The amount of books Matt had at the beginning (5) is a constant that does not change, thus nothing will be multiplied by that number. This eliminates options A and C, which both demonstrate 5 as being multiplied by the amount, x, of weeks.
As for the other two equations, which one makes sense for this problem, which models an increase of books over time? The equation with addition.
Answer:
<span>D. y = 5 + x
This problem shows the amount of library books Matt will have after any random amount of weeks he checked out one book, combined with the 5 he had before starting this pattern.</span>
Answer:
55.5 feet
Step-by-step explanation:
the scenario is attached in the form of a picture
We have to find h.
We will use the trigonometric ratio of tan to find the height of the house.
Hence the height of the house is 55.53 feet
Rounding off to nearest 10th
height = 55.5 feet ..
Answer:
the second one. They need to be in the same order of congruency.
Step-by-step explanation:
Xy= (10-3i)(3-10i)
=30-100<em>i- 9i+30i^2
=30^2-109i+30</em>
Answer:
x - 5y = 5
Step-by-step explanation:
Let's represent the equation of the graph in slope-intercept form, y = mx + b.
We'd need to find slope (m) and y-intercept (b) of the graph.
Slope (m) = ∆y/∆x
Using two points on the line, (0, -1) and (5, 0),
Slope (m) = (0 - (-1)) / (5 - 0) = 1/5
m = ⅕
y-intercept (b) is the point on the y-axis where the line intercepts the y-axis = -1
Therefore, b = -1
To write the equation, substitute m = ⅕ and b = -1 into y = mx + b
Thus:
y = ⅕(x) + (-1)
y = ⅕(x) - 1
Rewrite in standard form:
-⅕x + y = -1
Multiply both sides by -5
-⅕x*-5 + y*-5 = -1*-5
x - 5y = 5
