Answer:
a = 43 / 30
Step-by-step explanation:
-7 ( 8a -9 ) = -23 + 4a
-56a + 63 = -23 +4a
-60a + 63 = -23
-60a = -86
a = 43 / 30
70/2 = 35
34 + 36 = 70
Hope this helps!
A linear<span> function is in the form y = mx + b or f(x) = mx + b, where m is the slope or rate of change and b is the y-intercept or where the graph of the line crosses the y axis. You will notice that this function is degree 1 meaning that the x variable has an exponent of 1.</span>
not imp u say this is triangle rect from the pythagore theorie then u say in a tr rec the angles other than the 90 degree one is 45 degrees
