Answer:
Explanation:
The given points are:
- (0, 275)
- (1, 220)
- (2, 165)
- (3, 110)
- (4,55)
- (5, 0)
Since a <em>straight line joins</em> all the points, the equation that models the <em>relationship</em> is linear and you can find the slope-intercept equation which has the general form:
Where:
is the slope
is the y-intercept
<u>1. Find the slope</u>
You can use any two ordered pairs.
- m = rise/run = Δy/Δx = [220 - 275] /[1 - 0] = - 55
<u>2. Find the y-intercept</u>
The y-intercept is the value of y when x = 0; thus it is 275.
<u>3. Substitute in the slope-intercept equation</u>
That is the last option.
Answer:
153 degrees
Step-by-step explanation:
15+12=27
180-27=153
4x+(3x-8)=90
4x+3x-8=90
7x=98
x=98/7
x=14
If x=14,
angle CDJ is:
(3(14)-8) degrees
=34 degrees

<h3>
Answer: C) integers and rational numbers</h3>
Explanation:
The set of integers is {..., -3, -2, -1, 0, 1, 2, 3, ...} basically any number that does not have a decimal or fractional part to it. We can say that this set is composed of positive and negative whole numbers along with 0. So this is why -3 is in the set of integers.
The value -3 is not in the set of whole numbers because the set of whole numbers is {0, 1, 2, 3, 4, 5, 6, ...}, so this rules out choice D.
Choice B is also eliminated because -3 is a rational number. We can write -3 as a fraction of two integers, example: -3 = -3/1. Any rational number is not irrational, and vice versa.
Choice A is ruled out because it's not the most complete answer (though its technically true).
