A function has a discriminant of -3. When graphed , how many -intercepts does it have?

a) 0
b) 2
c) 3
d) 1

Answer:

x = 7

y = 3

Step-by-step explanation:

[tex]\triangle ABC[/tex] is an equilateral triangle so that means all sides are equal

which means

[tex]AB= BC=AC\\\\7=x[/tex]

now in [tex]\triangle ACD[/tex]  is an isosceles triangle so that means opposite sides to the angles that have the same measure are equal

which means

[tex]AC=CD\\\\AC = y+4[/tex]

now remember that AC is a side of the equilateral [tex]\triangle ABC[/tex] so AC = 7

solving for y

[tex]7=y+4\\\\7-4 = y\\\\3=y[/tex]

so

[tex]x = 7\\\\y = 3[/tex]

Answer:

  a) $96.65

  b) $28,995

  c) 51.7% to principal; 48.3% to interest

Step-by-step explanation:

a) The monthly payment is given by the amortization formula:

  A = P(r/12)/(1 -(1 +r/12)^(-12t))

where P is the loan amount, r is the annual rate, and t is the number of years

Filling in the given values, we find ...

  A = $15,000(0.06/12)/(1 - (1 +0.06/12)^(-12(25))) ≈ $96.65

The monthly payment is $96.65.

__

b) The 300 payments total ...

  $96.65 × 300 = $28,995

The total amount paid is $28,995.

__

c) The percentage paid toward the principal is ...

  $15,000/$28,995 × 100% ≈ 51.7%

The remainder is paid toward interest: 100% -51.7% = 48.3%

51.7% is paid toward principal, 48.3% is paid for interest.

Answer:

from top: 60° , 45°, x = 5

Step-by-step explanation:

from top: 60° , 45°, x = 5

Top: Equilateral Triangle angle = 1/3 *180 = 60

Middle: Isosceles right Triangle base angle = 1/2 (180-90) = 45

bottom: Equilateral Triangle, sides are congruent x=5

Answer

its the third one.

Step-by-step explanation:

Answer:

The correct answer would be "A"

Step-by-step explanation:

You would take the total cost and divide it by however many ounces are there. In this case, take 9.72 and divide by 54. There you get 0.18 cents per ounce. You can go back and check it, so multiply 54 by 0.18 and you get 9.72.

Answer:

The value of x = 4

Step-by-step explanation:

Given the equation

[tex]5 + 9 = 6x - 10[/tex]

switch sides

[tex]6x-10=5+9[/tex]

Add 10 to both sides

[tex]6x-10+10=14+10[/tex]

Simplify

[tex]6x=24[/tex]

Divide both sides by 6

[tex]\frac{6x}{6}=\frac{24}{6}[/tex]

Simplify

[tex]x=4[/tex]

Therefore, the value of x = 4

when x is 1 the y value is 4. this means each times x moves 1 across the x axis, the y value will go up 4 on the y axis. this means the equation has a slope of 4

Answer:

288 inches ²

Step-by-step explanation:

Water color painting

Length = 23 inches

Width = 11 inches

Mat that adds 1 inch to each side of the length and the width

Mat

Length = 23 + 1 = 24 inches

Width = 11 + 1 = 12 inches

What is the area of the mat?

Area of the mat = length × width

[tex]5x^{2} + 34x - 22[/tex]

Step-by-step explanation:

-5x ( x + 6 ) = 4 ( x - 3 ) - 10

Distribute

[tex]-5x^{2} - 30x = 4x - 12 - 10[/tex]

Simplify,

[tex]-5x^{2} -30x = 4x -22[/tex]

Inverse operations;

[tex]-5x^{2} - 30x = 4x - 22\\ +30x +30x\\\\-5x^{2} = 34x - 22\\+5x^{2} +5x^{2}\\\\5x^{2} + 34x - 22[/tex]

Answer:

5x^2 + 34x - 22 = 0

Step-by-step explanation:

-5x(x+6) = 4(x-3)-10

-5x^2 - 30x = 4x - 12- 10

-5x^2 - 30x - 4x + 22 = 0

-5x^2 - 34x + 22 = 0

5x^2 + 34x - 22 = 0

Answer:

hi its 7

Step-by-step explanation:

There are 7 numbers in the given sequence.

Here,

The last two entries are 37 and 60 in the order.

The first entry is 4.

What is Sequence?

A sequence is an enumerated collection of objects in which repetitions are allowed and order matters.

Now,

First term is 4.

Last two terms are 37 and 60.

Condition is given as, we add any two consecutive entries to get the very next entry.

For find the third number from the last is as;

x + 37 = 60

x = 60 -37

x = 23

Continuing this pattern we get the sequence;

4, 5, 9, 14, 23, 37, 60

Clearly, There are 7 entries in the given sequence.

Answer:

''Multiply k by 5, and then add 3 to the product'' means:

Step-by-step explanation:

When we multiply k by 5, we get the product of k and 5.

In other words,

Add 3 to the product means we need to add 3 to 5k.

In other words,

Therefore,

''Multiply k by 5, and then add 3 to the product'' means:

Answer:

a and d

Step-by-step explanation:

5x = 20

5/5x = 20/5

x = 4

8x = -32

x = -4

-4x = 16

x = -4

x/2 = 2

2*x/2=2*2

x = 4

x/4 = 16

4*x/4 = 16*4

x = 64

The equations 5x = 20 and x/2 = 2 are that have a solution of 4 which is the correct answer would be options (A) and (D).

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

We have to determine the solution of all the given equations.

5x = 20

x = 20/5

Apply the division operation, and we get

x = 4

This is the required solution.

8x = -32

x = -32/8

Apply the division operation, and we get

x = -4

-4x = 16

x = 16/4

x = -4

x/2 = 2

2×x/2=2×2

x = 4

This is the required solution.

x/4 = 16

4×x/4 = 16×4

x = 64

Therefore, the correct answer would be options (A) and (D).

Answer:

14

Step-by-step explanation:

The product of two consecutive odd numbers equals 55 plus ten times the even number which is between them. Find the even number.​

Let the two odd consecutive integer be x and x+2

Let the even number between then be x+1

If the product of two consecutive odd numbers equals 55 plus ten times the even number, then;

(x)(x+2) = 55 + 10(x+1)

Expand

x² + 2x = 55 + 10x + 10

x² -8x -65 = 0

x² - 13x+5x - 65 = 0

x(x-13)+5(x- 13) = 0

(x-13) (x+5) = 0

x = 13 and -5

Since the even number is x + 1

Even number = 13 + 1 = 14
