can someone explain to me how to get 338 root 2 as the answer​

Answer:

• No

• Yes

• Yes

• No

Step-by-step explanation:

To determine if the 4 given values of y are solutions to the inequality, start by solving the inequality. Solving an inequality is just like that of an equation, except that the direction of the sign changes when the inequality is divided by a negative number.

-2y +7≤ -5

Subtract 7 on both sides:

-2y≤ -5 -7

-2y≤ -12

Divide by -2 on both sides:

y≥ 6

This means that the solution can be 6 or greater than 6.

-10 and 3 are smaller than 6 and are not a solutions, while 7 and 6 satisfies the inequality and are therefore solutions.

_______

Alternatively, we can also substitute each value of y into the inequality and check if the value is less than or equal to -5.

Here's an example to check if -10 is a solution.

-2y +7≤ -5

When y= -10,

-2y +7

= -2(-10) +7

= 20 +7

= 27

Since 27 is greater than 5, it is not a solution to the inequality.

[tex]y = -\frac{1}{3}x + 5[/tex]

Step-by-step explanation:

To being, slope intercept form is the infamous y = mx + b form. In which, m is equal to the slope and b is equal to the y-intercept. (1) To solve this, begin by finding two points of the line. One easy point to find is when x = 0 as it intersects with the y-axis. Two points are: (0,5) and (-3,6). (2) Next, use the slope formula to solve for the slope. The slope formula is [tex]\frac{y2-y1}{x2-x1}[/tex]. Plug in the y and x values;  [tex]\frac{6-5}{-3-0}[/tex]. Simpliify the fraction; [tex]\frac{1}{-3}[/tex] --> [tex]-\frac{1}{3}[/tex]. Therefore -1/3 is our slope. (3) To solve for b, the y-intercept, set up the slope-intercept equation with the newfound slope (y = -1/3x + b) and plug in a point for the y and x values. Doing this will isolate the b so you can solve for it.

6 = -1/3(-3) + b

6 = 1 + b

-1    -1

5 = b

Therefore the y-intercept (b) is 5. (4) The final step is to combine the information into the slope-intercept form; y = -1/3x + 5. Good luck!

Answer:

The outcomes of his 40 experiments are listed in the table, according to him there were 13 times there were two tails. Now simply multiply that times three considering the amount of expirement was tripled.

13 times 3 = 39

First of all, we need to find the slope. In order to find the slope, we'll use the following formula :

[tex]\boxed{\\\begin{minipage}{2cm}slope \\ $\displaystyle\frac{y2-y1}{x2-x1}$\end{minipage}}[/tex]

[tex]\boxed{\\\begin{minipage}{2cm}$\displaystyle\frac{-31-35}{-6-5}$ \\ \end{minipage}}[/tex]

[tex]\boxed{\\\begin{minipage}{2cm}$\displaystyle\frac{-77}{-11} \\ \end{minipage}}[/tex]

Which simplifies to :

[tex]\text{Slope = 7 }[/tex]

Now that we know the slope, finding the point-slope equation is a piece of cake.

Remember Point-Slope :

[tex]\text{y - y1 = m(x-x1)}[/tex]

We're told to use the first point (5, 35) in our equation, so we'll do just that.

[tex]\LARGE\text{y - 35=7(x-5)}[/tex]

The approximate x-coordinates of the points of intersection of the given curves are 0 & 1.76, and the volume of the solid when rotated about the x-axis is 3.15 cubic units

The equations are given as:

y = ∛2x - x²

y = x²/(x² + 1)

See attachment for the graph of the above curves (equation)

From the attached curve, we have the following points of intersection

(x,y) = (0,0) and (1.76,0.76)

Remove the y coordinates

x = 0 and 1.76

Hence, the approximate x-coordinates of the points of intersection of the given curves are 0 and 1.76

The volume of the solid is calculated using:

V = π(R² - r²)

Where R and r are the outer and the inner radii, respectively.

In this case;

R = ∛2x - x²

r = x²/(x² + 1)

Using a calculator, we have:

V = 3.15

Hence, the volume of the solid when rotated about the x-axis is 3.15 cubic units

Answer:

Step-by-step explanation:

The two given numbers both have the denominator 5,  Thus the quotient quickly reduces:

11 4/5 becomes 59/5 and 3 1/5 becomes 16/5.  Dividing the first expression by the second yields 59/16, which can't be reduced.

However, 59 = 48 + 11, so 59/16 = 48/16 + 11/16, which is approximately 3 1/2 (from either Answer B or Answer C).

The exact answer is 3 11/16; B and C are identical and are closer to 3 11/16 thn 3 or 4.

Any equation that starts with y =7x

Parallel lines have the same gradient.

(No options to choose from)

Hope this helps!

Any Equation start with y = 7x + c is parallel to given equation.

To determine whether or not two lines are parallel, the formula for parallel lines is used. When we have the slopes of two lines that we want to compare, we can use the parallel line formula. The parallel lines' distances never change.

Given Equation

y = 7x + 5

and line k

line k is parallel  to equation y = 7x + 5

for parallel lines

The formula for determining whether two lines are parallel is as follows for any two lines with the equations y = m₁ x + c₁ and y = m₂x + c₂:

where m₁ and m₂ are the slopes of the two lines. m₁ = m₂.

given equation y = 7x + 5,

here m₁ = 7 and c₁ = 5

the line which is parallel to equation should be

y = 7x + c

where m₂ = m₁ = 7 and c₂ = c

Hence equation y = 7x +c is parallel to given equation.
