Answer: The answer is that the office printer prints faster and it can print 30 photos in 15 minutes.

Step-by-step explanation:

I know this ain't wrong for a fact.

Answer:

what?

Step-by-step explanation:

Answer:

ab - a - b + 1 = (a - 1)(b - 1)

Step-by-step explanation:

Let us explain factorization by grouping

In the expression of 4 terms ax + by + bx + ay

Take every two terms have a common factor in a bracket

Take the common factor out of the brackets

Take the bracket as a common factor

Let us do these steps with our question

∵ ab - a - b + 1 is an expression of 4 terms

→ Take ab and a in a bracket, -b and 1 in another bracket

∴ ab - a - b + 1 = (ab - a) + (-b + 1)

→ Take a as a common factor from the 1st bracket and -1 from

   the 2nd bracket

∴ (ab - a) + (-b + 1) = a(b -1) + -1(b - 1)

→ Take the bracket (b - 1) as a common factor

∴ a(b -1) + -1(b - 1) = (b - 1)(a + -1)

∵ (+)(-) = (-)

∴ (b - 1)(a + -1) = (b - 1)(a -1)

→ Change the order of the bracket

∴ (b - 1)(a -1) = (a - 1)(b - 1)

∴ ab - a - b + 1 = (a - 1)(b - 1)

Answer:

11

Step-by-step explanation:

Answer:

11

Step-by-step explanation:

Take -4 and turn it to 0.

-4 + 4 = 0

We added 4 to the number

0 + 7 = 7

We added 7 to the number.

4 + 7 = 11

Answer:

C.

Step-by-step explanation:

3/5 is equal to 15/25 walnuts/raisins

Answer:

No, they are not equivalent

Step-by-step explanation:

Because

120/2 Can not be divided equally into 360/6

Answer:

Yes

Step-by-step explanation:

They are equivalent because if you write the ratio's out, you get 120:2 and 360:6. If you then simplify both, you get 60:1. To simplify these, you need to find a common factor. In 120:2, you can tell that both numbers can be divided by two because they are both even. After dividing, you get 60:1. In 360:6, you can tell that both numbers can be divided by 6 since they both are multiples of 6. After dividing, you get 60:1. Because these to ratio's are equal, they are equivalent.

46, 128/8=16

Answer:

y = 3x+1

Step-by-step explanation:

Well, slope intercept form is y =mx+b, and to find the slope, you have to take two of the examples for y, and divide it by 2 examples of the x, like so:

7- (-5) / 2- (-2) which is 12/4 which is 3, so the slope is 3.

we now can make the first part of the equation:

y = 3x + b

Now we just need "b". To find b, just substitute the x and y values for two values shown on the chart, such as -2 and -5. (They have to be on the same row).

-5 = 3x-2 + b

you get:

-5 = -6+b

which is equal to:

b = 1

So, putting b back in the equation, you get:

y = 3x+1

Step-by-step explanation:

Answer:

3600

Step-by-step explanation:

lcm stands for "lowest common multiple"

the lcm is 3600 when done with the prime factorization process

Answer:

3600

Step-by-step explanation:

Express each number as a product of its prime factors, that is

36 = 2² × 3²

75 = 3 × 5²

80 = [tex]2^{4}[/tex] + 5

Now multiply each factor the greatest number of times it occurs in each of the 3 numbers.

2 → 4 times (that is [tex]2^{4}[/tex] )

3 → twice (3² )

5 → twice (5² )

Thus

LCM = [tex]2^{4}[/tex] × 3² × 5² = 16 × 9 × 25 = 3600

Answer:

5.3

Step-by-step explanation:

because it is going to the left 5.3 so if you absolute value it, it will still be 5.3

Answer: 5x-y+6

Step-by-step explanation:

Answer:

Unit rate = 1.25 inches per yard

Length of fence B on the blueprint = 5 inches

Step-by-step explanation:

We are told that Fence A is 1 1/5 yards long but is 1 1/2 inches long on the blueprint.

This means it's 1.2 yards long but 1.5 inches on the blueprint.

Thus, the unit rate for this blueprint will be; 1.5/1.2 = 1.25 inches per yard

fence B is 4 yards long.

Thus, the corresponding blueprint measurement = 4yards × 1.25 inches/yard = 5 inches.

Answer:

Let x be the number of hours for 1.74 miles

5.3 miles         3.2 hours

1.74 miles        x

When you cross multiply the above numbers you get the equation:

5.3x = 5.568

x = 5.568/5.3

x = 1.05

Therefore it takes 1.05 hours to walk 1.74 miles.

Answer:

− 45 x  +  18 x^2

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

We have the equation [tex]-x-2y=-4[/tex] and we want to find which ordered pair is in the solution [tex]-x-2y\leq -4[/tex]

First, let's convert the inequality to slope-intercept form. So, we have:

[tex]-x-2y\leq-4[/tex]

Add x to both sides:

[tex]-2y\leq x-4[/tex]

Divide both sides by -2. Since we're dividing by a negative, we will flip the sign:

[tex]y\geq- \frac{1}{2}x+2[/tex]

Therefore, our original inequality will be the same as above.

Notice that our y is greater than our equation.

Therefore, the shaded area will lie above our line.

So, any point that falls within the region above our line (in the graph) and on the line is a solution to our inequality.

(-4, 1) is below our line, so it's not a solution.

(-1, 4) is above our line. So, (-1, 4) is our answer.

(-4, -1) is again below our line. So, it's not a solution.

Finally, (4, -1) is also below our line, so it's not a solution.

Therefore, our final solution is B: (-1, 4).

Let's check this. Substitute -1 for x and 4 for y. This yields:

[tex]-(-1)-2(4)\stackrel{?}{\leq}4[/tex]

Multiply:

[tex]1-8\stackrel{?}{\leq}{4}[/tex]

Subtract:

[tex]-7\stackrel{\checkmark}{\leq}4[/tex]

So, (-1, 4) is indeed our solution.

And we're done!

Answer:

C. -1 1/4

Step-by-step explanation:

First, we substitute -5 for x.

[tex]f(-5)=\frac{1}{4} *-5[/tex]

Then, we evaluate.

[tex]f(-5)=\frac{1}{4} *-5=\frac{-5}{4} =-1\frac{1}{4}[/tex]

Answer:

There is no answer for x

Step-by-step explanation:

Answer:

Using trigonometry:

Let's take Tan of 60 degrees:

Tan 60 degrees = Opposite / adjacent

We can see that the opposite side is 3√3 and the adjacent side is x

Tan 60 degrees = 3√3 / x

From the trigonometric table, we know that Tan 60 degrees is √3

√3 = 3√3 / x

x = 3√3 / √3

x = 3

Now, we will take Sin of 60 degrees

Sin 60 degrees = Opposite / Hypotenuse

We can see that the opposite side is 3√3 and the hypotenuse is y

Sin 60 degrees = 3√3 / y

From the trigonometric table, we know that Sin 60 degrees is √3 / 2

√3/2 = 3√3 / y

y = 3√3 / (√3/2)

y = 3√3 * 2/√3

y = 6

Therefore, y = 6 and x = 3

Answer:

im pretty sure it has two real solutions

Step-by-step explanation:

1. simplify the equation given

  (4x - 6)(x + 5) = 15

     4x^2 + 20x - 6x - 30 = 15

        4x^2 + 14x - 45 = 0

2. find the discriminant (b^2 - 4ac); (a = 4, b = 14, c = -45)

  14^2 - (4 x 4 x -45)

     196 - (-720)

        916

  the discriminant is positive, so this equation has 2 real solutions

to find the solutions, factor the bolded equation (if you need help factoring, let me know!)

Answer:

p=228/5

Step-by-step explanation:

2/3p-7=1/4p+12

12(2/3p-7)=12(1/4p+12)

8p-84=3p+144

5p-84=144

5p=228

p=228/5

Check:

2/3(228/5)-7=1/4(228/5)+12

30.4-7=11.4+12

23.4=23.4
