Answer:

[tex]y= 2x + 4[/tex]

Step-by-step explanation:

We are given an equation of [tex]2x-y+3 =-1[/tex] and we need to put into [tex]y = mx+b[/tex] form.

First, we subtract 3 on both sides to get the variables all on one side.

[tex]2x-y+(3 - 3)=(-1 -3)\\\\[/tex]

[tex]2x-y = -4[/tex]

We need to now isolate y on its own so we subtract [tex]2x[/tex] on both sides.

[tex](2x-2x)-y=(-4-2x)[/tex]

[tex]-y=-2x-4[/tex]

We almost done! We then need to divide the invisible negative on both sides which is a -1.

[tex]\frac{-y}{-1}=\frac{-2x-4}{-1}[/tex]

[tex]y=2x+4[/tex]

When we divide the the negatives together, we know that two negatives divided together is a positive. Therefore, we get our answer [tex]y=2x+4[/tex]

Answer:

[tex]-2t^2+ 6t -1 > 0[/tex]

Step-by-step explanation:

Function Modeling

The height h in feet of the stick threw by Tim is modeled by the function:

[tex]h = -16t^2+ 48t[/tex]

where t is the time in seconds.

It's required to write an inequality that can be used to find the interval of time in which the stick reaches a height of more than 8 feet, i.e. h > 8.

Using the given model, we write the inequality:

[tex]-16t^2+ 48t > 8[/tex]

Dividing by 8

[tex]-2t^2+ 6t > 1[/tex]

Subtracting 1, we get the required inequality:

[tex]\mathbf{-2t^2+ 6t -1 > 0}[/tex]

Answer:

you want more than 8 feet so the answer would be -16t^2+48t>8

Step-by-step explanation:

h=-16t^2+48t

-16t62+48t>8

-16t^2+48t=8

divide both sides of the equal sighn by 8

-2t^2+6t=1

put the symbol back in

-2t^2+6t>1

substitute a random mumber for t

-2(5)^2+6(5)>1

-10^2+30>1

subtract 30 from both sides

100>-29

state is true so -16t62+48t>8 is the correct answer

Answer:

D

Step-by-step explanation:

choice A is not guaranteed since the values varied from 0 to 7.

choice B seems alright, but doesn't include about or anything about the long run.

choice C is incorrect because 50% are less than 3.12 and 50% are greater than 3.12.

choice D seems pretty good, since it says average, long run, approach, etc.

choice E is incorrect because it says "will be". It is not definite.

Option B is correct.

According to the question,

The values varied from 0 to 7, and distribution of relative frequencies for the values was created.

Let the random variable X represent the number of days per week that a member visits. The mean of X is 3.12.

Interpretation A is not the best interpretation as according to questions the values varied from 0 to 7.

Interpretation B, According to data given B's following the condition, but doesn't include about anything about the long run.

Interpretation C, According to the data given C is not the best interpretation because 50% are less than 3.12 and 50% are greater than 3.12.

Interpretation D, According to the data given D is not the best interpretation, since it says average, long run, approach, etc.

Interpretation E, According to the data given E is incorrect because it says "will be" but It is not definite.

Hence, out of the given options, option B is the correct one.

Answer:

1 solution

Step-by-step explanation:

You can solve these equations by using substitution. y = 3x+4, so 3y-6x=2 can also be written as 3(3x+4)-6x = 2 if you plug in the y value in the second equation. Then, simplify and you will get your x answer. If you plug that into the first equation, you will get your y answer.

Answer:

The coordinates of P are (1,3.5)

Step-by-step explanation:

Here, we simply want to find the coordinates of point P that divides line AB in the ratio 1 to 3

Mathematically, that would be;

(x,y) = (nx1 + mx2)/(m + n) , (ny1 + my2)/(m + n)

where in this case m = 1, n = 3

(x1,y1) = (-1,2)

(x2,y2) = (7,8)

Thus, we have ;

(x,y) = (3(-1) + 1(7)/)1+3) , (3)2) + 1(8)/(1 + 3)

(x,y) = (-3+7)/4 , (6 + 8)/4

(x,y) = 4/4, 14/4

(x,y) = (1,3.5)

Answer:

The answer is A.

Step-by-step explanation:

Because after math is that the 79$ one goes down to 63.2 and the 85$ one goes down to 63.75. So the best deal would be A.

Step-by-step explanation:

Answer:

The equation of the line that passes through the point (3,-3) and has a slope of 0 will be:

[tex]0=y+3[/tex]

Step-by-step explanation:

The point-slope form of the equation of a line is:

[tex]\:y\:-\:y_1\:=\:m\left(x-x_1\right)[/tex]

where

As the slope is [tex]m=0[/tex], and the point is [tex](3,-3)[/tex]

so

Equation of the line will be:

[tex]\:y\:-\:y_1\:=\:m\left(x-x_1\right)[/tex]

[tex]y\:-\:\left(-3\right)\:=\:0\left(x-3\right)[/tex]

Further simplifying

[tex]0=y-\left(-3\right)[/tex]

[tex]0=y+3[/tex]

Therefore, the equation of the line that passes through the point (3,-3) and has a slope of 0 will be:

[tex]0=y+3[/tex]

Let g(n) = y

We then have y = -n + 3.

Exchange y and n.

n = -y + 3

Solve for y.

n - 3 = -y

(n - 3)/(-1) = -y/(-1)

-(n - 3) = y

Replace y with g^(-1) n.

-(n - 3) = g^(-1) n
