What is the number?
OA. 12
OB. 4
OC. 16
OD. 48

Answers

Answer:

it's either A (12) or B(4) but I think it's 12

Step-by-step explanation:

if we make it into an equation, we get

8(x-6)=4x

8x-48=4x

-48=-4x

-12=-x

x=12

the reason why it might be 4 as well is if we switch the order

8(6-x)=4x

48-8x=4x

48=12x

x=4

So both of those could be correct, but I'm thinking that because they said between a number and 6, then x goes first, so therefore, I think it is 12

A. Determine if there is a proportional relationship between cinnamon rolls and the cost of cinnamon rolls. If there is determine the unit rate.

Answers

Answer:

it is $2.50 multiplied by 4

Step-by-step explanation:

“ Create two whole number division problems that have a quotient of 9 and a remainder of 5. Justify which is greater using decimal division”

Answers

Answer and equation: If we choose two whole numbers; 8 and 10

We want to divide certain numbers by 8 and 10 to get 9 remainder 5.

In this case; 77 divided by 8 is equal to 9 rem 5

and 95 divided by 10 is equal to 9 rem 5

To justify which is greater, we use decimal division;

= 77 divided by 8 we get 9.625 ( 77 ÷ 8 = 9.625)

and

= 95 divided by 10 is equal to 9.5 (95 ÷10 = 9.5)

Therefore; the first case is greater since 9.625 is greater than 9.5

That is; 9 rem 5 got after dividing 77 by 8 is greater than 9 rem 5 got after dividing 95 by 10.

then, i moved the terms.

-2g > 15.8 - 19

the, i calculated that.

-2g > -3.2

finally, i divided both sides.

Answers

Answer:

the correct answer is a

The correlation between the ages of husbands and wives if men always married woman who were :

(a) 3 years younger than themselves

Correlation occurs as two variables or factors are related, and therefore the change in one variable affects another. In the situation presented there are 2 variables:  According to our constitution,  the legal age of men is 21 years and 18 years for women is 18 years.So according to the question the correlation between the ages of husbands and wives if men always married woman who will always be 3 years younger than themselves.

A quadratic function y = f(x) is plotted on a graph and the vertex of the resulting
parabola is (6, -3). What is the vertex of the function defined as
g(x) = f(-x) - 3?

Answers

Answer: (-6, - 6)

Step-by-step explanation:

Here we have two transformations, and the first step will be to explain those transformations:

Reflection over the y-axis.

For a function f(x), the reflection over the y-axis is written as:

g(x) = f(-x)

Then if we initially had a point (x, y), the transformed point will be (-x, y).

Vertical translation.

We can define a vertical translation of N units as:

g(x) = f(x) + N

if N > 0, the translation is up.

If N < 0, the translation is down.

Then if we start with a point (x, y), the transformed point will be (x, y + N)

In the case of this problem we have g(x) = f(-x) - 3

This means that N = -3

Then if we initially had the vertex at the point (6, - 3)

The transformed point will be: changing the sign of the x-component and subtracting 3 in the y-component, then the transformed vertex point is:

(-6, -3 - 3) = (-6, - 6)

The vertex of the resulting  parabola will be (-6, -6)

Rule of reflection

Given the function y= f(x), plotted on a graph and the vertex of the resulting

parabola is (6, -3), if this coordinate is reflected over the y-axis, the reflection rule will be:

[tex](x,y) \rightarrow (-x, y)[/tex]The coordinate (6, -3) under this translation will give (-6, -3)

To get the corresponding function [tex]g(x) = f(x) - 3\\[/tex]

[tex]g(x) = [(-6, -3) - 3]\\g(x) = (-6, -3-3)\\g(x) =(-6, -6)[/tex]

Hence the vertex of the resulting  parabola will be (-6, -6)

Answers

Answer:

Step-by-step explanation:

7[tex]y^{2}[/tex]+[tex]x^{2}[/tex]=64x+y=4

First, we isolate the variable on the second equation so that we can have an x solution to plug in:

x=-y+4

Now, we plug this in to the first equation:

[tex]7(-y+4)^{2} +(-y+4)^{2} =64[/tex]

We can now put the 7 into the parentheses and then square root the equation:

[tex]\sqrt{(-7y+28)^{2}} +\sqrt{(-y+4)^{2}} =\sqrt{64}\\-7y+28-y+4=8\\-8y=40\\y=-40[/tex]

We then plug this in to the original equation to find x

[tex]x+-40=4\\x=-36[/tex]

This means y=-40 and x=-36. I believe that's what you were asking. Let me know if it is something else
