Answer:

Since area =7.7

$area = \frac{22}{7} {(r)}^{2} \\ {(r)}^{2} = 2.45 \\ r = 1.57$

Then the circumference is

$c = 2pi\times r \\ = 2 \times 3.14 \times 1.57 \\ = 9.859$

Answer: е) Step-by-step explanation: we know the coordinates of the points so we can easily determine which function this is To begin with, let's take any two points with an integer coordinates let these be two points with coordinates (1 ; 4) and (0 ; 3) Now let's check $a) \ \displaystyle\bf 4=\sqrt[3]{1-3} \ \ wrong$ and all other options except option e are incorrect because $\displaystyle\ e) \sqrt[3]{1} +3=4 \ \ right$

-5x+7+2x-13<9 Please Explain

olganol [36]

Ok the answer is -5 less than 9 which is true lol

Anyways here’s how I got the answer

-5+7+2x-13 less than 9

Combine like terms in this case it’s -5 and 2, and the other is 7 and -13

-5+2= -3
7-13= -6

Ok now that that’s done here’s the next step

-3x-6 less than 9 solve it

-3x-6 < 9
+6< +6

-3x < 15

Now from there you divide then so
-3x/3 cancels out, and 15/-3 = -5
X=-5

And so -5<9 :) hope this helped!! I will also include a picture of my work (please exult messiness lol)
