Answer:
TS = 22
x = 49
Step-by-step explanation:
(5x-2)/39 = (3x+1)/26
Multiply both sides by 78:
10x-4 = 9x+3
x=7
3x+1 = 22
:::::
(x+5)/36 = 30/20
x+5 = 54
x = 49

<h2>
Step-by-step explanation:</h2>
Graph B consists of a parabola that opens downward. If a parabola opens downward, the the coefficient of x will be negative.
<h2>More details:</h2>
There is an easy way to tell whether the graph of a quadratic function opens upward or downward: if the leading coefficient is greater than zero, the parabola opens upward, and if the leading coefficient is less than zero, the parabola opens downward.

Answer:
325
The value of the expression 5x – 2y + (7x – y) when x = 7 and y = -2 is 90
<h3>How to evaluate the expression?</h3>
The expression is given as:
5x – 2y + (7x – y)
Substitute x = 7 and y = –2 in the above expression
5 * 7 - 2 * -2 + (7 * 7 + 2)
Evaluate the expression
90
Hence, the value of the expression 5x – 2y + (7x – y) when x = 7 and y = -2 is 90
