Triss [41]

Answer:

Step-by-step explanation:

(fg)(x) )

(x+4)*(3x^{2} -7)=3x^{3} -7x+12x^{2} -28 = 3x^{3} +12x^{2} -7x-28

Why is (0,5) not a solution to the equation 5x + y=10? Explain
lina2011 [118]

Answer:

see below

Step-by-step explanation:

5x + y=10

Let x = 0 and y = 5

5*0 +5 = 10

0+5 = 10

5 =10

This is not true so (0,5) is not a solution

Arrange the pairs of points in increasing order of slopes of the lines joining them
sladkih [1.3K]

Answer:

(27,2) and (243,18)

(63,9) and (84,12)

(45,15) and (60,20)

(27,12) and (72,32)

(15,30) and (20,40)

(12,32) and (18,48)

(18,63) and (24,84)

Step-by-step explanation:

Formula for slope of a line is

m=\dfrac{y_2-y_1}{x_2-x_1}

a) (15,30) and (20,40).

m_a=\dfrac{40-30}{20-15}=\dfrac{10}{5}=2

Similarly find the slope of other lines.

b) (12,32) and (18,48).

m_b=\dfrac{48-32}{18-12}=\dfrac{16}{6}=2.67

c) (27,12) and (72,32).

m_c=\dfrac{32-12}{72-27}=\dfrac{20}{45}=0.44

d) (45,15) and (60,20).

m_d=\dfrac{20-15}{60-45}=\dfrac{5}{15}=0.33

e) (27,2) and (243,18).

m_e=\dfrac{18-2}{243-27}=\dfrac{16}{216}=0.074

f) (18,63) and (24,84).

m_f=\dfrac{84-63}{24-18}=\dfrac{21}{6}=3.5

g) (63,9) and (84,12).

m_g=\dfrac{12-9}{84-63}=\dfrac{3}{21}=0.143

After arranging the slopes in increasing order, we get

m_e

So, required arrangement of ordered pairs is

(27,2) and (243,18)

(63,9) and (84,12)

(45,15) and (60,20)

(27,12) and (72,32)

(15,30) and (20,40)

(12,32) and (18,48)

(18,63) and (24,84)
