Answer:
2.5x + 20 = y
Step-by-step explanation:
first, assign a variable to each unknown:
since we don't know how many videos were rented, that can be x, and we don't know the person's total cost, which can be y
x = number of videos rented
y = total cost
so there's always a $20 that's added on as a membership fee, which means that theres going to be a + 20 somewhere.
So, the equation is 2.5x + 20 = y

Uaing the pothagorean therom, (a squared plus b squared equals c squared) find the square of both 8 and 10 which are
8 squared - 64
10 squared - 100
Add them together to get
164
√164 = x
You can reduce that to 2√41

Mia is factoring the polynomial x2 + 4x – 12. She uses the steps shown.
A 2-column table with 4 rows. The first column has no label with entries Step 1, Step 2, Step 3, Step 4. The second column is labeled x squared + 4 x minus 12 with entries x squared + 6 x minus 2 x minus 12, (x squared + 6 x ) minus (2 x + 12), x(x + 6) minus 2(x + 6), (x + 6)(x + 2).
In which step did Mia make an error?
Step 1
Step 2
Step 3
Step 4
Mia's error is in step 4
What is factorization?Factorization involves splitting a function into several factors
The steps in factorizing the expressions are:
Step 1: x^2 + 6x - 2x -12
Step 2: (x^2 + 6x) - (2x + 12)
Step 3: x(x + 6) - 2(x + 6)
Step 4: (x + 6)(x + 2)
From the step 3 to step 4, the resulting expression should be
(x + 6)(x - 2)
However, the step 4 of the expression is (x + 6)(x + 2)
The expected expression and the actual expression in step 4 are different.
Hence, Mia's error is in step 4

Fill in the blank so that the ratios are equivalent. 3:9 and 6:
Answer: 18
Step-by-step explanation: The ratio 3:9 is equivalent to 1:3. This means that whatever number on the left side of the ratio should be multiplied by 3 to get the one on the right. 6 x 3 = 18.
The value of the unknown number for the fraction is equal to 18.
What are ratios and proportions?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.
Given that the ratio is 3:9 then the value of the unknown number will be calculated as,
The ratio 3:9 is equivalent to 1:3. This means that whatever number is on the left side of the ratio should be multiplied by 3 to get the one on the right.

Step-by-step explanation:
Answer:
b=7
area=20
a=5.66
perimeter=19.66
Step-by-step explanation:
Don't know your exact question but here goes everything:
since angle between a and b=45 degrees, b=4+3
b=7
area=(7x4)-1/2(4)(4)
area=28-8
area=20
a^2=4^2+4^2
a^2=16+16
a^2=32
a=5.66

Y = 2x
X - Y = 10
Answer:
x=-10, y=-20
Step-by-step explanation:
first you substiture the y in the second equation with the first
x-2x=10
then solve
1x-2x=-1
-x=10
multiply both sides by a negative to make the varible a
positive
x=-10
now we substitue the x in the first equation with -10
y=2(-10)
y=-20
