This summer Paige's town will be hosting a series of 9 concerts. There are two types of seats at the concerts, which are priced at $29.50 and $43.00. Paige would like to attend at least 5 concerts and spend no more than $200. If x and y represent the number of tickets Paige purchased for the 2 types of seats, which system of inequalities could Paige use to model this situation?
Answer:
x ≥ 0
y ≥ 0
x + y ≥ 5
29.50 × x + 43.00 × y ≤ 200
= 29.50x + 43y ≤ 200
Step-by-step explanation:
From the question we are told that:
If x and y represent the number of tickets Paige purchased for the 2 types of seats, Paige would like to attend at least 5 concerts.
The inequalities that models the situation above is given as:
x ≥ 0
y ≥ 0
x + y ≥ 5
Also from the question, we were told that: There are two types of seats at the concerts, which are priced at $29.50 and $43.00. Paige would like to attend at least 5 concerts and spend no more than $200.
The inequalities that models the situation above is given as:
29.50 × x + 43.00 × y ≤ 200
29.5x + 43y ≤ 200
Therefore, the system of inequalities that could Paige use to model this situation is:
x ≥ 0
y ≥ 0
x + y ≥ 5
29.50 × x + 43.00 × y ≤ 200
= 29.5x + 43y ≤ 200
Answer:
d) x ≥0
y ≥ 0
x + y ≥ 5
29.5x + 43y ≤ 200

a rectangular piece of metal is 15in longer then it is wide. squares with sides 3in long are cut from the four corners and the flaps are folded upward to form an open box. if the volume of the box is 1092in cubed what were the original dimensions of the piece of metal?
Step-by-step explanation:
Let x equal the width of the box and x + 15 equal the length of the box. Subtract 6 (the amount cut out) from both of the these to get the following terms: (x+9) and (x-6). These are the length and width of the box respectively. We also know that the height of the box is 3. Plugging these into the formula for the volume of a box gives you:
3(x+9)(x-6)=1092
Expanding this out gives:
3x^2+9x-162=1092
Subtract 1092 from both sides to make the quadratic equation equal zero. Plug the a, b and c coefficients into the quadratic formula (or factor) to find x.
3x^2 +9x-1254 = 0
a = 3 b = 9 c = -1254

Lilyworks for a florist. She worked 20hours last week and earned $200.00. At that rate, how much will she earn if she works for 10 hours?
Answer:
$100
Step-by-step explanation:
Answer:
$100
Step-by-step explanation:
She will earn $100 because since 20 is just 10 times 2, she will earn half as much as she did in 20 hours. 200/2 is 100.
BC = 6x + 6,
AB = 8 +9, and
AC = 141.
Find BC
Answer: 60
Step-by-step explanation:
Since AB and BC creates AC, we can add them together to find x, then use that to find the value of BC.
8x+9+6x+6=141 [combine like terms]
14x+15=141 [subtract both sides by 15]
14x=126 [divide both sides by 14]
x=9
Now that we have found the value of x, we can plug that into BC.
6(9)+6 [multiply]
54+6 [add]
60
Now, we know the length of BC is 60.
Answer:
60

11
Step-by-step explanation:
Hope this helps. :)
Answer:
5x + 3y = 11
Step-by-step explanation:
x = 4 y = -3
=5x + 3y
=5(4) +3(-3)
=20 + (-9)
=11
When a number and variable are right beside each other it means that the number and the variable are being multiplied together, for example 5x. If x = 4 then it means that 5 and 4 are being multiplied.

what is the range of the function below in set builder notation? y=|x-3|
Answer: [tex]\{y | \ y \in \mathbb{R}, \ y \ge 0\}[/tex]
This translates to "y is any real number such that it is 0 or larger".
The reasoning is that the result of any absolute value function is either 0 or positive. In other words, we'll never get a negative result of an absolute value function. This is due to how absolute value represents distance. Negative distance does not make sense.
So if y = |x-3| then y = 0 is the smallest output possible. We could have any positive output we want.
In terms of a graph (see below), the V shape is at the lowest point (3,0). The y coordinate is all we care about in terms of finding the range. So we see the lowest y value is y = 0.

Rearranging Equations: Solve the equation for y: 8x + y = 14 Solve the equation for x: -9x + 3y = 18
Answer:
y=14-8x
x= -2 + 3y/9x
Step-by-step explanation:
8x+y=14
isolate y so you get:
y=14-8x
-9x+3y=18
isolate x so you get:
-9x=18-3y
divide on both sides to get x by itself
-9x/-9x 18-3y/-9x
x= -2 + 3y/9x

Study the red pre-image and the associated blue dilation image. The center of dilation is (2, 2). What is the scale factor of the dilation?
A.) 12
B.) 8
C.) 3
D.) 1/3
Answer: The Answer is C
I just took the test
Step-by-step explanation:
The scale factor of the dilation is 3. The correct option is C.
What is the scale factor?The scale factor is defined as the proportion of the new image's size to that of the previous image. decision-making. Dilation is the process of increasing the size of an object while maintaining its shape. Depending on the scale factor, the object's size can be increased or decreased.
From the given image:-
The initial size in the image is calculated as 11 - 2 = 9
The dilated size in the image is calculated as 5 - 2 = 3
The scale factor will be given as:-
Scale factor = ratio of the initial size to the dilated size
Scale factor = Initial size / Dilated size
Scale factor = 9 / 3 = 3
Therefore, the scale factor of the dilation is 3. The correct option is C.

4) How many km in
58,795cm?
Please help thanks!!
Step-by-step explanation:
1 km is equal to 100,000 cm.
58,795 is close to 50,000, which is half of 100,000. So our estimate would be 1/2 km to 50,000 cm.
Convert 58,795 to a decimal.
0.58795
The decimal cannot be simplified so there is
0.58795 km in 58,795 cm

Brad's checking account starts off with a balance of $126.50. Throughout the week, Brad pays a bill for $87.21, and pays $5.64 for breakfast. He deposits $15.00 but then pays another bill for $55.25. At the end of the week, he gets a notice from the bank that he has a negative balance. How much does Brad need to deposit into his account to get to a $0 balance?
Answer:
$6.6
Step-by-step explanation:
Let's find out what his balance is after those transactions.
Initial balance: 126.50
After bill:
126.50 - 87.21 = 39.29
After breakfast:
39.29 - 5.64 = 33.65
After deposit (we're adding money now!):
33.65 + 15 = 48.65
After 2nd bill:
48.65 - 55.25 = -6.6
We find that his balance is negative $6.6. Thus, to get to $0, he needs to deposit an additional $6.6.
Answer: $6.6
