Answer:
y=-1/6x-13/3
Step-by-step explanation:
first we find the slope
y1-y2/x1-x2
-3+5/-8+4
1/-6
now we find y intersept
-3=-1/6(-8)+b
-3=8/6+b
-13/3=b
you plug it in y = mx+b
y=-1/6x-13/3
The correct answers are B, D and E
Explanation:
The best way to find if each of the statmenet is true or false is to find the percentage in each case. To do this, follow this general formula: Total number / 100 (100 representes the total) x specific percentage. Now, let's apply this formula in each statement
A)
30 ÷ 100 = 0.3 x 15 = 4.5 (This statement is false)
B)
80 ÷ 100 = 0.8 x 25 = 20 (This statement is true)
C)
50 ÷ 100 = 0.5 x 30 = 15 (This statment is false)
D)
60 ÷ 100 = 0.6 x 30 = 18 (This statement is true)
E)
20 ÷ 100 = 0.2 x 40 = 8 (This statement is true)

Step-by-step explanation:
The formula for finding the surface area of a cone is:
![A=\pi r(r+\sqrt{h^{2}+r^{2}})](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%28r%2B%5Csqrt%7Bh%5E%7B2%7D%2Br%5E%7B2%7D%7D%29)
Our values are:
r = 8
h = 7
π = 3.14
Let's plug the values into the formula
![A=\pi 8(8+\sqrt{7^{2}+8^{2}})](https://tex.z-dn.net/?f=A%3D%5Cpi%208%288%2B%5Csqrt%7B7%5E%7B2%7D%2B8%5E%7B2%7D%7D%29)
![A=\pi 8(8+\sqrt{49+64})](https://tex.z-dn.net/?f=A%3D%5Cpi%208%288%2B%5Csqrt%7B49%2B64%7D%29)
![A=\pi 8(8+\sqrt{113})](https://tex.z-dn.net/?f=A%3D%5Cpi%208%288%2B%5Csqrt%7B113%7D%29)
![A=\pi 8(8+10.63)](https://tex.z-dn.net/?f=A%3D%5Cpi%208%288%2B10.63%29)
![A=\pi 8(18.63)](https://tex.z-dn.net/?f=A%3D%5Cpi%208%2818.63%29)
![A= (3.14)(8)(18.63)](https://tex.z-dn.net/?f=A%3D%20%283.14%29%288%29%2818.63%29)
![A= (25.12)(18.63)](https://tex.z-dn.net/?f=A%3D%20%2825.12%29%2818.63%29)

Answer:
x = 29, C
Explanation: We are given that total angle is 90°, or a right angle. This means that the two complementary angles must equal 90° together.
Create the equation:
2x - 4 + x + 7 = 90
Solve algebraically:
3x + 3 = 90
3x + 3 - 3 = 90 - 3
3x = 87
3x / 3 = 87 / 3
x = 29 or C
