4/(4+24+22)
4/50
2/25 or (8%)
Answer:
Step-by-step explanation:
y - 3 = (-1/2)(x - 2)
Solve 8x-4y+9=0 for y so as to find the slope of this given line:
8x + 9 = 4y, or y = 2x + 9/4. The slope of the given line is 2. The slope of any line perpendicular to this one is the negative reciprocal of 2, which is -1/2.
Use the point-slope formula: y - k = m(x - h ). (h, k) is (2, 3) and m is -1/2.
Then we have: y - 3 = (-1/2)(x - 2)
Answer:
A, C, F
Step-by-step explanation:
<h3><u>Given</u>:</h3>
A : 4xy- 6x = y + 5
B: y^2-5x = 6
C: y^3 = 6-3x
D: y^2 + 2y =-x
E: |x+y| = 7
F: 5x - 6y + 3 = 0
G: |y| = 2x - 5
H: y^l0-8x- 1
<h3><u>Find</u>:</h3>
Which equations graph as a function of x.
<h3><u>Solution</u>:</h3>
Even-degree polynomial terms in y, and absolute-value expressions involving y can result in a given x-value being mapped to multiple y-values. When that is the case, the relation is not a function.
The relations that are functions of x are ...
A, C, F
__
The others are not, because ...
- even-degree in y: B, D, H
- absolute value in y: E, G
One tenths or simply Zero point one
Rate of change is used to mathematically describe the percentage change in value over a defined period of time. (I looked that up)
So the rate of change is the slope and slope is the ratio of change between any 2 points on a line.
Slope measures the steepness of a line.
Slope is the ratio of the vertical change, called the rise, to the horizontal change called the run between any 2 points on the line.
Slope is written as a fraction in simplest form. 5/10=1/2
Variable for slope: M.
Reply for any more questions, also sorry for a slow response. I thought a lot.
