Answer: 4 + 8 < 22

Step-by-step explanation:

Take all of the given numbers from the set and add them with 4

4+8=12

4+18=22

4+26=30

Meaning the only answer that is smaller than 22 is 4+8

Four plus eight is less than 22

Find the equation of the line parallel to the line y = 4x – 2 that passes through the point (1, 5).

Lesechka [4]

Answer:

4x-y+1=0

Step-by-step explanation:

here,given equation of a line id

4x-y-2=0.. eqn(i)

equation of any line parallel to line (i) is

4x-y+k=0...eqn(ii)

since, the line(ii) passes through (1,5)[replacing x=1 and y=5 in eqn(ii), we get]

4*1-5+k=0

or, 4-5+k=0

or,-1+k=0

•°•k=1

substituting the value of k=1 in eqn(ii),

4x-y+1=0 is the required equation of the line.

Complete the explanation of the procedure that can be used to solve 5[3(x + 4) − 2(1 − x)] − x − 15 = 14x + 55. Then solve the e

Debora [2.8K]

Answer:

x = 2.

Step-by-step explanation:

5[3(x + 4) − 2(1 − x)] − x − 15 = 14x + 55

5[3x + 12 - 2 + 2x] - x - 15 = 14x + 55

5[5x + 10] - x - 15 = 14x + 55

25x + 50 - x - 15 = 14x + 55 Now we subtract 14x from both sides:

25x + 50 - x - 15 - 14x = 14x - 14x + 55

10x + 50 - 15 = 55 Now we subtract 50, add 15 to both sides:

10x + 50 - 50 - 15 + 15 = 55 - 50 + 15

10x = 20

x = 2.

Graph the relation. Is the relation a function? Why or why not? {(–1, 1), (–2, 1), (–2, 2), (0, 2)} Yes; there is only one domai

Luden [163]

{(–1, 1), (–2, 1), (–2, 2), (0, 2)}

In a function, each input has an output

Each domain has a range. In a function, range can be repeated but domain cannot be repeated. Same domain cannot have two range values.

Here domain is {-1, -2, -2, 0}

Range is { 1, 1, 2, 2}

Domain -2 is repeating so this relation is not a function

Answer : No; a domain value has two range values.

Is y=x^3 a solution of the differential equation yy'=x^5+y

shepuryov [24]

No; we have $y=x^3\implies y'=3x^2$ . Substituting these into the DE gives

$3x^5=x^5+x^3$

which reduces to $x^3=0$ , true only for $x=0$ .
