7 / 8 = 0.875
It is a terminating decimal because the decimal has a finite amount of numbers.
Answer:
g(x) is translated 7 units right from f(x)
Step-by-step explanation:
Answer:
7x² - 7x + 15
Step-by-step explanation:
When we add two polynomial we add the co-efficient of the like terms. i.e., the coefficients of x², x and the constant term.
Given: f(x) = 4x² - 5x + 7
and g(x) = 3x² - 2x + 8
f(x) + g(x) = 4x² - 5x + 7 + 3x² - 2x + 8
⇒ f(x) + g(x) = 7x² - 7x + 15
Hence, the answer.
The scale of the graph makes it difficult to read the y-intercept, we choose to do part B first.
B. The graph appears to go through the point (1, 5) and (5, 12), so will have equation
.. y = (12-5)/(5-1)*(x -1) +5
.. y = (7/4)x +3 1/4 . . . . . . . . . . equation of the line
Then for x=13, you have
.. y = (7/4)*13 +3 1/4
.. y = 26
The predicted number of matches won is 26.
A. From part B, the y-intercept is 3 1/4 (looks approximately like that on the graph). It represents the number of matches won if students don't practice at all.
Answer:
$1715
Step-by-step explanation:
You have to find out what 25% of $6,860 is, which is the same as dividing the total by 4, since 1/4 = 25%. So,
$6,860/4=$1715
