6. Determine the Rate of Change in the graph below.

Answer:

For 1 copy it takes 5 seconds, for 2 copy it takes 7 seconds, and for 3 copy it takes 9 seconds.

For each copy, it takes 2 seconds more.

Step-by-step explanation:

A teacher is making multiple copies of a 1-page homework assignment. The time it takes her in seconds is 2 times the number of copies she makes plus 3. What is the total number of seconds it takes for the teacher to make 1 copy? 2 copies? 3 copies? By how many seconds does the total time increase for each copy?

Let the number of copies represented by x and y is the time taken.

The time It takes her in seconds is 2 times the number of copies she makes plus 3.

So the required equation is [tex]y=2x+3[/tex].

To calculate the time taken for the first copy put x=1 in the above equation.

[tex]y=2(1)+3[/tex]

[tex]y=5[/tex]

To calculate the time taken for the first copy put x=2 in the above equation.

[tex]y=2(2)+3[/tex]

[tex]y=7[/tex]

To calculate the time taken for the first copy put x=3 in the above equation.

[tex]y=2(3)+3[/tex]

[tex]y=9[/tex]

Hence, For each copy, it takes 2 seconds more.

Answer:

[tex]A=15\ cm^2[/tex]

Step-by-step explanation:

Given that,

The height of the cuboid = 6 cm

The volume of the cuboid = 90 cm²

We need to find the area of the shaded face.

The volume of a cuboid is given by the formula as follows :

[tex]V=A\times h[/tex]

A is area of the shaded face

Putting all the values,

[tex]A=\dfrac{V}{h}\\\\A=\dfrac{90}{6}\\\\A=15\ cm^2[/tex]

So, the area of the shaded face is [tex]15\ cm^2[/tex].

Answer:

x = 45.6

Step-by-step explanation:

NOTE: Please double-check my answer.

To find x, I used Sine Law.

[tex]\frac{x + 5}{sin65}[/tex] = [tex]\frac{x}{sin40}[/tex]

(x+5)sin40 = xsin65

xsin40+ 5sin40 = xsin65

xsin40 - xsin65 = -5sin40

x(sin40 - sin65) = -5sin40    (I factored out the "x")

x = [tex]\frac{-5sin40}{sin40 - sin65}[/tex]

x = [tex]\frac{-3.725565802}{0.74511316 - 0.826828679}[/tex]

x = 45.6

Answer:

y=-2x+2

Step-by-step explanation:

Just follow the slope-intercept form formula-

Formula: y= mx+b

Key:

y = y-coordinate

m = slope

x = x-coordinate

b = y-intercept

Answer:

2

Step-by-step explanation:

to find the number of couches in the partially filled truck, divide 119 by 9

119/9 = 13.2222

so 13 cars will contain 9 couches packed fully

number of trucks partially filled = 119 - (13 x 9) = 2

Answer:

123 if your going to the nearest whole number

Step-by-step explanation:

Since

6 : 7 = X : 143

Then we know

6/7 = X/143

Multiplying both sides by 143 cancels on the right

143 × (6/7) = (X/143) × 143

143 × (6/7) = X

Then solving for X

X = 143 × (6/7)

X = 122.57142857143

Therefore

6 : 7 = 122.57142857143 : 143

Step-by-step explanation:

[tex] \tt{4 {x}^{2} + 7x - 3 - (2 {x}^{2} + 3x - 1)}[/tex]

While subtracting , the sign of each and every term of second expression changes.

⤏ [tex] \tt{4 {x}^{2} + 7x - 3 - 2 {x}^{2} - 3x + 1}[/tex]

Combine like terms. Like terms are those which have the same base. Only coefficients of like terms can be added or subtracted.

⤏ [tex] \tt{4 {x}^{2} - 2 {x}^{2} + 7x - 3x - 3 + 1}[/tex]

⤏ [tex] \tt{2 {x}^{2} + 4x - 2}[/tex]

[tex] \red{ \boxed{ \boxed{ \tt{Our \: final \: answer : \boxed{ \underline{ \tt{ \: 2 {x}^{2} + 4x - 2}}}}}}}[/tex]

Answer:

t ≤ − 4

Step-by-step explanation:

Answer: t ≤ -4

Step-by-step explanation:

rearrange the problem 24-(-6*t)≤0  Pull out like factors :24 + 6t  =   6 • (t + 4)

Divide both sides by 6    Subtract  4  from both sides t ≤ -4

Answer:

15.25%

Step-by-step explanation:

total 45+250= 295

so percentage (45/295)×100

= 15.25%

Answer:

The diagonal stripes would require a total of 34 feet of tape.

Step-by-step explanation:

You have six hypotenuses, and you can use the Pythagorean theorem to get their lengths.

The total length of the two big diagonals then is:

2×√(36 + 36)

and the total length of the four small diagonals is

4 ×√(9 + 9)

so the total length is:

2√72 + 4√18

= 12√2 + 12√2

= 24√2

≈ 33.9

Answer:

Yes, they will have enough.

Step-by-step explanation:

1. $499.00 + 7% = $533.93

2. $225 x 2 = $550

3. $550 - $533.93 = $16.07 left to spend

Step-by-step explanation:

[tex] \tt{3x + 8 = 2x - 8}[/tex]

We want to get all the constants on the right hand side of the equation. So , Add 8 on both sides of the equation.

⤏ [tex] \tt{3x + 8 + 8= 2x - 8 + 8}[/tex]

⤏ [tex] \tt{3x + 16 = 2x}[/tex]

Move 2x to left hand side and change it's sign. Similarly , Move 16 to right hand side and change it's sign :

⤏ [tex] \tt{3x - 2x = - 16}[/tex]

Since , 3x and 2x are like terms , they can be added or subtracted. Subtract 2x from 3x :

⤏ [tex] \sf{x = - 16}[/tex]

[tex] \red{ \boxed{ \boxed{ \tt{Our \: final \: answer : \boxed{ \underline{ \tt{x = - 16}}}}}}}[/tex]
