Answer:

a reflection over the x-axis

Step-by-step explanation:

say you plotted (1,1) and the plotted (-1,1). The result would be a reflection over the x-axis.

Verizon [17]

Answer:

first question :

The missing value is the slope

let me be the slope

m= (3-1)/(0-(-1)) = 2

so y= 2x+3

secong question :

the missing value is the y-intercept

wich the image of 0 *it's -1

so : y= 3x-1

third question

draw the two functions

you'll find that they intercept at (4;11)

What are the x-intercepts of y=sin(x)+1

Stella [2.4K]

Answer:

$x = n\pi + ( { - 1)}^{n} \times \frac{3\pi}{2}$

Step-by-step explanation:

We want to find the x-intercepts of

$y = \sin(x) + 1$

At x-intercept, y=0.

$0 = \sin(x) + 1$

$\sin(x) = - 1$

Take sine inverse of both sides to get:

$x = { \sin }^{ - 1} ( - 1)$

$x = n\pi + ( { - 1)}^{n} { \sin }^{ - 1} ( 1)$

The x-intercepts are:

$x = n\pi + ( { - 1)}^{n} \times \frac{3\pi}{2}$

for n being an integer

What is 7/9 written as a decimal please explain!!

IrinaK [193]

7/9 as a decimal is 0.777.

7/9 is basically saying 7 divided by 9.
Since 9 doesn't at all go into 7, we have to make a decimal using long division.
So because a decimal isn't a whole number, we put 0.(blank) at the top in place of the regular number.
After, you just continue with the regular long division, but every time the divisor doesn't go into the number from the subtraction, you bring down a zero.

Sorry if this was kind of confusing!
Just watch a video on it if this didn't help.
