A and C is 59 because 1 line is 180 degrees so you add 75 and 46 and you get 121 and then do 180 - 121 and you get 59
Answer:
y= 3x
Step-by-step explanation:
The slope is just read. It is 3. It is the value of m in the general equation.
y = mx + b
y = 3x + b
To find b, use (-1,-3)
x = -1
y = -3 Substitute into the general equation
-3 = 3(-1) + b Simplify the right side
-3 = -3 + b Subtract -3 from both sides
b = 0
Answer: y = 3x
Answer:
Resulting plot in the image attached
Step-by-step explanation:
Start by making a table of (x,y) pairs that satisfy this equation. Notice that two pairs would be enough, but it is always safer to obtain at least three to see them actually "aligned".
We are trying to find values for y when x= 0, 2, and 4 to make our calculations simple:

When x = 0 then:
So we plot the value (0,-3) on the x-y plane.
When x = 2 then:
So we plot the value (2,-2) on the x-y plane.
When x = 0 then:
So we plot the value (4,-1) on the x-y plane.

Answer:
4r^3+8r^2-5r-10
= 4r^2(r+2)-5(r+2) [Factorise out like terms; distributive law of multiplication to check]
=(4r^2-5)(r+2) [Combine expressions]
