The temperature in degrees Celsius, c, can be converted to degrees Fahrenheit, f, using the equation f = StartFraction 9 Over 5 EndFraction c + 32. Which statement best describes if the relation (c, f) is a function?
It is a function because –40°C is paired with –40°F.
It is a function because every Celsius temperature is associated with only one Fahrenheit temperature.
It is not a function because 0°C is not paired with 0°F.
It is not a function because some Celsius temperatures cannot be associated with a Fahrenheit temperature.

Answers

3. The points (15,21) and (25,35) form a proportional relationship.
a) Find the slope of the line through the points.
b) Which graph represents this relationship?

Answers

Answer:the letter is c because it the only one that is lined up and I got it right trust me

Step-by-step explanation:

The slope of the line passing through (15,21) and (25,35) is 7/5.

What is slope?

The slope of a line is a measure of its steepness.

Given that, the points (15,21) and (25,35) form a proportional relationship.

Slope = (y2-y1)/(x2-x1)

= (35-21)/(25-15) = 14/10 = 7/5

The equation of a line passing through these two points are;

y - y1 = [(y2−y1)/(x2−x1)](x - x1)

y - 21 = 7/4(x - 25)

y = 7x/4 - 14

Hence, the slope of the line = 7/5

two angles in a triangle have measures of 62 degrees and 15 degrees. What is the measure of the third angle.

A.92 degrees

B.47 degrees

C.77 degrees

D.103 degrees

Answers

Answer:

the answer is 103

Step-by-step explanation:62°+15°=77° degrees

Then it is 180° - 77° degrees

180°-77°=103°

The measure of the third angle of a given triangle is 103°.

Given that the measure of two angles is 62° and 15°.

We need to find the measure of the third angle.

What is the angle sum property of a triangle?

The angle sum property of a triangle states that the sum of interior angles of a triangle is 180°.

Let the measure of the third angle be x.

Now,  62°+15°+x=180°

⇒x=180°-77°

⇒x=103°

Therefore, the measure of the third angle is 103°.

Which of the following equations has a positive slope?

y= -4

Answers

Answer: i say number 3

Step-by-step explanation:

because i pay attention in math class

The equation y = x has the positive slope.

What is Slope?

Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.

Slope can also be defined as the tangent of the angle that the line is making with the positive X axis.

Given three equations which are in the form of slope intercept form of the equation of a line.

Slope intercept form of a line is y = mx + d, where m is the value of the slope and d is the value of the y intercept.

y intercept is the y coordinate of the point on the line where it touches the Y axis. The x coordinate will be 0 there.

Equations given are

y = -x + 0 ⇒ Slope = -1

y = x ⇒ Slope = 1

y = -4 ⇒ Slope = 0

So y = x has the slope equal to 1 which is positive.

Hence the equation y = x has the positive slope.

How do you write 5y<3 without exponents?

Answers

Answer:

When an exponent is 1, the base remains the same. a 1 = a . When an exponent is 0, the result of the exponentiation of any base will always be 1, although some debate surrounds 0 0 being 1 or undefined. For many applications, defining 0 0 as 1 is convenient.. a 0 = 1 . Shown below is an example of an argument for a 0 =1 using one of the previously mentioned exponent laws.
