2. The line segment graphed on the coordinate plane represents a roof with several triangular supports. Each support is triangular, with a horizontal board that starts on the edge of the roof and connects with a vertical board that ends on the edge of the roof as shown.
(a) Does each support have the same starting coordinates? Explain.
(b) Does each support have the same ending coordinates? Explain.
(c) Does each support have the same change in x-values? Explain.
(d) Does each support have the same change in y-values? Explain.
(e) Does each support have the same ratio of change in y-values over change in x-values? Explain.
Answer:
Answers
a) No, the first support starts at (0,0) and the 2nd one starts at (2,1)
b) No, first one ends at (2,1) 2nd one ends at (6,3)
c) No, 2 ( 0 to 2) does not equal 4 ( 2 to 6)
d) No, 1 ( 0 to 1) does not equal 2 (1 to 3)
e) Yes, this is the slope of the diagonal line: 1/2
Answer:
(a) No
(b) No
(c) No
(d) No
(e) Yes
Step-by-step explanation:
(a) No, they don’t. The starting position for the small triangle is (0,0). The starting position for the large triangle is (2,1).
(b) No, they don’t. The ending position for the small triangle is (2,1). The ending position for the large triangle is (6,3).
(c) No, they don't. 2 - 0 doesn't equal 6 - 2.
(d) No, they don't. 1 - 0 does not equal 3 - 1
(e) Yes, they do. 3-1/6-2 = 2/4 = 1/2

5n-12=3n+4 equals what
Answers
2n-12=4
2n=16
n=8
5n-12+12 = 3n+4+12
= 5n = 3n+16
Then take away 3n from both sides:
5n-3n = 3n+16-3n
= 2n = 16
Then divide both sides by 2
2n/2 = 16/2
= n = 8

5/36
2:9
3 to 18
1:3
Answers
You find the ratio by dividing two numbers.
Answer: The largest ratio is (d) 1 : 3.
Step-by-step explanation: We are given to select the larges ratio among the given options.
The first ratio is
[tex]\dfrac{5}{36}.[/tex]
The second ratio is
[tex]2:9=\dfrac{2}{9}=\dfrac{2\times 4}{9\times 4}=\dfrac{8}{36}.[/tex]
The third ratio is
[tex]3\textup{ to }18=\dfrac{3}{18}=\dfrac{3\times 2}{18\times 2}=\dfrac{6}{36}.[/tex]
The fourth ratio is
[tex]1:3=\dfrac{1}{3}=\dfrac{1\times 12}{3\times 12}=\dfrac{12}{36}.[/tex]
Arranging all the ratios in ascending order, we have
[tex]\dfrac{5}{36},~\dfrac{6}{36},~\dfrac{8}{36},~\dfrac{12}{36}\\\\\\\Rightarrow \dfrac{5}{36},~\dfrac{3}{18},~\dfrac{2}{9},~\dfrac{1}{3}.[/tex]
Thus, the largest ratio is (d) 1 : 3.
how to do 8c+6j=5p solve for c and plz show how you got it
Answers
We're simply just trying to get c onto it's own side, so we must get everything onto the other side of c.
So, subtract 6j from both side.s
8c = 5p - 6j
Then, divide both sides by 8.
8c ÷ 8 = (5p - 6j) ÷ 8
Simplify.
c = 5p/8 - 6/8j
Simplify.
c = 5/8p - 3/4j → [tex]c = \frac{5}{8} p - \frac{3}{4} j[/tex]

We have the equation,

We simplify the constant terms to obtain,

We now group the constant terms on one side of the equation and the variable terms on the other side.
[tex]11n - 3n = - 24[/tex]
We simplify to obtain,
[tex]8n = - 24[/tex]
We divide both sides of the equation to get,

What is m∠D ?
Answers
-3x + 58 = x - 2
-3x - x = -2 - 58
-4x = - 60
x = -60/-4
x = 15
m < D = x - 2....15 - 2 = 13 <====
m < C = -3x + 58....-3(15) + 58 = 13
Answer:
m<D is [tex]13^{0}[/tex]
Step-by-step explanation:
Vertically opposite angles are said to be equal angles, thus;
m<C = m<D
So that,
-3x + 58 = x -2
-3x - x = -2 -58
- 4x = - 60
x = [tex]\frac{- 60}{- 4}[/tex]
x = 15
Thus,
m< D = x - 2
= 15 - 2
= [tex]13^{0}[/tex]
Therefore, m<D is [tex]13^{0}[/tex]
