Answers

Answer:

- 4

Step-by-step explanation:

Step 1:

g ( x ) = 3x + 8     Function

Step 2:

g ( x ) = 3 ( - 4 ) + 8      Input x

Step 3:

g ( x ) = - 12 + 8    Multiply

Answer:

g ( x ) = - 4     Add

Hope This Helps :)

Answer:

g(-4) = -4

Step-by-step explanation:

So we are given the function g(x) = 3x + 8 and we are asked to find g(-4). To find g(-4), we would have to plug in -4 for x in the equation for g(x).

g(-4) = 3(-4) + 8 = -12 + 8 = -4

So g(-4) = -4.

What is an equation of the line that is parallel to y = 9- 4x and passes through (0, 7)​

Answers

y = -4x + 7

Step-by-step explanation:

Since they are parallel they must have the same gradient which is -4

[tex]y = mx + c[/tex]

m = -4

x = 0

y = 7

7 = -4 × 0 + c

c = 7

D.(6.4)

Help FASTTT‼️‼️‼️‼️

Answers

The answer is

A.(2,2)

The new coordinates of point J' of the quadrilateral J' K’ L’ M’ is option (D) (6,4) is the correct answer.

What is transformation of dilation?

Dilation is a kind of transformation in which an object is resized based on a scale factor. Dilation is the process of enlarging or reducing the size of a geometrical object without changing its shape.

For the given situation,

Quadrilateral JKLM is dilated by a scale factor of 2 with a center of dilation at the origin to form quadrilateral J' K’ L’ M’.

To dilate the figure by a factor of 2, we need to multiply the x and y-value of each point by 2.

Here the coordinates of J is (3,2).

The dilation factor is 2, so multiply both the x and y value by 2.

Thus x value is

[tex]3(2)=6[/tex]

and y value is

[tex]2(2)=4[/tex]

Hence we can conclude that the new coordinates of point J' of the quadrilateral J' K’ L’ M’ is option (D) (6,4) is the correct answer.

b. If an animal is not a golden retriever, then it is not a dog; false

C. If an animal is a dog, then it is a golden retriever; false

If an animal is not a dog, then it is not a golden retriever; true

Answers

Answer:

C. If an animal is a dog, then it is a golden retriever; false

Step-by-step explanation:

Logical reasoning is an important aspect of mathematics.

The conditional statements in the question are represented by the letters p and q. The if-then statement in which the statement p will lead to a conclusion in q is a glaring characteristic of conditional statements. A conditional will be held to be true unless a statement that is true has a false conclusion derived from it.

In the question above, the conditional statement is; If an animal is a dog, then it is a golden retriever. We can clearly see that this conclusion is false.

if u pour all the liquid in a cone into a cylinder with the same height and radius then you will fill half of the cylinder with liquid

Answers

Answer:

No, the liquid will not fill half of the cylinder

Step-by-step explanation:

The volume of a cylinder is 3 times bigger than a cone with equal radius and height

To know this we have to compare the volumes of both solids first.

Let us assume the height and radius of the cone and radius are

6 and 2 mm respectively

so that the volume of a cone is given as

Volume of cone= 1/3 πr^2h

and the volume of cylinder is given as

Volume of cylinder= πr^2h  

1. Volume of cone= 1/3 πr^2h

Volume of cone= 1/3 *3.142*(2)^2(6)

Volume of cone= 75.408/3

2.  Volume of cylinder= πr^2h

Volume of cone= 3.142*(2)^2(6)

Volume of cone= 75.408

From the analysis the volume of a cylinder is three times bigger the volume of a cone with similar radius and height

A candy store owner has chocolate candies worth $2.50 per pound and sour candies worth $0.90 per pound. How much of each kind of candies should she combine to get 60 lb of mixed candies worth $1.70 per pound? (Include units with your numerical answers.)

Answers

Answer:

Weight of chocolate candies = 30lbs

Weight of sour candies = 30lbs

Step-by-step explanation:

We are told in the question that :

Chocolate candies worth $2.50 per pound

Sour candies worth $0.90 per pound. How much of each kind of candies should she combine to get 60 lb of mixed candies worth $1.70 per pound?

Let x represent the number of pounds of chocolate candies

Let 60 - x represent the number of pounds of sour candies

Hence, we have the equation

x × $2.50 + (60 - x) × $0.90 = 60 × $1.70

= 2.5x + 54 - 0.9x = 102

Collect like terms

2.5x - 0.9x = 102 - 54

= 1.6x = 48

x = 48/1.6

x = 30 lbs

x represent the number of pounds of chocolate candies,

60 - x represent the number of pounds of sour candies

= 60 - 30

= 30lbs

Weight of chocolate candies = 30lbs

Weight of sour candies = 30lbs

Therefore, she should combine 30lbs of chocolate candies and 30lbs of sour candies to get 60 lb of mixed candies worth $1.70 per pound.

A Small can for $6.29 and large can for $7.00
B Small can for $4.86 and large can for $6.00
C Small can for $4.00 and large can for $7.00
D Small can for $7.00 and large can for $9.00

Answers

Answer:

the answer is c.

Step-by-step explanation:

4 x 5 + 7 x 7 = 69

4 x 3 + 7 x 9 = 75

Cost is small can for $4.00 and large can for $7.00.

What is the system of equation?

One or many equation having same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.

Let S be  the number of small cans and L be the number of large cans.

According to the question,

One student sold three small cans and nine large cans of peanuts for a total of $75.

That means the equation is ;

3S + 9L = 75      {equation 1}

And similarly for another student;

5S + 7L = 69            {equation 2}

Now we have two system of the equation.

3S + 9L = 75      {equation 1}

5S + 7L = 69            {equation 2}

Using elimination process,

we multiply 5/3 to equation 1,

5S + 15L = 125

And subtract equation 1 to the equation 2,

we get L = 7 and S = 4

Therefore, small can for $4.00 and large can for $7.00

Determine the domain of the function (f of g)(x) where f(x)=1/ x+3, g(x) =2/x.

Answers

Answer:

(-infinity, -2/3)u(-2/3,0)u(0, infinity)

Step-by-step explanation:

since it is asking for f(g(x)) we plug g into x which looks like:

f(2/x)

now we plug that into the f(x) equation for all of the x's because that is what replaced the x so:

1/(2/x)+3

we look at the denominator so we can pull the 2/x+3 out and set it equal to zero, therefore solving for x

this gives us -2/3

and we get the 0 from g(x) 's denominator

that should be correct and hope this helps!

box above, how many l-milligram doses are there in

one 2-decagram container?

A) 0.002

B) 200

C) 2,000

D) 20,000

Answers

Answer:

There are 20,000 milligrams in one 2-decagram container . Thus option D is correct.

Step-by-step explanation:

The given information is one type of medicine in 2 decagram container.

Here, we know ,

      1 decagram = 10 grams

and, 1000 milligrams =1 gram

now -: 2 decagram = 2 × 10grams   {since 1decagarm = 10 grams }

                               = 20 grams .

then ,                   = 20× 1000milligrams {since 1 gram = 1000 milligrams}

                           =20,000 milligrams .

Hence, the correct option is D that is 20,000 milligrams .
