Answer:

Intersecting lines - One solution

Parallel - No solution

Same lines - Infinite number of solution

Step-by-step explanation:

If the graphs intersect then there is one solution. (Example attached)

If the graphs are parallel(they do not touch) then there is no solution

If the graphs are the same, they will be an infinite number of solutions

stiv31 [10]

ANSWER:

Point in original figure (2, -3)

Point in final figure (-3, -2)

STEP-BY-STEP EXPLANATION:

The first thing is to determine the original point of the figure on the graph, which would be:

$P(2,-3)$

The rule for 270° counterclockwise rotation is as follows:

$(x,y)\rightarrow(y,-x)$

We apply it in this case, and the new point would be:

$P(2,-3)\rightarrow P^{\prime}(-3,-2)$

We represent the result on the graph, as follows

Answer:

1) The answer is in decimal since 82.8 is not a square number and does not have a proper square root. And the nearest square number to it is 81 whose root is 9 and the upcoming square number is 100 whose root is 10. So the root of 82.8 will be decimal and between 9 and 10.

2) a^2 + b^2 = c^2

14^2 + 10^2 = c^2

196 + 100 = c^2

296=c^2

root of 296 is 17.2

So, x=17.2

Here also the answer is in decimal since it is not a square number. The nearest square number to 296 is 289 whose square root is 17 and the next square number after 296 is 324 whose root is 18. So the square root of 296 will be in between 17 and 18.

A triangle has a perimeter of 13x-21 units. One side is 4x+3 units. The other side is 5x-8 units. Write an expression to find th

Zepler [3.9K]

Answer:

4x - 16

Step-by-step explanation:

A triangle is a three sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees

the perimeter of a triangle = sum of the side lengths

let the unknown length be represented with y

13x - 21 = 4x + 3 + 5x - 8 + y

13x- 21 = 9x - 5 + y

Make y the subject of the formula

13x - 21 - 9x + 5 = y

4x - 16 = y

the side length = 4x - 16
