A) Variables:
X = number of weeks she puts money into the account.
Y = total amount in account after x weeks.
B) m would be the amount she puts in per week, b is the starting amount she has in the account
Y = 5x + 40
C) replace x with the x values in the cart and solve for y:
O : y = 40. Coordinates (0,40)
1: Y = 45. (1,45)
2: 50, (2,50)
3: 55, (3,55)
4: 60, (4,60)
D) make the graph using the above points
E) y intercept is when x is 0, which is 40. This was the starting value of how much money was saved.
Answer:
19. x=28°
<E = 67°
20. x= 9°
<L = 25°
Step-by-step explanation:
19. Supplementary means that the angles will add to make a straight line, or they will add to = 180
<L+<E = 180°
4x+1°+3x-17°=180°
7x-16°=180°
7x=196°
x=28°
Measure of Angle E
<E = 3x-17° = 3(28°)-17° = 67°
20. Vertical angles are congruent, or equal to each other.
<L = <E
2x+7° = 4x-11°
2x+18° = 4x
18° = 2x
9° = x
x = 9°
<L = 2x+7° = 2(9°)+7° = 18°+7° = 25°
12/15 = 400/500

Answer: C (Rotation, Translation and Reflection )
Step-by-step explanation:
A congruence transformation is the type that won't change the shape of the triangle.
They are the reflections(flips), rotations(turns) and translations(slides).
Answer:
140
Step-by-step explanation:
Since m∠2 is 40°, then the m∠1 is also 40°. With that, ∠1 and ∠5 are supplementary, so we have 180 - 40 = 140°
