In quadrilateral ABCD, AC = x +9 and BD = 2x-11 For what value of x is ABCD a rectangle?
9514 1404 393
Answer:
20
Step-by-step explanation:
The figure will be a rectangle when the diagonals AC and BD are the same length:
AC = BD
x +9 = 2x -11
20 = x . . . . . . . add 11-x to both sides
ABCD will be a rectangle when x=20.

Write an equation of the parabola in vertex from y=a(x-h)^2 +k that passes through (-7,-15) and has vertex (-5,9).
Answer:
Step-by-step explanation:
We have the work form of the equation, and we also have values for x, y, h, and k. All we need to do is fill those in and solve for a:
[tex]-15=a(-7-(-5))^2+9[/tex]
Let's clean that up a bit.
[tex]-15=a(-2)^2+9[/tex] and
-15 = 4a + 9 and
-24 = 4a so
a = -6
Now we'll fill in the a value along with the h and k to get
[tex]y=-6(x+5)^2+9[/tex] which is choice C

4) y = -3x - 7
-6x - 2y = 14
Answer:
The system of equations has infinite solutions
Step-by-step explanation:
∵ y = -3x - 7 ⇒ (1)
∵ -6x - 2y = 14 ⇒ (2)
→ Substitute y in equation (2) by equation (1)
∴ -6x - 2(-3x - 7) = 14
→ Simplify the left side
∵ -6x - 2(-3x) - 2(-7) = 14
∴ -6x + 6x + 14 = 14
→ Add the like terms in the left side
∵ (-6x + 6x) + 14 = 14
∴ 0 + 14 = 14
∴ 14 = 14
∵ The variable is disappeared and the two sides of the equation equal
∴ The equation has many solutions
→ That means x and y can be any numbers
∴ The system of equations has infinite solutions

Jake wanted to measure the width of the pond, so
he drew this diagram of two similar triangles.
What is the approximate width, w, of the pond?
Answer:
C
Step-by-step explanation:
Applying the similar triangle theorem, the width, w, of the pond is approximately: D. 13 feet
Recall:
Similar triangles will have corresponding sides that have proportionate length based on the similar triangle theorem.
The two triangles in the diagram are similar.
Therefore, the ratio of their corresponding sides will be equal (i.e. corresponding side lengths that are proportional).
Thus:
[tex]\frac{5}{w} = \frac{7}{18}[/tex]
Divide both sides by 5[tex]w = \frac{18 \times 5}{7} \\\\w = 12.9[/tex]
Therefore, applying the similar triangle theorem, the width, w, of the pond is approximately: D. 13 feet

complete a home in 4 days. Working together, how long will it take them to decorate 2 homes?
Answer:
It will take them 4.44 days to decorate 2 homes.
Step-by-step explanation:
Given that:
Camilla can decorate a home in 5 days
Anne can complete a home in 4 days
Let,
x be the time taken by Camilla and Anne to decorate 1 home.
[tex]\frac{1}{Camilla's time}+\frac{1}{Anne's\ time} = \frac{1}{total\ time}\\[/tex]
[tex]\frac{1}{5}+\frac{1}{4}=\frac{1}{x}[/tex]
Taking LCM;
[tex]\frac{4+5}{20}=\frac{1}{x}\\\\\frac{9}{20}=\frac{1}{x}\\x=\frac{20}{9}[/tex]
Time taken by Camilla and Anne to decorate 2 homes = [tex]\frac{20}{9}*2=\frac{40}{9}[/tex]
Time taken to decorate Camilla and Anne 2 homes = 4.44 days
Hence,
It will take them 4.44 days to decorate 2 homes.

John will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $57.96 and costs an additional $0.12 per mile driven.
The second plan has an initial fee of $47.96 and costs an additional $0.16 per mile driven. How many miles would John need to drive for the two plans to cost
the same?
II miles
Х
?
So for starts we can go 0.16 x 63 miles = 10.04 so the total for the second plan would be $58 with driving 63 miles. and for the first plan would be 0.12 divided by 3 would be 0.04 so we add them together and we get $58 with driving a 3rd of a mile.
Overall:
1st plan: $58 with driving a 3rd of a mile.
2nd plan: $58 with driving 63 miles.
