TSolve the system of equations below by graphing. What is the solution rounded to the nearest tenth? (–1.1, 3.2) (0.2, 2.8) (0.7, –4.2) (2.7, 0.1)

Answers

Answer 1

Answer:

Final answer:

To solve the system of equations by graphing, plot the given points on a coordinate plane and find the intersection point.

Explanation:

To solve the system of equations by graphing, we can plot the given points on a coordinate plane and see where the lines intersect. From the given points, we can see that the lines intersect at approximately (-1.1, 3.2). So, the solution to the system of equations rounded to the nearest tenth is (-1.1, 3.2).

(4x^2+6+7)-(-8x^2-2x+6)

Answers

Answer:

12x^2+2x+7

Step-by-step explanation:

Distribute the Negative Sign:

=4x^2+6+7+−1(−8x^2−2x+6)

=4x^2+6+7+−1(−8x^2)+−1(−2x)+(−1)(6)

=4x^2+6+7+8x^2+2x+−6

Combine Like Terms:

=4x^2+6+7+8x^2+2x+−6

=(4x^2+8x^2)+(2x)+(6+7+−6)

=12x^2+2x+7

Cost of a dozen pens is ₹ 180 and cost of 8 ball pens is ₹ 56. Find the ratio of the cost of a pen to the cost of a ball pen. [1 ½ m]

Answers

Answer:

Ratio of cost of a pen to cost of a ball pen is 15:7

Step-by-step explanation:

Given that:

Cost of dozen pens = ₹180

Unit rate = $(180)/(12)$

Unit rate = ₹ 15 per pen

Cost of 8 ball pens = ₹ 56

Unit rate = $(56)/(8)$

Unit rate = ₹7 per ball pen

Ratio of cost of a pen to cost of a ball pen,

15 : 7

Hence,

Ratio of cost of a pen to cost of a ball pen is 15:7
