Answer:

Step-by-step explanation:

If you think of the equation as an equation for a line.

where

=5/9(−32)

(

−

)

=5/9−5/9(32)

−

(

)

you can see the slope of the graph is 5/9

, which means that for an increase of 1 degree Fahrenheit, the increase is 5/9

of 1 degree Celsius. Therefore, statement I is true.

This is the equivalent to saying that an increase of 1 degree Celsius is equal to an increase of 9/5

degrees Fahrenheit. Since 95

= 1.8, statement II is true.

On the other hand, statement III is not true, since a temperature increase of 9/5

degrees Fahrenheit, not 5/9

degree Fahrenheit, is equal to a temperature increase of 1 degree Celsius.

The final answer is D.

Solve by any method (graphing, substitution or linear combination)

Lostsunrise [7]

Answer:

b) (5, -3)

Step-by-step explanation:

The given equations are;

$y=x-8...(1)$

$2x+3y=1...(2)$

I prefer using substitution because of the first equation.

Put equation (1) into equation (2) to obtain;

$2x+3(x-8)=1$

We expand the parenthesis to obtain;

$2x+3x-24=1$

Group similar terms to get;

$2x+3x=1+24$

Simplify

$5x=25$

Divide through by 5;

$x=\frac{25}{5}$

$\Rightarrow x=5$

Put $x=5$ into equation (1) to get;

$y=5-8$

$\Rightarrow y=-3$

The solution is (5,-3).

The correct answer is B

120% as a fraction in simplest form

kkurt [141]

6/5 because how do you convert a percentage to a decimal? First you move the decimal points over by two, so you start off with 120 and end with 1.20. There are many ways you can go from here. If you have a graphing calculator like i do, then you type in 1.20 hit the "math" button, hit enter and a fraction already in its simplest form is given. I hope this helps, have a great day.

Jose had a rectangular piece of paper that

jekas [21]

Answer:

B. 2800 sq mm

Step-by-step explanation:

Given the following data;

Length = 80 mm

Width = 70 mm

Area of rectangle is given by the formula;

Area of rectangle = length * width

Substituting into the formula, we have;

Area of rectangle = 80 * 70

Area of rectangle = 5600 mm²

Since the paper (area of rectangle) was halved, we would divide by 2;

Area of each half = 5600/2

Area of each half = 2800 sq mm.
