A group of friends are at a baseball game and are purchasing souvenirs. Dustin purchased 5 t-shirts and 1 baseball cap, spending a total of $119. His Mandy purchased 1 t-shirt and 1 baseball cap, which cost her a total of $43. Assuming that all of the t-shirts and all of the caps are the same price, what is the price of each?
Shirts are $____apiece and caps are $___apiece.
help thanks
Answer:
Shirt-$19
Cap-$24
Step-by-step explanation:
5s+1c=119
1s+1c=43
1c=43-1s
substitute:
5s+(43-1s)=119
5s+43-1s=119
4s=119-43
4s=76
1s=19
substitute:
1c=43-(19)
1c=24

We are given
[tex]( \sqrt{3} + \sqrt{7} )( \sqrt{7} - \sqrt{3} )[/tex]
We want to consolidate the equation firstWe get an answer of 4Answer:
4
Step-by-step explanation:
Using the rule of radicals
[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex] and [tex]\sqrt{a}[/tex] × [tex]\sqrt{a}[/tex] = a
Given
([tex]\sqrt{3}[/tex] + [tex]\sqrt{7}[/tex] )([tex]\sqrt{7}[/tex] - [tex]\sqrt{3}[/tex] )
Each term in the second factor is multiplied by each term in the first factor, that is
[tex]\sqrt{3}[/tex] ([tex]\sqrt{7}[/tex] - [tex]\sqrt{3}[/tex] ) + [tex]\sqrt{7}[/tex] ([tex]\sqrt{7}[/tex] - [tex]\sqrt{3}[/tex] ) ← distribute both parenthesis
= [tex]\sqrt{21}[/tex] - 3 + 7 - [tex]\sqrt{21}[/tex] ← collect like terms
= 4
Write an equation of the line with a slope of -7 and y-intercept of 1
Answer:
y = -7x + 1
Step-by-step explanation:
You put it in the form y = m*x + b
Where m = the slope, so -7 and b = the y-intercept, so 1.
This means it's y = -7x + 1
Note: this answer assumes the equation can be put in slope-intercept form.
Answer:
y = -7x + 1
Step-by-step explanation:
Slope-intercept form, or y = mx + b format, is written in a way that easily reflects the slope and y-intercept of a line. The m, or the coefficient of the term with the x, represents the slope. The b represents the y-value of the y-intercept.
Therefore, substitute the number -7 and 1 in place of those variables. Since -7 is the slope, substitute in place for m. Since 1 is the y-intercept, substitute in place of b. This gives us the equation y = -7x + 1.

Answer:
x = 9
y = 6
Step-by-step explanation:
Since, RS bisects AB,
5x - 9 = 5y + 6
5x - 5y - 9 = 6
5x - 5y = 6 + 9
5x - 5y = 15
x - y = 3 -------(1)
And RS = 36
Since, RS = RT + TS
(3y - 1) + (2y + 7) = 36
5y + 6 = 36
5y = 30
y = 6
From equation (1),
x - 6 = 3
x = 9

To answer this question, I'll make use of the following polynomial.
[tex]p(x) = x^3 - 7x^2 + 15x - 9[/tex]
When factorized, the polynomial is:
[tex]p(x) = (x - 1)(x - 3)(x-3)[/tex]
[tex]p(x) = (x - 1)(x - 3)^2[/tex]
x-1 can be expressed as [tex](x - 1)^1[/tex]
So, we have:
[tex]p(x) = (x - 1)^1(x - 3)^2[/tex]
The sum of multiplicity (M) of the equation is 3.
This is so because
[tex]x - 1[/tex] occurred one time in [tex]p(x) = (x - 1)(x - 3)^2[/tex]
[tex]x - 3[/tex] occurred two times in [tex]p(x) = (x - 1)(x - 3)^2[/tex]
[tex]Sum= 1 + 2[/tex]
[tex]Sum= 3[/tex]
The degree of [tex]p(x) = x^3 - 7x^2 + 15x - 9[/tex] or [tex]p(x) = (x - 1)^1(x - 3)^2[/tex] is 3.
This implies that:
[tex]Sum = Degree = 3[/tex]
Hence: Option (a) answers the question
A bacteria colony started with 2 bacteria. The colony is growing exponentially at 10% per hour. How long will it take to have 1 million bacteria?
Answer:
the time taken for having 1 million bacteria is 137.68 hours
Step-by-step explanation:
The computation is shown below:
y = 2 × (1.10)^x
1,000,000 = 2 × (1.10)^x
500,000 = (1.10)^x
x = log (500,000) ÷ log (1.10)
= 137.68 hours
hence the time taken for having 1 million bacteria is 137.68 hours

Which statements accurately compare the different functions check all that apply (multiple answers)
===================================================
Explanations:
Choice A) This is true. The y intercept is where graph crosses the y axis. The blue V shaped graph and the orange parabola cross at 8 on the y axis. Therefore, they have the same y intercept.Choice B) This is true. The x intercept is the same for both the orange parabola and red square root curve. They both cross or touch the x axis at 2.Choice C) This is false. For example, the value x = 0 is not in the domain of the square root function, but it is part of the domain of the absolute value function.Choice D) This is true. You have the correct answer. There is no y intercept because the square root curve does not touch or cross the y axis.Choice E) This is false. The first part about the square root function having a minimum domain value is true. This is x = 2, which is the smallest x value allowed. However, the part about the other two functions having a minimum range value is false. The arrows on the parabola indicate the curve goes forever downward. There is no smallest y value on the parabola. The same applies for the absolute value graph as well. Since both parts of choice E aren't true, this means the complete statement overall is false.Answer:
A, B, D

Answer:
C
Step-by-step explanation:
Consider the following Function:
F(x)= 7x-9
If the output is 26, what is the input?
★ Input of the given function F(x) is 5.
⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
• Given:-✯ F(x) = 7x - 9
✯ Output = 26
⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
• Solution:-According to the question the output is 26.
Hence, the above data can be written in an equation form.
⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
➪ F(x) = 7x - 9 = 26
➪ 7x = 26 + 9
➪ 7x = 35
➪ [tex]\sf x = \dfrac{35}{7}[/tex]
➪ [tex]\bold\red{x = 5}[/tex]
⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
Therefore, F(x) = 5

Whatcha table shows a proportional relationship?
p 1 3 5 7 9
q 0 2 4 6 8
—————-
b 1 4 5 7 11
c 3 12 15 21 33
——————-
r 3 6 10 12 15
s 2 4 6 8 10
——————
x 1 2 3 4 5
y 9 10 11 12 13
Answer:
The answer is the second table (the one with B and C.)
Step-by-step explanation:
You know this, because the other tables are just based on patterns and the x and y values have nothing to do with each other. However, for the second table, the b value times 3 equals the c value. This is how you know the table shows a proportional relationship, and this is key to solving this problem.
Here's an image that helps demonstrate this idea:
Given the explicit formula for an arithmetic sequence, find the first five terms and the term names in the problem: t(n) = -7.1-2.1n Find t(27)
Answer:
t(n) = -7.1 - 2.1n
t(27) = -7.1 - 2.1(27)
t(27) = -7.1 - 56.7
t(27) = -63.8

Susanna purchased a shirt for $5, pants for $10, and a jacket for $25. She wants to buy at least one purse for the outfit, but she wants to have something left of her original $65. How much money might she spend on the purse?
Answer:
$15 dollars left after you purchased everything except the purse.
Step-by-step explanation:
5+10+25=40
65-40=15
if you have $15 left it depends on how much the purse costs.
Say it costs $10 dollars you would have $5 left and so on
