how many different ways can you find for 7 coins totaling 95 cents?​

Answer:

a

Step-by-step explanation:

solve for y in one equation

2x + y = -4

y = -4 - 2x

plug y into the other equation

5x + 3y = -6

5x + 3(-4 - 2x) = -6

5x -12 -6x = -6

-x - 12 = -6

-x = 6

x = -6

plug x into the equation to find y

y = -4 - 2x

y = -4 - 2(-6)

y = 8

ordered pair: (-6,8)

Answer:

[tex]p(x) = -0.01x + 15[/tex]

Step-by-step explanation:

Given

Let x represent the number of tickets, and p the charges

[tex](x_1,p_1) = (500,10)[/tex]

A reduction of 50c gives an increment of 50 tickets.

This gives:

[tex](x_2,p_2) = (500+50,10-0,5)[/tex] ---- [tex]50c = \$0.5[/tex]

[tex](x_2,p_2) = (550,9.5)[/tex]

Required

Determine the demand function

First, calculate the slope:

[tex]m = \frac{p_2 - p_1}{x_2 - x_1}[/tex]

[tex]m = \frac{9.5 - 10}{550-500}[/tex]

[tex]m = \frac{-0.5}{50}[/tex]

[tex]m = -0.01[/tex]

So, the equation is:

[tex]p = m(x - x_1) + y_1[/tex]

[tex]p = -0.01(x - 500) +10[/tex]

[tex]p = -0.01x + 5 +10[/tex]

[tex]p = -0.01x + 15[/tex]

Hence, the function is:

[tex]p(x) = -0.01x + 15[/tex]

RULE 1 :ANY SIDE OF THE TRIANGLE MUST BE LESS THAN THE SUM OF THE OTHER TWO SIDES

6< 12+5

5<6+12

12<5+6 (this is wrong number 1)

RULE 2: ANY SIDE MUST BE LESS THAN THE SUBTRACTION OF THE SMALLER SIDE AND THE BIGGER SIDE

6>12-5(wrong number 2)

5>12-6(wrong number 3)

12> 6-5

Answer:

x=4,y=2

Step-by-step explanation:

3x-2y=8 ..........1

2x+y=10...........2

multiply equation 2 by 2 and adding equation 1 and 2 ,we get

3x-2y=8

4x+2y=20

+_________

7x=28

x=28/7=4

:.x=4

again substituting value of x in equation 1 we get

3×4-2y=8

12-8=2y

y=4/2=2

:.y=2

Answer:

J = 6/5

Step-by-step explanation:

8−6j=9j−10

Step 1: Simplify both sides of the equation.

8−6j=9j−10

8+−6j=9j+−10

−6j+8=9j−10

Step 2: Subtract 9j from both sides.

−6j+8−9j=9j−10−9j

−15j+8=−10

Step 3: Subtract 8 from both sides.

−15j+8−8=−10−8

−15j=−18

Step 4: Divide both sides by -15.

−[tex]\frac{-15j}{-15}[/tex] = [tex]\frac{-18}{-15}[/tex]

j= [tex]\frac{6}{5}[/tex]

Answer:

j = 1.2

Step-by-step explanation:

8 - 6j = 9j - 10​

We can subtract 8 from each side

8 - 6j = 9j - 10​ - 8

Simplify

-6j = 9j - 18

Subtract 9j from both sides

-6j - 9j = 9j - 18 - 9j

Simplify

-15j = -18

Divide by -15 from both sides

[tex]\frac{-15j}{-15}=\frac{-18}{-15}[/tex]

Solve

j = 1.2

Answer:

0

Step-by-step explanation:

L Hospital's rule states that as long as u have the form

of infinity / infinity or 0/0 in general you can take its derivative to find the limit.

In this case as X tends to 0, the numerator tends to 0

Denominator will also tends to 0.

We have the 0 / 0 form, which means we can take the derivative for its numerator and denominator which gives

(2x - 2SinxCosx) / 2x | lim x -> 0

= (2x - Sin2x) / 2x | lim x -> 0

Based on this equation, as x tends to 0

both numerator and denominator tends to 0.

So we take its second derivative,

(2 - 2Cos2x) / 2

Now as x -> 0,

we will get (2 - 2)/2 = 0

Answer:

2(19-c)=2(6c+2)+3c  use distributive property

38-2c=12c+4+3c      combine like terms

38-2c=15c+4        add 2c on both sides

38=17c+4        subtract 4 from both sides

34=17c         divide by 17 on both sides

2=c and you get 2=c or c=2

Step-by-step explanation:

if brainiest is earned its Greatly Appreciated

The solution to the given equation is c =2.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

The equation is given in the question, as follows:

2(19 - c) = 2(6c + 2) + 3c

Apply the distributive property

38 - 2c = 12c + 4 + 3c      

Combine like terms in the above equation,

38 - 2c = 15c + 4        

Add 2c on both sides of the equation,

38 = 17c + 4        

Subtract 4 from both sides in the above equation,

34 = 17c        

Divide by 17 on both sides

2 = c or

c = 2

Therefore, the solution to the given equation is c =2.

Answer:

Step-by-step explanation:

Answer:

1, 2, 3, and 6 are factors of 6 while 1, 3, 9, and 27 are factors of 27.  Notice that the product of the outer elements equal what your factoring as well as the inners.

1x6=6, 2x3=6, 1x27=27, and 3x9=27.  Notice the GCF in this case is 3, so factor that out of your initial expression.

Therefore 3(2+9) = 6 +

Answer:

2x^4

Step-by-step explanation:

When multiplying variables with exponents multiply the coefficients (the number before the variable) and add the exponents.

SO to solve you have to find a number that when multiplied by 32 equals 64 and a number when added to 8 gives you 12.

2*32=64

8+4=12

So the answer is 2x^4

To find the slope, you can use the formula: [tex]\frac{rise}{run}[/tex]. Start at where the graph intersects at the y-axis, which is -4. So, it rises up 2 units and goes left 3 units, which makes the slope [tex]\frac{2}{3}[/tex].

To find the y-intercept, you would start at where the graph intersects at the y-axis, which is -4 and this would be the y-intercept.

To find the equation, you can use the formula: y = mx + b. m is slope and b is the y-intercept. Plug the slope and y-intercept you found earlier. Thus, your final answer should be: [tex]y = \frac{2}{3}x-4[/tex]

Answer:300

Step-by-step explanation:

goes up by 75 every two

225+75=300

Answer:

300

Step-by-step explanation:

the value increases by increments of 75

the way i found this out was by doing 150-75 which is 75 and then i did that for the rest of them just to make sure and in order to find the value of n you must add together 225 and 75 to get 300
