Can someone help me with homework

Answer:

the answer will be this

Answer:

Only can print 20 page when it's half page

full page he only can print 10

Step-by-step explanation:

40x=800

800/40 = 20

75x=800

10 page only

Answer (part b):

20 half-page advertisements

Step-by-step explanation:

Michael has $800 and the company charges $40 per half-page advertisements. So you can just do 800/40 becuase you need to divide what is being charged ($40) by what Michael has ($800) and you’ll get 20. That’s okay because he said he can purchase 13 advertisements, but these are half-page advertisement. So it’s really just 10 full-page advertisements.

Answer (part c):

About 10 full-page advertisements

Step-by-step explanation:

Again, Michael has $800 and the company charges $75 per full-page advertisements. So you can just do 800/75 becuase you need to divide what is being charged ($75) by what Michael has ($800) and you’ll get 10.6, but the 6 is repeating. You will have to round down to 10 because if you round up, then he won’t have enough money to buy 11.

Hope this helps and answers your question :)

Answer:

180 días.

Step-by-step explanation:

Resolvemos esta pregunta utilizando el método mínimo común múltiple

Buscamos y enumeramos los múltiplos de cada número hasta encontrar el primer múltiplo común.

Este primer múltiplo común es el mínimo común múltiplo.

Múltiplos de 15:

15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195, 210

Múltiplos de 60:

60, 120, 180, 240, 300

Múltiplos de 90:

90, 180, 270, 360

Por lo tanto,

MCM (15, 60, 90) = 180

Por lo tanto, el número de días que mi pago se concede es de 180 días.

Answer:

[tex]x=-3\\y=8(-3)^2\\y=8(9)\\y=72[/tex]

[tex]x=4\\y=8(4)^2\\y=8(16)\\y=128[/tex]

128-72=56

average rate of change is 56

Step-by-step explanation:

Plz let me know if im right

Answer:

8 is the average rate of change

Step-by-step explanation:

Plugin -3 and 4 in for x.

y = 8(-3)^2

y = 72

y = 8(4)^2

y = 128

128-72/4-(-3) = the average rate of change

56/7=8

Answer:

24 yards

Step-by-step explanation:

From the image, we can see that AB and DE are both adjacent sides of their respective triangles.

While, CE and BC are both opposite sides of their respective triangles

Now, from your side, x is the distance to the island.

So, from ratio of similar triangles, we can find x.

Thus;

8/x = 3/9

Cross multiply to get;

8 × 9 = 3x

3x = 72

x = 72/3

x = 24

Thus, distance from your side to the island is 24 yards

Answer: No

Step-by-step explanation:

I guessed..but it was right

Answer:

No

Step-by-step explanation:

Because 15 is with a different number other then 180, then it isn't linear, or graphable. It won't be a function if you have the same number with different numbers. The input and output won't make sense.

Answer:

Step-by-step explanation:

square root of 770 is 27.748873851

in between would be.... square root of 25= 5

                                        square root of 36= 6

answer is 15

cuz its absolute value

Answer:

x=±15

Step-by-step explanation:

When we have absolute value equations, the first step is always to isolate the absolute value. This has already been done.

We know that a quantity in absolute value can be negative or positive, so in order to solve for it, we take the quantity inside the expression--in this case x--and set it equal to negative OR positive of the term on the right side. In this problem, this step would look like this:

[tex]x=-15[/tex] (the original right-side quantity)

and you would also need to solve for

[tex]x=15[/tex]

So [tex]x[/tex] can be ±15

Answer:

B

Step-by-step explanation:

The system of the equation that has only one solution is; 5x-4y=8 and  3x+2y=8.

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

We have to determine;

Which system of equations has only one solution

As per the question,  a system of linear equations can have one solution if there is only one point that makes every equation in the system true.  It implies that there is one point that can satisfy all of the equations at the same time.

The system of equations has only one solution is;

5x-4y=8

3x+2y=8

from equation 1

5x-4y=8

5x=8+4y

[tex]x=\frac{8+4y}{5}[/tex]

Putting the value of x in equation 2

3x+2y=8

[tex]3(\frac{8+4y}{5})+2y=8[/tex]

[tex](\frac{24+12y}{5})+2y=8[/tex]

24+12y+10y=[tex]5*8[/tex]

24+22y=40

22y=40-24

22y=16

y=[tex]\frac{16}{22}[/tex]

y=[tex]\frac{8}{11}[/tex]

Putting the value of b in equation 1,

3x+2y=8

3x+2[tex]\frac{8}{11}[/tex]=8

3x=8-[tex]\frac{16}{11}[/tex]

3x=[tex]\frac{88-6}{11}[/tex]

[tex]x=\frac{82}{33}[/tex]

Therefore, the system of equation which has exactly one solution are;

5x-4y=8 and  3x+2y=8.

#SPJ6

Step-by-step explanation:

2x+4y=8

3x-4y=12

2x+4y+3x-4y=8+12

cancel +4y and -4y

therefore 2x+3x=20

5x=20

x=20/5

x=4

Sibstituting x=4 in 2x+4y=8

2x+4y=8

2*4+4y=8

8+4y=8

4y=8-8

y=0/4

y=0

x=4

y=0

y-intercept: (0, 1)

Answer:

x = 31.5

Step-by-step explanation:

The triangle on the left has 2 congruent sides and is therefore isosceles.

Thus the 2 base angles are congruent with measure

[tex]\frac{180-54}{2}[/tex] = [tex]\frac{126}{2}[/tex] = 63

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

The triangle on the right is also isosceles with base angles of measure x

63° is an external angle of the triangle on the right, thus

x + x = 63

2x = 63 ( divide both sides by 2 )

x = 31.5

Answer:

Solving [tex]8x+6\leq9x+12[/tex] we get [tex]\mathbf{x\geq -6}[/tex]

Option D is correct information.

Step-by-step explanation:

We need to solve [tex]2(4x+3)\leq 3(3x+4)[/tex]

Multiply the terms:

[tex]2(4x+3)\leq 3(3x+4)\\8x+6\leq9x+12[/tex]

Subtracting 6 from both sides

[tex]8x+6-6\leq9x+12-6\\8x\leq9x+6[/tex]

Subtracting 9x from both sides

[tex]8x-9x\leq 9x+6-9x\\-x\leq 6[/tex]

Divide both sides by -1 and reversing the inequality

[tex]x\geq -6[/tex]

So, solving [tex]8x+6\leq9x+12[/tex] we get [tex]\mathbf{x\geq -6}[/tex]

Option D is correct information.

Step-by-step explanation:

27 * x^3 = 6561x-5 , 49x + 1 = 117649x-2

Answer:

To solve the first inequality, you need to subtract 6 from both sides of the inequality, to obtain 4n≤12. This can then be cancelled down to n≤3 by dividing both sides by 4. To solve the second inequality, we first need to eliminate the fraction by multiplying both sides of the inequality by the denominator, obtaining 5n>n^2+4. Since this inequality involves a quadratic expression, we need to convert it into the form of an^2+bn+c<0 before attempting to solve it. In this case, we subtract 5n from both sides of the inequality to obtain n^2-5n+4<0. The next step is to factorise this inequality. To factorise we must find two numbers that can be added to obtain -5 and that can be multiplied to obtain 4. Quick mental mathematics will tell you that these two numbers are -4 and -1 (for inequalities that are more difficult to factorise mentally, you can just use the quadratic equation that can be found in your data booklet) so we can write the inequality as (n-4)(n-1)<0. For inequalities where the co-efficient of n^2 is positive and the the inequality is <0, the range of n must be between the two values of n whereby the factorised expresion equals zero, which are n=1 and n=4. Therefore, the solution is 1<n<4 and we can check this by substituting in n=3, which satisfies the inequality since (3-4)(3-1)=-2<0. Since n is an integer, the expressions n≤3 and n<4 are the same. Therefore, we can write the final answer as either 1<n<4, or n>1 and n≤3.
