SOLUTION
If the table represents an inverse variation, it means that y is inversely proportional to x, written as
Removing the proportionality sign and introducing a constant k, we have
In the first column, we have x = -4 and y = 3.5. Substituting these values for x and y, we have
So, if it's an inverse variation, the relationship would be
In the second column, x = -2 and y = 7.
Now lets substitute the value of x for -2. If we get y to be 7, then the relationship is an inverse variation
We have
Since we got y = 7, the relationship is therefore an inverse variation.
The constant k = -14
The equation for the inverse variation is
Answer is 74. Greater than 70 less than 80 so some where in the 70s. It has 4 ones so it would be 74.
Answer:
B. n-3
Step-by-step explanation:
If x is an even integer, the next consecutive even integer = x + 2
Since (n-5) is even, the next consecutive even integer = (n-5) + 2 = n-3
We need to find the percent, let's start but making the equation.
The price is 2.69
The tax cost is 0.13
So what percent of 2.69 is = 0.13.
Equation: X/100 x 2.69 = 0.13
Multiply each side by 100 so we can get x alone with the price: 2.69x = 13
Now to get x alone, we must divide both sides by 2.69: x = 4.8
Finally, we just round 4.8 to the nearest whole number, which is 5 (5 or above give it a shove, 4 or below let it go, we have 8 so we give it a shove). This means that the answer will be 5%.
I hope this helps! :)
Okay i believe the first one is 4/7 and the second one is 2. also don’t listen to them. sometimes it can be hard and you start to stress. good luck and if this isn’t right i’m so sorry :) keep your head up!!!
