Answer: y = 2x - 11
Step-by-step explanation:
A linear equation has the following form.
y = a . x + b
where,
y: independent variable
a: slope
x: independent variable
b: y-intercept
The slope is 2, so a is 2. The ordered pair (4, -3) means that when x takes the value 4, y takes the value -3. We can replace these values in the general equation to find the y-intercept.
y = a . x + b
-3 = 2 . 4 + b
b = -11
The linear equation is
y = 2x - 11
Answer:
729 m³
Step-by-step explanation:
Volume of a cube (or a rectangular prism) formula:
lwh
l is length
w is width
h is height
Here, the length, width, and height measures 9 m.
So
9 × 9 × 9 or 9³ = 729
(-2/5)-(-1/8)
Need to make the denominators the same
(-16/40)-(-5/40)
Multiply -2/5 by 8
Multiply -1/8 by 8
-- sign= positive
-16/40+5/40
Answer=-11/40
20%=0.2
14*0.2 = 2.8 ( $2.80 is the tip she will be giving her)
$14+$2.80 = $16.80 ( what she will be giving in total)
$20-$16.80 = $3.20 (the change she will get back)
