Answer:
B
Step-by-step explanation:
Just took the quiz!
The solution is : B = Barbara’s equation did not consider the number of bottles of iced tea.
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
here, we have,
given that,
Barbara sells iced tea for $1.49 per bottle and water for $1.25 per bottle.
Let the water bottles she needs to sell be = x
Let the iced tea she needs to sell be = y
As she wants $100, she has to sell the following numbers of drinks.
1.25x + 1.49y = 100
But, Barbara wrote an equation
1.25x + 1.49 = 100
She did not put a variable with 1.49, that will depict the number of iced teas she needs to sell.
Hence, option B is correct.

evaluate the expression for the given value of x.
2x-6;x=9
Answer:
12
Step-by-step explanation:
2x - 6 = ?
x = 9
You substitute x for 9: the value of x.
2(9) - 6 = ?
2 * 9 = 18
18 - 6 = 12
So your answer is 12.

I really don’t get this question can someone help me
======================================================
Explanation:
Points are of the form (x,y), where y = f(x) since y and f(x) are outputs.
When we vertically stretch by a factor of 3, we are making the function curve 3 times more stretched out along the vertical y axis. So a general point (x,y) becomes (x,3y). Whatever the y coordinate is, we multiply by 3 to get its stretched out counterpart.
Eg: (0,-2) on f(x) moves to (0,-6) which is on g(x)
-------------
Since y = f(x), and we're multiplying y by 3, we can say
f(x) = |x-3| - 2
3*f(x) = 3*( |x-3| - 2 )
3*f(x) = 3|x-3| + 3(-2)
3*f(x) = 3|x-3| - 6
g(x) = 3|x-3| - 6
In which of these figures appear to contain a set of lines that is neither parallel nor perpendicular?
Answer:
D
Step-by-step explanation:
The lines in A meet at a right angle (90°) so they are perpendicular.
The lines in B meet at a right angle (90°) so they are perpendicular.
The lines in C do not meet and appear to be parallel.
The lines in D meet at an angle that does not appear to be 90°, so they are neither perpendicular nor parallel.

5 positive integers are arranged in ascending order, as follows:

There are 2 modes.
Find x.
A mode is a number that shows up more often than other numbers.
The number 5 would be a mode because there are two of them.
Since there are 2 modes and the numbers go from smallest to largest x would need to be 9, so there would be two 9’s

What is the point-slope form of the equation for the line with a slope of -2 that passes through the point (4, -6)?
Answer:
y + 6 = - 2(x - 4)
Step-by-step explanation:
The equation of a line in point- slope form is
y + b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = - 2 and (a, b) = (4, - 6) , thus
y - (- 6) = - 2(x - 4) , that is
y + 6 = - 2(x - 4)

Write an equation for the nth term of the arithmetic sequence. Then find a50.
1/3 , 1/2 , 2/3 , 5/6
Step-by-step explanation:
Since the sequence above is an arithmetic sequence
For an nth term in an arithmetic sequence
A(n) = a + ( n - 1)d
where a is the first term
n is the number of terms
d is the common difference
From the question
a = 1/3
d = 1/2 - 1/3 = 1/6 or 2/3 - 1/2 = 1/6
Substitute the values into the above formula
That's
[tex]A(n) = \frac{1}{3} + (n - 1) \frac{1}{6} \\ = \frac{1}{ 3} - \frac{1}{6} + \frac{1}{6} n [/tex]So the nth term of the sequence is
[tex]A(n) = \frac{1}{6} + \frac{1}{6}n[/tex]For a50 since we are finding the 50th term
n = 50
So we have
[tex]A(50) = \frac{1}{6} + \frac{1}{6} (50) \\ = \frac{1}{6} + \frac{25}{3} [/tex]We have the final answer as
[tex]A(50) = \frac{17}{2} [/tex]Hope this helps you

Answer:
a(n)= 4*n+1
a(n+1)=5+4*n
Step-by-step explanation:
The sequence 5, 9, 13, 17 is the ariphmetic progression where a(1)=5 is the first member of the progression and the diference is d=9-5=4 (the distance between the neighboring members)
For ariphmetic progression is known that n- term is equal to
a(n)=a(1)+d*(n-1)
So for our case
a(n)=5+4(n-1)=5+4n-4=4n+1
a(n+1)= 5+4(n+1-1)= 5+4n
Joe's boat rental rents paddle boats for $8.00 and hour and the paddles rent for $5.00 for the day. If David has $45, what is the least amount of hours he could rent the paddle boat?
Answer:
Least: 1 hour
Maximum: 5 hours
Step-by-step explanation:
Given
Boat hourly rate = $8.00
Paddle daily rate = $5.00
Required
Determine the least hour, David could use the boat
First, we need to represent this as an inequality.
Since David has $45, then
[tex]\$8.00 * x + \$5.00 \leq \$45.00[/tex]
Where x represents the number of hours
Collect Like Terms
[tex]\$8.00 * x \leq \$45.00 - \$5.00[/tex]
[tex]\$8.00 * x \leq \$40.00[/tex]
Divide both sides by $8.00
[tex]x \leq \frac{\$40.00}{\$8.00}[/tex]
[tex]x \leq 5[/tex]
Hence, the least number of hour is 1 hour while the maximum is 5 hours

Answer: m∠F = 31°
Solution: The triangle's rotation is irrelevant to the measure of its angles. In other words, angles D, E, and F will all stay the same if the triangle is turned ("rotated"). That being said, we know by definition that the interior angles of a triangle add up to 180°. We are given two of the angles, and we are asked to find the third:
m∠D + m∠E + m∠F = 180°48° + 101° + m∠F = 180°149° + m∠F = 180°m∠F = 31°Dalila is mixing paste. For every 1 1/3 cups of water, she uses 2 1/2 cups of flour. How much flour does Dalila need for each cup of water? Show your work.

Flour need for 1 cup of water = [tex]1\frac{7}{8}[/tex] cups
Step-by-step explanation:
Given:
Cups of water = [tex]1\frac{1}{3}[/tex] = 4/3
Cups of flour = [tex]2\frac{1}{2}[/tex] = 5/2
Find:
Flour need for 1 cup of water

What is a linear function?A straight line on the coordinate plane is represented by a linear function.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
In another word, a linear function is a function that varies linearly with respect to the changing variable.
As per the given points,
Let's take two-point (1,1) and (2,1.5)
The slope associated with the above points will be as,
(1.5 - 1)/(2 - 1) = 0.5
Thus, the line will be y = 0.5x + 0.3
Hence "The slope of the points is closer to 0.5 thus y = 0.5x + 1.2 will be the best approximation".

What did they do incorrectly
40 + 70 + ? = 360
110 + ? = 360
-110 -110
? = 250
In the equation 40+70+?=360, they are trying to find the last angle.
First they would add 40 and 70, which is 110.
So 110+?=360
360-110=?
360-110=250
Well this is wrong, because every angle in a triangle adds up to 180 degrees.
If you are adding up the angles in a quadrilateral, only then it adds up to 360 degrees.
So they did everything right, but they didn't use the right "total degrees"
This is what it was supposed to look like.
40+70+?=180
110+?=180
180-110=?
180-110=70
?=70
