal to
y=mx+b
where
m is the slope
b is the y-intercept
we have
m=-5/2
point (4,-3)
substitute in the expression above
-3=-(5/2)(4)+b
solve for b
-3=-10+b
b=10-3
b=7
therefore
the equation of the line is
<h2>y=-(5/2)x+7</h2>
Let n = 30
We are actually looking for a_30.
a_30 = 4(30) + 1
a_30 = 120 + 1
a_30 = 121
