Answer:
x = or 0.706
or 1.735
Step-by-step explanation:
5x + 2y=7 ----->(eq 1)
- 2x + 6y=9 ----->(eq 2)
Multiply (eq 1) with 3
3×(5x + 2y) = 3×7
15x + 6y = 21 ----->(eq 3)
substract (eq 3) from (eq 2)
- 2x + 6y - (15x + 6y) = 9-21
- 2x + 6y - 15x - 6y = 9-21
- 2x - 15x + 6y - 6y = 9-21
-17x = -12
x = -12 ÷ -17
x =
put x = in (eq 1)
The right fraction represents the percentage; 42 over 100 (100 is the total), or 0.42.
The left fraction is the part number over the whole number. The whole number is unknown, so we use 'x'.
Your answer is 75.
function : y = (-x) - 6
<u>Find x-intercept</u> :
- (-x) - 6 = 0
- (-x) = 6
- x = -6
<u>Find y-intercept</u> :
- y = (-0) - 6
- y = -6
mark these two points on both the axis and draw a straight linear graph.
passes coordinates : (0, -6), (-6, 0)
