Step-By-Step Explanation:

Answer:

(-3, -5)

Step-by-step explanation:

Adding the equations, we get 2y = -10, and thus y = -5.

Substituting this back into the first equation gives us that x = -3.

So, the point of intersection is (-3, -5).

The 5 friends ordered  16  items of $4 , 5 items of $6 , 3 items of $7 .

Let p and q be two variables and

a₁p+ b₁q=c₁              

a₂p+ b₂q =c₂        

Where a₁, a₂, b₁, b₂, c₁, c₂ are  constants   then  we can solve these simultaneous equations by substitution take value of p from equation (1) and then put it in (2) to get an equation for q only and then solve for q. Put value of q in equation (1) to get value of p.

Let the 5 friends ordered  x number of $4 items , y number of $6 and z number of $7 items

They ordered total a total of 24 items.

Then, x+ y + z = 24      ....(1)

Given that $4  was twice the $6 and $7 items combined

Then, x =2( y+ z )

Put this expression of x in (1),we get

2(y+ z)+ y + z =24

3y + 3z =24

y + z =8   ....(2)

Also given that they split the bill at the end, they each owed $23

Therefore total bill will be 5 times $23 = 5*23 = $ 115

Total money spent on bill = $ 4x+6y+7z

Thus, 4x+6y+7z = 115

Again put  x =2(y+ z) here and get

8(y+ z) +6y+ 7z =115

8y +8z + 6y +7z = 115

14y +15z = 115   ....(3)

Therefore, (2) and (3) is the system of equations we have to solve.

From (2) we get y =8 -z

Put this value of y into (3) and get

14(8-z)+15z =115

112 - 14z +15z =115

z= 115-112 = 3

Then, y = 8-z = 8-3 = 5

x = 2(y+ z)= 2(3+5) =16

Therefore x= 16 , y = 5, z=3  from system of equations generate by (2) and (3)

The 5 friends ordered 16 items of $4 and 5 items of $6 and 3 items of $7.

The probability that a randomly selected person from the survey plays pokemon go who belongs to the Age group 26 - 35 is 0.33.

We have the table for the survey,

                                                   Age 18 - 25         Age 26 - 35        Total

Plays Pokemon Go                            17                         39                  56  

Does not play Pokemon Go              37                         25                  62  

Total                                                    54                         64                  118

From the table,

We have,

The number of people in the age group 18 - 25 who play pokemon go is 17.

The number of people in the age group 18 - 25 who play don't pokemon go is 37.

The number of people in the age group 26 - 35 who play pokemon go is 39.

The number of people in the age group 26 - 35 who don't play pokemon go is 25.

The total number of people participated in the survey are 17 + 39 + 37 + 25 = 118

The total number of people in the Age group 18 - 25 is 54.

The total number of people in the Age group 26 - 35 is 64.

The total number of people that play pokemon go is 56.

The total number of people who do not play pokemon go is 62.

Now,

The probability of choosing a random person from the survey from the age group 26 - 35 who plays pokemon go will be:

= ( no. of people of age group 26 - 35 that play pokemon go) / total no. of people in the survey.

If the number of coins in Lauren's collection is 5 times the number in Michael's collection and  the total number of coins in both collection is 366, then the number of coins in Michael's collection is 61

The number of coins in Michael's collection = x

The number of coins in Lauren's collection is 5 times the number in Michael's collection

Then the number of coins in Lauren's collection = 5x

The total number of coins in both collection = 366

Combine the values and the equation will be

x+5x=366

Add like terms

6x= 366

x=[tex]\frac{366}{6}[/tex]
x=61

Hence, if the number of coins in Lauren's collection is 5 times the number in Michael's collection and  the total number of coins in both collection is 366, then the number of coins in Michael's collection is 61

Answer: 26

Step-by-step explanation: 208/8=26

1. y = 5x + 15.

2. y = total cost

x = number of calendar

m = cost per calendar = slope = 5

b = initial value/y-intercept = 15

3. $1,015.

4. The equation in slope-intercept form is: y = 5x + 15

5. Slope (m) = 5

6. y-intercept (b) = 15; x-intercept = -3.

7. See attachment below for the graph.

Using the information given, we can create an equation in slope-intercept form y = mx + b, where m would be the slope and b would be the y-intercept of the linear equation.

Let,

1. To create an equation that models the situation, substitute m = 5 and b = 15 into y = mx + b:

y = 5x + 15.

2. The variables and numbers in the equation are:

y = total cost

x = number of calendar

m = cost per calendar = slope = 5

b = initial value/y-intercept = 15

3. Substitute x = 200 into y = 5x + 15

y = 5(200) + 15

y = 1,015

Total cost = $1,015.

4. The equation in slope-intercept form is: y = 5x + 15

5. The slope (m) = 5

6. The y-intercept (b) = 15

To find the x-intercept, substitute y = 0 into y = 5x + 15

0 = 5x + 15

-5x = 15

x = 15/-5

x = -3

The x-intercept = -3.

Step-by-step explanation:

Answer:

[tex]g(x) = (x-4)^2\; and \;h(x)= x^2-4 \;are\;\bold{not}\;equivalent[/tex]

Step-by-step explanation:

For two functions g(x) and h(x)  to be equivalent, they must have the same domain and range.

Domain is the set of all values of x(inputs)  that result in a real and defined value for the function

Range is the set of all values of the function that it can take given the values of x in the domain

[tex]g(x)=(x-4)^2=16-8x+x^2\\[/tex]

Can be rewritten as
[tex]g(x) = x^2 -8x + 16[/tex]  The domain of g is unrestricted, g can be any value so the

Domain of g: [tex]-\infty < x < \infty[/tex]
Range of g: Since [tex](x-4)^2[/tex] is always positive including 0, the range of g(x) is g(x) ≥ 0

[tex]h(x) = x^2 - 4[/tex]

Domain of h : [tex]-\infty < x < \infty[/tex] since x can be any value and we will still get a real number as function output

However x² is always zero or a positive number so we have the restriction
x² ≥ 0

Subtract 4 on both sides

x²-4 >= -4

But the above is nothing but the outputs of h(x)

So h(x) >= -4 and can be written as -4 ≤ x ≤ ∞

So we can see that, while the domains of the two functions are the same, their ranges are different

Hence the two functions g(x) and h(x) are not equivalent

Tip
If you have difficulty determining domain and range, take a specific value of x for both functions and check if the function output values are the same. It may not always be easy choosing an appropriate x value depending on the function

For x = 0

g(0) = (0-4)² = (-4)² = 16

h(0) = 0^2 -4 = 0-4 = -4

So we get different output values for the same input value for both functions and therefore they are not equivalent

Hence , 10 liters of a 10% acid solution and 50 liters of a 40% acid solution must be used.

Let the amount of 10 % acid solution be " x " and the amount  40 % acid solution be " y " .

The total volume of the resulting solution is 60 L which can be given by

      x + y = 60       .....(1)

The total acid in the resulting solution is 35 % acid solution which is given by     0.10 x + 0.40 y = 0.35(60)            .....(2)

Multiplying by 100 in equation (2) , we get
