buys 3 tulips and 5 daffodils. The total cost is $41.75. The bills do not list a per item price. How much does one tulip and one daffodil cost?

Kako put 3 4/10 bags of fertilizer on the front lawn and 2 2/3 bags of fertilizer on the back lawn. How many bags of fertilizer

earnstyle [38]

Ok. Since the fractions aren't the same, we have to make them common. They both have 30 in common.
4/10 = 12/30 I multiplied this 4 by 3 since I did 10 times 3.
2/3 = 20/30 Same with this one. Since 3 times 10, 2 times 10
Now you add the things to get 32/30, simplify to 1 2/30, and again to get 1 1/15.
Now add
3+2+1/15 = 6 1/15
He used 6 1/15 bags of fertilizer.

Help with those three please!!

Answer:

Part 1) Option A. The axis of symmetry is x=4

Part 2) Option C. minimum

Part 3) Option A. (4,-4)

Part 4) Option B. (2,0) and (6,0)

Step-by-step explanation:

we have

$f(x)=x^{2}-8x+12$

Part 1) What is the axis of symmetry of the parabola described by the equation above?

we know that

The equation above is a vertical parabola open upward

The axis of symmetry is the x-coordinate of the vertex

Find the vertex of the parabola (convert the equation in vertex form)

$f(x)-12=x^{2}-8x$

$f(x)-12+16=x^{2}-8x+16$

$f(x)+4=x^{2}-8x+16$

$f(x)+4=(x-4)^{2}$

$f(x)=(x-4)^{2}-4$ ----> equation in vertex form

The vertex of the parabola is (4,-4)

so

The axis of symmetry is x=4

Part 2) The vertex of the equation above is also

we know that

The equation above is a vertical parabola open upward

therefore

The vertex is a minimum

Part 3) What is the vertex of the parabola described by the equation above

we know that

The equation of the parabola into vertex form is equal to

$f(x)=(x-4)^{2}-4$

therefore

The vertex of the parabola is (4,-4)

Part 4) What are the x-intercepts of the parabola described by the equation above

we know that

The x-intercepts are the values of x when the value of y is equal to zero

so

$f(x)+4=(x-4)^{2}$

f)x)=0

so

$4=(x-4)^{2}$

take square root both sides

$(x-4)=(+/-)2$

$x=4(+/-)2$

$x=4(+)2=6$

$x=4(-)2=2$

therefore

The x-intercepts are

(2,0) and (6,0)
