What is y=x+6 y=-2x-3

2 answers:

3 0

X=-3 because first substitute the value of y into the original equation -2x-3=x+6 then isolate the variables -2x-x=6+3 which is -3x=9 then we can divide x=9/-3 which =-3

Graph h(x)=7 sin x ?

dedylja [7]

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.

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

The graph of function is shown below.

What is the percent of change?

Xelga [282]

Percent means parts out of 100
x%=x/100

find change
10 to 60=50 (60-10=50)

percent change=change/originla
original=10
change=50
50/10=x%
5/1=x/100
multiply both sides by 100
500=x

answer is 500%
