Mrs. Galicia sells online math and reading games. His revenue for each game (in dollars) is modeled by the given equations, where x is the number of days since the games went on sale.
Math Game: M(d)=2x^2+8x+2
Reading Game: R(d)=3x+5
Solve the system algebraically. After how many days is the revenue for each game the same? Show your work and explain your answer.
Graph this system to show the solutions. Label each axis appropriately.
Answers
Answer:
In the middle of a day
Step-by-step explanation:
1) Make it an actual equation
[tex]3x+5=2x^{2} +8x+2[/tex]
2) Cancel integers
[tex]3x + 3 = 2x^{2} + 8x[/tex]
3) Get rid of no exponent variables
[tex]0 = 2x^{2} + 5x - 3[/tex]
4) Factor :D
[tex](2x - 1)(x+3)[/tex]
5) Solve
2x - 1 = 0
x + 3 = 0
They will meet at -3 days (Which doesn't exist!!!) and 1/2 a day.

Talia sells educational software for a yearly salary of $65,000 plus a 2.65% commission on her total sales. If Talia sells $2.5 million of software during one year, what are Talia’s earnings for that year?
Answers
Answer:
$131250
Step-by-step explanation:
Talia's earnings during one year are equal to her base yearly salary ($65000) added to her commission. Now, to know the commission it is necessary to find the 2.65% of her total sales ($2.5 million)
Step 1. Divide the total sales or 2,500,000 by 100 considering this represents the total or 100%
2,500,000 ÷ 100 = 25000
Step 2. Multiply this number by the specific percentage (2.65)
25000 x 2.65 = 66250
Now add the commission and the yearly salary
65000 + 66250 = 131250
Hence, total earnings of Talia were $131250

If f(x)=x^2 and g(x)= (square root of x)+2, what is (g(f(2))+f(1)?
Answers
Step-by-step explanation:
I am not sure that you typed it all correctly.
but based on what is written here
f(x) = x²
g(x) = sqrt(x) + 2
so, g(f(2)) + f(1) = g(2²) + 1² = g(4) + 1 = sqrt(4) + 2 + 1 =
= 2 + 2 + 1 = 5

Solve the Quadratic
Solve for x.
x^2- x=20
Solution 1:
Solution 2:
Answers
Answer:
solution 1: 5
solution 2: -4
Step-by-step explanation:
x²-x-20=0;
(x-5)(x+4)=0;
x₁=5; x₂=-4.
Answer:
Solution 1: [tex]x = 5[/tex]
Solution 2: [tex]x = -4[/tex]
Step-by-step explanation:
The first is organize the given equation to the next form
[tex]ax^2 + bx + c[/tex]
So you substract -20 in both sides of the equation
[tex]x^2 - x - 20 = 0[/tex]
Know you can use the quadratic formula or find two number that sum give us [tex]b[/tex] and multiplied [tex]c[/tex].
[tex]b = s + r\\c = sr[/tex]
Replacing with the given values we have:
[tex]-1 = s + r\\-20 = sr[/tex]
With a trial and error the numbers are -5 and 4. Then you change the equation to
[tex]x^2 - x - 20 = (x - 5)(x + 4)[/tex]
And the equation is equal to 0 when [tex]x[/tex] is equal to 5 and -4.
3.
Graph the equation by translating y = |x|.

Marie and Jorge are both trying to lose weight. After 3 months they compared their weight loss. Marie’s weight went from 175 to 150. Jorge’s weight went from 190 to 180. Which statements are true regarding their weight loss? Select three options.
Jorge’s weight change was approximately 5%.
Marie’s weight change was approximately 14%.
Marie had the greater percent change.
Jorge had the greater percent change.
Marie’s weight change was approximately 1.4%.
Answers
Answer:
Jorge's weight change was approximately 5%.
Marie's weight change was approximately 14%
Marie had the greater percent change.
Step-by-step explanation:
Solution:
Marie's former weight = 175
New weight = 150
Difference = 175 - 150 = 25
Percentage change = 25/175 × 100
= 1/7 × 100
= 14.2%
Jorge's former weight = 190
Jorge's new weight = 180
Difference = 190 - 180 = 10
Percentage change = 10/190 × 100
= 5.26%
From the above explanation, the following are right:
• Jorge's weight change was approximately 5%.
• Marie's weight change was approximately 14%
• Marie had the greater percent change.
Answer:
Step-by-step explanation:
Jorge’s weight change was approximately 5%.
Marie’s weight change was approximately 14%.
Marie had the greatest percent change.
Marie: 175-150 = 25
What percentage is 25 of 175 = x/100 = 25/175
= 14.29%
Jorge: 190-180= 10
What percent is 10 of 190? = x/100 = 10/190
= 5.3%
Sally picks seashells by the seashore. She lost 17 of them on her way home
With the remaining seashells, she planned to fill 5 jars with the same
number of seashells in each How many seashells did Sally originally pick?
a. You do not have enough information to solve this problem. The number
of seashells in each jar is the same as the number portion of her street
address, which is a 2-digit number. The first digit is 5. The last digit is
9 less than 3 times the first digit. How many seashells did Sally plan to
put in each jar?
b. By working backwards, determine how many seashells Sally originally
picked
C. The 5 jars that Sally chose would not each hold that many seashells In
her search for a 6th jar, she discovered a few seashells in her pocket
What are possible values for the number of seashells in each of the
6 jars and the number of seashells discovered in her pocket, such that
there are no seashells left over
(I need this ASAP! Thanks in advance!)
P.S. A step by step explanation would be really helpful ☺️
Answers
Answer:
a) 56 shells in each jar
b) 297 shells were picked
c) 2, 8, 14, 20, ... shells were discovered (=2+6n); 47, 48, 49, 50, ... shells in each jar (=47+n); for n=0, 1, 2, 3, ...
Step-by-step explanation:
a)The first digit is given as 5. The second is 9 less than 3 times 5, so is
3×5 -9 = 15 -9 = 6
The 2-digit number that is Sally's house address is 56.
Sally originally planned to put 56 shells in each jar.
__
b)If each of the 5 jars has 56 shells, and Sally collected 17 more than that, she originally picked ...
5×56 +17 = 280 +17 = 297
Sally originally picked 297 shells.
__
c)We saw that the number of shells to go into jars is 280. That will fill 6 jars with ...
280/6 = 46 4/6 . . . . shells in each jar
That is, Sally can fill 6 jars with 46 shells each, and have 4 shells left over. The number of additional shells to put the same number in each jar will be a number that makes a multiple of 6 when 4 is added to it. Already we know that adding 2 shells will bring the total to 6 "extra", so will allow 1 more shell to be added to each of the 6 jars.
additional shells = 2 +6n . . . . . . for some whole number n
number in each jar = 47 +n . . . . . for the same whole number n
Sally could have discovered, 2, 8, 14, ... shells in her pocket.

(x – 7)^2 = 36
Take the square root of each side
sqrt((x – 7)^2) = sqrt(36)

x-7 = 6 x-7 =-6
Add 7 to all sides
x-7+7 = 6+7 x-7+7 = -6+7
