Answer:
7
Step-by-step explanation:
Trial and error. Start with 1 and go to 9
x-intercept is for y = 0
y-intercept is for x = 0
We have x - 3y = -9.
Put y = 0 to the equation:
x - 3(0) = -9
x - 0 = -9
x = -9
Put x = 0 to the equation:
9 - 3y = -9
-3y = -9 <em>divide both sides by (-3)</em>
y = 3
Answer:
<h3>x-intercept (-9, 0); y-intercept (0, 3)</h3>
26 = 5 (x + 10) + 3x
26 = 5x + 50 + 15x
26 = 5x +15x + 50
26 = 20x + 50
26 - 50 = 20x - 50
-14 = 20x
-14 / 20 = x
-0.7 = x
