Answer:

-3, 25, 53

Step-by-step explanation:

f(x) = 4x + 9

f(-3) = 4(-3) + 9

f(-3) = -12 + 9

f(-3) = -3

f(4) = 4(4) + 9

f(4) = 16 + 9

f(4) = 25

f(11) = 4(11) + 9

f(11) = 44 + 9

f(11) = 53

Answer:

-3, 25, 53.

Answer:

  g(4a) = 8a^2 -20a +3.5

Step-by-step explanation:

Put 4a where x is and simplify.

  g(x) = 0.5x^2 -5x +3.5

  g(4a) = 0.5(4a)^2 -5(4a) +3.5

     = 0.5(16a^2) -20a +3.5

  g(4a) = 8a^2 -20a +3.5

Answer:

210 students run track and 98 students play baseball

Step-by-step explanation:

For every 15 students who run track there are 7 students who play baseball

There are 112 more students who run track than play baseball

Let y represent the various groups of students

15 × y= 15y

7 × y= 7y

15y - 7y = 112

8y = 112

Divide both side by the coefficient of y which is 8

8y/8 = 112/8

y= 14

Therefore the number of students that run track is

= 15 × 14

= 210

The number of student that play baseball is

= 7 × 14

= 98

Hence 210 students run track and 98 students play baseball

Answer:

It costs $795

Step-by-step explanation:

$30 more than one half so you have to subtract 30 from 295 then that's 265 which is 1/3 of the acual price. So then you have to multiply 265 by 3 then you get $795.

Answer:

z = -3

Step-by-step explanation:

Simplifying

3z + -3 = 2z + -6

Reorder the terms:

-3 + 3z = 2z + -6

Reorder the terms:

-3 + 3z = -6 + 2z

Solving

-3 + 3z = -6 + 2z

Solving for variable 'z'.

Move all terms containing z to the left, all other terms to the right.

Add '-2z' to each side of the equation.

-3 + 3z + -2z = -6 + 2z + -2z

Combine like terms: 3z + -2z = 1z

-3 + 1z = -6 + 2z + -2z

Combine like terms: 2z + -2z = 0

-3 + 1z = -6 + 0

-3 + 1z = -6

Add '3' to each side of the equation.

-3 + 3 + 1z = -6 + 3

Combine like terms: -3 + 3 = 0

0 + 1z = -6 + 3

1z = -6 + 3

Combine like terms: -6 + 3 = -3

1z = -3

Divide each side by '1'.

z = -3

Simplifying

z = -3

Answer:

=3z+3=2z+6

=3z-2z=6-3

=z=3

Answer:

4 degrees farenheight

Step-by-step explanation:

Answer:

4 degrees

Step-by-step explanation:

7am to 11am is 4 hours.

So now multiply 4 hours*4* F = 16

So the temperature decreased 16 degrees.

20-16=4

It was 4 degrees at 11 am.

answer: 68

work:

all you basically do is just divide 272 by 4

If Ralph drove 272 miles in 4 hours then 68 miles per hour is the average speed

A division is a process of splitting a specific amount into equal parts.

Given that Ralph drove 272 miles in 4 hours

We need to find his average speed

The speed of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time

Speed=Distance/ Time

Average speed=272/4

=68 miles per hour

Hence, if Ralph drove 272 miles in 4 hours then 68 miles per hour is the average speed

The dimension of cube is 4 cm

A cube is a three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each [tex]vertex[/tex].

The formula of volume of the cube is given by: Volume = a3, where a is the length of its sides or edges.

Given:

volume of cube= 64 cm³

Now, Volume of cube = 64

a*a*a= 64

a³ = 64

a= ∛64

a=4 cm

hence, the edges of cube is 4 cm.

Answer:

1. A, 2 meters per second

2. F, 15

Answer:

c) 2

Step-by-step explanation:

here you can use cross multiplication. that's where you turn the fraction into an equation. ( there's videos about it, I'm not very good at explaining )

so you can turn

[tex]\frac{5}{x} = \frac{15}{x + 20}[/tex]

into

5(x + 20) = 15x

5x + 100 = 15x

subtract 5x from both sides

100 = 10x

x = 10.

the value of x/5 would be 2, since 10/5 is 2.

Since x/5 is the reciprocal of 5/x, we know that we can flip the fraction on the right hand side will be flipped.

Thus, x/5 = (x + 20)/15

Now we cross multiply, 15x = 5(x + 20)

Simplify: 15x = 5x + 100

Subtract 5x from each side: 10x = 100

Divide 10: x = 10

Now plug 10 back into the right hand side: (10 + 20)/15

So, the answer is 2.

Explanation:

when you reflect anything over the line y = x, that is the same thing as taking the inverse(you swap the x and y values)

Answer: Range = (-∞, 3) U (3, ∞)

Step-by-step explanation:

The range is the set of all y-values in a function. The easiest and most straightforward way to find the range is to graph the function and find asymptotes, or locations on the graph where the function lacks y-values.

You can plug in a few points to the equation, as shown in this table below.

After you have your points, you can draw your function following the points, as shown in the next image. Notice the line at y = 3, where the function does not cross. Although it will get infinitely close to the line, the function will never meet or cross this point at any x-value. This is what is known as a "horizontal asymptote", and is not included in the range of the function.

We can represent this asymptote in a range, which is a representation of all possible y-values in the function. The possible y-values for this function start at negative infinity and end at infinity, but do not exist at y = 3, so we represent this through this mathematical expression:

Range = (-∞, 3) U (3, ∞)

The right equation of the red line will be f(x)=y-4 if the equation of the black line is f(x)=y

The equation is like a relationship between variables.

A variable is anything which have a value.

If we see the points of red line and the lack line we can see the value of x in black line is 4 greater than red line so the equation will be

f(x)=y-4 for the red line for the given equation of the lack line which is f(x)=y
