Answer:

y = 5x + 4

Step-by-step explanation:

y - 4 = 5(x - 0)

That is point-slope form. I'm not sure if you want it in slope intercept form, but slope intercept form of the equation is y = 5x + 4

Answer:

y=5x+4

Answer: 293 Seconds

Step-by-step explanation:

Answer:

293 seconds

Step-by-step explanation:

one minute = 60 seconds

4 x 60 = 240 seconds   -------> use the equation above to multiply per min

240 + 53 = 293 seconds  -------> add the remaining seconds to find total

Answer:

89 employees

Step-by-step explanation:

Uniforms come in packs of 8, and the store plans to purchase 56 packs of uniforms.

This means

1 pack = 8 uniforms

56 packs = x uniforms

Cross Multiply

x = 56 × 8 uniforms

x = 448 uniforms

The plan is to hand out 5 uniforms to every employee one for each day or the week.

Hence, the number of employees that the store can give can uniforms to is calculated as:

5 uniforms = 1 employee

448 uniforms = x employees

Cross Multiply

5x = 448 × 1 employee

x = 448/5

x = 89.6 employees.

Since a person cannot be represented by decimal, the store can give uniforms to 89 employees

Answer:

  (b)  30

Step-by-step explanation:

The standard form of a quadratic is ...

  y = ax^2 +bx +c

For such a function, the axis of symmetry is ...

  x = -b/(2a)

Your quadratic function has a=-5, b=+300, so the axis of symmetry is ...

  x = -300/(2(-5) = 30

The peak of the curve is on the axis of symmetry. So, profit is maximized when 30 items are produced.

_____

Of course, a graphing calculator can display the maximum of the function easily.

Answer:

2.4 miles per hour

Step-by-step explanation:

1/5 of a mile is 0.2 miles. If 0.2 miles is 5 minutes, then 0.04 miles is 1 minute, as you divide 0.2 by 5. 0.04 miles per minute=2.4 miles per hour as you times 0.04 by 60.

Step-by-step explanation:

Answer: To find the median, count the dots from left to right until you find the middle value.

Step-by-step explanation:

Ok so first it's not a dot line it's a dot plot. Second, let's define what a medium is. The medium is the "middle" of a sorted list of numbers. To find the Median, place the numbers in value order and find the middle number. Example: find the Median of {13, 23, 11, 16, 15, 10, 26}. The middle number is 15, so the median is 15. Tip to find the median from a list of value ordered numbers every time cross a number from each side. For example, if you cross 13 from above also cross 26 and if you cross 23 then also cross 10.

Back to your original question of how to find the medium on a dot plot you need to take all the numbers from your dotted line put them in order even if they are repeated and then cross each one on each side from right to left. Also remember if you cross out all the numbers right and left and end up with two numbers left then take them and add them and then divide by 2 and that will be the median.

Answer:

1,73205

Step-by-step explanation:

First, count out the five decimal places, and then look at the sixth place:

[tex]\sqrt{3}[/tex] ≈ 1,73205 | 0807...

The sixth decimal is less than 5, so we round to the smaller side.

Third is 9

Step-by-step explanation:

Answer:

61

Step-by-step explanation:

As we can see the triangles are congruent so

< F = < C ( being corresponding angles of congruent triangle)

< C = 29

Now

<A +<B + <C = 180° { being sum of angles of triangle }

5x + 1 + 90 + 29 = 180°

5x = 180° - 120°

5x = 60°

x = 12°

<A = 5 * 12° + 1 = 61°

Hope it will help :)

Answer:

64

Step-by-step explanation:

We have the function f(x) 7x^2 + 8x + 20 and are asked to solve it.

Since we know that x equals 2. We can substitute 2 for every x in the expression.

7(2)^2 + 8(2) + 20

First do the exponent :

2^2

4

7(4) + 8(2) + 20

Multiply 7(4) and 8(2) :

7(4)

28

8(2)

16

28 + 16 + 20
