In an auditorium, the first row of seats has 30 seats. each row behind the first row has 4 more seats then the row in front of i

Alexeev081 [22]

Answer:

126

Step-by-step explanation:

Row 1: 30+0*4

Row 2: 30+1*4

Row 3: 30+2*4

...

The list goes on. Do you see a pattern here? If we call the row number as r, the formula is 30+(r-1)*4. In the 25th row, the r is 25. So in the formula, it is 30+(25-1)*4=30+24*4=126.

I hope that helped.

Donald's Earnings, x (dollars) Fallons Earnings, y 38 45 43 50 48 55 53 60 58 65 Which equation best represents Fallon's earning

kherson [118]

Given:

The table of values for Fallon's earnings in terms of Donald's earnings.

To find:

The equation that best represents Fallon's earnings in terms of Donald's earnings.

Solution:

In the given table the x-values are increasing by 5 units and y values increasing by 5 units. It means the rate of change of y with respect to x is constant and the table represents a linear function.

If the graph of a linear function passes through two points, then the equation of linear function is

$y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)$

Consider any two points from the table. Let the two points are (38,45) and (43, 50). Then, the equation is

$y-45=\dfrac{50-45}{43-38}(x-38)$

$y-45=\dfrac{5}{5}(x-38)$

$y-45=1(x-38)$

$y-45=x-38$

Adding 45 on both sides, we get

$y=x-38+45$

$y=x+7$

Therefore, the correct option is A.

How can I solve this equation 6+7x=55

lorasvet [3.4K]

You could solve it with these two steps:

#1). Subtract 6 from each side of the equation.
and then
#2). Divide each side by 7.

If you'll do that, the solution will be right there on the paper in front of you.
It'll begin with "x =", and right after that will be the value of 'x'.
