Answer:

B) 4x + 8y = 2(2x + 4y)

C) 4x + 8y = 4(x + 2y)

D) 4x + 8y + 12z = 4(x + 2y + 3z)

E) 5x + 10y = 5(x + 2y)

Step-by-step explanation:

We would assume a value for the variables a, b, c, x, y and z.

Let x, a = 1

Let y, b = 2

Let z, c = 3

A) a + b + c = 3abc

When a = 1, b = 2 and c = 3

Substituting into the above equation, we have;

1 + 2 + 3 = 3(1*2*3)

6 ≠ 3(6)

6 ≠ 18 (not equivalent)

B) 4x + 8y = 2(2x + 4y)

When x = 1 and y = 2

Substituting into the above equation, we have;

4(1) + 8(2) = 2(2*1 + 4*2)

4 + 16 = 2(2 + 8)

20 = 2(10)

20 = 20 (equivalent expression)

C) 4x + 8y = 4(x + 2y)

When x = 1 and y = 2

Substituting into the above equation, we have;

4(1) + 8(2) = 4(1 + 2*2)

4 + 16 = 4(1 + 4)

20 = 4(5)

20 = 20 (equivalent expression).

D) 4x + 8y + 12z = 4(x + 2y + 3z)

When x = 1, y = 2 and z = 3

Substituting into the above equation, we have;

4(1) + 8(2) + 12(3) = 4(1 + 2*2 + 3*3)

4 + 16 + 36 = 4(1 + 4 + 9)

56 = 4(14)

56 = 56 (equivalent expression).

E) 5x + 10y = 5(x + 2y)

When x = 1 and y = 2

Substituting into the above equation, we have;

5(1) + 10(2) = 5(1 + 2*2)

5 + 20 = 5(1 + 4)

25 = 5(5)

25 = 25 (equivalent expression).

Answer:

Step-by-step explanation:

Using inequality to solve this question, we say

Let the total number of newspapers sold be x

Let the total number of magazines sold by y

x + y = 68

Suppose 1x = $2 and 1y = $5, then

2x + 5y = $199

Solving both as a simultaneous equation, we get that

2(68 - y) + 5y = $199

136 - 2y + 5y = $199

136 + 3y = $199

3y = 199 - 136

3y = 63

y = 63/3

y = 21

Then solving for x, we have

x + 21 = 68

x = 68 - 21

x = 47

Therefore, a total of 21 magazines were sold that day

Step-by-step explanation:

x- intercept is the x coordinate when y is 0

4x + 7(0) = 6

4x = 6

x = 1.5

(1.5, 0)

y- intercept is when x is 0

4(0) + 7y = 6

7y = 6

y = 6/7

( 0, 6/7)

Answer:

g=4/15 or 0.2667

Step-by-step explanation:

g(x)=sin(6x)+3

g(15)=sin(6times 15)+3

15g=sin(90)+3

15g=1+3=4

g=4/15 or 0.2667

The required value of trigonometric function g(×)=sin(6x)+3 at x =15 is 4.

A function g(×)=sin(6x)+3 is given, value of g(15°) is to determine.

These are the equation that contains trigonometric operators such as sin In algebraic operation.

Here,
The function given is g(×)=sin(6x)+3.
to find g(15°) put x = 15 in the trignometric function in order to get the solution.
⇒  g(×)=sin(6x)+3
⇒   x = 15
⇒  g(15) = sin(6 x15) +3
⇒  g(15) = sin°90 + 3
⇒  g(15) = 1 + 3   (sin°90 = 1)

Thus, the required value of trigonometric function g(×)=sin(6x)+3 at x =15 is 4.

Answer:

2%

Step-by-step explanation:

Probability of rain, P(R) = 0.2

Probability of leak Given that it rains, P(L|R) = 0.1

Probability of leak Given that it does not rain, P(L|R') = 0

According to Baye's Rule:

P(L) = [P(L|R) * P(R)] + [P(L|R') * P(R')]

P(R') = 1 - P(R) = 1 - 0.2 = 0.8

P(L) = [0.1 * 0.2] + [0 * 0.8]

P(L) = 0.02 + 0

P(L) = 0.02

Hence, probability of a roof leak on Thursday is 0.02 = (0.02 * 100%) = 2%

Total Josie spend on the dried fruit in all is $4.65

Two or more expressions with an Equal sign is called as Equation.

Given,

Josie buys a scoop of dried cranberries and a scoop of dried bananas to make trail mix.

The dried cranberries weigh 8.5 ounces and cost $0.30 per ounce

The dried bananas weigh 10.5 ounces and cost $0.20 per ounce.

We need to find how much does Josie spend on the dried fruit in all

The total cost for cranberries weigh is 8.5×0.30

$2.55

The total cost for dried bananas weigh is 10.5×0.20

$2.1

The total Josie spend on the dried fruit in all is $2.55+$2.1

$4.65

Hence,  total Josie spend on the dried fruit in all is $4.65

Answer:

The two lines are coincident (essentially the same line) so every point on the line is a solution. Normally you would say they have infinitely many solutions.

An example of this would be:

y = 2x + 3

2y = 4x + 6

The statement that matches this situation would be D.

Answer:

D. The system of equations does not have only one solution (it has infinitely many) because the lines do not intersect at *only* one point.
