Answer:
![\boxed{\text{1. y + 5 = -4(x - 3); \qquad 2. y - 8 = x + 1}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Ctext%7B1.%20y%20%2B%205%20%3D%20-4%28x%20-%203%29%3B%20%5Cqquad%202.%20y%20-%208%20%3D%20x%20%2B%201%7D%7D)
Step-by-step explanation:
Question 1
The point-slope formula for a straight line is
y – y₁ = m(x – x₁)
x₁ = 3; y₁ = -5; m = -4
Substitute the values
![\boxed{\textbf{y + 5 = -4(x - 3)}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Ctextbf%7By%20%2B%205%20%3D%20-4%28x%20-%203%29%7D%7D)
The diagram shows the graph of equation 1 (red) with slope -4 passing through (3,-5).
Question 2
x₁ = -1; y₁ = 8; m = 1
Substitute the values
![\boxed{\textbf{y - 8 = x + 1}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Ctextbf%7By%20-%208%20%3D%20x%20%2B%201%7D%7D)
The diagram shows the graph of equation 2 (green) with slope 1 passing through (-1,8).
Well, 5384 is 5000 bigger than 384. So you would add 20000 (4*5000) to the answer of 4*384, which is 1536.
So 1536+20000=21536
Answer:
Below in bold.
Step-by-step explanation:
c) 3 x (9^2)^3/4 x ((81^3)^5/6
= 3 x 81^3/4 x 81^15/6
= 3 x 81^(3/4 + 15/6)
= 3 x 81^13/4
= 3 x 3^13
= 3^14
= 4,782,969.
f) (5x^-1y^2)^-2 / (25 x^2 y - 1)^2
= 5^-2 x^2y^-4 / 625 x^4y^-2
= 5^-2 x^-2 y^-2 / 5^4
= 5^-6 x^-2y^-2
= 0.000064x^-2y^-2.
It is d 1/3
That I saw the answer for your question
Answer:
x=70
Step-by-step explanation:
sum is angles of a Pentagon=540°
x°+138°+2x°+80°+112°=540°
3x°+330°=540°
3x°=540°-330°
3x°=210°
3x°/3°=210°/3°
x=70
