We see 2 congruent angles (A and B) that adjacent to the side AB,
this is Angle- Side-Angle Theorem. (A)
For right triangle it can be called Leg-Angle theorem. (F)
It could be Side- Angle- Side theorem, because AB=XY, BC=YZ, angle B=angle Y, but for right triangle it names Leg-Leg theorem. (B)
Answer:
The equation which represents the function is given by,
x = 3y .
Step-by-step explanation:
The direct variation function contains the points, (-9, -3) and (-12, -4).
Here,
= 3
So, the equation which represents the function is given by,
x = 3y .
Answer:
The Domain is {3,2-1,0} Range {7,4,2}
Step-by-step explanation:
It is a function because there is one value of y for every x value.
Answer:
1. (4, 3) and (8, 6)
2. Yes. The line shows a direct proportion. y = 0.75x
Try (20, 15) in the equation.
15 = 0.75(20)
15 = 15
Point (20, 15) works in the equation, so point (20, 15) is on the line.
3.
Let x = 100.
y = 0.75x
y = 0.75 × 100
y = 75
Since x = 100 gives y = 75, point (100, 75) is on the line.
4.
Let x = 90
y = 0.75x
y = 0.75 × 90
y = 67.5
For x = 90, y must be 67.5. Since this point is (90, 68), it is not on the line.
Answer:
<u>f</u><u>(</u><u>5</u><u>)</u><u> </u><u>=</u><u> </u><u>1</u><u>7</u><u> </u>
Step-by-step explanation:
f(x) = 3x + 2
Since the value of x is 5, we can plug it into the equation.
f(5) = 3(5) + 2
f(5) = 15 + 2
Hope this helped :)
