I attached a picture with the answer, hope this helps :)
the answer is a because the +2 is the why intercept.
LCD of 2/9x + 2/3x = 7/1 is gonna be 9 (u can put that 1 under the 7 if it helps u)
Hello here is a solution :
<span>3x + 5y = 78 .... (1)
2x - y = 0 ... (2)
from (2) : y = 2x
in (1) : 3x+5(2x) =78
13x = 78
x= 6
but : y =2x y=2(6) = 12
answer : x=6</span>
The rate of change of the function represented by the table is -2.5
<h3>Rate of change</h3>
The rate of change of a function is also known as its slope. The formula for calculating the slope is expressed as;
Slope = y2-y1/x2-x1
Using the coordinate point (1, -8.5) and (2, -6) as given in the table, the rate of change is expressed as:
Rate of change =-6-(-8.5)/2-1
Rate of change = -6+8.5/1
Rate of change = 2.5
Hence the rate of change of the function represented by the table is -2.5
