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.

Graph h(x)=7 sin x ?

DENIUS [597]

Answer:

The graph of h(x) is shown below.

Step-by-step explanation:

The given function is

$h(x)=7\sin x$

The general form of sine function is

$f(x)=a\sin(bx+c)+d$

Where, a is amplitude, b is period, c is phase shift and d is vertical shift.

So, the amplitude of the given function is 7, period is 1, phase shift is 0 and vertical shift is 0.

It means the minimum value of function is -7 and maximum value is 7.

Put x=0 in the given function.

$h(x)=7\sin (0)=7(0)=0$

Put $x=-\frac{\pi}{2}$ in the given function.

$h(x)=7\sin (-\frac{\pi}{2})=-7(1)=-7$

Put $x=\frac{\pi}{2}$ in the given function.

$h(x)=7\sin (\frac{\pi}{2})=7(1)=7$

Therefore the points on the function are (0,0), $(-\frac{\pi}{2},-7),(\frac{\pi}{2},7)$ .

The graph of function is shown below.

Given angle EFG has angle bisector FH, where EF = GF, find the value of y if EH = 5y + 10 and HG = 28 - y.

Whitepunk [10]

Answer:

y = 3

Step-by-step explanation:

*As seen in the photo, the fact that EF = GF and the bisector being there makes EH = HG.

5y + 10 = 28 - y

*Add y to both sides.

6y + 10 = 28

*Subtract 10 from both sides.

6y = 18

*Divide both sides by 6.

y = 3

pav-90 [236]

Answer:

The answer is 36 adults and 88 children.

Step-by-step explanation:

The two equations are:

x+y=124 and 5x+3y=444

Using substitution method:

5x+3(124+x)=444

5x+372-3x=444

2x=72

x=36

5(36)+3y=444

180+3y=444

3y=264

y=88

mafiozo [28]

Answer:

Step-by-step explanation:

To solve, we can use an equation finding the average of the siblings'ages.

$\frac{14 + 12 + x}{3} = 14 \\ \ 14 + 12 + x = 42 \\ x = 42 - 14 - 12 \\ x = 16$
