Answer:
2.52.
Step-by-step explanation:
If one number is x then the other = 3x/8.
Also x - 3x / 8 = 4.2
x - 0.375 x = 4.2
0.625x = 4.2
x = 4.2 / 0.625
x = 6.72.
So the lesser number is 6.72 * 0.375 = 2.52.
Answer:
D
Step-by-step explanation:
To find the intercepts, that is where the line crosses the x and y axes
• Let x = 0, in the equation for y-intercept
• Let y = 0, in the equation for x- intercept
x = 0 : - 3y = - 9 ⇒ y = 3 ⇒ (0, 3) ← y- intercept
y = 0 : x = - 9 ⇒ (- 9, 0 )← x- intercept
Answer:
