kykrilka [37]

Numbers whose only factors are 1 and itself is known as prime numbers , numbers whose factors besides 1 and itself are composite numbers, we can use the sieve of Eratosthenes to determine whether the number is prime or composite.

Given a paragraph in which there are blanks:

A _____ is a number whose only factors are 1 and itself. If a number has factors besides 1 and itself, it is called a _____. You can use divisibility rules or _______ to help you determine whether a number is prime or composite.

We are required to fill the blank with appropriate options.

We have to fill "prime numbers" in the first blank.

We have to fill "composite numbers" in the second blank.

We have to fill "the sieve of Eratosthenes" in the third blank.

Hence numbers whose only factors are 1 and itself is known as prime numbers , numbers whose factors besides 1 and itself are composite numbers, we can use the sieve of Eratosthenes to determine whether the number is prime or composite.

Need help with problems 16 and 17, please? I'll do brainiac

Answer: 16) y=-0.5x+3 and 17) y=2x-3

Step-by-step explanation:

16: The slope-intercept form of a line is y=mx+b, where m is the slope, and b is the y-value at the y-intercept.

Since y=3 at x=0, the y-intercept is (0,3), and b=3.

Slope= $\frac{y_{2} -y_{1} }{x_{2}-x_{1} }$ where ( $x_{1} ,y_{1}$ ) and ( $x_{2} ,y_{2}$ ) are two points on the line. Choose (0,3) and (2,2):

Slope= $\frac{2-3}{2-0}$ =-0.5

Plug m=-0.5 and b=3 into y=mx+b:

y=-0.5x+3

17: The slope-intercept form of a line is y=mx+b, where m is the slope, and b is the y-value at the y-intercept.

Because y=-3 at x=0, the y-intercept is (0,-3), and b=-3.

Slope= $\frac{y_{2} -y_{1} }{x_{2}-x_{1} }$ where ( $x_{1} ,y_{1}$ ) and ( $x_{2} ,y_{2}$ ) are two points on the line. Choose (0,-3) and (1,-1):

Slope= $\frac{-3-(-1)}{0-1}$ = $\frac{-2}{-1}$ =2

Plug m=2 and b=-3 into y=mx+b:

y=2x-3

3c=2(c-1) in a verbal expression

kifflom [539]

9514 1404 393

Answer:

"three times a number is the same as twice the difference of the number and 1"

Step-by-step explanation:

3c is "three times a number"

2(c -1) is "two times the difference of the number and 1"

When writing the description of the right-hand side, one needs to be careful to write it so there is no ambiguity with respect to what is being multiplied by 2. For example, if you say, "two times one less than the number", it is not clear whether that is c -2×1 or 2×(c -1).

A suitable description is ...

three times a number is the same as twice the difference of the number and 1

Eddie the elf made 13 toys one day in the workshop. some were dolls and the rest were action figures. the number of action figur

Lunna [17]

To solve this problem we first call x = number of action figures, y = number of dolles. A system of two equations with two unknowns must be made to describe the problem. The system is the following:
(x + 1) + y = 13
1/2 * x = y.
Then solving the system we have that x = 8 and y = 4.
Since we know that the number of action figures is twice as many dolls plus one, then x = 8 + 1 = 9.
Thus,
dollos = 4
action figures = 9
