Answer:

on week 8 he will weight 208 lbs

Step-by-step explanation:

i dont know I guessed and got it right

John weigh 217.7 lbs at the end of 8 week.

An estimate of the line that depicts the actual, but unidentified, linear relationship between the two variables is called a regression line. When the value of the explanatory variable is known, the regression line's equation is used to predict (or estimate) the value of the response variable.

Given:

Using the regression model

In II nd week the calories is 2950 and weight 250.

and, Vth week the calories is 7400 and weight 216.

let Exercise be x and the weight is y then

= (216 - 250)/ (7400- 2950)

= -9/ 4450

So, at the start of week john weight

y= -9/ 4500 x + 230

Now, At the end of 8 week John weighs

= -9/4500 (6100) + 230

= 217.7

Answer: y=7x-68

Step-by-step explanation: Ok so you would use point slope to slope so plug the points in.  y+30=7(x-4)  then if you need to convert it further into slope intercept form just simplify and distribute. So y+30=7x-28, subract 30 from both sides to get y=7x-68

Hence, the slope of line is [tex]y=7x-58[/tex].

What is the slope of line?

The slope of a line gives the measure of its steepness and direction. The slope of a straight line between two points says [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] can be easily determined by finding the difference between the coordinates of the points.

The slope is usually represented by the letter ‘m’.

Here given that,

Slope is [tex]7[/tex] and the coordinates of [tex](x,y)=(4,-30)[/tex].

As we know slope of line is

[tex]y=mx+c[/tex]

where [tex]m[/tex] is the slope.

So,

[tex]y+30=7(x-4)[/tex]

Now convert it further into slope intercept form

[tex]y+30=7x-28\\\\y=7x-28-30\\\\y=7x-58[/tex]

Hence, the slope of line is [tex]y=7x-58[/tex].

Answer:

The perimeter is 60 inches in total, and 15 for each side.

Step-by-step explanation:

The perimeter of a square is four times the length of one of its sides.  So you divide 5 by 4 to get the length of each individual side.

5feet /4 sides = 1.25 feet

So each side is 15 inches long.

Answer:

52°

Step-by-step explanation:

Let the measure of the third angle be x°.

Since, straight line is broken into three angles. So, the sum of all the three angles will be equal to 180°.

38° + 90° + x = 180°

128° + x = 180°

x = 180° - 128°

x = 52°

Answer:

52°

Step-by-step explanation:

So, we basically know that,

A straight Angle=180°

When it has been broken into 3 pieces, we have gotten one which is 38°and a right angle.

Now , we know that

A right angle= 90°

So, we need to do,

Sum of known angles= 38+90=128°

Lastly,

Unknown angle = 180° - 128° = 52°

Answer:

All of the above.

Step-by-step explanation:

By looking at the graph and taking point x at 4 and y at around 300. This shows us the precise rate of the graph which is when x = 4, y is equal to 300.

Now if we substitute the x as 4 in any of the equations we will get values larger than 300. Therefore, all the equations have a greater rate of change.

y = 85(4) = 340 (Greater)

y = 50(4) + 150 = 350 (Greater)

y = 65(4) + 100 = 360 (Greater)

Answer:

Missing context,

Do you have a ratio I could work with?

Answer:

What you need to do is multiply 12 by 2 and then multiply 100 by 2 and then you add them which equals 240

12x2 = 24, 100x2 = 200

Kitten is 15 seconds and dog is 10 seconds

In work and time the time taken is inversely proportional to the work done. Work and time is a concept to solve the problems of work related question in a given time.The kitten eats a sausage in 15 seconds  and puppy eats a sausage in 10 seconds.

In work and time the time taken is inversely proportional to the work done. Work and time is a concept to solve the problems of work related question in a given time

Puppy and kitten eats one sausage combined in 6 sec.

A puppy eats a sausage 5 seconds faster than a kitten eats an identical sausage.

Let puppy eats a sausage in [tex]x[/tex] seconds and kitten eats a sausage in [tex]y[/tex] seconds.

As Puppy and kitten eats one sausage combined in 6 sec.Thus,

[tex]\dfrac{1}{x} +\dfrac{1}{y} =\dfrac{1}{6}[/tex]

Let above equation is equation one.

A puppy eats a sausage 5 seconds faster than a kitten eats an identical sausage. Thus

[tex]\dfrac{1}{x} -\dfrac{1}{y}=\dfrac{1}{5}[/tex]

Put this value of [tex]x[/tex] in the  the equation one to get the value of y. Therefore,

[tex]\dfrac{1}{6} -\dfrac{1}{y}-\dfrac{1}{y}=\dfrac{1}{5}[/tex]

[tex]-\dfrac{1}{2y}=\dfrac{1}{5}-\dfrac{1}{6}[/tex]

[tex]-\dfrac{1}{2y}=-\dfrac{1}{30}[/tex]

[tex]y=15[/tex]

Thus the kitten eats a sausage in 15 seconds.

Put the value of y in equation one. thus,

[tex]\dfrac{1}{x} +\dfrac{1}{15} =\dfrac{1}{6}[/tex]

[tex]\dfrac{1}{x} =\dfrac{1}{6}-\dfrac{1}{15}[/tex]

[tex]\dfrac{1}{x} =\dfrac{9}{90}[/tex]

[tex]x=10[/tex]

Thus the puppy eats a sausage in 10 seconds.

Hence the kitten eats a sausage in 15 seconds  and  puppy eats a sausage in 10 seconds.

Answer:

45

Step-by-step explanation:

18+27=9(2+3)=9(5)=45

The sum of the numbers 18 and 27 will be 45.

The largest factor of the two numbers which divides both the numbers is called as greatest common factor or GCF. The greatest common multiple is the common number multiplied by both numbers.

The distributive property of binary operations in mathematics generalizes the distributive law, which states that in elementary algebra, equality is always true.

Given sum is 18 + 27. The greatest common multiple between the two numbers is 9 take it common and then solve.

E = 18+27

E =9(2+3)

E =9(5)=45

Therefore, the sum of the numbers 18 and 27 will be 45.

Step-by-step explanation:

In order to do f(g(4)), we need to find what g(4) is in order to input it into the function f(x).

g(4) = 2(4) = 8

f(8) = 3(8^2) - 3(8) + 6 = 174

Step-by-step explanation:

- Subtracting the equation will get rid of y variable therefore it's a correct and logical first step to solve the system

- The solution is indeed (-3, -3) as if we substitute these values in both equation, the equation will be correct and valid.

[tex]-2(-3)+(-3)=3[/tex] (Correct)

[tex]3(-3)+2(-3)=-15[/tex] (Correct)

- We have already determined the logical first step. Multiply by -2 will not get rid of any of the variables. Therefore, this is false.

- The solution can be written as one value since x = y = -3. Therefore, this statement is true.
