Can someone teach me how to do this pleasseeee!

Answers

so the equation is 5-x3
x^3=x*x*x
so you have x=-2
That means y=5-(-2*-2*-2)
y=5-(-8) which gives y=13
Do this for every x and get the y

Answer:

y's go

13, 6, 5, 4, -3

Step-by-step explanation:

well so you have the equation y = 5 - x^3

you are given the x for all of them

y = 5 - (-2)^3

5 - (-8) = 13

y = 5 - 0^3

5 - 0 = 5

y = 5 - 1^3

5 - 1 = 4

y = 5 - 2^3

5 - 8 = -3

How can the product of 5 and 0.3 be determined using this number line? Number line from 0 to 2.0 with tick marks at every tenth. An arrow goes from 0 to 0.3. Enter your answers in the boxes. Make_____ jumps that are each_____unit long. You end at______ , which is the product of 5 and 0.3.

Answers

Answer:

5      0.3     1.5

Step-by-step explanation:

you count by 3

To determine the product of 5 and 0.3 using the number line described, make 5 jumps that are each 0.3 units long, you end up at 1.5.

Since the distance between each consecutive tick marks is 0.3 ; we only need to jump 5 times starting from the 0 towards the right.

Hence, jumping five times towards the right by a distance of 0.3 each time gives a value of 1.5 on the final or end point which is also the product of 0.3 × 5

If 2(6 + 3x) + 1 = - 5 + 3(x - 1), what is the value of x?

Answers

Answer: x = -7

Step-by-step explanation:

2(6 + 3x) + 1 = - 5 + 3(x - 1)

(2) (6) + (2) (3x) + 1 = -5 + (3) (x) + (3) (-1)

12 + 6x + 1 = - 5 + 3x + - 1

( 6x ) + ( 12 - 1 ) = ( 3x ) + ( -5 + -3 )

6x + 13 = 3x - 8

6x + 13 - 3x = 3x - 8 - 3x

3x + 13 = -8

3x + 13 - 13 = -8 - 13

3x = -21

3x/3 -21/3

X = -7

12+6x+1= -5+3x-3
3x= -21
x= -7

Step-by-step explanation:

This is because the ratio of black to white can be set up as 1/4, for every one black bead there is 4 white so what is 1/4x that equals 4? simple, x=16 because 16/4 equals to 4 so it would be 4 black beads to 1 white bead.

thirty percent of all seventh graders own a bracelet. explain whether the sample closely estimates the percentage of seventh graders who own a bracelet.

30 seventh graders, 3 own a bracelet

Answers

it doesn’t. if there were 30 7th graders and 30% owned a bracelet that would mean 9 own a bracelet.

The sample of 3 seventh graders who own a bracelet out of 30 seventh graders does not closely estimate the thirty percent of all seventh graders owning bracelets.

What is a percentage?

Percentages are fractions where the denominator is 100.

We have,

Number of seven grade students = 30

Number of students who own a bracelet = 3

The percentage of seven grade student who owns a bracelet:

= (3 / 30) x 100

= (1/10) x 100

= 10 %

This means that 10% of seven grade student owns a bracelet.

Thus, the sample does not closely estimate the percentage of seventh graders who owns bracelets.
