Answer:

x = -8

Step-by-step explanation:

slope of y = 1/6 is zero

the negative reciprocal of zero is considered to be 'undefined', which is the slope of x=-8 (or x = 'any number')

Answer:

I think C is best explains

The correct option is B.

The graph of g(x) is obtained by flipping f(x) over the x-axis and compressing vertically by a factor of 2.

Transformation means to change. Hence, a geometric transformation would mean to make some changes in any given geometric shape.

Given are two functions f(x) = 4x² and g(x) = -8x², we need to see the transformation done in the function f(x) to give g(x).

So,

We can see that there is scale factor of 2, because it was 4 in f(x) and in g(x) it became -8 that means the graph have been compressing vertically by 2 units.

Also, the presence of minus sign, this is because the reflection has been done here about x-axis, so it becomes -8x².

According to our study we can say that the graph is reflected over x-axis and compressing vertically by 2 units.

Hence, the correct option is B.

The equation of the function is y = 4x + 5. Find the value of y when

x = 3

x = -2

y = 4x + 5 [Equation]

The value of y when x = 3 , x = -2

y = 4x + 5 [Given equation]

[tex] \therefore [/tex] When x = 3 ,

y = 4 × 3 + 5 [Value of x is 3]

y = 12 + 5

Again, when x = -2 ,

y = 4 × (-2) + 5 [Value of x is -2]

y = -8 + 5

Answer:

18x^2 - 30x

Step-by-step explanation:

Distribution:

You just have to distribute 6x by each term in the parenthesis.

Equation: 6x(3x-5)

(You can also think of it as: 6x * 3x + 6x * -5)

18x^2 - 30x

This is as simplified as can it can be.

(You can’t add terms that have different variables, seeing as the first term has x^2 and the second one only has x).

Danny's speed is given:

Andrew's speed is found from the table.

Since its the direct relationship, we find it using one pair of values:

Danny is faster as 15 mph > 14.5 mph

Speed =Distance/Time

Here speed is equal to slope of box

Danny is faster as his one is 15mph

Answer:

x = - 6, x = 7

Step-by-step explanation:

Begin by equating to zero

x² - x - 42 = 0

Consider the factors of the constant term (- 42) which sum to give the coefficient of the x- term (- 1)

The factors are - 7 and + 6 , since

- 7 × + 6 = - 42 and - 7 + 6 = - 1 , then

(x - 7)(x + 6) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 6 = 0 ⇒ x = - 6

x - 7 = 0 ⇒ x = 7

Answer:

x = Total distance from your home to school = 1,500 meters

Step-by-step explanation:

Let

x = Total distance from your home to school

When you walked 20% of the way to school, you still have 1200 meters more to walk

Walked distance = 20% of x

= 20/100 * x

= 0.2 * x

= 0.2x

Total distance - walked distance = 1200 meters

x - 0.2x = 1200

0.8x = 1200

x = 1200 / 0.8

x = 1,500 meters

x = Total distance from your home to school = 1,500 meters

Answer:

5

Step-by-step explanation:

this can be solved using simultaneous equation

2a + 3b = 19  equation 1

1a + 4b = 17    equation 2

Multiply equation 2 by 2

2a + 8b = 34  equation 3

Subtract equation 1 from 3

5b = 15

b = 3

Substitute for b in equation 1

2a + 3(3) = 19

2a = 9 = 19

2a = 10

a = 5

Answer:

Step-by-step explanation:

2a + 3b = 19 equation 1

1a + 4b = 17 equation 2

Multiply equation 2 by 2

2a + 8b = 34 equation 3

Subtract equation 1 from 3

5b = 15

b = 3

Substitute for b in equation 1

2a + 3(3) = 19

2a = 9 = 19

2a = 10

a = 5

Answer:

13 hours

Step-by-step explanation:

First you have to find the hourly rate at which money is being earned. To do so you divided the money earn ($342) by how many hours it took to earn (18 hours).

Once you do that you're given $19.00 per hour.

Now take the money earned with the unknown time ($247) and divide it by money being made per hour ($19)  and you're given 13 hours

Answer:

13

Step-by-step explanation:

First, you need to find out how much money he is making per hour. To do that, we need to do $342 divided by 18 hours. This gives us 19. We now know that Kevin is making $19 an hour. Next, do $247 divided by $19. This gives us 13. He would need to work 13 hours to make $247.
