or
Therefore
Answer:
√85
Step-by-step explanation:
for this, you will probably need to draw a graph. Plot the points, and then you will notice that you can draw a triangle with one side being the x-axis ( go on to (-6,0) then drop down unitll you hit the point (-6;-7)
// use the pythagoream theorem to find the length
the distance of the leg on the x-axis is 6 (calculate 0-(-6))
the distance of the leg that is dropping down is -7 (calculate 0-(-7))
then we have 2 legs and need to find the hypotenuse.
Pythagorean theorem a^2 + b^2 = c^2
substitute :
6^2 + 7^2 = c^2
36+49 = 85
c= √85
Step-by-step explanation:
no thanksssssssssssssssssss
The answer should be A. For example, if x = 1, and the ratio between x and y is y is 5 times greater than x, then y would equal 5, which is only true in A.
Or, use the number 5 as an example. If x = 5, and the ratio between x and y is y is 5 times greater than x, then y is 5.
And if you put that into A, y = 5x, it becomes 25 = 5(5)
Then 25 = 25, which is true!
Answer:
-3
Step-by-step explanation:
Bring -2 to the other side and A to the other side
<em>-</em><em>2</em><em> </em><em>Become </em><em>2</em><em> </em><em>because </em><em>of </em><em>flipping</em>
<em>And </em><em>A </em><em>becomes </em><em>-A </em><em>because </em><em>of </em><em>flipping</em>
<em>2</em><em>-</em><em>2</em><em>+</em><em>3</em><em>=</em><em>-A</em>
<em>Flip </em><em>the </em><em>whole </em><em>equation </em><em>to </em><em>avoid </em><em>confusion</em>
<em>-A=</em><em>2</em><em>-</em><em>2</em><em>+</em><em>3</em>
<em>-</em><em>A=</em><em>+</em><em>3</em>
Bring the minus sign to the other side,
<u>A=-3</u>
<u>-</u><u>3</u><u> </u><u>-</u><u>2</u><u> </u><u>+</u><u>3</u><u> </u><u>=</u><u> </u><u>-</u><u> </u><u>2</u>
<u>Which </u><u>make </u><u>the </u><u>statement</u><u> </u><u>correct.</u>
<u>I hope </u><u>this </u><u>explanation</u><u> </u><u>helps, dont hesitate to ask for any question.Mark me as brainliest is appreciated.Tq!!</u>
