Answer:
x=16
Step-by-step explanation:
since y=7 when x=8 and your trying to find what x is when y=14. Your really just taking the y value which is 7 then multiplying it by 2 which is 14. then since you multiplied the first y value by 2 you then just multiply the 8 by 2 and that is 16.
To determine the inverse of a function, we first write the parent function in terms of y. So, in this part the x would be isolated to one side of the equation. Then, with the new form of the parent function, we switch the x into y and y to x. The new function would be the inverse function. For the given function, we do as follows:
<span> y=-4/x + 1
y - 1 = -4/x
x ( y - 1 ) = -4
x = -4 / (y -1)
Replacing x into y and y into x,
</span>y = -4 / (x -1)
<span>Therefore, the inverse is y=-a/x-b where a = 4 and b = 1.</span>
to solve you must dive 14 by 12 then simplify to the nearsest tenth.
Answer: a = 6
Step-by-step explanation:
2a - 8a = 12 - 8a
Add 8a to each side
10a - 8a = 12
Subtract 10a and 8a
2a = 12
Divide each side by 2
a = 6
10 - 6x = 160 - 10x
+6x +6x
-10 + 6 = -4
10 = 160 - 4x
-160
10 - 160 = -150
-4x = -150
-4x/4 = -150/-4
x= 37.5
