The expression would be (5*6)+(5*6)=x
or you could shorten it and do (10*6)=x
10. 8x+4y=4. y=mx+b
-8x. -8x
4y=-8x+4
÷4. ÷4. ÷4
y = -2x +1
slope = -2. y-int= 1
11. slope is changing y over changing x
m = (y2 -y1)/(x2-x1) (0,-1) x1 = 0, y1=-1
(-4-(-1))/(-2-0) (-2,-4) x2 = -2, y2 = -4
(-4 + 1) / (-2)
-3/-2 = 3/2 answer is 3/2
12. b because negative cause it flip in x axis and it become flatter because of the fraction.
13. 2y =8-8x
÷2. ÷2 ÷2
y = 4 - 4x
Answer A
14. B
Answer:
54 yds²
Step-by-step explanation:
Area of 1 side: 3*3=9
Number of sides: 6
6*9=54
Answer:
30.25pi in terms of pi
94.985 In terms of 3.14
Step-by-step explanation:
Okay since the circumference is 11pi we know d = 11.
Meaning r = 5.5
We can solve this in terms of pi or 3.14, for this I will use both.
The formula for an area of a circle is pi*r^2
So,
5.5 * 5.5 = 30.25.
In terms of pi, the answer would be 30.25pi
In terms of 3.14 the answer would be 94.985
:)
