Answer:
Both Jared and Nicole are correct.
Step-by-step explanation:
This is because since y = x + 10 is one equation, the equation Jared uses, he substitutes for y into the other equation.
On the other hand Nicole finds x = y - 10 in the other equation.
We can get Jared's equation from Nicole's equation by making y subject of the formula. So,
x = y - 10
So, y = x + 10 which is Jared's equation.
We can also get Nicole's equation from Jared's equation by making x subject of the formula. So,
y = x + 10
So, x = y - 10 which is Jared's equation.
Since from one equations, we can get the other, and both equations for x and y are the same from both equations, that is, from y = x + 10, we get x = y - 10 and, from x = y - 10, we get y = x + 10,both Nicole and Jared are correct
Given the diagram shown below, determine the value of x.

Please help!!! What is the equation of the line in slope-intercept form? Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer:
y = x - 40
Step-by-step explanation:
Points on the graph: (0, -40) and (60,20)
Slope:
m=(y2-y1)/(x2-x1)
m=(20+40)/(60-0)
m=60/60
m = 1
Slope-Intercept
y - y1 = m(x - x1)
y + 40 = 1(x -0)
y + 40 = x
y = x - 40
Answer:
y=-x-40
Step-by-step explanation:Slope intercept form is y=mx+b
slope=rise/run
slope= -40/40 = -1
y-y1=m(x-x1)
y-(-40)= -1(x-0)
y+40=-x+0
y=-x+0-40
y=-x-40
hope that helps?

What is the are of the shaded region. The inner square is a width of x and a length of x+7. The outer square is a length of 4x and a width of 2x + 1.
Answer:
7x²-3x
Step-by-step explanation:
What is the are of the shaded region. The inner square is a width of x and a length of x+7. The outer square is a length of 4x and a width of 2x + 1.
Area of a square = Length * Length
Area of the inner square = x (x+7)
Area of the inner square = x²+7x
Area of the outer square = 4x(2x+1)
Area of the outer square = 8x²+4x
Area of the shaded region = Area of outer square - Area of inner square
Area of the shaded region = (8x²+4x)-(x²+7x)
Area of the shaded region = 8x²+4x-x²-7x
Area of the shaded region = 7x²-3x
This gives the area of the shaded region

Gina is comparing the membership fees for two museums. The art museum charges a one-time fee of $7.25 plus $3.50 per month. - The science museum charges a one-time fee of $10.50 plus $4.50 per month. How much does she save after m months by joining the art museum instead of the science museum? (Hint: write the expressions for the art museum and the science museum FIRST and then find the difference)
Answer:
here two links for your answer. https://quizlet.com/325167814/financial-math-flash-cards/ https://quizlet.com/475135130/financial-math-e2020-flash-cards $2.5
Step-by-step explanation:
The art museum charges a one-time fee of $8.25 plus $2.25 per month.
So, the cost function for membership for x months in the art museum f(x) = 8.25 + 2.25x .............. (1)
Again, the science museum charges a one-time fee of $10.75 plus $3.5 per month.
Hence, the cost function for membership for x months in the science museum g(x) = 10.75 + 3.5x ........... (2)
So, from both the equations it is clear that for only joining the monthly charges are zero.
So, f(0) = 8.25 and g(0) = 10.75.
Therefore, Barrett will save by joining the art museum instead of the science museum by $(10.75 - 8.25) = $2.5. (Answer)

Franklin needs 1.25 meters of ribbon to wrap each gift. He has a spool of ribbon that contains 25 feet of ribbon. One meter is equivalent to approximately 3 feet. How many gifts of the same dimension can he wrap using the spool of ribbon?
Answer:
6
Step-by-step explanation:
convert 1.25 meters to feet
1 meter = 3 feet
1.25 meters = 1.25 x 3 = 3.75 feet
Number of gifts he can warp = 25 feet / 3.75 = 6.6
Becky is working on a weekly budget. She earns $385 per week. Becky spends $200 per week on rent and utilities plus $57 on food. After paying for rent, utilities, and food, Becky deposits 3/4 of the amount left over into a savings account. She spends the rest on entertainment. How much money does she spend on entertainment?
Answer:
$32
Step-by-step explanation:
200 + 57 = 257.
385 - 257 = 128
128 x 3/4 = 96 (deposited)
128 - 96 = 32
Becky spends $32 on entertainment

what is the perimeter of figure B ?
Answer:
35 for perimeter of b
122.5 for perimeter of a
Step-by-step explanation:
To find the perimeter, you add all of the values of the outside of the shape together. Since 12+9+9+5 = 35, the answer is 35.
Okay, so what you have to do is set up a proportion for a to b. To do that, you have to have a fraction where a is the numerator and b is the denominator. 7/2 equals x/35. Then cross multiply
7*35 = 2x
x = 122.5 :)
Answer:
The perimeter is 35.
Step-by-step explanation:
To find perimeter, add all the sides together.
9 + 9 + 5 + 12 = 35
The perimeter is 35.

Ramona is installing a kitchen counter that is 9 feet by 3 feet. The counter has a hole in it for a sink that is 2 feet by 3 feet. What is the area of the kitchen counter? Complete the equation to calculate the area.
Answer:
Therefore the area of the kitchen counter is 21 square feet
Step-by-step explanation:
Area of the sink = 2 x 3
= 6 square ft.
Area of the kitchen counter = 9 x 3 -(6)
=27 - 6
= 21 square ft.
The area of the kitchen counter is 21 square ft.
Answer:
Therefore the area of the kitchen counter is 21 square feet
Step-by-step explanation:
Area of the sink = 2 x 3
= 6 square ft.
Area of the kitchen counter = 9 x 3 -(6)
=27 - 6
= 21 square ft.
The area of the kitchen counter is 21 square ft.

Thanks and please shows steps. I will vote best answer and helpful and do more.
Step-by-step explanation:
tanB + cotB = (sinB)/(cosB) + (cosB)/(sinB)
= (sin2B + cos2B)/[(cosB)(sinB)]
= 1/[(cosB)(sinB)]
= (1/cosB)(1/sinB)
= (secB)(cscB)
