Answer:
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 
x + 3 ← is in slope- intercept form
with slope m = -
Given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
=

Answer:
2. the figure has rotatinal symetry
Step-by-step explanation:
Step-by-step explanation:
7 1/5 × 49 7/5 = 49
convert mixed numbers into improper fractions (whole number × denominator + numerator)
7 × 5 + 1 = 36
49 × 5 + 7 = 252
36/5 × 252/5 = 49
All fractions must have a common denominator
49 × 5 = 245
36/5 × 252/5 = 245/5
Add numerators
36 + 252 = 288
288/5 = 245/5
57 3/5 = 49
These do not equal each other according to my calculations. Is the problem written correctly? Or did I misinterpret a given number?
Using the midpoint concept, it is found that the value of a is of a = 2.
<h3>What are the coordinates of the points?</h3>
Researching this problem on a search engine, the coordinates are given as follows:
<h3>What is the midpoint concept?</h3>
The midpoint between two points is the halfway point between them, and is found using the mean of the coordinates.
Hence the following system of equations can be built:
(b + 1 + 2a)/2 = 3.
b + 1 + 2a = 6.
b = 5 - 2a.
(a + 2 + 3b + 3)/2 = 5
a + 3b + 5 = 10
a + 3b = 5.
Since b = 5 - 2a, we have that:
a + 15 - 6a = 5.
5a = 10
a = 10/5
a = 2.
The value of a is of a = 2.
