Answer: Down 2, right 3
Step-by-step explanation:
Answer:
y = 1x - 1
Step-by-step explanation:
y = mx + b
m is slope
slope = change in y / change in x = (3 - 2) / (4 - 3) = 1/1 = 1
m = 1 so equation is now y = 1x + b
To find b, substitute any value from the table. Let's use (3,2)
y = 1x + b
2 = 1(3) + b
2 = 3 + b
-1 = b
So equation is y = 1x - 1
Answer: A) -2; (2, -2)
Step-by-step explanation: If x is 2 then only the first two answers have the possibilty of being correct since in the coordinate pair the x coordinate is 2.
Sub in x and solve equation
f(x)=-2 so that is where the point of f is.
Answer:
x = 12
Step-by-step explanation:
We know that the total angle measure of a triangle is 180 degrees, so the sum of all the angles should be 180 degrees.
Therefore, we can add all the angles, set them equal to 180 and solve for x
2x+5 + 6x-5 + 7x = 180
We can combine all the x terms and all the numerical terms on the left side of the equation to get:
(2x+6x+7x) + (5-5) = 180
15x = 180
Then we can divide both sides by 15 to isiolate x
15x = 180
x = 180/15 = 12
