Answer:
40
Step-by-step explanation:
15 divided by 3 is 5
so each pound is 5 dollars.
now do 5 times 8
that gives you 40
the big bag is 40 dollars
Answer:
y = 2x + 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x + 3 ← is in slope- intercept form
with slope m = 2
Parallel lines have equal slopes, thus
y = 2x + c ← is the partial equation
Note this line passes through (0, 4) ⇒ c = 4
y = 2x + 4 ← equation of parallel line
Answer:
h(-3) = -5
Step-by-step explanation:
Replace a with -3 and simplify.
h(-3) = 2(-3) + 1
h(-3) = -6 + 1
h(-3) = -5
Answer:
5-a=2
Step-by-step explanation:
Answer:
The slope is the percentage of test score per number of days absent
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to
![m=\frac{y2-y1}{x2-x1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By2-y1%7D%7Bx2-x1%7D)
we have
y -----> is the percentage of test score
x ----> is the number of days absent
so
That means -----> The slope is the percentage of test score per number of days absent
In this problem the slope is negative
so
If the percentage test score increases----> the number of days decreases
If the percentage test score decreases----> the number of days increases
