Because 45 is half of 90, 5x=90. 5 times 18 is 90 so x is 18.

Answer:

9

Step-by-step explanation:

45+90= 135

180-135= 45

180 beacuse angles in a straight line add up to 180°

45 ÷ 5 beacause 5x means 5 × x

so 45 ÷ 5 = 9

Explain how to use a number line to find the opposite of integers 4 units away from-6
ollegr [7]

Answer:

The opposite of integer 4 units away from -6 is 10.

Step-by-step explanation:

We know that the opposite of the opposite of a number, say 2, is the number itself.

That is:

Opposite of 2 is -2.

Then the opposite of -2 is:

- (-2) = 2

Now consider a number line.

The number that is 4 units away from -6 is -10.

  • 4 units away implies moving backwards 4 units from -6.

So, the number is -10.

The opposite of -10 will be:

- (-10) = 10

Thus, the opposite of integer 4 units away from -6 is 10.

Convert the polar equation to rectangular coordinates. (Use variables x and y as needed.)
bija089 [108]
[tex]cos(\theta) = x/\sqrt{x^2+y^2} = x/r, and r = \sqrt{ x^2+y^2} so

r = 3 - x/r ==> r^2 + 3r + x = 0,
[\tex]
r = solutions of quadratic and finally
[tex]
r = \sqrt{ x^2+y^2} = solutions,
[\tex]

you could eventually write y(x)! Not sure you're still looking at this question though! ?:)
