Answer:

The slope intercept form would be y = 9x - 7 and the standard form would be -9x + y = -7

Step-by-step explanation:

To write in either form, we need to start with point-slope form. To get slope-intercept we'll then solve for y.

y - y1 = m(x - x1)

y + 7 = 9(x - 0)

y + 7 = 9x

y = 9x - 7

Now for standard form, we do the same thing, but solve for the constant.

y - y1 = m(x - x1)

y + 7 = 9(x - 0)

y + 7 = 9x

-9x + y + 7 = 0

-9x + y = -7

A healthy human heart beats about 1,533,000 times a year. A sparrow's heart beats about 241,776,000 times in a year. About how m

Galina-37 [17]

Answer:

About 158 times

Step-by-step explanation:

Represent the rate of human heart with H and sparrow's heart with S

$H = 1,533,000\ times$

$S = 241,776,000\ times$

Required

Determine how many times faster is S than H

To do this, we simply divide S by H i.e.

$Number = \frac{S}{H}$

$Number = \frac{241,776,000}{1,533,000}$

$Number = 157.714285714$

$Number = 158$ --- approximated

<em>Hence, the sparrow's heart beats about 158 times faster than the human hearts</em>

Assume the parent function has been shifted up

mars1129 [50]

Answer:

If $y=(x-2)^2+4$ is the transformed function, then the parent function $y=x^2$ has been shifted up vertically by 4 units and horizontally right by 2 units

Step-by-step explanation:

Assume the function is $y=f(x)$ is the parent function.

A vertical shift,b units up will transform the function to $y=f(x)+b$ .

A horizontal shift $a$ units.

$y=f(x-a)+b$

For instance, if $y=x^2$ , b=4, and a=2 units.

Then the transformed function becomes:

$y=(x-2)^2+4$
