Graph 60 to 40 try this method I did this question but different questions
Answer: 3
Step-by-step explanation:
Set them equal because they are the same so 15x+5=16x+2 so x+2=5 so x=3
<h3>Answers:</h3>
- Part A) Solution is (-3,-3)
- Part B) Two solutions are (0,0) and (2,2)
- Part C) Solution is x = -6
=========================================================
Explanation:
Part A
Ignore the g(x) curve. We're looking for the intersection of the p(x) and f(x) curves. The two cross at (-3,-3) which is the solution to the system of these two equations. This point is on both p(x) and f(x) simultaneously. That means the coordinates of the point satisfy both p(x) and f(x) equations simultaneously.
------------------------
Part B
Pick any two points you want from the f(x) curve. You could pick the solution we mentioned, but I'll go for (0,0) and (2,2). When talking about a single curve, it has infinitely many solutions (as long as you pick a point on the curve).
------------------------
Part C
Ignore the f(x) curve. The graphs of p(x) and g(x) intersect when x = -6, which is the solution to the equation p(x) = g(x). We're only concerned about the x coordinate of the intersection.
Answer:
34
Step-by-step explanation:
-8(5 - 4x) + 6w
Let x= 4 and w = -9
-8( 5 - 4(4)) + 6(-9)
Parentheses first
-8 (5-16) -54
Multiply and divide
-8(-11) -54
88 -54

There are markings given in the diagram.
(Angle) ∠A and ∠D are =
(Side) AC and DB are =
(Side) In a trapezium, the opposite sides are equivalent, meaning AB and DC are =
So you got side, angle, and another side.
You can form the SAS (Side-Angle-Side) similarity theorem.
You can also use the reasons above to make a Statement-Proof table
