Answer:
She has drunk 66.67% of cups of juice in 6 days.
Step-by-step explanation:
Bella drank 2/3 cups of orange juice in 6 days.
It means that if there are 'x' number of cups, then she has drunk [tex]\frac{2}{3}x[/tex] of orange juice.
In other words, she has drunk 66.67% of cups.
For example, if the total number of cups = x = 9
Then she has drunk:
2/3 × 9 = 6 cups in 6 days.
Therefore, we conclude that for 6 days, she has drunk [tex]\frac{2}{3}x[/tex] of orange juice if there are 'x' number of cups.
Thus, she has drunk 66.67% of cups of juice in 6 days.

Answer:
Hopefully this makes sense, but x=+1 and y=-4
Step-by-step explanation:
Lets start with Y. how do you go from 7 to 3? you subtract 4. then, how do you go from 3 to -1? Well... lets subtract till we get to -1. That would be -4. Can you do that for the rest? if so, your answer is -4 for y. for x it just adds a number each time.

Find the value for y so that PQ is perpendicular to RS
P(6.–2). Q(-2,8). R(-1.3), S(-9.y)
-1
0
1
2.
Answer:
A. -1
Step-by-sep explanation:
If PQ is perpendicular to RS, therefore, the slope of RS would be the negative reciprocal of PQ.
Slope of PQ:
P(6,-2), Q(-2, 8)
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{8 -(-2)}{-2 - 6} = \frac{10}{-8} = -\frac{5}{4} [/tex]
Slope of RS:
Slope of RS is the reciprocal of the slope of PQ, since they are perpendicular.
⅘ is the reciprocal of -⁵/4. Therefore, the slope of RS = ⅘.
Use the slope formula to find the value of y in R(-4, 3), S(-9, y).
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Plug in the value
[tex] \frac{4}{5} = \frac{y - 3}{-9 -(-4)} [/tex]
[tex] \frac{4}{5} = \frac{y - 3}{-5} [/tex]
Cross multiply
[tex] (4)(-5) = (y - 3)(5) [/tex]
[tex] -20 = 5y - 15 [/tex]
Add 15 to both sides
[tex] -20 + 15 = 5y - 15 + 15 [/tex]
[tex] -5 = 5y [/tex]
Divide both sides by 5
[tex] \frac{-5}{5} = \frac{5y}{5} [/tex]
[tex] -1 = y [/tex]
y = -1

Find the distance from A(15,21) to the line 5x +2y=4. Round your answer to the nearest tenth
Answer:The distance from a point to a line is
distance(ax+by+c=0,(x0,y0)) = abs(ax0+by0+c)/sqrt(a^2+b^2)
So first convert the formula for the line to standard form
5x+2y=4
5x+2y-4=0
a=5, b=2, c=-4, x0=15, y0=-21

Madison has set up a lemonade stand outside her house and sells small cups and large cups of lemonade. Each small cup holds 12 ounces of lemonade and each large cup hold 22 ounces of lemonade. Madison used 1240 ounces of lemonade and sold 10 more large cups than small cups. Write a system of equations that could be used to determine the number of small cups sold and the number of large cups sold. Define the variables that you use to write the system. And add the system of equations to your answer.
Answer:
small cups=30
large cups=40
Step-by-step explanation:
let x be the number of small cups and y the number of large cups.
-Given that 10 more cups than small cups of lemonade were sold:
#Before the 10 more were sold, the number of x and y sold were equal>
The number of small cups sold was 30

Sam rented a truck for one day. There was a base fee of $16.95, and there was an additional charge of 73 cents for each mile driven. Sam
had to pay $172.44 when he returned the truck. For how many miles did he drive the truck?
Answer: 134 miles
Step-by-step explanation:
f(m) = 16.95 + 0.92m
140.23 = 16.95 + 0.92m
0.92m = 140.23 - 16.95
0.92m = 123.28
m = 123.28/0.92
m = 134 miles

Write your answer in simplest form.
Answer:
The answer is undefined
Step-by-step explanation:
The slope of the line that passes through points (2, -3) and (2, 13) is not defined.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The line that passes through points (2, -3) and (2, 13)
The slope 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Plug the values to find the slope of the line:
m = (13 + 3)/(2-2) = 16/0 = not defined
Thus, the slope of the line that passes through points (2, -3) and (2, 13) is not defined.

Robert has fish, chickens, and dogs. There are 28 eyes total and 16 legs total. Also, there are twice as many fish as chickens. How many dogs are there?
Answer:
There are 2 dogs
Explaination:
If there are 28 eyes in total,
Dogs- 4 eyes
Chickens- 8 eyes
Fishes - 16 eyes
In total they have 28 eyes
if there are 16 legs,
Dogs- 8 legs
Chickens- 8 legs
Fishes- 0 legs
So,
2 Dogs
4 Chickens
8 Fishes
( the problem even said that there are twice as many fish as chickens)
A _______________ is a classification tool that reveals the various possibilities in the comparison of variables for a chi-square.
Answer:
A contingency table
Step-by-step explanation:
Hypothesis tests carried out on contingency tables are based on the chi-square, a statistic.
The contingency table is a Frequency tables of two variables presented at the same time. These tables are constructed when we represent all the levels of a variable as rows in a table and represent the other variables as columns, after which we find the joint or cell frequency for every of the cell.
-X² + 5x - 6 = 2
Using the quadratic formula
[tex]-x^2+5x-6=2\\-x^2+5x-6-2=0\\-x^2+5x-8=0\\[/tex]
↝ Form into [tex]ax^2+bx+c = 0[/tex] where a > 0 (Optional)
[tex]x^2-5x+8=0[/tex] ↝ Multiply -1 for both sides.
↝ Then proceed with the Quadratic Formula.
x = [-b ± (√b²-4ac)]/2a ↝ Quadratic Formula
[tex]x=\frac{-(-5)+-\sqrt{(-5)^2-4(1)(8)}}{2(1)}\\x=\frac{5+-\sqrt{25-32}}{2}\\[/tex]
↝ As you can see that inside the square root, the numbers cannot be negative. Therefore, the solutions are imaginary.
↝ Solution with Real Numbers System ↝ There are no real solutions.
↝ Solution with Complex Number System ↝
[tex]x=\frac{5+-\sqrt{25-32}}{2}\\x=\frac{5+-\sqrt{-7}}{2}\\x=\frac{5+-\sqrt{7}i }{2}[/tex]
Therefore, the answer for Complex Number System is (5±√7i)/2

Answer:

Step-by-step explanation:
The slop is rise over run
which means we need to find the rise over run of this equation:
So the question is how many times do you need to go up/down to get to the next plot on the graph? (Reminder up is positive while down is negative)
So, you go down 5 times which means the top of the slope is -5
Now, how many times do we need to run to get the next plot?
You need to run 4 times to the right to get the next point now we have all the things to solve the problem:
Slope=rise/run
Answer: -5/4

Which expression is equivalent to -3(4c-2) -2c
A. -8c
B. 8a -34
C. -26a
D. 8a + 7
Answer:
-3(4c-2) -2c = -14c+6
Step-by-step explanation:
We need to find the equivalent expression for -3(4c-2) -2c.
First we open the brackets as follows :
-3(4c-2) -2c
= -12c+6-2c
=-12c-2c+6
=-14c+6
So, the equivalent expression is -14c+6.

What is the x-intercept of this line?
please help ahhh
9514 1404 393
Answer:
(3, 0)
Step-by-step explanation:
The line through these points intersects the x-axis at x=3.
The x-intercept is (3, 0).
_____
The x-intercept can be computed from ...
x-intercept = x1 -y1(x2 -x1)/(y2 -y1)
= -3 -(-4)(6-(-3))/(2-(-4)) = -3 +4(9/6) = -3 +6
x-intercept = 3
__
Here, it is simple enough to plot the points and see where the line crosses the x-axis.
