Each of the line segments in the word MATH are numbered in the graph below. Find the slope (as a ratio of rise over run) of each

Leviafan [203]

Answer:

Line 1: $\infty$

Line 2: $-\frac{4}{3}$

Line 3: $\frac{4}{3}$

Line 4: $\infty$

Line 5: $\frac{7}{4}$

Line 6 : $-\frac{7}{3}$

Line 7: 0

Line 8: 0

Line 9: $\infty$

Line 10: $\infty$

Line 11: 0

Line 12: $\infty$

Step-by-step explanation:

Slope of line is given by the formula:

$\text{Slope = }\dfrac{\text{Change in } y\text{ coordinate}}{\text{Change in } x\text{ coordinate}}$

Line 1:

The change in $x$ coordinate is zero.

Therefore slope of line 1 is $\infty$ .

Line 2:

Change in $y$ coordinate = -4

Change in $x$ coordinate = 3

Slope = $-\frac{4}{3}$

Line 3:

Change in $y$ coordinate = 4

Change in $x$ coordinate = 3

Slope = $\frac{4}{3}$

Line 4:

The change in $x$ coordinate is zero.

Therefore slope of line 4 is $\infty$ .

Line 5:

Change in $y$ coordinate = 7

Change in $x$ coordinate = 3

Slope = $\frac{7}{3}$

Line 6:

Change in $y$ coordinate = -7

Change in $x$ coordinate = 3

Slope = $-\frac{7}{3}$

Line 7:

Change in $y$ coordinate = 0

Slope = 0

Line 8:

Change in $y$ coordinate = 0

Slope = 0

Line 9:

The change in $x$ coordinate is zero.

Therefore slope of line 9 is $\infty$ .

Line 10:

The change in $x$ coordinate is zero.

Therefore slope of line 10 is $\infty$ .

Line 11:

The change in $y$ coordinate is zero.

Therefore slope of line 11 is 0.

Line 12:

The change in $x$ coordinate is zero.

Therefore slope of line 12 is $\infty$ .

Write out the first six multiple of 3 and 5 in separate lists

Sonbull [250]

ANSWER:
________

3: 3,6,9,12,15,18,21,24,27,30

5: 5,10,15,20,25,30,35,40,45,50

The LCM of 3 and 5 is 15

EXPLANTION:
_____________

Looking at the list I made, 15 and 30 is the number that they both have in common, but since it’s asking for the lowest then that would be 15. :)

PUN OF THE DAY:
_______________

If we add, 7xy + 5yz – 3zx, 4yz + 9zx – 4y and –3xz + 5x – 2xy, then the answer is:

vitfil [10]

Answer:

a) 5xy + 9yz + 3zx + 5x - 4y

Step-by-step explanation:

→ (7xy + 5yz - 3zx) + (4yz + 9zx - 4y) + (-3xz + 5x - 2xy)

→ (7xy - 2xy) + (5yz + 4yz) + (-3zx + 9zx - 3xz) + (5x) + (-4y)

→ 5xy + 9yz + 3zx + 5x - 4y

Hence, option (a) is the correct answer.

If 0 < b ≤ 90 and cos(11b + 2) = sin(12b − 4), what is the value of b?

Elza [17]

Answer:

b = 4

Step-by-step explanation:

The given expression is

Cos (11b + 2) = Sin (12b - 4)

Since, Sin(θ) = Cos(90 - θ)

Therefore, Cos (11b + 2) = Cos [90 - (12b - 4)]

Where 0 < b ≤ 90°

11b + 2 = 90 - (12b - 4)

11b + 2 = 94 - 12b

11b + 12b + 2 = 94 - 12b + 12b

11b + 12b + 2 - 2 = 94 - 2

23b = 92

$\frac{23b}{23}=\frac{92}{23}$

b = 4

Therefore, b = 4 will be the answer.
