change 3/4 to 6/8 and add 6/8 and 1/8 to get 7/8
he walked 7/8 miles in total :)
Answer:
(1/2, 0)
Step-by-step explanation:
To find the y-intercept, set x = 0 and find y: y = 4(0) - 2 = -2, so that we have the point (0, -2).
To find the x-intercept, set y = 0 and find x: 0 = 4x - 2, or x = 1/2, so that we have the point (1/2, 0). This corresponds to the first answer choice.
The range of the <em>quadratic</em> function y = (2 / 3) · x² - 6 is {- 6, 0, 18, 48}.
<h3>What is the range of a quadratic equation?</h3>
In this case we have a <em>quadratic</em> equation whose domain is stated. The domain of a function is the set of x-values associated to only an element of the range of the function, that is, the set of y-values of the function. We proceed to evaluate the function at each element of the domain and check if the results are in the choices available.
x = - 9
y = (2 / 3) · (- 9)² - 6
y = 48
x = - 6
y = (2 / 3) · (- 6)² - 6
y = 18
x = - 3
y = (2 / 3) · (- 3)² - 6
y = 0
x = 0
y = (2 / 3) · 0² - 6
y = - 6
x = 3
y = (2 / 3) · 3² - 6
y = 0
x = 6
y = (2 / 3) · 6² - 6
y = 18
x = 9
y = (2 / 3) · 9² - 6
y = 48
The range of the <em>quadratic</em> function y = (2 / 3) · x² - 6 is {- 6, 0, 18, 48}.

Answer:
Perimeter = 31.4in
Area = 78.5in^2
Step-by-step explanation:
Perimeter -
2 x 5 x 3.14 = 10 x 3.14 = 31.4in
Area -
5 x 5 x 3.14 = 25 x 3.14 = 78.5in^2
The quickest way for converting small numbers like this to binary would probably be to find the closest power of 2, then add/subtract intermediate powers of 2 as needed.
Converting 8 is immediate, since it's already a power of 2:
Converting 15 and 17 is also pretty easy if you're familiar with the rules of arithmetic in binary.
