Answer:

√85

Step-by-step explanation:

d = √((x2-x1)2 + (y2-y1)2)

Step by step procedure:

Find the difference between coordinates:

(x2-x1) = (5 - 3) = 2

(y2-y1) = (-1 - 8) = -9

Square the results and sum them up:

(2)2 + (-9)2 = 4 + 81 = 85

Now Find the square root and that's your result:

Exact solution: √85 = √85

Approximate solution: 9.2195

Answer:

11.5

Step-by-step explanation:

1.50 x 5 + 4

Write both sides as powers of 2:

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

[tex]\left(\dfrac18\right)^{x+5}=8^{-x-5}=(2^3)^{-x-5}=2^{-3x-15}[/tex]

Since both powers of 2 are equal, the exponents are equal:

2x = -3x - 15

5x = -15

x = -3

Step-by-step explanation:

Q is at sea level

P is above

R is below

Answer:

The Answer is D

Answer:

Step-by-step explanation:

As per triangle inequality theorem, the third side must be greater than zero but less than 9 + 9 = 18

Possible choices are:

Answer:

9 and 9

Triangle theorem

if x+y <= z, then it cannot be a triangle.

9+9 is 18

so 9+9 <= 18

so the answer is 15, 18 ,4,17.9,1,0.

The slope is positive 5

I hope this is correct and have a great day

The equation 3x + 4y = 8 can be expressed in slope-intercept form as y = (-3/4)x + 2.

To express the equation 3x + 4y = 8 in slope-intercept form, we need to isolate y on one side of the equation. The slope-intercept form is given by y = mx + b, where m represents the slope and b represents the y-intercept.

Let's rearrange the given equation:

3x + 4y = 8

First, subtract 3x from both sides to isolate 4y:

4y = -3x + 8

Next, divide both sides by 4 to obtain y alone:

y = (-3/4)x + 2

Now, we have the equation in slope-intercept form, y = (-3/4)x + 2.

From this form, we can identify the slope, which is -3/4, and the y-intercept, which is 2. The slope represents the rate of change of y with respect to x, and the y-intercept represents the point where the line intersects the y-axis.

Answer:

75

Step-by-step explanation:

If 15 elves finished early and %20 of the elves finished early, then that means 15 elves is %20. 20% can also be written as 1/5, so to get the whole, you just multiply by 5. 5*15=75

Answer:

4.6

Step-by-step explanation:

Use sine rule to find the number that belongs to the box.

Thus:

[tex] \frac{a}{sin(A)} = \frac{b}{sin(B)} [/tex]

a = ?? (the number in the green box)

b = 5

A = 38°

B = 42°

Plug in the values

[tex] \frac{a}{sin(38)} = \frac{5}{sin(42)} [/tex]

Multiply both sides by sin(38)

[tex] \frac{a}{sin(38)} \times sin(38) = \frac{5}{sin(42)} \times sin(38) [/tex]

[tex] a = \frac{5 \times sin(38)}{sin(42)} [/tex]

[tex] a = 4.6 [/tex] (nearest tenth)

Answer: No it is not linear

Step-by-step explanation:

As #of classes increase, free time deceases. Linear equation is when x increase, y also increases. So it is not linear.

An easy way to start a graph is by finding two points for the slope, and then a single point for the intercepts.

The two points I'll use are (0, 80) and (1, 120) (Keep in mind, you can use any two points, they'll all give you the rame ratio).

Use the slope equation:

[tex]b = \frac{(y_2-y_1)}{(x_2-x_1)} \\b=\frac{(120-80)}{(1-0)} \\b=\frac{40}{1} \\b=40[/tex]

Now that we have our slope, we can use one of the points (I'll just use (0, 80)) to create the equation.

[tex]y-y_1=b(x-x_1)\\y-80=40(x-0)\\y-80=40x\\y=40x+80[/tex]

So your final equation is y=40x+80.

* To solve for that second question, just plug in 10 for x and you should get the cost!

Step-by-step explanation:

Vertex's x-coordinate = -b/2a = -4/2 = -2

Vertex's y-coordinate = (-2)² + 4(-2) - 1 = -5

Hence the vertex is (-2, -5).

Answer:

[tex]vertex = (-2,-5)[/tex]

Step-by-step explanation:

[tex]y=x^{2} +4x-1\\\\y=x^2+4x+4-4-1\\\\y=(x+2)^2-5[/tex]

for

[tex]y=(x-h)^2+c\\\\vertex = (h,c)[/tex]

in our equation we have

[tex]h=-2\\\\c=-5[/tex]

so the vertex is

[tex](-2,-5)[/tex]

In standard form. the answer is

2.5 y

Answer:

34 1/3

45 543/1000

Step-by-step explanation:

The third number cannot be converted into fraction form, because it does not have a repeating decimal. The repeating decimal could be a single number or a series of numbers. The number 45.543543543543543... has a repeating decimal that is 0.543. The placement of the last number in the series is in the thousandths place. So, 45.543543543543543543543543... becomes 45 543/1000. For 34/33333..., the number is 34 1/3 in fraction form, because 1/3 is 0.33333.... To check this, divide 1 by 3. After doing so, you would get 0.333...
