7. Quadrilateral WXYZ with vertices W-1, 1),
X(2,-3), Y(O.-6), and Z(-2,-5): x= -3
Answers
Answer:
Step-by-step explanation:
As given in the picture attached,
Coordinates of W → (-1, 1)
Coordinates of X → (2, -3)
Coordinates of Y → (0, -6)
Coordinates of Z → (-2, -5)
By reflecting these points across x = -3, distance between original points to the line of reflection and distance between the image points and line of reflection will be equal.
Coordinates of W' → (-5, 1)
Coordinates of Y' → (0, 0)
Coordinates of Z' → (-4, -5)
Coordinates of X' → (-8, -3)

8x – 3y = 5
3y = 2x + 1
Answers
Answer:
x = 1
y = 1
Step-by-step explanation:
this should be your answer
Answer:
(1, 1 )
Step-by-step explanation:
Given the 2 equations
8x - 3y = 5 → (1)
3y = 2x + 1 → (2)
Substitute y = 2x + 1 into (1)
8x - (2x + 1) = 5
8x - 2x - 1 = 5
6x - 1 = 5 ( add 1 to both sides )
6x = 6 ( divide both sides by 6 )
x = 1
Substitute x = 1 into either of the 2 equations and solve for y
Substituting into (2)
3y = 2(1) + 1 = 2 + 1 = 3 ( divide both sides by 3 )
y = 1
solution is (1, 1 )

Answers
Step-by-step explanation:
step 1. break up the shape into 2 triangles and one rectangle
step 2. A = area of triangle 1 (t1) + area of triangle 2 (t2) + area of the rectangle (r)
step 3. t1 = (1/2)bh where b is the base and h is the height. definition of the area of a triangle.
step 4. t1 = (1/2)(3)(2) = 3ft^2.
step 5. t2 = (1/2)(3)(3) = 4.5ft^2.
step 6. r = bh where b is the base and h is the height. definition of the area of a rectangle.
step 7. r = bh = (8)(4) = 32ft^2.
step 8. A = t1 + t2 + r = 3 + 4.5 + 32 = 39.5ft^2.

lf p+q/s=9, q/p =4, and square q=6, what is the value of s?
Answers
Answer:
s=5
Step-by-step explanation:
The third equation implies that q=36.
Substitute for q in the second equation to get
36/p=4
Now solve for p
p/36=1/4
p=36/4=9
Solve the first equation for s.
s/(p+q)=1/9
s=(p+q)/9
Now substitute for q and p in this equation.
s=(9+36)/9=45/9=5

In a high school stadium there are 750 seats. There are twice as many seats in the home
section as there are in the visitor section. Which system of equations could be used to
determine the number of seats in the home section, h, and the number of seats in the
visitor section, v, in the stadium?
PLEASE HELP HURRY PLEASEEE
Answers
Answer:
There are 250 home section and 2(250) = 500 visitor section.
Step-by-step explanation:
Let there are h number of seats in the home section and v is the number of seats in the visitor section.
h+v = 750 ...(1)
There are twice as many seats in the home section as there are in the visitor section.
v = 2h ...(2)
From equations (1) and (2).
h+2h = 750
3h = 750
h = 250
Hence, there are 250 home section and 2(250) = 500 visitor section.

Answer:
(x, y, z) = (49, 58, 122)
Step-by-step explanation:
The same-side exterior angles have a sum of 180°.
(x +9) +(3x -25) = 180
4x -16 = 180
x -4 = 45
x = 49
Vertical angles are congruent:
y = 49 +9 = 58
z = 180 -y = 122 = 3(49) -25

Lin's sister has a checking account. If the account balance ever falls below zero, the bank charges her a fee of $5.95 per day. Today, the balance in Lin's sister's account is -$2.67. In 14 days, Lin's sister will be paid $430 and will deposit it into her checking account. If there are no other transactions besides this deposit and the daily fee, will Lin continue to be charged $5.95 each day after this deposit is made? Explain or show your reasoning.
Answers
Answer: No, the bank will not keep charging her the $5.95 after the deposit is made.
Step-by-step explanation:
Today, Lin's sister's balance is -$2.67
She gets charged $5.95 per day.
There are 14 days until she can charge some money in the bank account, so the bank will charge $5.92 14 times
So her balance after 14 days will be:
Balance = -$2.67 - $5.95*14 = -$85.97
When she charges the $430 in the account, her balance will be:
Balance = -$85.97 + $430 = $344.03
So now she has a positive balance, which means that the bank does not charge her anymore.
