Answer:

No.

Step-by-step explanation:

x - y ≤ 0

(5, 2)

5 - 2 ≤ 0

3 ≤ 0 is false, so the answer is no.

Answer: No

The value of the expression 4d ÷ c + 3 is 11.

A mathematical expression is a phrase that has a minimum of two numbers or variables and at least one mathematical operation. Let's examine the writing of expressions.

A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression.

Given:

4d ÷ c + 3

Now, for d= 6 and c= 3

we have

4d ÷ c + 3

= 4(6) / 3 + 3

= 4(2) + 3

= 8+ 3

= 11

Hence, the value of the expression is 11.

Answer:

Can I have the numbers???

Step-by-step explanation:

Answer:

 [tex]M' =(-1,7)[/tex]

[tex]N' =(-1,-4)[/tex]

[tex]O' =(-4,4)[/tex]

[tex]P' =(-4,7)[/tex]

Step-by-step explanation:

Given

[tex]M = (-7, 1)[/tex]

[tex]N = (4, 1)[/tex]

[tex]0 = (-4, 4)[/tex]

[tex]P = (-7, 4)[/tex]

Line: [tex]y = -x[/tex]

Required

The coordinates of M'N'O'P'

The rule for reflection over [tex]y=-x[/tex] is : [tex](x,y) \to (-y,-x)[/tex]

So, we have:

[tex]M = (-7, 1)[/tex]  [tex]\to M' =(-1,7)[/tex]

[tex]N = (4, 1)[/tex] [tex]\to N' =(-1,-4)[/tex]

[tex]0 = (-4, 4)[/tex] [tex]\to O' =(-4,4)[/tex]

[tex]P = (-7, 4)[/tex] [tex]\to P' =(-4,7)[/tex]

So, the points are:

[tex]M' =(-1,7)[/tex]

[tex]N' =(-1,-4)[/tex]

[tex]O' =(-4,4)[/tex]

[tex]P' =(-4,7)[/tex]

Hello!

This problem is about relating parallel and perpendicular lines with a given point.

What we need to know here is that parallel lines will have equal slopes, while perpendicular lines will have opposite and reciprocal slopes.

Using this information, let's look at the first part.

We are asked to find a parallel line to the line [tex]y=6x-6[/tex] that passes through the point [tex](4,-3)[/tex].

Since we know that parallel lines have the same slope and we are given a point, we can solve for the y-intercept after setting up and equation.

[tex]y=6x+b[/tex]

[tex]-3=6(4)+b[/tex]

[tex]b=-27[/tex]

So the line would be [tex]y=6x-27[/tex].

Let's look at the second part, where we are asked to find a perpendicular line that passes through the same point.

We know that perpendicular lines have an opposite reciprocal of a slope, and using that information, we can go through the same process and solve for the equation.

[tex]y=-\frac{1}{6}x+b[/tex]

[tex]-3=-\frac{1}{6}(4)+b[/tex]

[tex]b=-\frac{7}{3}[/tex]

So the line would be [tex]y=-\frac{1}{6}x-\frac{7}{3}[/tex].

Hope this helps!

Answer:

9

Step-by-step explanation:

5x - 27 / - 3 = - 6

5x - 27 = - 6 x ( - 3 )

5x - 27 = 18

5x = 18 + 27

5x = 45

x = 45 / 5

Answer:

x = 1

Step-by-step explanation:

Given the matrix;

[tex]-2\left[\begin{array}{ccc}x&-1\\3&5\end{array}\right] + \left[\begin{array}{ccc}3&8\\-1&6\end{array}\right] = \left[\begin{array}{ccc}x&10\\-7&-4\end{array}\right][/tex]

Converting to equations

From the first row of each matrices

-2x + 3 = x

Collect the like terms

-2x - x = -3

-3x = -3

x = -3/-3

x = 1

Hence the value of x is 1

Answer:

The minimum number of samples required is 487.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.95}{2} = 0.025[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

Standard deviation 4.5 mg/L.

This means that [tex]\sigma = 4.5[/tex]

What is the minimum number of samples required to estimate today's level to within 0.4 mg/L with 95% confidence?

This is n for which M = 0.4. So

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]0.4 = 1.96\frac{4.5}{\sqrt{n}}[/tex]

[tex]0.4\sqrt{n} = 1.96*4.5[/tex]

[tex]\sqrt{n} = \frac{1.96*4.5}{0.4}[/tex]

[tex](\sqrt{n})^2 = (\frac{1.96*4.5}{0.4})^2[/tex]

[tex]n = 486.2[/tex]

Rounding up

The minimum number of samples required is 487.

Answer: 18 + 6a + 6b

Step-by-step explanation:

Answer:

6x - 3 y = 6

6x + 8y = -16

multiply equation 2 by -1

-6y -8y = 16

6x - 3y = 6

-11y =22

y = -2

substitute the value of y in 1

6x - 3(-2) = 6

6x + 6 =6

6x =0

x = 0

(x;y)

[0; -2]

9) 4x + 3y = 19

6x + 3y =33

multiply equation 2 by -1

4x + 3y = 19

-6x - 3y = -33

eliminate one variable by adding the equations

-2x =-14

x = 7

substitute the value of x in the equation

4(7) +3y = 19

28+ 3y = 19

3y =-9

y = -3

(x;y)

[7 ; -3]

10 ) 2x + 6y = 17

2x - 10y = 9

multiply by -1 in equation2

2x +6y = 17

-2x + 10 y = -9

eliminate one variable by adding the equations

16 y = 8

y = 1/2

substitute the value of y in the equation.

2x +6 (1/2) = 17

2x + 3 = 17

2x = 14

x = 7

Answer:

B

Step-by-step explanation:

Substitute the coordinates of the point into the left side of the equation and if the value obtained equals the right side then it is a solution.

A (- 4, 4 )

- 3(- 4) - 4 = 12 - 4 = 8 ≠ 6 ← not a solution

B (- 3, 3 )

- 3(- 3) - 3 = 9 - 3 = 6 ← this is a solution

The result is B

Step-by-step explanation:

Answer:

b = 30 yd is the answer.

Step-by-step explanation:

a = 40 yd

b = ?

c = 50 yd

According to the Pythagoras theorem,

a² + b² = c²

40² + b² = 50²

1600 + b² = 2500

b² = 2500 - 1600

b² = 900

b = 30 yd

∴ b = 30 yd is the length of the missing leg.

Answer:

L = 3 cm

Step-by-step explanation:

let lenght be L

First convert area in cm

1 m = 100 cm

12 m = 1200 cm

Area of rectangle =   width x lenght

1200 cm = 400 cm x L

1200 /400 = L

3 cm = L

Answer:

140 Calories and 4 grams of dietary fiber per 1/3-cup serving.  

Step-by-step explanation:

hi you can find this by first doubling the amounts for a 1/2 cup serving

so then it is equal to a full cup serving.

and then divide those by three,

that way it will be equal to 1/3 cup serving.

so

210*2= 420 (lol)

6*2= 12

now divide these numbers by 3

420/ 3 = 140

12/3= 4

so your answers are

140 Calories and 4 grams of dietary fiber per 1/3-cup serving.

I hope this helps! Good luck!
