Mathematics
1 answer:
serious [3.7K]4 years ago
4 0

Answer:

(-9, 0)

Step-by-step explanation:

Look at the point in your answer. Its y-coordinate is zero. The x-intercept is where the line intersects the x-axis. At the x-axis, every point has y-coordinate zero. Set y equal to zero and solve for x.

-2x + (1/2)y = 18

-2x + (1/2)(0) = 18

-2x = 18

x = -9

Answer: (-9, 0)

A bicycle has a listed price of 837.95 before tax if the sales tax rate is 7.5% find the total cost of the bicycle with a sales
Andru [333]

Answer:

The total cost of a bicycle after the tax = $900.8

Step-by-step explanation:

Given

  • The cost of a bicycle before tax = 837.95 (let say in $)
  • Sales tax = 7.5% = 0.075

To determine

The total cost of the bicycle with a sales tax include

The tax amount can be calculated by multiplying Sales tax i.e. 0.075 with the cost of bicycle before tax i.e. 837.95.

Thus,

Tax amount = 7.5% × 837.95

                    = 0.075 × 837.95

                    = $62.85

Thus, the tax amount is: $62.85

Total cost after the tax can be calculated by adding the Tax amount and the cost before tax.

Therefore,

The total cost of a bicycle after the tax = $62.85 + $837.95

                                                                 = $900.8

Hence, the total cost of a bicycle after the tax = $900.8

Mr. Yueng graded his students’ math quizzes.
Artyom0805 [142]

For this case we must solve the following equation:

x ^ 3 = 22

If we apply cubic root to both sides of the equation, then we eliminate the exponent on the left side:

\sqrt [3] {x ^ 3} = \sqrt [3] {22}\\x = \sqrt [3] {22}

That is the exact solution of the equation. Its decimal solution is given by:

x = \sqrt [3] {22} = 2.8020

ANswer:

The solution to the equation is x = \sqrt [3] {22} = 2.8020

Solve the system of linear equations using any method 6x+6y=-6, 5x+y=-13
Sergio [31]

Answer:

x=-3

y=2

Step-by-step explanation:

To solve this problem you can use the elimination method:

- Multiply the second equation by -6:

(-6)5x+y=-13\\-30x-6y=78

- Add both equations:

6x+6y=-6\\-30x-6y=78\\-------\\-24x=72\\x=-3

- Substitute the value of x into one of the original equations and solve for y:

6(-3)+6y=-6\\-18+6y=-6\\6y=12\\y=2
