Step-by-step explanation:

A) Discriminant = b² - 4ac = (12)² - 4(9)(4) = 144 - 144 = 0

B) Since the discriminant is 0, this means the equation only has one root.

C) The root is real in this case since the discriminant is not negative. Otherwise, we would have two imaginary roots if it were (remember that complex roots come in pairs)

Step-by-step explanation:

5 x 8 = 40

2 x 2 = 4

4 x 7 = 28

40 + 4 + 28 = 72

Answer:

Step-by-step explanation:

the picture is telling us that the angles Q and R are equal so set them equal

9x-17 = 4x + 28

5x = 45

x = 9

Answer:

D. square root of 7 to the power of 3

R. b=6/8

Answer:

The number of days in y hours is y/24

Step-by-step explanation:

Here, we want to write an expression

Mathematically;

1 day = 24 hours

? days = y hours

? days = (y * 1)/24

? days = y/24

Calculation. Formula.

P (1 + r/n)^(nt)

Calculate accrued amount. Principal + Interest. A = P(1 + r)t

Calculate principal amount. Solve for P in terms of A. P = A / (1 + r)t

Calculate principal amount. Solve for P in terms of I. ...

Calculate rate of interest. As a decimal. ...

Calculate rate of interest. As a percent. ...

Calculate time. Solve for t.

The solution for P (Principal amount) in a compound interest Formula is; P = A/(1+ r)^t.

By convention, the formula for calculating the compound interest is;

On this note, it follows that; the principal amount, P can be calculated by dividing both sides of the equation by the expression; (1+ r)^t.

Ultimately, the solution for P is; P = A/(1+ r)^t.

Answer:

52

Step-by-step explanation:

Let each of the base angles = x

x + x + 76 = 180                 Subtract 76 from both sides

x + x = 104                         Combine the 2 xs

2x = 104

x = 52

Each base angle has a measure of 52

Answer:

The number is -341

Step-by-step explanation:

Let the three digit number be represented as 100a+10b+c

Given

2a -b = 2 ---(1)

a = 3c ----(2)

100a+10b+c - 100c -10b -a = 594

99a -99c = 594 ---(3)

From 2 & 3 , we get -

99*a - (99*3*a) = 594

99*2 a = 594

a = -3

a = 3c, c = -1

2*-3 -b = 2, b = -4

Number is -341

Answer: tell me if i am wrong

p = 304

Step-by-step explanation:

Given p is inversely proportional to q² then the equation relating them is

p = [tex]\frac{k}{q^{2} }[/tex] ← k is the constant of proportion

To find k use the condition p = 19 when q is 8, then

19 = [tex]\frac{k}{8^{2} }[/tex] =[tex]\frac{k}{64}[/tex]  ( multiply both sides by 64 )

k = 1216

p = [tex]\frac{1216}{q^{2} }[/tex] ← equation of proportion

When q = 2, then

p =  [tex]\frac{1216}{2^{2} }[/tex]=[tex]\frac{1216}{4}[/tex]=304

These 2 angles are alternate exterior so they're equal to each other.

x + 127 = 125

x = 125 - 127

x = -2

Answer:

B

Step-by-step explanation:

A linear function is described by a x term to the power of 1 or even 0. A function when x is to the second power is most usually not a linear function.

In answer A, you have x multiplied against -3x. This will cause an x squared term, so this is not a linear function.

In answer B, you have 1/2 multiplied against x, which is a regular x term subtracted by 2x, causing a regular x term, meaning this function is linear. However, in the small possibility it is not, we will keep going.

In answer C, there is an x squared term so this is not linear.

In answer D, the expression has 1/2x times 2x, which will cause an x squared term.

Thus, the answer is B, which is the only equation without an x squared term.
