A rhombus is a quadrilateral which all sides are congruent and opposite sides are parallel.
So the sum of 4 times a number (4 times x or 4x) and 7 (+7) is (=) 19 (19)
4x+7=19
subtract 7 from both sdies
4x=12
divide by 4
x=3
the number is 3
Answer:
Step-by-step explanation:
To find the inverse function, the first step we do is change f(x) to Y. So now, we have
y=2x+1
Now that we have this function, we simply flip x and y. When we do that, we get
x=2y+1
Now that we have this function, we just solve for Y. We do that by bring 1 to the other side by subtracting it from both sides, then dividing both sides by 2.
x-1=2y+1-1
x-1=2y
(x-1)/2=2y/2
(x-1)/2=y
So, our inverse function is:
y=(x-1)/2, or y=x/2 - 1/2
