Answer:

-(4 x^2 - 5 x + 28)

-4 x^2 + 5 x - 28

-1\/16 (8 x - 5)^2 - 423\/16

Step-by-step explanation:

any of these equations are equal to  3x^2+5x-7(x^2+4)​

The equivalent expression is -4 x² + 5 x - 28.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Given:

3x²+5x-7(x²+4)​

Now,

-(4 x² - 5 x + 28)

-4 x² + 5 x - 28

-1\/16 (8 x - 5)² - 423\/16

Hence, the  equivalent expression is -4 x² + 5 x - 28.

Answer:

[tex]\sqrt[3]{x-5}[/tex]=y

Step-by-step explanation:

f(x)=x^3+5

y=x^3+5

y-5=x^3

[tex]\sqrt[3]{x-5}[/tex]=y

Answer:

The linear function becomes:

y = 15x + 10

Here, 'x' is the number of hours, b=10 is the initial service fee i.e. $10, 15 is slope or rate of change, and 'y' is the cost.

Step-by-step explanation:

We know that the slope-intercept of a linear function is

[tex]y = mx+b[/tex]

where m is the slope and b is the y-intercept

Note: Slope is also termed as the 'rate of change'.

Given that Aron charges an initial service fee of 10$.

Thus, the y-intercept = b = 10

As the rate of change = 15$ per hour

so the slope = m = 15

Therefore, the linear function becomes:

[tex]y = mx+b[/tex]

y = 15x + 10

Here, 'x' is the number of hours, b=10 is the initial service fee i.e. $10, 15 is slope or rate of change, and 'y' is the cost.

For example, in one hour i.e. x = 1, the cost 'y' will be:

y = 15x + 10

y = 15(1) + 10

y = 25 + 10

y = $25

Therefore, in one hour (x=1), the cost will be: y = $25

Answer:

[tex]\frac{1}{32}[/tex]

Step-by-step explanation:

According to Reese's model, let the head of the coin represent male, and the tail represents female. The outcome can either be a male or a female.

Total outcome = 2

pr(male) = [tex]\frac{1}{2}[/tex]

pr(female) = [tex]\frac{1}{2}[/tex]

Therefore the probability of male equals the probability of females i.e [tex]\frac{1}{2}[/tex].

Therefore,

pr(a litter of 5 puppies will be males) = [tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex]

                                                           = [tex]\frac{1}{32}[/tex]

According to Reese's model, the probability that a litter of 5 puppies will be males is [tex]\frac{1}{32}[/tex].

The graph d represents the solution set of the inequalities 2x^2 < y and -x^2 + 5 > y

First, we represent the mathematical statements as an equation or inequalities

Mathematically, the statements in the questions are:

Where x and y represents the two numbers

So, we plot the graphs of 2x^2 < y and -x^2 + 5 > y

The graph d represents the solution set of the inequalities 2x^2 < y and -x^2 + 5 > y

Step-by-step explanation: Because I passed this on Acellus

Triangle ABD and ACD are congruent based on HL congruence theorem

Two figures are said to be congruent of they have the same shape and all the corresponding sides and angles are congruent.

The HL (hypotenuse leg) congruence theorem states that if the hypotenuse and one leg of a triangle is congruent to another triangle, then both triangles are congruent.

In triangle ABD and ACD;

BD = CD and AD ≅ AD

Hence Triangle ABD and ACD are congruent based on HL congruence theorem
