Answer:
x = 4/9
Step-by-step explanation:
7(6x + 1) = 3(9 - x)
First, distribute the 7 and the 3 across the parentheses.
42x + 7 = 27 - 3x
Now, combine the variables. (Add 3x)
45x + 7 = 27
Now, combine the constants. (Subtract 7)
45x = 20
Now, isolate the x. (Divide by 45)
x = 20/45
Simplify.
x = 4/9
Answer:
B
Step-by-step explanation:
Using Context clues, we can see that the theme is hunting.
Answer: a). 136 degree. b). A kite
Explanation:
360 = POR + OPT + ORT + 44
OPT = ORT = 90 (line TP and TR tangent to the circle)
360 = POR + 90 + 90 + 44
POR = 360 - 224
POR = 136
B). OPTR is a kite because OP = OR and TP = TR
Definition of a kite:
A quadrilateral whose 4 sides can be grouped into two pairs of equal sides that are adjacent to each other.
Answer:
3/1 is the slope.
Step-by-step explanation:
Slope formula: y2 - y1/x2 - 1
Plugging in the given values, we get:
-9 - (-6)/3-4
-3/-1
Two negatives cancel each other out, so:
3/1 is the slope.
Answer:
The answer to your question is: B = parallel lines
Step-by-step explanation:
Data
4x - 2y = - 5 (I)
16x - 8y = -2 (II)
Find the slopes of both lines
(I) 4x - 2y = -5
- 2y = - 4x - 5
y = -4/-2 x - 5/-2
y = 2x + 5/2 slope = 2
(II) 16x - 8y = -2
- 8y = -16x - 2
y = -16/-8 x - 2/-8
y = 2x + 1/4 slope = 2
As the slopes are the same, they are parallel lines.
