Answer:
x = 20
Step-by-step explanation:
5x + 9 + 3x + 11 = 180
Combine like terms
8x + 20 = 180
Subtract 20 from both sides
8x = 160
Divide both sides by 8
x = 20

What is the equation written in vertex form of a parabola with a vertex of (5, 7) that passes through (2, -2)?
Answers
Answer:
y = - (x - 5)² + 7Step-by-step explanation:
y = a(x - h)² + k - vertex form of the equation of the parabola with vertex (h, k)
So the equation of the parabola with vertex (5, 7):
y = a(x - 5)² + 7
The parabola passes through point (2, -2) so if x=2 then y=-2
- 2 = a(2 - 5)² + 7
- 2 -7 = a(-3)² + 7 -7
- 9 = 9a
a = - 1
So, the equation written in vertex form of a parabola with a vertex of (5, 7) that passes through (2, -2):
y = - 1(x - 5)² + 7

find 2 consecutive integers whose sum is -97
Answers
Answer:
The first integer is: -49
The second integer: -49+1 = -48
Solution Check:
-49+(-48) = -97
Step-by-step explanation:
Let the first integer: [tex]x[/tex]
As we are looking for a consecutive integer, so
The second integer would be: [tex]x+1[/tex]
We know the sum of these two integers is -97. Thus, we can write this equation and solve for 'x'.
[tex]x+\left(x+1\right)=-97[/tex]
[tex]x+x+1=-97[/tex]
[tex]2x+1=-97[/tex]
[tex]2x=-98[/tex]
Divide both sides by 2
[tex]\frac{2x}{2}=\frac{-98}{2}[/tex]
[tex]x=-49[/tex]
Therefore,
The first integer is: -49
The second integer: -49+1 = -48
Solution Check:
-49+(-48) = -97

44 in.
Approximately how many more cups can Tony

16
Answers
Answer:
C. 16
Step-by-step explanation:
If you have 44 in space and 2 cups already on there ( 4 in) you now only have, 36 in space left.
So, 16 multiplied by 2 1/4 or 2.25 in decimal is 44 in total.
Therefore you need approximately 16 more cups.

Answer:
A) d/900 +14 +d/540 = 16
B) 675 feet
Step-by-step explanation:
A) The times are all given in minutes, so it is convenient to use units of feet and minutes in this problem. There are 60 seconds in a minute, so the bee's speeds can be rewritten as ...
15 ft/s = (15 ft/s)(60 s/min) = 900 ft/min
9 ft/s = (9 ft/s)(60 s/min) = 540 ft/min
We know that time is the ratio of distance to speed, so for distance d, we have a total time of ...
d/900 +14 +d/540 = 16
B) To solve the equation, we can subtract 14, then combine the fractions. Here, we choose to combine the fractions in a straightforward way, not being too concerned about "least common denominator." We use the formula ...
a/b + c/d = (ad +bc)/(bd)
(540d +900d)/(900·540) = 2 . . . . subtract 14, combine fractions
d = 2(900)(540)/(1440) = 675
The flowerbed is 675 feet from the hive.

Hal owns a printing company. Last Christmas, he charged $8 for a set of 25 greeting cards and $14 for a set of 50. a. Find two ordered pairs that represent the situation. (8,25) (14,50)
Answers
Answer:
(8, 25) and (14, 50)
Step-by-step explanation:
Total cost of a set of cards = price per unit x number of cards
= p x n
Thus, the total cost of printing each set of cards depends on the price per unit and number of cards. So that it can be represented in ordered pair as: (p, n).
For the first set of greeting cards,
the cost of printing a card = $8.0
number of cards printed = 25
This can be represented in ordered pair as (8, 25)
For the second set of greeting cards,
the cost of printing a card = $14.0
number of cards printed = 50
This can be represented in ordered pair as (14, 50)
Thus, the two ordered pairs that can represent the situations are (8, 25) and (14, 50).

4 and 4
-20 and -20
3 and 4
Answers
Answer:
The value of each expression when x=3 will be -20 and -20.
Step-by-step explanation:
Given the expression
-4x-8
setting x=3
= -4(3)-8
=-12-8
=-20
Given the expression
-2(x+1)-2(x+3)
setting x=3
=-2(3+1)-2(3+3)
=-2(4)-2(6)
=-8-12
=-20
so we conclude that the value of both the expressions was -20 when we substituted the value x=3.
Therefore, the value of each expression when x=3 will be -20 and -20.
