if h(x)= 1-7x find the value of h(-7)

Answers

Answer 1
it’s 50
x = -7 so it would be 1-(7x-7)
7 x -7 = -49
1-(-49) = 1 + 49 = 50

Suppose that your boss must choose four employees in your office to attend a conference in Jamaica. Because all 19 of you want to go, he decides that the only fair way is to draw names out of a hat. What is the probability that you, Samuel, Lisa, and Andrew are chosen

Answers

Answer: the probability that I, Samuel Lisa and Andrew are chosen is 0.0003

Step-by-step explanation:

Given that;

Number of 4 employees are to be chosen from 19 of them;

so Number of ways to choose 4 employees from 19 employees = ?

we know that;

c(n,r) = [tex]\left[\begin{array}{ccc}n\\r\end{array}\right][/tex] = n! / ( r!(n-r)!)

so we substitute

c(19,4) = [tex]\left[\begin{array}{ccc}19\\4\end{array}\right][/tex] = 19! / ( 4!( 19-4 )!) = 3876

so the probability that I, Samuel Lisa and Andrew are chosen will be;

⇒ 1 / 3876 = 0.0002579 ≈ 0.0003

the probability that I, Samuel Lisa and Andrew are chosen is 0.0003

One-third of Olivia's age, increased by 12, is equal to twice her age, decreased by 3. How old is Olivia?

Answers

Answer:

Olivia is 9 years old.

Step-by-step explanation:

1/3 of o (Olivia's age) increased by 12, is twice of o minus 3. The equation for this would be 1/3o + 12 = 2o - 3. (The left side could be o/3 as well.)

1/3o + 12 = 2o - 3

Subtract 2o from both sides

-5/3o + 12 = -3

Subtract 12 from both sides

-5/3o = -3 - 12

Subtract 12 from -3 to get -15

-5/3o = -15

Multiply both sides by -3/5, the reciprocal of -5/3

o = -15 (-3/5)

Express -15(-3/5) as a single fraction

o = -15 (-3)/5

Multiply -15 by -3 to get 45

o = 45/5

Divide 45 by 5 to get 9.

o = 9

To make sure this works, substitute 9 for o.

1/3(9) + 12 = 2(9) - 3

3 + 12 = 18 - 3

15 = 15

Both sides match each other, so o equals 9.

Olivia is 9 years old

Let the age of olivia be "x"

One-third of Olivia's age is expressed as 1/3x

If it is increased by 12, the expression becomes 1/3 x  + 12

Twice her age decreased by 3 is expressed as 2x - 3

Equate both expressions and find x

1/3x + 12 = 2x - 3

1/3x - 2x = -3-12

(x-6x)/3 = -15

-5x = -45

x = 9

Hence Olivia is 9 years old

Step-by-step explanation:

1. Subtract 2x2x from both sides. 3y=5x-y-2x

3y=5x−y−2x

2. Simplify  5x-y-2x5x−y−2x  to  3x-y3x−y.

3y=3x-y

3. Add yy to both sides.3y+y=3x

3y+y=3x

4. Simplify  3y+y3y+y  to  4y4y. 4y=3x

4y=3x

5. Divide both sides by 33.\frac{4y}{3}=x34y=x

6. Switch sides.x=\frac{4y}{3}

x= 34y! Hope this helped!! :))

Find the gradient of the line segment between the points (1,-2) and (-2,10).​

Answers

Given:

A line segment is between the points (1,-2) and (-2,10).​

To find:

The gradient of the given line segment.

Solution:

We know that gradient of the given line segment means slope of the line segment.

The line segment between the points (1,-2) and (-2,10).​ So, slope of the line segment is

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\dfrac{10-(-2)}{-2-1}[/tex]

[tex]m=\dfrac{10+2}{-3}[/tex]

[tex]m=\dfrac{12}{-3}[/tex]

[tex]m=-4[/tex]

Therefore, the gradient of the given line segment is -4.
