Answer:
No, the absolute value of a number is different from the opposite.
Step-by-step explanation:
For example, the absolute value of 4 is 4.
l4l = 4
But the opposite of 4 is -4.
Absolute value is ALWAYS positive, but the opposite of a positive number is a negative number.
Answer:
-4
Step-by-step explanation:
16-20 = -4
Answer:
(a)
Step-by-step explanation:
To determine if the points are a solution to the equation.
Substitute the coordinates of the point into the left side of the equation and if equal to the right side then they are a solution.
(2, 5)
- 3(2) + 4(5) = - 6 + 20 = 14 ← True
(4, 6)
- 3(4) + 4(6) = - 12 + 24 = 12 ← False
Thus (2, 5) is the only solution to the equation → (a)
Answer:
y= ¾x +6
Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.
Let's find the gradient first.
Using the formula above,
subst. the value of m into the equation.
To find c, substitute a coordinate.
When x=0, y=6,
Thus, the equation of the line is 
.
N/5 + 9 = 22
5(n/5 + 9 = 22)
n + 45 = 110
n = 65
