Given system:

Divide the first equation by 2 and rearrange:

We got the same equation with the second one. It means we have two of the same lines overlapping.

This gives us infinitely many solutions.

Answer:

30% decrease

Step-by-step explanation:

We have to divide 39 by 130 and then find the percentage of it. 39/130 is equal to 3/10, and 3/10 is equal to 30%. That means that it was a 30% decrease.

Answer:

35%

Step-by-step explanation:

Step-by-step explanation:

[tex] { ({y}^{2} )}^{4} . \: {( {y}^{3}) }^{2} [/tex]

Since,

[tex] { ({a}^{x} )}^{y} = {a}^{xy} [/tex]

Hence,

[tex] {y}^{2 \times 4} . {y}^{3 \times 2} [/tex]

[tex] = {y}^{8} . {y}^{6} [/tex]

Since,

[tex] {a}^{x} . {a}^{y} = {a}^{x + y} [/tex]

Hence,

[tex] = {y}^{8 + 6} [/tex]

[tex] = {y}^{14} (ans)[/tex]

Step-by-step explanation:

Answer: 143

Step-by-step explanation:

The length and width of the rectangle will be 143 inches and 127 inches, respectively.

Let W be the rectangle's width and L its length.

The perimeter of the rectangle will be defined as the total length of all of its sides. So the rectangle's perimeter will be

Perimeter of the rectangle = 2(L + W) units

The length of a rectangle is 16 inches longer than its width. If the perimeter of the rectangle is 540 inches. Then the equations are given as,

L = 16 + W                ...1

540 = 2(L + W)        ...2

From equations 1 and 2, then we have

540 = 2(16 + W + W)

270 = 16 + 2W

2W = 254

W = 127 inches

Then the length of the rectangle is given as,

L = 16 + 127

L = 143 inches

The length and width of the rectangle will be 143 inches and 127 inches, respectively.

Answer:

2. 70°, 60°, and 50°

Step-by-step explanation:

All interior angles of a triangle MUST EQUAL 180°

1) 60 + 42 + 58 = 160

2) 70 + 60 + 50 = 180

3) 110 + 38 + 42 =  190

4) 41 + 75 + 70 = 186

Answer:

B. The sum of the probabilities must equal one. Each probability must be between zero and one inclusive

Step-by-step explanation:

The discrete probability distribution is a distribution in which the random variable would be considered as countable i.e. non-negative digits also it would be presented in table form

So according to the given situation, the option b is correct as their sum would be equivalent to zero also each probability should be lies between zero and one inclusive

===============================================================

Explanation:

Apply the derivative (see attached image for the steps)

You should get [tex]\frac{dy}{dx} = -\frac{1}{(x+2)^{2}}\\\\[/tex]

The line y = x is really y = 1x+0. We see that it's in the form y = mx+b with m = 1 as the slope. The negative reciprocal of this is m = -1, which is the perpendicular slope. As a rule, any two perpendicular lines always have their slopes multiply to -1 as long as neither line is vertical or horizontal.

So we want the derivative we just found to be set equal to -1, that way we have the x value lead to this derivative slope value.

We want dy/dx = -1

In short, the equation we need to solve is [tex]-\frac{1}{(x+2)^{2}} = -1\\\\[/tex]

Let's solve for x

[tex]-\frac{1}{(x+2)^{2}} = -1\\\\\frac{1}{(x+2)^{2}} = 1\\\\(x+2)^{2} = 1\\\\x+2 = \pm\sqrt{1}\\\\x+2 = \pm1\\\\x+2 = 1 \ \text{ or } \ x+2 = -1\\\\x = -2+1 \ \text{ or } \ x = -2-1\\\\x = -1 \ \text{ or } \ x = -3\\\\[/tex]

The smaller x value is -3 while the larger x value is x = -1.

The next point she plots on the graph is (2,9)

The function is given as:

f(x) = 25(Three-fifths)^x

Rewrite properly as:

f(x) = 25(3/5)^x

The first point has an x value of 1.

So, the next would be x = 2

This gives

f(2) = 25(3/5)^2

Evaluate the product

f(2) = 9

So, we have:

(2, 9)

Hence, the next point she plots on the graph is (2,9)

25 seventh-grade students

Step-by-step explanation:

Sampling

This is a common statistics practice, when we want to study something from a population, we find a sample of this population. This sample has to be representative.

In this question:

Students in the seventh grade prefer to visit the aquarium or the science museum for their end-of-year trip.

So the sample would have to contain only students from the seventh grade. So the correct options are:

10 seventh-grade boys and 10 seventh-grade girls

Answer:

See attachment for graph

Step-by-step explanation:

Given

[tex]2 cans = 10ft\ by\ 12ft[/tex]

Required

Graph the relationship between both parameters

First, calculate the area;

[tex]Area = 10ft * 12ft[/tex]

[tex]Area = 120ft^2[/tex]

This implies that: (2, 120) i.e. 2 cans for 120ft^2.

So we have:

(0,0) and (2,120)

(0,0) implies that: 0 cans for 0 square feet

Calculate the slope:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{120 - 0}{2-0}[/tex]

[tex]m = \frac{120 }{2}[/tex]

[tex]m = 60[/tex]

The equation is:

[tex]y = m(x - x_1) + y_1[/tex]

So, we have:

[tex]y = 60 * (x - 0) + 0[/tex]

[tex]y = 60 * (x )[/tex]

[tex]y = 60 x[/tex]
