Answer:

y=-2x-1

Step-by-step explanation:

First we need to know the slope-intercept equation:

y=mx+b

m: slope

b: y-intercept

First we find the slope:

Slope = (y₂-y₁)/(x₂-x₁)

Use any two x and y values on the table:

Slope = [-5-(-3)]/(2-1) = -2/1 = -2

Now we find the y-intercept:

y=mx+b

y=-2x+b

We plug in a pair of x and y values into the equation:

-3=-2(1)+b

-3=-2+b

b=-1

So the slope-intercept equation is:

y=-2x-1

Answer:

y=-2x+(-1)

Step-by-step explanation:

We first need to take two points from the graph. This will allow us to find the slope. Let us take the coordinates: (2,-5) and (1,-3). In order to find the slope using two coordinates, we need to use the following formula:

y^2/x^2 - y^1/x^1

The 2 and 1 are the two coordinates we picked. It is y^2/x^2 because in order to find the slope, you need to put the coordinates in rise/run form. Rise is the y-axis and run is the x-axis. Plug the numbers into the formula:

-5/2 - -3/1

-5-(-3)= -2

2-1=1

-2/1

This will result in the fraction -2/1 or -2. This is our slope. To find the y-intercept, we need to use the following formula (M is the slope):

y=mx

Plug the slope and one x-coordinate. I am going to use coordinate (1,-3):

-2=-2(1)

Use the y-coordinate from the x-coordinate we used above. The -2 in this equation is the product of -2(1). We will be finding the y-intercept using this formula (B is the y-intercept):

-3=-2+b

b= -1

So, our equation is y=-2x+(-1). Sorry for the really long explanation for I tried to make it easy to understand.

Answer:

x=9

Step-by-step explanation:

2x+7x=81

add same variables

9x=81

divide by 9 to isolate x

x=9

Let's solve your equation step-by-step.

81=2x+7x

Step 1: Simplify both sides of the equation.

81=2x+7x

81=(2x+7x)(Combine Like Terms)

81=9x

81=9x

Step 2: Flip the equation.

9x=81

Step 3: Divide both sides by 9.

[tex] \dfrac{9x}{9} = \dfrac{81}{9} \\ x = 9[/tex]

To solve the two given equations, we do the same steps but in a different order.

Here we have two equations, the first one is:

(x - 1)/4 = 5

To solve this, we start by multiplying both sides by 4, so we et:

x - 1 = 5*4

And now we add 1 in both sides:

x = 5*4 + 1 = 21

The second equation is:

x/4 - 1 = 5

This time the "-1" is not in the numerator.

This time we start by adding 1 in both sides:

x/4 = 5 + 1 = 6

And now we multiply both sides by 4:

x = 4*6 = 24

So,  we do the same steps but in a different order.

Using the given discrete distribution, it is found that the standard deviation is of 1.251 shows.

The distribution is:

[tex]P(X = 0) = 0.095[/tex]

[tex]P(X = 1) = 0.203[/tex]

[tex]P(X = 2) = 0.326[/tex]

[tex]P(X = 3) = 0.187[/tex]

[tex]P(X = 4) = 0.174[/tex]

[tex]P(X = 5) = 0.015[/tex]

Hence, the mean is:

[tex]E(X) = 0.095(0) + 0.203(1) + 0.326(2) + 0.187(3) + 0.174(4) + 0.015(5) = 2.187[/tex]

The standard deviation is:

[tex]\sqrt{V(X)} = \sqrt{0.095(0-2.187)^2+0.203(1-2.187)^2+0.326(2-2.187)^2+0.187(3-2.187)^2+0.174(4-2.187)^2+0.015(5-2.187)^2} = 1.251[/tex]

Hey there mate :)

When a number is multiplied by a fraction equal to 1, the value of the number remains the same.

Using this, we can find the values:-

Image 1 answers :

[tex] \frac{4}{5} \times \frac{4}{4} = \frac{4}{5} [/tex]

When we cancel the same 4 of LHS remaining we get as 4/5. By doing the same method, we can find the remaining answers.

[tex]\frac{2}{3} \times \frac{7}{7} = \frac{2}{3} \\ \\ \frac{5}{6} \times \frac{8}{8} = \frac{5}{6} \\ \\ \frac{3}{4} \times \frac{5}{5} [/tex]

Image 2 answers :

[tex] \frac{2}{3} \times \frac{4}{2} = \frac{4}{3}[/tex]

Here, cancel the common numbers in LHS and write back the remaining uncancelled numbers to get 4/3 in RHS.

Using same method,

[tex] \frac{3}{4} \times \frac{5}{3} = \frac{5}{4} [/tex]

Next, Now in last two questions, we have to do a little differently. Till this much time we did by cancelling the common numbers. So, multiply the numerator and denominator.

[tex] \frac{1}{4} \times \frac{3}{2} \\ = > \frac{1 \times 3}{4 \times 2} \\ = > \frac{3}{8} [/tex]

So, above question's answer is 3/8.

Likewise, using the same method, find the next question :-

[tex] \frac{2}{5} \times \frac{4}{3} \\ = > \frac{2 \times 4}{5 \times 3} \\ = > \frac{8}{15}[/tex]

So, next answer is 8/15.

Answer:

Step-by-step explanation:

Let's simplify all the ratios to find which pairs are equivalent.

Option 1)

This is because neither any fractions can be simplified, nor they are equal. Hence, Option 1 is wrong.

__________________________________________________________

Option 2)

Since both of them are giving the same value, Option 2 is correct.

__________________________________________________________

Option 3)

Since both fractions are not equal after simplifying, Option 3 is incorrect.

__________________________________________________________

Option 4)

Since both fractions are not equal after simplifying, Option 4 is incorrect.

We can conclude that Option 2 is correct because the result was equal to the other.

Answer:

The answer is 18

Step-by-step explanation:

A car uses 30 gallons of gasoline for a trip of 750 miles.

Gallons would be used on a trip of 450 miles.

Now, Gasoline used for one mile

30 ÷ 750 = 0.04

So,

0.04 × 450 = 18

Thus, 18 gallons would be used on a trip of 450 miles.

This means for every point you must go up/down to get your next point you divide it by every point you go right/left.

From one point to the next it goes up 2 (rise) and right 1 (run)

The root of a number is the number which is when multiplied by itself a given number of times gives the result equals to the number which under the root. The product of the given number is d.

Given information-

The product given in the problem is,

[tex]\sqrt[3]{d} \times\sqrt[3]{d} \times\sqrt[3]{d}[/tex]

The root of a number is the number which is when multiplied by itself a given number of times gives the result equals to the number which under the root.

Let the result of above product is [tex]f(d)[/tex]. Thus,

[tex]f(d) =\sqrt[d]{3} \times\sqrt[d]{3} \times\sqrt[d]{3}[/tex]

The power of the root of number can be written as the fraction power of root with putting the number in the denominator.Thus,

[tex]f(d) =d^{\dfrac{1}{3}} \times d^\dfrac{1}{3} } \times d^\dfrac{1}{3}[/tex]

The power of the multiple numbers add up when the base is same. Thus,

[tex]f(d) =d^{(\dfrac{1}{3}+\dfrac{1}{3}+\dfrac{1}{3})}[/tex]

[tex]f(d) =d^{\dfrac{3}{3}[/tex]

[tex]f(d) =d[/tex]

Hence the product of the given number is d.
