Answer:

f = -5/3.

Step-by-step explanation:

We want to isolate f on the left side of the equation.

To do this we multiply both sides by -4/3 , because -3/4 * -4/3 = 1 giving us 1f.

-4/3 * -3/4 f = 5/4 * -4/3

-12/-12 f = 5/4 * -4/3

1 f = -20/12

f = - 5/3.

F= -1 2/3 or 5/3

In order to find the answer all you have to do is multiply both sides by -4/3.

-3/4f × -4/3 = f

-4/3 × 5/4 = -20/12

-20/12 simplified is -5/3 or -1 2/3

twice the number of donuts was only 6 less than 24 times the number of cream puffs. 10 times the number of cream puffs was only

Karolina [17]

donuts and cream puffs were 45 & 4 respectively !

Step-by-step explanation:

Here we have , twice the number of donuts was only 6 less than 24 times the number of cream puffs. 10 times the number of cream puffs was only 5 less than the number of donuts We need to find how many donuts and cream puffs were there . Let's find out:

Let number of donuts and cream puffs are x & y respectively ! So ,

twice the number of donuts was only 6 less than 24 times the number of cream puffs

According to this statement equation is :

⇒ $2x=24y-6$

⇒ $x=12y-3$ ................(1)

10 times the number of cream puffs was only 5 less than the number of donuts

According to this statement equation is :

⇒ $10y= x-5$

⇒ $x=10y+5$ ................(2)

Equation (1) & (2) :

⇒ $12y-3=10y+5$

⇒ $2y=8$

⇒ $y=4$

Putting $y=4$ in $x=12y-3$ :

⇒ $x = 12(4)-3$

⇒ $x = 45$

Therefore , donuts and cream puffs were 45 & 4 respectively !

Sketch the graph of y = (x + 3)2 – 4 and identify the axis of symmetry.

Sloan [31]

Answer: Thought I’d return the favor and help u with this question! But anyways, the axis of symmetry is at x = -3.

Explanatio: This can be found by looking at the basic form of vertex form:

y = (x - h)^2 + k

In this basic form the vertex is (h, k). By looking at what is plugged into the equation, it is clear that h = -3 and k = -4. This means the vertex is at (-3, -4).

It is a fact that the axis of symmetry is a vertical line of x = (vertex value of x). So we can determine that the axis of symmetry is at x = -3

i hope this helps u
