Dory and Nemo go to Taco Bell for lunch. Dory orders three soft tacos and three double deckers for 11.25. Nemo pays $10 for four soft tacos and two double deckers. Write a system of equations that represents the lunch orders for dory and Nemo.
Answers
double deckers = y
Dory
3x + 3y and the total was 11.25
11.25 = 3x + 3y
Nemo
4x + 2y and the total was 10
10 = 4x + 2y
The equations are
11.25 = 3x + 3y
10 = 4x + 2y
Hope this helps
The equations representing Dory's and Nemo's lunch orders are 3x + 3y = 11.25 and 4x + 2y = 10, respectively.
Let's define the variables first. Let x be the cost of one soft taco, and y be the cost of one double decker.
Dory orders three soft tacos and three double deckers for $11.25. This gives us the first equation:
3x + 3y = 11.25
Nemo orders four soft tacos and two double deckers for $10. This gives us the second equation:
4x + 2y = 10
We now have a system of equations that represents the lunch orders:
3x + 3y = 11.25
4x + 2y = 10
These equations can be solved simultaneously to find the individual costs of the soft tacos and double deckers.

What are the roots of the polynomial equation? x^2−12x−64=0
Answers
The roots of the polynomial equation x²−12x−64=0 are 16 and -4. These roots are calculated using the quadratic formula and represent the points where the function intersects the x-axis. The importance of finding real roots in quadratic equations is significant in solving real-world problems.
Explanation:Roots of Polynomial Equation
The roots or solutions of the polynomial equation x²−12x−64=0 can be calculated using quadratic formula. In general, the quadratic function is written as ax²+bx+c=0 and its roots are given by -b ± √(b² - 4ac) / 2a. In this case, a=1, b=-12 and c=-64.
Applying those values into the formula we get 12 ± √((-12)² - 4(1)(-64)) / 2(1) = 12 ± √(144 + 256) / 2 = 12 ± √400 / 2 = 12 ± 20 / 2. This gives us two possible roots: 16 and -4.
Graphically, these roots represent the x coordinates or points where the quadratic function intersects the x-axis on a two-dimensional graph. It is important to note that quadratic equations constructed on physical data always have real roots, which are important for solving real-world problems.

2) Find the point, M, that is five-sixths of the distance from A(-7, 2) to B(-1, -4).
Answers
point A(-7,2) and point B(-1,-4)
Step 1
find the distance AB
d=√[(-4-2)²+(-1+7)²]------------> √[36+36]
d=√72
step 2
find the point M
five-sixths of the distance from AB----------> (5/6)*√72
see the attached figure
AC/AB=x/((5/6)*AB)
6/(AB)=x/((5/6)*AB)--------> 6=6x/5
x=30/6-------> x=5
CB/AB=y/((5/6)*AB)
6/AB=y/((5/6)*AB)---------> 6=6y/5
y=30/6-------> y=5
therefore
the coordinate x of point M is
A(-7,2)
Mx=-7+5=-2
the coordinate y of point M is
A(-7,2)
My=2-5=-3
the point M is (-2,-3)

The total cost, after using a 55cents-off coupon, is $3.30. If c represents the cost of the fruit in dollars per pound, what equation could you use to find the value of c?
Answers
c= cost of fruit per pound
x= # of pounds of fruit purchased
EQUATION
T= (c)(x) - $0.55 coupon
to find c, substitute $3.30 total for T
$3.30= cx - $0.55
add $0.55 to both sides
$3.85= cx
divide both sides by x
$3.85/x= c

Which graph represents the function f(x) = log10(x + 2)?
Answers
Answer:
Please see the attachment for graph.
Step-by-step explanation:
Given: [tex]f(x)=\log_{10}(x+2)[/tex]
It is log function. First we take parent function of log
[tex]y=\log_{10}x[/tex]
We have to change y to f(x)
First we draw the graph of parent function.
[tex]y=\log_{10}x[/tex]
Now we shift graph 2 unit left because when x change to x+a , graph shift a unit left or right.
So, f(x) will shift 2 unit left.
[tex]f(x)=\log_{10}(x+2)[/tex]
Sorbet is a frozen dessert that is often made from fruit. how many portions each weighing 1/10 of a kilogram can a french dessert chef create from 3 kilograms of sorbet
Answers
We then have to do the division:
N = (3) / (1/10)
N = 30
Answer:
a french dessert chef can create 30 portions each weighing 1/10 of a kilogram from 3 kilograms of sorbet
Final answer:
A French dessert chef can make 30 portions of sorbet from 3 kilograms, with each portion weighing 1/10 of a kilogram, by simply dividing the total weight by the weight of one portion.
Explanation:
The subject of this question is Mathematics, specifically related to division and units of measurement. To find out how many portions each weighing 1/10 of a kilogram can be made from 3 kilograms of sorbet, we divide the total amount of sorbet by the weight of one portion. Therefore, we perform the division:
Determine the weight of one portion: 1/10 kg.
Divide the total weight of sorbet by the weight of one portion: 3 kg ÷ (1/10 kg).
The division gives us the result of 30 portions because 3 ÷ (1/10) is equivalent to 3 × 10.
So, a French dessert chef can create 30 portions of sorbet, with each portion weighing 1/10 of a kilogram.

The sum of the deviations about the mean always equals _________.
Answers
hope this helps :)
Final answer:
The sum of the deviations about the mean always equals zero because positive and negative deviations cancel out. This concept is essential for calculating variance and standard deviation in statistics.
Explanation:
The sum of the deviations about the mean always equals zero. When analysing a set of data, each data value has a deviation from the mean, which is the difference between the value and the mean. These deviations illustrate the spread of the data around the mean. Positive deviations occur when a data value is greater than the mean, while negative deviations occur when a data value is less than the mean.
If we sum all the deviations, the positive and negative values will cancel each other out, resulting in a sum of zero. This happens because the mean is the point where the total amount above it is equal to the total amount below it. This concept is core to understanding the calculation of other statistics such as variance and standard deviation, which provide measures of data spread. Variance is the mean of the squared deviations from the mean, and the standard deviation is the square root of the variance.
The fact that the sum of deviations equals zero is important when working with the Central Limit Theorem, as it assures that the mean of sample means will equal the population mean, assuming the sample size is sufficiently large.

Initial height of bamboo [tex]= 20 in\\[/tex]
Height of bamboo grows by [tex]24 in \\[/tex] every day

We are looking for a function with a vertex above the x-axis and a function that opens upward (has coefficient a > 0).
The first function opens downward and intersects the x-axis. The second function has a vertex below the x-axis. The third function satisfies our requirements. The fourth function has a vertex on the x-axis.
We can solve this algebraically with the knowledge that the real solutions of a quadratic are its x-intercepts. If there are no x-intercepts (because it lies entirely above or below the x-axis), then there are no real solutions. This is true when the discriminant [tex]b^2-4ac \ \textless \ 0[/tex]. You can see that from the quadratic formula. This holds true for both answers A and C, so to find the correct one, we remember that when the coefficient a of the [tex]x^2[/tex] term is positive, the graph opens upwards, so we choose C.
choice c is the correct one
Explanation:
The equation that lies completely above the x-axis should be the one having its y-values greater than zero.
