First multiply both sides by 7, which would get you 4w= 392. Then divide each side by 4. Your answer should be w=98
Gamestop charges only $7 per used video game. Gamefly charges a one time fee of $16 plus an additional $3 per used video game. Write and solve an equation to find when the cost of buying used video games from both companies below will be the same.
Answer:
The cost of buying used video games from both companies will the same at the 4th video game.
Step-by-step explanation:
Gamestop equation: 7x
Gamefly equation: 3x + 16
7x = 3x + 16
Subtract 3x from both sides;
4x = 16
Divide both sides by 4x
x = 4
Amber bought three 8 pound bags of dog food at $2.25 per pound, two 4 pound bags of cat food at $1.75 per pound, and three 1/4 pound bags of fish food at $6.98 per pound. Approximately how much did Amber spend on pet food?
Answer:
[tex]Total = \$73[/tex]
Step-by-step explanation:
Given
[tex]Three\ 8lb = \$2.25/lb[/tex] --- Dog Food
[tex]Two\ 4lb = \$1.75/lb[/tex] ----- Cat Food
[tex]Three\ \frac{1}{4}lb = \$6.98[/tex] -------- Fish Food
Required
Determine the amount spent
For Dog Food
[tex]1\ lb = \$2.25[/tex]
Amber bought 8lb.
So, that is:
[tex]8 * 1\ lb = \$2.25 * 8[/tex]
[tex]8\ lb = \$18[/tex]
He bought 3 of those;
[tex]Cost = 3 * \$18[/tex]
[tex]Cost = \$54[/tex]
For Cat Food
[tex]1\ lb = \$1.75[/tex]
Amber bought 4lb
So, that is:
[tex]4 * 1\ lb = 4 * \$1.75[/tex]
[tex]4\ lb = \$7[/tex]
He bought 2 of those;
[tex]Cost =2 * \$7[/tex]
[tex]Cost =\$14[/tex]
For Fish Food
[tex]1\ lb = \$6.98[/tex]
Amber bought 1/4lb
So, that is:
[tex]\frac{1}{4} * 1\ lb = \$6.98 * \frac{1}{4}[/tex]
[tex]\frac{1}{4}\ lb = \$1.745[/tex]
He bought 3 of those;
[tex]Cost = 3 * \$1.745[/tex]
[tex]Cost = \$5.235[/tex]
Total amount spent is:
[tex]Total = \$54 + \$14 + \$5.235[/tex]
[tex]Total = \$73.235[/tex]
[tex]Total = \$73[/tex] (approximated)

An observation deck extends 202 feet out above the valley. The deck sits 152 feet above the valley floor. If an object is dropped from the observation deck, it's height h in feet, after t seconds, is given by h= -16t^2+152. How long will it take for the object to be 8 feet above the valley floor?
Answer:
3 secsStep-by-step explanation:
Given the height of the object as it drops from the observation deck expressed as;
h= -16t^2+152
To determine the the time it will take the object to be 8 feet above the valley floor, we will substitute h = 8 into the equation and calculate t as shown;
8 = -16t^2+152
subtract 8 from both sides
8-8 = -16t^2+152-8
0 = -16t^2+144
0-144 = -16t^2
-144 = -16t^2
16t^2 = 144
Divide both sides by 16;
16t^2/16 = 144/16
t^2 = 9
t = √9
t = 3seconds
Hence it will take 3 seconds for the object to be 8 feet above the valley floor

Answer: Choice D) [tex]y = \pm \sqrt{x+5}[/tex]
The steps to finding the inverse will have us swap x and y. Afterward, we solve for y
[tex]y = x^2 - 5 \\\\x = y^2 - 5 \\\\x+5 = y^2 \\\\y^2 = x+5 \\\\y = \pm \sqrt{x+5} \\\\[/tex]
------------------------------
Extra info:
The inverse relation is not a function because of the plus minus. For instance, plugging x = 4 into [tex]y = \pm \sqrt{x+5}[/tex] leads to y = -3 and y = 3 simultaneously. You would have to apply a domain restriction on [tex]y = x^2-5[/tex] to make it a one-to-one function, to make the inverse a function. One possible domain restriction is [tex]x > 0[/tex] which would lead to the inverse function [tex]y = \sqrt{x+5}[/tex]

The average attendance of a yearly Winter Wonderland exhibit at an amusement park is 2.8 × 10 5 people. How many people can be expected to attend over 4 years?
Answer:
1120000 attendees
Step-by-step explanation:
Given that:
Yearly Average attendance = 2.8 * 10^5 people
How many attendees can be expected to attend over 4 years
Average Yearly attendees * 4
(2.8 * 10^5) * 4
= 2.8 * 4 * 10^5
= 11.2 * 10^5
= 1120000 attendees

Use the polygon tool to graph the reflection of this rectangle across the x-axis.
Answer:
Step-by-step explanation:
From the figure attached,
Coordinates of the vertices of the given rectangle ABCD,
A(3, 6), B(12, 6), C(12, 1) and D(3, 1)
Rule for the reflection of a point across x-axis,
(x, y) → (x, -y)
After reflection of the given rectangle across x-axis image points will be,
A(3, 6) → A'(3, -6)
B(12, 6) → B'(12, -6)
C(12, 1) → C'(12, -1)
D(3, 1) → D'(3, -1)
Now we can plot these points on the graph to get the image of rectangle ABCD.

Doug dives from a platform that is 5 meters above water. His dive takes him 2.1 meters below the surface of the water. How far does Doug's dive take him?
Answer: 7.1 meters
Step-by-step explanation:
Given that :
Height of platform from which Doug dived = 5 meters above water
Doug's position after diving = 2.1 meters below water surface
How far does Doug's dive take him?
Distance above water surface to water surface = 5m
Final position to water surface = 2.1 meters
Hence, total distance covered after dive ;
5 meters + 2.1 meters = 7.1 meters
