To solve the set of equations given above, we can use the substitution method where we substitute one equation to the other and solving for one variable. We do as follows:
<span>0.4x - 0.1y = 2
x = 5 + 0.25y
0.2x + 0.5y = 1
</span>0.2(5 + 0.25y)+ 0.5y = 1
y = 0
x = 5
Therefore, the correct answer from the choices is option A, (5,0).
Answer:
The number is 4
Step-by-step explanation:
17 - 5 = 12
12 ÷ 3 = 4
Answer:
-3(3+4x)
Step-by-step explanation:
Answer:
y = -⅓x + 3
Step-by-step explanation:
To find the equation of the graph in the form of y = mx + b (slope-intercept form), we have to find the slope (m) and the y-intercept (b) of the graph:
Slope (m) = change in y/change in x
Slope (m) using the two points on the line, (0, 3) and (3, 2):
m = (2 - 3)/(3 - 0) = -1/3
m = -⅓
y-intercept (b) = 3 (the y-axis is intercepted at this point)
✔️To write the equation, substitute m = -⅓ and b = 3 into y = mx + b:
Thus,
y = -⅓x + 3
