Answer:
x=-32/29
Step-by-step explanation:
3x+4y=36 Equation 1
-5x+3y=35 Equation 2
Multiplying equation 1 with 3 (value before y in equation 2) and equation 2 with 4 (value before y in equation 1) we obtain equations 3 and 4 as follows
9x+12=108 equation 3
-20x+12y=140 equation 4
Subtracting equation 3 from equation 4 we obtain
-29x=32
x=-32/29
To find the value of y, we substitute the value of x into equation 2 as initially given in the equation
-5(-32/29)=35-3y
-5(-32/29)-35=-3y
Answer:
see explanation
Step-by-step explanation:
Using the identities
sin(A + B) = sinAcosB + cosAsinB
cotA = 
, tanA = 
Consider the left side
= 
= 
+ 
= 1 + . 
= 1 + cotA tanB = right side , thus verified
Answer:
Step-by-step explanation:
Slope m is defined as m=(y2-y1)/(x2-x1) in this case
m=(218-155)/(22-15)=63/7=9
y=mx+b
y=9x+b, using point (15,155) we can solve for the y intercept b
155=9(15)+b
155=135+b, b=20 so the line is
y=9x+20
In thirty days there will be
y=9(30)+20=290 coins

The notation for the translation is (x, y) → (x + 2, y + 2)
<h3>How to determine the translation?</h3>
The translations are given as:
The above implies that we add 2 to the x coordinate and 2 to the y coordinate.
So, we have:
(x, y) → (x + 2, y + 2)
Hence, the notation for the translation is (x, y) → (x + 2, y + 2)
