f(x)=-2x+13 for f(-4) Evaluate

Answers

Answer:

f( - 4) = 21

Step-by-step explanation:

[tex]f(x)=-2x+13[/tex]

To find f(-4), substitute the value of x that's - 4 into f(x). That is for every x in f(x) replace it with - 4

We have

[tex]f( - 4) = - 2( - 4) + 13 \\ = 8 + 13 \\ = 21 \: \: \: \: \: \: \: \: [/tex]

We have the final answer as

Answers

Answer:

A 09 units to the left of 5.

10 – 2(3x – 1) > 6x + 10


Pls solve with steps and explain

Answers

Answer:

x < 1/6

Step-by-step explanation:

In the equation 10 – 2(3x – 1) > 6x + 10, start by using the distributive property. Once you've done that, you'd now get 10-6x+2 > 6x+10.

Now, add 10 and 2 togther to get -6x+12 > 6x+10.

Subtract 6x to both sides and subtract 12 to both sides and now you'll get

-12x > -2.

Now, divide each side by -12 to get x < 2/12 or 1/6. Notice how the sign is flipped since you divided by a -.

10-2(3x-1)>6x+10
10-6x+2 > 6x+10
10+2> 12x+10
12> 12x+10
2> 12x
1/6>x

X is less than 1/6

In one study, researchers at a clinic looked at more than 120,000 patients enrolled in 14 international studies in the past 10 years. Among the patients with heart problems, researchers found at least one risk factor in 84.7% of the women and 80.7% of the men. If a woman is selected at random from the women with heart problems, what is the probability she has none of the risk factors? Write your answer as a percentage. % If a man is selected at random from the men with heart problems, what is the probability he has none of the risk factors? Write your answer as a percentage. %

Answers

Answer:

The probability she has none of the risk factors  [tex]P(N) =  15.3 \%[/tex]

The probability he has none of the risk factors [tex]P(M) =  19.3 \%[/tex]  

Step-by-step explanation:

From the question we are told that

    The  number of patients enrolled is  n  =  120,000

    The  number of international  studies is  N  =  14

    The  number of years is  y  =  10 years

    The risk  factor for  women  is  r = 84.7%

     The  risk factor for men is  R =  80.7%

     

Generally the probability that she has none of the risk factors is mathematically represented as

     [tex]P(N) =  100 - r)\%[/tex]

=>    [tex]P(N) =  100 - 84.7)\%[/tex]

=>    [tex]P(N) =  15.3 \%[/tex]  

Generally the probability that he has none of the risk factors is mathematically represented as

          [tex]P(M) =  100 - R)\%[/tex]

=>    [tex]P(M) =  100 -  80.7)\%[/tex]

=>    [tex]P(M) =  19.3 \%[/tex]

Triangle X Y Z is shown. Angle X Z Y is a right angle. The length of Z X is b, the length of Z Y is a, and the length of hypotenuse X Y is c.
Given right triangle XYZ, which correctly describes the locations of the sides in relation to ∠Y?

a is opposite, b is adjacent, c is the hypotenuse
a is the hypotenuse, b is opposite, c is adjacent
a is adjacent, b is the hypotenuse, c is opposite
a is adjacent, b is opposite, c is the hypotenuse

Answers

Answer:

C. A is adjacent, B is opposite, C is the hypotenuse

The locations of the sides in relation to ∠Y are that a is adjacent, b is opposite, and c is the hypotenuse. The correct answer would be an option (D).

What is the right triangle?

A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.

In the right triangle XYZ we have

The legs are represented by sides a and b, whereas the hypotenuse is represented by side c. (the greater side)

Angle Y's adjacent side is side a, while angle X's opposite side is side b.

Side b is the opposing side of angle Y and next to angle X.

The hypotenuse is represented by side c.

Because the angles X and Y are complementary, their total equals 90 degrees.

Therefore, we can conclude that a is adjacent, b is opposite, and c is the hypotenuse.

Hence, the correct answer would be an option (D).
