Answer:

y-intercept (0, -3) and x-intercept (3/2, 0)

Step-by-step explanation:

y + 5 =2(x + 1)

y + 5 =2x + 2

subtract 5 from both side

y =2x -3

-3 is the y-intercept because in y=mx+b, b is the y-intercept and it always starts at 0.

To find the x-intercept, we need to plug in 0 for y in y =2x -3

0=2x -3

add 3 to both sides

2x=3

divide both sides by 2

x=3/2 and so the x-intercept is 3/2 and it always starts at 0.

Yuki bought a pound of confetti for \$12$12. What is the price, in dollars, per ounce of confetti? There are 1616 ounces in 11 p

Ber [7]

Answer:

Price $0.75 per ounce of confetti

Step-by-step explanation:

Given the statement: Yuki bought a pound of confetti for $12.

⇒ $1 pound = \$ 12$ ......[1]

Also, it is given that there are 16 ounces in 1 pound.

⇒ 16 ounces = 1 pound .....[2]

To calculate the price, in dollars per ounce of confetti.

From [1] and [2] we have;

$16 ounces = \$12$

then;

1 ounces = $\frac{12}{16} = \frac{3}{4} = \$0.75$

Therefore, the price, in dollars per ounce of confetti is, $0.75 per ounce.

Solve the following algebraic equation using appropriate

Neko [114]

( x + 1 )/ 3 = x + 2
Multiply 3 on both sides
x + 1 = 3x + 6
Subtract 6 on both sides
x - 5 = 3x
Subtract x from both sides
-5 = 2x
Divide 2 from both sides
x = -2.5

What is the inverse of y=pi/2+sin x

Alekssandra [29.7K]

Answer:

$f^{-1}(x)=\sin ^{-1}(x-\frac{\pi}{2})$

Step-by-step explanation:

The given function is

$y=\frac{\pi}{2}+\sin x$

To find the inverse of this function, we interchange x and y.

$x=\frac{\pi}{2}+\sin y$

we now solve for y.

$x-\frac{\pi}{2}=\sin y$

Take the sine inverse of both sides to obtain;

$\sin ^{-1}(x-\frac{\pi}{2})=y$

Hence the inverse of the given function is;

$f^{-1}(x)=\sin ^{-1}(x-\frac{\pi}{2})$

where $\frac{\pi}{2}-1\le x\le \frac{\pi}{2}+1$
