Y int = (0,12)
Bc the y intercept is when X = 0
Slope =
(18-15)/(4-2) =
3/2
Answer:
D
Step-by-step explanation:
rise over run!
2x - 3 > 11 - 5x |add 3 to both sides
2x > 14 - 5x |add 5x to both sides
7x > 14 |divide both sides by 7
x > 2
x = 4
Answer:
x+b+2 * c - d
I believe that's the expression

Answer:
<h3>13 years</h3>
Step-by-step explanation:
Let the present age of Alicia be x
Let the present age of her brother be y
Three years ago;
Alicia age = x - 3
Her brother's age = y - 3
If three years ago Alicia was twice as old as her brother Carlos, then;
X - 3 = 2(Y-3)
x-3 = 2y - 6
x = 2y - 3 ...1
In two years time;
Alicias age = x+2
Her brother's age = y +2
If in two more years Alicia will be just 50% older than Carlos, then;
x+2 = y + 2 + (0.5(y+2))
x+2 = y+2 + 0.5y + 1
x+2 = 1.5y+3
x = 1.5y + 1 ...2
Equating 1 and 2;
2y - 3 = 1.5y + 1
2y - 1.5y = 1+3
0.5y = 4
y = 4/0.5
y = 8
Since x = 2y-3
x = 2(8) - 3
x = 16-3
x = 13
Hence Alicia will be 13 years old today
