Step-by-step explanation:

Answer:

x = 11.5, y = -5.5.

As an ordered pair this is (11.5, -5.5).

Step-by-step explanation:

2x+4y=1               Multiply this by 3:

3x+5y=7               Multiply this by -2.

6x + 12y = 3

-6x - 10y = -14       Adding these 2 equations:

0 + 2y = -11.

y = -11/2

y = -5.5.

Now plug this into the first equation:

2x + 4(-5.5) = 1

2x = 1 + 22

x = 23/2

x = 11.5.

Answer:

4x-12

Step-by-step explanation:

just distribute the 2 over to the 2x and the -6. That means multiply 2, to everything in the parentheses. Hope that's helpful

The simplified form of the expression [tex](2x - 6)^2[/tex] is [tex]4x^2 - 24x + 36.[/tex]

To simplify the expression[tex](2x - 6)^2[/tex] expand the square.

The square of a binomial follows the formula:

[tex](a - b)^2 = a^2 - 2ab + b^2.[/tex]

The binomial is 2x - 6.

Applying the formula, we have:

[tex](2x - 6)^2 = (2x)^2 - 2(2x)(6) + (-6)^2[/tex]

Simplify each term:

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

[tex]2(2x)(6) = 24x[/tex]

[tex](-6)^2 = 36[/tex]

Substituting these simplified terms back into the expression:

[tex](2x - 6)^2 = 4x^2 - 24x + 36[/tex]

Therefore, the simplified form of [tex](2x - 6)^2[/tex] is [tex]4x^2 - 24x + 36.[/tex]

Answer:

y=2x-2

Step-by-step explanation:

The slope-intercept form is known as y=mx+c

y= the y coordinate

m= the gradient/slope

x= the x coordinate

c= y intercept

The y intercept is when the line crosses the y axis. The graph shows the y intercept is (0,-2). This means our value of c is -2.

Now we must find the value of m. The value of m is the slope of the graph. I usually figure out the slope by doing the change in y / change in x (by counting along how many squares). The change in y is two squares up and the change in x is one square along.

Therefore, the gradient would be 2/1. This equals 2 (so m=2).

Now, we can easily substitute these values into the equation given earlier. Therefore, the equation would be y=2x-2.

n = 3 Year (Approx)

Step-by-step explanation:

Given:

Growth rate (r) = 45% = 0.45

Find:

Number of year for 3 times of population (n)

Computation:

Assume;

Current population = P

So,

New population = 3P

A = p(1+r)ⁿ

3P = P(1+0.45)ⁿ

3 = (1.45)ⁿ

n = 2.96 year

n = 3 Year (Approx)

the area of the square is 1cm^2

Step-by-step explanation:

The computation of the area of the square is given below:

As we know that

Area of the square = side^2

Also in the square four sides are equal

So

= 1cm^2

= 1cm^2

hence, the area of the square is 1cm^2

BC ≈ 98.95 feet

Step-by-step explanation:

From the figure attached,

A shark is swimming 42 feet below sea level at point A and a boat on the water is at point C.

If the angle of depression from the coat to shark is 23°,

tan(23°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

tan(23°) = [tex]\frac{AB}{BC}[/tex]

BC = [tex]\frac{AB}{\text{tan}(23)}[/tex]

BC = [tex]\frac{42}{\text{tan}23}[/tex]

BC = 98.947

BC ≈ 98.95 feet

Answer:

39 miles

Step-by-step explanation:

We know that a cyclist travelled at an average rate of 13 miles per hour for 3 hours and are asked to how far she travelled in miles.

To solve, we need to take into mind that for three hours, the cyclist drove 13 miles per hour.

Meaning that for every hour, 13 miles were driven.

Therefore we need to multiply 13 by 3 to get our answer :

13 miles * 3hrs

39 miles

Answer:

Christ spent a total amount of $ 14.50 on the shirt.

Here we use the linear equation concept to solve the problem.

Since we do not know the amount that Christ has assume that with a variable and form a linear equation using the data given.

Now solve the resultant equation for the value of the variable and find the amount spent by Christ on the shirt as given below

Here we have

Christy spent 2/5 of her money on a shirt.

She has $21.75 left

Let 'x' be the amount that Christy has

From the data,

Christy spent 2/5 of her money on a shirt.  

Amount spent by Christy = 2/5 of x = 2x/5

Remaining amount = x - 2x/5

From the data,

Chrisy is left with $ 21.75

=> x - 2x/5 = 21.75

=> 3x/5 = 21.75

=> 3x = 108.75

=> x = 36.25

Amount the that she spent 2x/5 = 2 (36.25)/5 = 14.50

Therefore,

Christ spent a total amount of $ 14.50 on the shirt.
