How do I solve special right triangles?

Answer:

y > 0 best describes the range of the function f(x) = 2(3)x. A function whose value is a constant raised to the power of the argument, especially the function where the constant is e

Step-by-step explanation:

Using exponential function concepts, it is found that the range of the function after it has been reflected over the x-axis is given by:

all real numbers less than 0.

It is modeled by:

[tex]y = ab^x + c[/tex]

In which:

In this problem, a reflection over the x-axis means that it was multiplied by -1, hence the range will be (-infinity, 0), hence the correct option is;

all real numbers less than 0.

Answer:

If both expressions have the same value after substituting and simplifying for x = 6 and x = 10, then they are equivalent. Substitute 6 for each variable, x, in both expressions. Use the order of operations to simplify both expressions. The value of both expressions is 88. Now, substitute 10 for each variable, x, in both expressions. Use the order of operations to simplify both expressions. The value of both expressions is 120. Therefore, the expressions are equivalent.

Step-by-step explanation:

got it right!

The two expressions are equivalent.

Important information:

The values of both expression for [tex]x=6[/tex] are:

[tex]8(6)+40=48+40[/tex]

[tex]8(6)+40=88[/tex]

And

[tex]8(6+5)=8(11)[/tex]

[tex]8(6+5)=88[/tex]

The values of both expression for [tex]x=10[/tex] are:

[tex]8(10)+40=80+40[/tex]

[tex]8(10)+40=120[/tex]

And

[tex]8(10+5)=8(15)[/tex]

[tex]8(10+5)=120[/tex]

Since the values of both expressions are equal for each of the values [tex]x=6[/tex] and [tex]x=10[/tex]. Therefore, the two expressions are equivalent.

D y= ax^2 + bx+c = 0

Step-by-step explanation:

The standard form of a quadratic equation is

ax^2 + bx+c = 0

x = -b/2a is the equation for the line of symmetry

a quadratic is a parabola, but that is not the standard form

vertex is the minimum or maximum of the parabola

Answer:

Step-by-step explanation:

Given the function [tex]f(x)=-3x^2 +75[/tex]

The zeros of the function are the values of x for which f(x)=0.

[tex]f(x)=-3x^2 +75=0\\-3x^2 +75=0\\-3(x^2-25)=0\\$Divide both sides by -3\\x^2-25=0\\$Add 25 to both sides\\x^2-25+25=0+25\\x^2=25\\$Take the square root \\\sqrt{x^2}=\pm \sqrt{25}\\ x=\pm 5[/tex]

The zeros of f(x) are therefore 5 and -5.

Answer:

An equation for this would be : 36=3+x+3+X+5+5

the simplified version would be: 20=2x

The value of x = 10 feet

Step-by-step explanation:

Since perimeter is all the sides added together, and 36 ft is the perimeter,

think of a rectangle, 2 sides would be 3+x and the other 2 would be 5.

thus,

36=3+x+3+x+5+5

now add all like terms and you get 36=16+2x

subtracting 16 on both sides,

20=2x

dividing by 2 both sides,

x=10 feet.

Answer:

(-4,7)

Explanation:

I graphed the two equations with a graphing tool.

The first equation forms a parabola.

The second equation is linear.

The graphed equations intercept at two points. Since the question asked for one, then one solution of the system is (-4,7).

Answer:

(- 4, 7 ) and (2, - 5 )

Step-by-step explanation:

Given the 2 equations

y = x² - 9 → (1)

y = - 2x - 1 → (2)

Substitute y = x² - 9 into (2)

x² - 9 = - 2x - 1 ( subtract - 2x - 1 from both sides )

x² + 2x - 8 = 0 ← in standard form

(x + 4)(x - 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 4 = 0 ⇒ x = - 4

x - 2 = 0 ⇒ x = 2

Substitute these values into (2) for corresponding values of y

x = - 4 → y = - 2(- 4) - 1 = 8 - 1 = 7 ⇒ (- 4, 7 )

x = 2 → y = - 2(2) - 1 = - 4 - 1 = - 5 ⇒ (2, - 5 )

Answer:

Step-by-step explanation:

Given

y = 3

Required

Which pair of expression are equal

To get the pair of expression that are equal; we simply substitute 3 for y in each of the expressions

3 (4 - y) -7 and 5 + 3y

Substitute 3 for y in 3 (4 - y) -7

This gives 3(4 - 3) -7

= 3(1) - 7

= 3 - 7

= -4

Then Substitute 3 for y in 5 + 3y

This gives  5 + 3(3)

= 5 + 9

= 14

-4 and 14 are not equal

---------------------------------------------------------------------------------------

9 + y + 4y - 2 - 3y; -2y + 7

Substitute 3 for y in 9 + y + 4y - 2 - 3y

This gives 9 + 3 + 4(3) - 2 - 3(3)

= 9 + 3 + 12 - 2 - 9

= 13

Then Substitute 3 for y in -2y + 7

This gives  -2(3) + 7

= -6 + 7

= 1

13 and 1 are not equal

---------------------------------------------------------------------------------------

5 + y - 2 - 6y + y; 8y + 3

Substitute 3 for y in 5 + y - 2 - 6y + y

This gives 5 + 3 - 2 - 6(3) + 3

= 5 + 3 - 2 - 18 + 3

= -9

Then Substitute 3 for y in 8y + 3

This gives  8(3) + 3

= 24 + 3

= 27

-9 and 27 are not equal

---------------------------------------------------------------------------------------

2y + 7 + y - 2 + y; 4y + 5

Substitute 3 for y in 2y + 7 + y - 2 + y

This gives 2(3) + 7 + 3 - 2 + 3

= 6 + 7 + 3 - 2 + 3

= 17

Then Substitute 3 for y in 4y + 5

This gives  4(3) + 5

= 12 + 5

= 17

17 and 17 are equal

Hence, Option D is correct

Answer: 2y + 7 + y - 2 + y; 4y + 5

Step-by-step explanation:

A

The factored equivalent of x² - 5x + 4 is option A: (x - 1)(x - 4).

To factor the quadratic expression x² - 5x + 4, we need to find two binomials that, when multiplied, will result in the given expression.

We can start by looking for two numbers whose product is 4 (the constant term) and whose sum is -5 (the coefficient of the x term).

The numbers that satisfy these conditions are -1 and -4, as (-1)(-4) = 4 and -1 + (-4) = -5.

Using these numbers, we can express the quadratic expression as:

x² - 5x + 4 = (x - 1)(x - 4)

Therefore, the factored equivalent of x² - 5x + 4 is option A: (x - 1)(x - 4).
