Answer:
(1) 56 miles/hour
Step-by-step explanation:
We need to find the average rate of change from t = 2 to t = 9.
At t = 2 hours, d = 106 miles.
At t = 9 hours, d = 498 miles.
The average rate of change in function f(x) from x = a to x = b is
[f(b) - f(a)]/(b - a)
average rate of change from t = 2 to t = 9 =
(498 - 106)/(9 - 2) = 392/7 = 56
Answer: (1) 56 miles/hour

Answer:
y = -1/5x -1
Step-by-step explanation:
When given 2 points, it can work well to start with the 2-point form of the equation for a line.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (0 -(-2))/(-5 -5)(x -5) +(-2)
y = 2/(-10)(x -5) -2
y = -1/5x -1 . . . . . eliminate parentheses and collect terms

m<GFD = 50°
m<CFD = 40°
Segment FD doesn't bisect <CFG because the angles aren't equal.
Step-by-step explanation:
<CFD and <GFD are complementary angles and their sum is 90°
-5x + 5 -7x + 1 = 90° add like terms
-12x + 6 = 90
-12x = 84 divide both sides by -12
x = -7
m<CFD is -5x + 5 ➡ (-5)×(-7) + 5 = 40°
m<GFD is -7x + 1 ➡ (-7)×(-7) + 1 = 50°

Tell whether the x- and y-values in the table show a proportional or non-proportional relationship. If the relationship is proportional, tell the rule. Select one:
aProportional; x = 3/7y
bNon-proportional
cProportional; x=1/3y
dProportional; x=2/5y
Answers
Answer:
b. Non-proportional
Step-by-step explanation:
A table of values that represents a proportional relationship will have the same ratio of every pair in the given table. That is, y/x will result in the same value all through for every given pair.
The table of values given does not show a proportional relationship, because the ratio of y to x of each given pair of values are different and unequal:
y/x = 3/1 ≠ 5/2 ≠ 7/3 ≠ 9/4
Therefore, it is non-proportional.
Order these numbers from least to greatest.

Reduce the fraction to the lowest term
[tex] \frac{4}{8} [/tex]
Answers
Answer:
[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
To reduce the fraction to the lowest term, we divide the like term by the GCF of its numerator and denominator.
Here,
As 4 and 8 have the GCF as 4 itself. We divide both the numerator and denominator with the GCF (4).
Hence,
[tex]\frac{4}{8}\\=\frac{4}{8}/\frac{4}{4} \\=\frac{4/4}{8/4} \\=\frac{1}{2}[/tex]
