Answer:

1. unknown

2. 1/4h+3

3. a=2

4. x=8

5. p=30

Step-by-step explanation:

32k+24= not sure where you are going with this.

(3/4h+4)-(1/2h+1). you can rewrite it so it shows numbers and variables together.

(3/4h-1/2h) -(4+1).  

3/4h-1/2h = 1/4h. &

the subtract changes the plus to minus, so it is 4-1= 3

So, 1/4h+3.

____________________________________________

5a-12=-2

you want to have the letter a, by itself on one side of the = sign.

to do that, you need to do the opposite on both sides.

start with -12. (add 12 to both sides)

5a -12 + 12=-2+12

5a=10

then divide both sides by 5

5a/5=10/5

a= 2

____________________________________________

-5(x-4)=-30

take -5 times x and -5 times -4

-5x + 20=-30 (when you multiply a negative times a negative, it is a positive. )

opposite to both sides again. -5x+20-20=-30-20

-5x=-40

then divide both sides by -5

-5x/-5=-40/-5

x=8

The equation is P=21+9. P for points Alice has.   p=30

If the discriminant is negative then the quadratic has
zepelin [54]

Answer:

No <em>real</em> solutions (or has two complex roots)

Step-by-step explanation:

The discriminant, <em>b</em>² - 4<em>ac</em>, is the expression (<u><em>radicand </em></u>) of the quadratic equation:

x = \frac{-b +/- \sqrt{b^{2}-4ac} }{2a}.

The value of the discriminant determines the <u>nature</u> and the <u>number of solutions</u> given by the quadratic equation.

A discriminant with a negative value (or b² - 4ac < 0 ) means that the quadratic equation has no real solutions or two complex solutions. Quadratic equations with a negative discriminant also have no x-intercepts; thus, its graph will not cross the x-axis.

What is the minimum y value of the following quadratic function? f(x) = x2 - 6x + 8
tia_tia [17]

Answer:

14

Step-by-step explanation:

k

=

c

−

b

2

4

a

We know that

a

=

1

,

b

=

−

8

and

c

=

2

, so let's substitute:

k

=

2

−

(

−

4

(

1

)

=

−

64

4

=

−

16

=

−

14

.

So, we have

min

=

−

14

. Let's check:

graph{(x^2 - 8x + 2 - y)(-14 -y)=0 [-11.82, 20.22, -15.38, 0.64]}
