Answer:
Number line with open circle on 4 and shading to the right.

Explanation:

Call x the number of students that need to sign up so that more than one van is neeed to transport them =>

x + 3 > 7

=> x > 7 - 3

=> x > 4

That is the numbers greater than 4, withount including the number 4.

That in the number line is the set of numbers to the right of 4, and the open circle is used to indicate that the number 4 is not included (a closed circle would indicate that the number 4 is included, which is not the case).

180 - 142 = 38
w = 180 - (38+49)
w = 93

180 - (93 + 42) = 45

y = 180 - 131 = 49

t = 180 - (45 + 49)
t = 86

Write the equation of the graph

adelina 88 [10]

Answer:

x + 2y - 5 = 0

Step-by-step explanation:

We can see that , the graph passes through (0,2.5) and (5,0) . Therefore the ,

x intercept is 5
y intercept is 2.5

We can use the intercept form of equation as ,

=> x/a + y/b = 1

=> x/5 + y/2.5 = 1

=> x + 2y/5 = 1

=> x + 2y = 5

=> x + 2y -5 = 0 .

This equation can be verified by plotting the graph .[ Refer to attachment ]

<h3>Hence the equation of the line is x + 2y - 5 = 0 .</h3>

In △MDK, m=16.4, d=22, and k=19. Identify m∠D rounded to the nearest degree. The figure shows triangle M D K. The length of side

Alex_Xolod [135]

The length of the sides,MD, DK, and KM gives the measure of the angle m<D as c) 76°

<h3>Which method can be used to find the measure of angle m<D?</h3>

In triangle ∆MDK, we have;

m = 16.4

d = 22

k = 19

Using cosine rule, we get;

d² = m² + k² - 2•m•k•cos(D)

Therefore;

2•m•k•cos(D) = m² + k² - d²

$D = arccos \left( \frac{ {m}^{2} + {k}^{2} - {d}^{2} }{2 \cdot m \cdot k} \right)$

Which gives;

$D = arccos \left( \frac{ {16.4}^{2} + {19}^{2} - {22}^{2} }{2 \times 16.4 \times 19} \right) \approx {76}^{ \circ}$

m<D = 76°

The correct option is therefore;

c) 76°
