Answer:
y = 50x+25
f(x) = 50x+25
Step-by-step explanation:
Using the slope intercept form of the equation, y = mx+b
where x is the amount per day and b is the flat fee
2 days
125 = 2x+b
5 days
275 = 5x+b
Subtract
275 = 4x+b
125 = 2x+b
---------------------
150 = 3x
Divide by 3
150/3 = 3x/3
50 =x
The cost per day is 50 dollars
y = 50x +b
Using the data for 2 days
125 = 50*2 +b
125 = 100 +b
125-100 = b
b = 25
The equation is y = 50x+25
f(x) = 50x+25
To graph, The x axis is number of days and the y axis is total cost
The number of days starts with 0, which is the y intercept
Let x = 0, y =25
Using the slope, we go 50 up and 1 to the right ( 50 dollars per day)
The next point plotted ins ( 1,50)
Draw a straight line
Answer:
y = 50x+25
f(x) = 50x+25

A pumpkin is thrown out of a window that is 4 feet high with an upward velocity of 14. When will the pumpkin hit
the ground?
A. 0.4 seconds
OB. 1.1 seconds
O c. 7 seconds
OD. 0.22 seconds
Answer:
Step-by-step explanation:
Given
Height H = 4 feet
Velocity = 14ft/s
Required
Time the pumpkin will hit the ground
Using the equation of mottion
H = ut + 1/2gt²
4 = 14t + 1/2(9.8)t²
4 = 14t + 4.9t²
4.9t²+14t-4 = 0
t = -14±√196+16(4.9)/2(4.9)
t = -14±√196+78.4/2(4.9)
t = -14±16.57/9.8
t = -14+16.57/9.8
t = 2.57/9.8
t = 0.2seconds

Mrs. Hollern works in a jewelry store and
earns an 8.5% commission on every piece of
jewelry she sells. How much commission
would she earn for selling a necklace that
costs $4,600?
Answer:
May 06, 2018 · Real estate agents, car dealers, and pharmaceutical sales representatives earn commissions that are a percentage, or part, of sales. For example, a real estate agent might earn a portion of the selling price of a house that she helps a client purchase or sell. A car salesperson earns a portion of the selling price of an automobile that she sells.
$391 is earned by Mrs. Hollern for selling a necklace that costs $4,600
Since a commission of 8.5%(0.085) is earned for each jewelry sold, hence the total commission (y) for selling x worth of jewelry is:
y = 0.085x
Hence for selling $4600, the commission earned is:
y = 0.085(4600)
y = 391
Hence $391 is earned by Mrs. Hollern for selling a necklace that costs $4,600.

Which are necessary conditions to apply the SAS Triangle Congruence Theorem? Select all that apply.
A. Two sides and the included angle of a triangle are congruent to the corresponding parts of another triangle.
B. Two angles and the included side of one triangle are congruent to the corresponding parts of another triangle.
C. An angle and the two sides collinear with the angle's rays are congruent to the corresponding parts of another triangle.
D. Two sides and any angle of one triangle are congruent to the corresponding parts of another triangle.
Answer:
A and C
Step-by-step explanation:
Two sides and the included angle of a triangle are congruent to the corresponding parts of another triangle.
An angle and the two sides collinear with the angle's rays are congruent to the corresponding parts of another triangle.
The statements that will apply that meets the conditions for two triangles to be considered congruent to each other by the SAS Congruence Theorem are:
A. corresponding two sides and an included angle that are congruent in both triangles
C. A pair of two sides that are collinear to an angle's ray and an angle, which are congruent to the corresponding two sides and angle in the other triangle.
Recall:
SAS Triangle Congruence Theorem states that if two triangles have a pair of corresponding two sides and an included angle that are congruent to each other, then the two triangles are considered congruent to each other.The image shows two triangles that are congruent by the SAS Congruence Theorem.Therefore the statements that will apply that meets the conditions for two triangles to be considered congruent to each other by the SAS Congruence Theorem are:
A. corresponding two sides and an included angle that are congruent in both triangles
C. A pair of two sides that are collinear to an angle's ray and an angle, which are congruent to the corresponding two sides and angle in the other triangle.

D. Can't be determined
The value of p is equal to q from the given triangles
Sum of interior angle of a triangleThe sum of interior angle of a triangls is 180 degrees
For the first triangle
p + 60 + 30 = 180
p + 90 = 180
p = 180 - 90
p = 90 degrees
For the second triangle
q + 45 + 45 = 180
q + 90 = 180
q = 90degree
