Answer:
y = -9/8x +7
Step-by-step explanation:
We know two points on the line so we can find the slope
m = ( y2-y1)/(x2-x1)
m = ( -2 -7)/(8 -0)
= -9/8
We also know the y intercept which is 7
The slope intercept form of the line is
y = mx+b where m is the slope and b is the y intercept
y = -9/8x +7
Answer:
m ∠ AMC = 75°
Step-by-step explanation:
Given:
In Δ ABC, m ∠C=90°
m∠ B =30°
CM is angle bisector
We need to find m ∠AMC
In Δ ABC Sum of all angle is 180° so we get,
Now we know that CM is angle bisector of ∠C
∴
Now in Δ ACM we know that Sum of all angles is 180
Hence m ∠ AMC = 75°
The perimeter of a rectangle is given by the following formula: P = 2W + 2L
To solve this formula for W, the goal is to isolate this variable to one side of the equation such that the width of the rectangle (W) can be solved when given its perimeter (P) and length (L).
P = 2W + 2L
subtract 2L from both sides of the equation
P - 2L = 2W + 2L - 2L
P - 2L = 2W
divide both sides of the equation by 2
(P - 2L)/2 = (2W)/2
(P - 2L)/2 = (2/2)W
(P - 2L)/2 = (1)W
(P - 2L)/2 = W
Thus, given that the perimeter (P) of a rectangle is defined by P = 2W + 2L ,
then its width (W) is given by W = (P - 2L)/2
Speed = distance / time
so ur speed = (3/5) / (3/8) = 3/5 * 8/3 = 8/5 or 1 3/5 miles per hr.
its the first answer choice
Answer:
x=8
Step-by-step explanation:
The side G-F is the same side as side Q-R so 2 times 8 is 16
and 16 - 4 is 12
so x=8
