Answer:

136

Step-by-step explanation:

4 times 32 = 128

32/4=8

128+8=136

Answer:

135

Step-by-step explanation:

1. divide 32 by 60 to get how many copies per second

[tex]32/60 = 0.533[/tex]

2. convert 4min and 15 sec to seconds

it is 255 seconds

3. Multiply copies per second by number of seconds

[tex]0.533(255) = 135.91[/tex]

4. Round down to whole number because you can't copy part of a paper

y = 4 - ax / 6

ax + 6y = 24

ax - ax + 6y = 24 -ax

6y / 6 = 24 / 6 - ax / 6

y = 4 - ax / 6

Answer:

515.

Step-by-step explanation:

40 x 12 = 480

480 + 35 =515

Answer:

The answer would be $515

Step-by-step explanation:

40x+35=t

40(12)+35=t

40 times 12 = 480

480 + 35 =515

=================================================

Explanation:

Multiply the two values to get 4*15 = 60

Then divide by the GCF 1 to get 60/1 = 60. The GCF being 1 means the result hasn't changed.

------

Another example would be: "Find the LCM of 6 and 8". We would first do 6*8 = 48, then divide by the GCF 2 to get 48/2 = 24. The LCM of 6 and 8 is 24.

Answer:

9

Step-by-step explanation:

two negatives make a positve

Answer:

-9

Step-by-step explanation:

Whenever you are given an expression, first look at it. Since there are two negative signs in the equation, they cancel out, leaving a nine. The opposite value most likely means that the sign is the opposite, so you end up with -9 as the value.

Answer: −1−3k

Step-by-step explanation:

Distribute:

(−3+4k)−1(−2+7k)

(-3+4k)+{2-7k}

Eliminate redundant parentheses:

(−3+4k)+2−7k

-3+4k+2-7k

Add the numbers:

−3+4k+2−7k

−1+4k−7k

Add the same term to both sides of the equation:

−1+4k−7k

−1−3k

Answer:

Pattern

Answer:

The graph of linear inequalities include a dashed line if they are greater than or less than but not equal to. Linear equations, on the other hand, include a solid line in every situation. Moreover, linear inequalities include shaded regions whereas linear equations do not.

Step-by-step explanation:

Answer:

x=-3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−21+6x=3(3x−5)−x

−21+6x=(3)(3x)+(3)(−5)+−x(Distribute)

−21+6x=9x+−15+−x

6x−21=(9x+−x)+(−15)(Combine Like Terms)

6x−21=8x+−15

6x−21=8x−15

Step 2: Subtract 8x from both sides.

6x−21−8x=8x−15−8x

−2x−21=−15

Step 3: Add 21 to both sides.

−2x−21+21=−15+21

−2x=6

Step 4: Divide both sides by -2.

−2x

−2

ANSWER

Answer:

Ur answer should be 2.

Answer:

Step-by-step explanation:

Terms with same variables are like terms

1) 10x + 3y + 5x

Here, 10x and 5x are like terms. so add them

10x + 5x + 3y = 15x +3y

2)2x + 7y +4x + 6x = 2x + 4x + 6x + 7y = 12x + 7y

3)9y+ 3y +5x = 12y +5x

4)2y +7y +4y +6y = 19y

5)8x + y - 2x = 8x  -2x + y = 6x + y

6) x + 7y -4y +9x = x +9x  + 7y - 4y    = 10x + 3y

8) 5y +5y +5y +5x = 15y + 5x

Yes

Step-by-step explanation:

A function is when there is no two of the same domain.

The Domain is the first coordinate which is x.

Hope This Helps :)

Answer:

No

Step-by-step explanation:

No, this is not a function beacuse - 4 and 8 both have the same image 10 and a function is a relation in which every element has one image but this condition doesn't satisfy the definition. So, it is not a function.

Answer:

Function is a reflection and dilation of function f.

Step-by-step explanation:

A reflection gives the mirror image of function.

A function can be reflected about an axis by multiplying by -1.

To reflect function about the x-axis, multiply f(x) by -1 to get -f(x).

The correct option is: B. Function h is a reflection and a dilation of function f.

-----------------------

The functions are:

[tex]f(x) = 2^x[/tex]

[tex]g(x) = -3 \times 2^x[/tex]

It can be seed that g is f multiplied by -3.

In the image at the end of this question, it can be seen that the g, the blue graph, is a reflected and dilated version of f, the red graph.

Thus, the correct answer is:

B. Function h is a reflection and a dilation of function f.

Answer:

C. Two distinct lines are parallel if they are in the same plane and never intersect each other.

Step-by-step explanation:

Parallel lines are best defined as 2 different lines that are in the same plane and will never intersect each other at any point in the graph.

They are always the same distance apart and will never touch.

So, C is correct

Answer:

C

Step-by-step explanation:

The very definition of parallel lines is that they have the same slope, if they have the same slope, they will never meet.

and is it right

Answer/Step-by-step explanation:

The equation, [tex] \frac{20}{x} = -5 [/tex] has one solution, x.

The value of x that will make the equation true, that is the number we can substitute for x into the equation that will make what we have on our left side equal to what we have on our right side is -4.

Substitute -4 for x in the equation and simplify:

[tex] \frac{20}{-4} = -5 [/tex].

Simplifying the equation:

[tex] -5 = -5 [/tex] (this is true).

A value of x that can make the equation false is 4.

Thus, replace x with 4, then simplify.

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

[tex] \frac{20}{4} = -5 [/tex]

[tex] 5 = -5 [/tex] (false. 5 ≠ -5)

Answer:

f (x) = a(x - h)2 + k, where (h, k) is the vertex of the parabola. ... When written in "vertex form": • (h, k) is the vertex of the parabola, and x = h is the axis of symmetry.

Answer:

y =0.25(x-4 )^{2}-1

Step-by-step explanation:

The formula of vertex form is as follows:

Y = a(x-h)^2+k

h = the x value for the vertex (in this case it is 4)

k = the y value for the vertex (in this case it is -1)

If you input these into the equation you are left with:

Y = a(x-4)^2-1

To find 'a' I just entered this equation into the Desmos calculator and messed around with the value until the y-intercept was (8,3)
