Answer:

x = [tex]\frac{37}{12}[/tex]

Step-by-step explanation:

Given k(x) = 6x - [tex]\frac{1}{2}[/tex] and k(x) = 18, the equate the right sides, that is

6x - [tex]\frac{1}{2}[/tex] = 18 ( multiply through by 2 to clear the fraction )

12x - 1 = 36 ( add 1 to both sides )

12x = 37 ( divide both sides by 12 )

x = [tex]\frac{37}{12}[/tex]

Given parameters:

Distance covered by Raina = 7 miles

Time taken = 50 minutes

Unknown:

Distance covered in 75 minutes = ?

To solve this problem, we have to find the speed of Raina during the first 50 minutes.

   Speed is the distance covered with time.

      Speed  = [tex]\frac{distance}{time taken}[/tex]  

   Input the parameters and solve;

     Speed  = [tex]\frac{7 miles }{50 minutes}[/tex]   = 0.14miles/min

Now, to find the distance covered in the second run;

     Distance  = speed x time taken

                      = 0.14miles/min x 75min

                      = 10.5miles

The distance covered in miles is 10.5miles

Answer:

We can use slope intercept form to get the points needed. Y= -7+1/3x The points are (0,-7) and (3,-6)

Step-by-step explanation:

Subtract 2x from the left side and place it over to the right side with the 42. Now we have -6y= 42-2x. From here we divide by -6 and we get y= -7+1/3x. We know that are slope is 1/3 which the one is the rise and the 3 is the run. We also know that our y intercept is -7. We plot the points at (0,-7) and (3,-6)

Answer:

[tex] - 3 \geqslant a[/tex]

Step-by-step explanation:

[tex]6 \geqslant - 6(a + 2)[/tex]

distribute -6 inside the parentheses

[tex]6 \geqslant - 6a - 12[/tex]

add 12 to both sides

[tex]18 \geqslant - 6a[/tex]

divide by -6 to isolate the variable

[tex] - 3 \geqslant a[/tex]

Answer:

-3<=a

Step-by-step explanation:

1. Get the -6 away, so multiply everything by -6.  6*-6 >= -6*-6(a+2)

2. This becomes -1 <= a+2   Since if you multiply or divide anything by a negative number, you have to reverse the inequality sign.

3. Subtract 2 to get a by itself    -1-2 >= a

4. This becomes -3 >= a   which is the right answer.

(Just so you know >=  and <=  means less than or equal to and more than or equal to.)

13.77 times the number of people gives you your answer, so probably C=13.77p

Answer:

Step-by-step explanation:

Let the number be x.

twice the square of the sum of a number and 3 is expressed as;

2(x+3)²

If the expression is equal to 98, then;

2(x+3)² = 98

divide both sides by 2;

2(x+3)²/2 = 98/2

(x+3)² = 49

square root both sides

√(x+3)² = √49

x+3 = ±7

x = ±7-3

x = 7-3 or -7-3

x = 4 or -10

Hence the number is 4 or -10

The number is -4 or 10

Let n represent the unknown number

The following equation can be used to summarise the information given in the question

2 × n² = 98

The first step to take in order to determine the value of n is to divide both sides of the equation by 2

n² = 98/2

n² = 49

The second step is to determine the square root of both sides of the equation

n =√49

n =-7 or +7

The number = - 7 + 3 = - 4 or 7 + 3 = 10

Answer:

b = 3

Step-by-step explanation:

Simplify 4b - 3b + 7 = 10

b + 7 = 10

Subtract 7 from both sides

b = 10 -7

Simplify 10 -7 to 3

b = 3

Answer:

42

Step-by-step explanation:

3 is equal to 42 degrees because when you have two parallel lines that have another line pass through both parallel lines the values of degrees are the same as the opposite side so:

42 = 3

2 = 4

and another way you could find the value of 3 is since there is a perpendicular line going through line p we know that since it is perpendicular that the angle between them is 90 so angle 3 is:

90 - (angle 4) = angle 3

You may use this method if you first solved for angle 4 or angle 2 and we can get angle 2 from:

180 - 42 = 138

we can do this because 42 + angle two should be 180 degrees since they are along line n.

Answer:

candy 7

packs 5

Step-by-step explanation:

Answer:

Option A!

Step-by-step explanation:

Hey there!

To figure out the ratio of candies per packs, we divide 21 (candy) by packs (3) and we get 7. This means that there are 7 candies per pack! So, in 1 pack, there are 7 candies and when there are 35 candies, we divide 35 by 7 and get 5.

So, in one pack there are 7 candies and there are 35 candies in 5 packs.

Option A. Candy: 7 Packs:5

Step-by-step explanation:

The value of f(5) will be "-24".

A function would be an equation that typically contains only non-negative integers (-) powers or even just positive integer (+) multipliers of variables, such as the quadratic function, cubed equation, and so forth, is considered as Polynomial functions.

According to the question,

The given function is:

f(x) = -3x - 9

By substituting "5" in place of "x", we get

→ f(5) = -3(5) - 9

By solving the bracket, we get

         = -15 - 9

         = -24

Thus the above response is correct.

Step-by-step explanation:

The question is incomplete as Micah's workings is not attached. So, there's no way to determine where Micah's error is.

However, I'll solve for the vertex of the given function.

Given

[tex]y = -9.5x^2 + 47.5x + 63[/tex]

Vertex, V is of the form:

[tex]V= (h,k)[/tex]

Where

[tex]h = -\frac{b}{2a}[/tex]

and

[tex]k = f(h)[/tex]

Solving for h:

[tex]y = -9.5x^2 + 47.5x + 63[/tex]

[tex]y = ax^2 + bx + c[/tex]

So:

[tex]a = -9.5[/tex]

[tex]b = 47.5[/tex]

[tex]c = 63[/tex]

[tex]h = -\frac{b}{2a}[/tex]

[tex]h = -\frac{47.5}{2 * -9.5}[/tex]

[tex]h = -\frac{47.5}{-19}[/tex]

[tex]h = \frac{47.5}{19}[/tex]

[tex]h = 2.5[/tex]

Solving for k

[tex]k = f(h)[/tex]

[tex]k = f(2.5)[/tex]

Substitute 2.5 for x in [tex]y = -9.5x^2 + 47.5x + 63[/tex]

[tex]k = -9.5 * 2.5^2 + 47.5* 2.5 + 63[/tex]

[tex]k = -59.375+ 118.75 + 63[/tex]

[tex]k = 122.375[/tex]

Hence:

The vertex is

[tex]V = (2.5,122.375)[/tex]
