Answer:

a) y = -3/10x + 24.

Step-by-step explanation:

2.5y + 0.75x = 60

2.5y = -0.75x + 60

Divide through by 2.5:

y = -3/10x + 24.

Answer:

The domain of [tex](f\cdot g)(x)[/tex] is [tex]R-\{-2,2\}[/tex].

Step-by-step explanation:

Given that,

[tex]f(x)=\frac{2}{x^2-4}[/tex] and

[tex]g(x)=x^2+4x+4.[/tex]

The function f(x) is not defined when the denominator equals zero, i.e

[tex]x^2-4=0[/tex]

[tex]\Rightarrow x=\pm2[/tex]

So, the domain of f(x) is all real number except [tex]\pm2[/tex].

[tex]f(x)=\frac{2}{x^2-4}[/tex]

for [tex]x\in R-\{-2,2\}\;\cdots(i)[/tex]

The function g(x) is defined for all real numbers.

[tex]g(x)=x^2+4x+4[/tex]

for [tex]x\in R\;\cdots(ii)[/tex]

As [tex](f\cdot g)(x)=f(x)\cdot g(x)[/tex]

[tex]\Rightarrow(f\cdot g)(x)=\left(\frac{2}{x^2-4}\right)\cdot \left(x^2+4x+4\right)[/tex]

[tex]\Rightarrow \frac{2(x^2+4x+4)}{x^2-4}[/tex]

this resulting function have the common domain of f(x) and g(x).

So, from equation (i) and (ii), the domain of [tex](f\cdot g)(x)[/tex] is all real numbers except [tex]\pm2[/tex]. i.e

[tex](f\cdot g)(x)=\frac{2(x^2+4x+4)}{x^2-4}[/tex]  for [tex]x\in R-\{-2,2\}[/tex]

The translation rule

(x, y ) → (x + 3, y - 2 )

Means add 3 to the original x- coordinate and subtract 2 from the original y- coordinate, thus

A(- 4, 1 ) → A'(- 4 + 3, 1 - 2 ) → A'(- 1, - 1 )

B(1, 1 ) → B'(1 + 3, 1 - 2 ) → B'(4, - 1 )

C(1, - 2 ) → C'(1 + 3, - 2 - 2 ) → C'(4, - 4 )

D(- 4, - 2 ) → D'(- 4 + 3, - 2 - 2 ) → D'(- 1, - 4 )

Answer:

h(3) = -4

h(-3) = -16

Step-by-step explanation:

The formula is h(x)= 2x-10. So you have to plugin 2x-10 into h(3). Same thing for h(-3).

h(3) = 2*3-10

h(3) = -4

h(-3) = 2*-3-10

h(-3) = -16

Answer:It is option c. Because when we substitute x for -1 we get the remainder as 1.

The value of function's when x = -1 is,

⇒ g (- 1) = 1

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;'

The function is,

⇒ g (x) = x³ + 6x² + 12x + 8

Now, Substitute x = - 1 in above function, we get;

⇒ g (x) = x³ + 6x² + 12x + 8

⇒ g (-1) = (-1)³ + 6 (-1)² + 12 (-1) + 8

⇒ g (-1) = - 1 + 6 - 12 + 8

⇒ g (-1) = 1

Thus, The value of function's when x = -1 is,

⇒ g (- 1) = 1

The expression 8x+2 factored using the GCF is 2(4x + 1)

Equations are expressions separated by an equal sign

Given the expression 8x + 2

First we need to find the factors of each terms

8x = 2 * 4 * x

2 = 2 * 1

From bot factors, we can see that 2 is common. Factoring out 2 from the expression will give;

8x + 2 = 2(4x + 1)

Hence the expression 8x+2 factored using the GCF is 2(4x + 1)

Answer:

A. maya is correct

Step-by-step explanation:

Answer:

It is a little hard to see where your steps are for the equation, but x = 4, and I will explain:

Step-by-step explanation:

We know y = -1.5x +4, so we plug that into the equation

6x - 5(-1.5 + 4) = 34

6x +7.5x - 20 = 34    Here we distributed the -5 into the parenthesis.

13.5x -20 = 34

13.5 = 54

x = 4

Hope this helps!

Lin got it wrong when solving the system of equations because;

She made the mistake of leaving 7.5x as negative instead of making it positive after multiplying out the bracket.

6x - 5y = 34   ---(eq 1)

3x +2y = 8  ---(eq 2)

2y = 8 - 3x

divide each term by 2 to get;

y = 4 - 1.5x

This corresponds to what she got and it is correct.

6x - 5(4 - 1.5x) = 34

Multiplying out the bracket gives;

6x - 20 + 7.5x = 34

Let's simplify the left side by adding terms with x to get;

13.5x - 20 = 34

Add 20 to both sides to get;

13.5x = 54

x = 54/13.5

x = 4

Answer:

36/125

Step-by-step explanation:

We have a reflection across the x-axis, then the correct option is:

rx-axis(x, y) → (x, –y)

There are two basic reflections, for a given point (x, y):

A reflection across the x-axis changes the sign of the y-component, so we get (x, -y)

A reflection across the y-axis changes the sign of the x-component, so we get (-x, y)

On the image we can see that the figure ABCD is reflected across the horizontal axis, so we only change the signs of the y-components of each vetex of the figure.

Then the correct option is the last one:

rx-axis(x, y) → (x, –y)

Answer: 18 tickets.

Step-by-step explanation:

If we compute:

1282/65 = 19.723

So we have enough for 19 prices, and 0.723 for the next one.

Then we must find the next multiple of 65, near 1282.

Now, the easier way to solve this will be:

To have enough for 20 prices, Carrie needs to have at least 20 times 65 tickets.

So she needs:

20*65 = 1300 tickets.

And she has 1282 tickets.

Then the number of tickets that she needs is:

1300 - 1282 =  18 tickets.

She needs 18 more tickets to have enough for the 20th prize.

Step-by-step explanation:

We get equation B from equation A by Multiplying /dividing both sides by the same non-zero constant i.e., 4.

A non-zero constant polynomial is written as: p(x) = c, where c is a non-zero real number. This means that for all possible values of x, p(x) = c, i.e. it is never 0. Thus, a non-zero constant polynomial does not have any zeroes.

Given

[tex]\frac{x}{4}+1 =-3[/tex]

Multiply/divide both sides by the same non-zero constant i.e., 4.

⇒ [tex]4\times(\frac{x}{4}+1) =4\times-3[/tex]

⇒ x + 4 = -12

Hence, We get equation B from equation A by Multiplying /dividing both sides by the same non-zero constant i.e., 4.

since im typing it out its neater to seperately do left side expression and right side expression

(a+b)(a+2ab) = a(a+2ab) + b(a+2ab) (expansion of terms)

=a^2 +2a^2b + ab + 2ab^2 (remember order of algebraic terms doesnt matter so for instance ab=ba)

other side

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

=2a^2 -2ab -ab +b^2 (remember -b x -b = b^2, negatives cancel out when they multiply by each other)
