Which are composite numbers? Select all that are true. 49 35 32 41 47

1 answer:

7 0

A prime number is a number whose factors are 1 and itself
Eg 7
7 is a prime number because it only comes in table one and 7
Or it’s only factors are 1 and itself
A composite number comes in 1, itself and other tables
Eg. 16
It comes in table 1, 2, 4 and 16

1.Graph the equation y = 6x -18:

RSB [31]

Answer:

1. Given the equation: y =6x-18 ......[1]

The intercepts of a line are the points where the line intercepts or crosses the horizontal and vertical axes.

(A)

Horizontal intercept(x) states that the point where the line crosses the x-axis and at this point y=0

Put y=0 in equation [1]

$0=6x-18$ or

$6x=18$

Ordered pair of horizontal intercept(x) = (3,0)

(B)

Vertical intercept(y) states that the point where the line crosses the y-axis and at this point x=0.

Put x=0 in equation [1]

$y=6\cdot 0-18$ or

$y=-18$

Ordered pair of vertical intercept(y) = (0,-18)

You can also see the graph of the function y =6x-18 as shown in Figure-1.

Graph the equation y+2x =4

to find the horizontal intercept and vertical intercept we follow the same process as done in 1

(A)

Horizontal intercept (x) = 2

Ordered pair = (2,0)

(B)

Vertical intercept (y) = 4

Ordered pair = (0,4)

Also, you can see these in the graph as shown in the Figure-2

Given: The slope(m) of a line is $\frac{3}{4}$

Two lines are parallel if their slopes are equal and they have different y - intercepts.

(A).

The slope of a line parallel to it is, $\frac{3}{4}$

(B)

The slope of the original line is $\frac{3}{4}$ .

A line perpendicular to another line has a slope that is the negative reciprocal of the slope of the other line.

Therefore, slope of a line perpendicular to it is; $-\frac{1}{m} = -\frac{4}{3}$

The graph of the equation y =4x+5 as shown in figure 3

The x-intercept of this line is $\frac{-5}{4}$ = -1.25

And the y-intercept of this line is y =5.

Graph of the equation y = -3 represents the line as shown in figure 4.

Solve the equation:

6y-18x = -18

6y = 18x-18

Divide by 6 to both sides of an equation ; we get

y = 3x-3 or

y = 3(x-1)

Given the equation Y -3 equals 1/2 (X +6 )in point slope form identify the equation of the same line in standard form

liberstina [14]

The standard form of a line:

$Ax+By=C$

We have the equation of a line in the slope-point form:

$y-3=\dfrac{1}{2}(x+6)$ use distributive property

$y-3=\dfrac{1}{2}x+3$ add 3 to both sides

$y=\dfrac{1}{2}x+6$ multiply both sides by 2

$2y=x+12$ subtract x from both sides

$-x+2y=12$ change the signs

$x-2y=-12$

The number of people that belong to a certain social website is 412 and growing at a rate of 5% every month. How many members wi

vladimir1956 [14]

Population are always modeled by exponential growth equation given by:
f(x)=a(1+b)^t
where:
a=original number
b=rate of growth
t=time
thus
f(x)=412(1.05)^t
the population after 9 months will be:
f(9)=412(1.05)^9=639.15=639
