Sydney planted 5/9 of her fall flowers. she had 63 unplanted flowers to start how many flowers does she have left to plant

Gwar [14]

Since Sydney has planted 5/9 of her flowers and there were 63 flowers that are left unplanted, the first thing we are going to determine is the number of flowers that were planted. To do this, we just have to do the cross multiplication process.
So 5/9 x ?/63 = 35. Therefore, the number of plants planted were 35. To start, Sydney has a total of 100 flowers to be planted. That would be 35 + 65 is 100.

What is this function written in vertex form? f(x) = (x –1)2 – 7 f(x) = (x 1)2 – 7 f(x) = (x –1)2 – 5 f(x) = (x 1)2 – 5

Maslowich

The vertex form of all expressions is given below.

We have given that the expressions

We have to write the function in vertex form.

<h3>What is the vertex form of the equation?</h3>

The vertex form of a quadratic function is given by f (x) = a(x - h)^2 + k, where (h, k) is the vertex of the parabola.

Therefore the first equation

$f(x)=(x-1)^2-7$

it can be written as

$f(x)=1(x-1)^2+(-7)$

The second equation can be written as

$f(x) = (x+1)^2 -7$

vertex for is,

$f(x)=1(x-(-1))^2+(-7)$

The third equation is,

$f(x) = (x -1)^2 - 5$

Vertex form is,

$f(x)=1(x-1)^2+(-5)$

Forth equation is,

$f(x) = (x +1)^2 +(- 5)$

Vertex form is,

$f(x) =1 (x -(-1))^2 +(- 5)$

A furnace delivers 8.0 × 104 btu per hour. how many kilocalories per hour is this?

vazorg [7]

For this case the first thing you should know is the following unit conversion.
1 BTU = 0.25 Kilocalories
We then have the following numerical value:
$8.0 * 10 ^ 4 \frac{BTU}{h}$
Applying the conversion of units we have:
$8.0 * 10 ^ 4 \frac{BTU}{h} * 0.25 \frac{Kcal}{BTU}$
Canceling units we have:
$20000 \frac{Kcal}{h}$
Answer:
This is 20000 kilocalories per hour
$20000 \frac{Kcal}{h}$

Graph thee line that represents this equation:<br>y+2=1/2(x+2)

Yuliya22 [10]

Answer:

$y = \frac{1}{2} x - 1$

Explanation:

The first pic shows the line graphed, while the second pic shows how to turn the equation into proper slope-intercept form.

The only steps the second pic is missing however, is flipping the sides around to be better understood (optional), and more importantly subtracting 2 on both sides in order to move it to the other side, to get 2y = x - 2. And dividing the 2 on both sides to get y by its self, to get:

y = (x-2)/2 , or y = 1/2 x - 2/2 , which if you notice 2/2 makes it equal to one whole so your answer is y = 1/2 x - 1 .
