Answer:
(2n + k) - 7
Step-by-step explanation:
1. Let ''a number'' be presented as n
2. ''twice a number'' → 2
n
3. ''twice a number and k'' → 2n + k
4. 7 less than twice a number → (2h + k) - 7

Answer:
y + 13 = 5(x + 2)
Step-by-step explanation:
The slope-intercept form of the equation of a line is
y = mx + b,
where m = slope, and b = y-intercept.
From the slope-intercept equation y = 5x - 3, we see that the slope of the line is 3.
The point-slope form of the equation of a line is:
y - y1 = m(x - x1)
where m = slope, and (x1, y1) is a point on the line.
We have point (-2, -13), so x1 = -2, and y1 = -13.
We also have slope 5, so m = 5.
Now we use the coordinates of the given point and the slope in the point-slope equation.
y - (-13) = 5(x - (-2))
We simplify to get
y + 13 = 5(x + 2)
Speed is distance over time. There’s no distance in the question and the time is 1 hr 30 mins hence 1.5 hours.
Answer:$29.12
c+0.04c (which can also be written as 1.04c, as they are like terms)
(28)+0.04 x (28)
28 + 1.12
=$29.12
