Answer:

y = 4.5 x

Step-by-step explanation:

If this is a proportional relationship, we can find the slope

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

m = (27-0)/(6-0)

m = 27/6

m=9/2

The slope is 9/2

The y intercept, where it crosses the y axis is 0

Using the slope intercept form of the equation y=mx+b

y = 9/2 x+0

y =9/2x

It wants the decimal form

y = 4.5 x

Identify the degree, type, and lead coefficient of f(x) = x2 + 3x - 4x + 6x* - 1.

bonufazy [111]

Answer:

2, quadratic, 1

Step-by-step explanation:

Degree is the highest power which is 2 then the lead coefficient is the constant multiplying the highest power so for x^2 it is 1 and the type of equation is what is it, linear, quadratic, cubic, etc. For this it is quadratic because x^2 means its a parabola.

A florist has 49 red roses and 63 white roses. The florist wants to put an equal number of red roses in each centerpiece, along

RideAnS [48]

7..
49 can be equally divided by seven, which means there would be 9 red roses in each center piece. And 63 can be equally divided by 7 which means there would by 7 white roses in each center piece.
hope this helps

The wind-chill index W is the perceived temperature when the actual temperature is T and the wind speed is v, so we can write W

melamori03 [73]

Answer:

hello your question is incomplete attached below is the complete question

estimating: Ft( -15,40 ) = ( 1.2 + 1.4 ) / 2 = 1.30⁰c

when the actual temperature is -15⁰c and the wind speed is 40 km/h the apparent temperatures increase by 1.3⁰c that the actual temperature rises

estimating: Fv ( -15,40 ) = (-0.2 + -0.1 ) / 2 = -0.15⁰c

when the actual temperature -15⁰c and the wind speed is 40 km/h the apparent temperature decreases by about 0.15⁰c for every km/h that the wind speed

Step-by-step explanation:

A) Estimating the values of Ft(−15, 40) and fv(−15, 40)

attached below is a detailed solution

To estimate the value of Ft( -15,40 ) we have to take an average value hence Ft ( -15,40 ) = ( 1.2 + 1.4 ) / 2 = 1.30

and this means that when the actual temperature is -15⁰c and the wind speed is 40 km/h the apparent temperatures increase by 1.3⁰c that the actual temperature rises

To estimate the value of Fv(-15,40 ) we have to take an average value

hence Fv ( -15,40 ) = (-0.2 + -0.1 ) / 2 = -0.15

and this means that when the actual temperature -15⁰c and the wind speed is 40 km/h the apparent temperature decreases by about 0.15⁰c for every km/h that the wind speed
