The slope of the lineing through the points (3,1) and (-2,4) is
Answer:
[tex]\boxed { m = -3}[/tex]
Step-by-step explanation:
Use the Slope Formula to help you find the slope of the two given points:
[tex]m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]
(where [tex](x_{1}, y_{1})[/tex] represents the first point and [tex](x_{2}, y_{2})[/tex] represents the second point)
-Apply the given points onto the formula:
[tex](x_{1}, y_{1}) = (3, 1)[/tex]
[tex](x_{2}, y_{2}) = (-2, 4)[/tex]
[tex]m = \frac{4 - 1}{-2 - 3}[/tex]
Solve for the slope:
[tex]m = \frac{4 - 1}{-2 - 3}[/tex]
[tex]m = \frac{3}{-1}[/tex]
[tex]\boxed { m = -3}[/tex]
Therefore, the slope is [tex]-3[/tex].

ivy bought 10 packs of cups for her holiday party. a pack of medium cups costs $1.80 and a pack of large cups costs $2.40. she paid a total of $21.60. how many packs of each size cup did she buy?
Answer:
4 packs of medium cups and 6 packs of large cups
Step-by-step explanation:
1.80x + 2.40y = 21.60
1.80(4) + 2.40(6) = 21.60
7.2 + 14.4 = 21.60
21.60 = 21.60
Answer:
Ivy bought 4 packs of medium cups, and 6 packs of large cups.
Step-by-step explanation:
To solve this problem, we will have to use a system of equations. Our first equation will represent the cups, and our second equation the costs.
Let [tex]m[/tex] equal medium cups.
Let [tex]l[/tex] equal large cups.
[tex]m+l=10[/tex]
[tex]1.80m+2.40l=21.60[/tex]
Let's use substitution to solve this system.
Subtract [tex]l[/tex] from both sides of the first equation:
[tex]m=10-l[/tex]
Let's substitute [tex]10-l[/tex] into the second equation for [tex]m[/tex]:
[tex]1.80(10-l)+2.40l=21.60[/tex]
Distribute [tex]1.80[/tex] into [tex](10-l)[/tex]:
[tex]18-1.80l+2.40l=21.60[/tex]
Combine like terms:
[tex]18+0.6l=21.60[/tex]
Subtract [tex]18[/tex] from both sides of the equation:
[tex]-0.6l=3.60[/tex]
Divide by the coefficient of [tex]l[/tex], which is [tex]0.6[/tex]:
[tex]l=6[/tex]
Ivy bought 6 packs of large cups.
_
Let's substitute [tex]6[/tex] into the first equation to find the number of medium cup packs:
[tex]m+6=10[/tex]
Subtract [tex]6[/tex] from both sides of the equation:
[tex]m=4[/tex]
Ivy bought 4 packs of medium cups.
_
We can check our work 2 ways; by substituting our solved values into the initial equations.
1st Equation Check:
[tex](4)+(6)=10[/tex]
[tex]10=10[/tex]
2nd Equation Check:
[tex]1.80(4)+2.40(6)=21.60[/tex]
[tex]7.2+14.4=21.60[/tex]
[tex]21.60=21.60[/tex]
Our answers are correct!
(0, 3); slope = -2
the answer is y= something idk
Answer:
Y= -2x+3
Step-by-step explanation:
the point (0,3) is where the y intercept is (since x is 0 and y is 3) and the -2 is the slope (or -2/1, it's still the same thing though).

One half of a number increased by 3 is five less than two thirds of the number
Answer:
12 is thy number lol
Step-by-step explanation:
1/2x + 3 = 5 - 2/3x
Subtract the 1/2x
You get 3 = 5 - 1/6x
Subtract the five.
-2 = -1/6x
Multiply by -6
x = 12
The number who's one-half increased by 3 is five less than two-thirds of itself is 48.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
Let the unknown number be represented by x.
Given the statement that "One half of a number increased by 3 is five less than two-thirds of the number". Therefore, the statement as an expression can be written as,
(1/2)x + 3 = (2/3)x - 5
Solving the equation for x,
3 + 5 = (2/3)x - (1/2)x
8 = (4/6)x - (3/6)x
8 = (1/6)x
x = 8 × 6
x = 48
Hence, the number who's one-half increased by 3 is five less than two-thirds of itself is 48.

Fred bought a burger and two orders of fries for $6.50. One order of fries is $1.50. How much was the burger?
Answer:
Step-by-step explanation:
The burger was 3 dollars and 50 cents . The two order of fries were 3 dollars
Answer:
$3.50
Step-by-step explanation:
first you take the amounts you do know, which is the total amount and the cost of one order of fries.
you know he got 2 fries, so thats 1.50 times 2.
1.50 x 2 = 3.00
then you subtract that from the total
6.50 - 3.00 and you're left with 3.50

Answer:
Add -3+8
Step-by-step explanation:
You would do this first because it is in the brackets. Usually you would do (*) first but those are just there because the 4 is negative and if they were not there it would get confusing and look like this::[-3+8]--4. So the next step would be the [*].

Answer:
Use PEMDAS
Step-by-step explanation:
Parenthesis, If there are none move on to exponents if there are no exponents move to multiplication. No multiplication? use division. If you dont see division use addition and lastly if there is no addition use subtraction. In the equation, it looks like you have to make the -3 and 8 positive. So, since the -4 is in the parenthesis(P) multiply(M) 4 by 3 and 8 once the three is positive. So your final answer would be either C or D

Does the following depict a translation,rotation, or reflection?
Answer:
This would represent a translation.
Step-by-step explanation:
It wouldn't be a reflection since both images would be reflected on the same x-axis or y-axis. And it wouldn't be rotation because the form of the shape would have been different in a way that instead of being on it's side it would have been upright. So that leaves us with translation.
Answer:
This would represent a translation.

EDGE 2020 The average monthly high temperatures for Phoenix, Arizona from the years 1981-2010 are shown in the table below, with the value 1 representing the month of January, and the value of 12 representing the month of December. Complete the following steps to model the curve using the sine function.
a. Make a scatterplot of the data.
b. What is the minimum temperature in the data set?
c. What is the maximum temperature in the data set?
d. What is the vertical shift, k, for the data set?
e. What is the amplitude, a, for the data set?
f. What is the period and frequency factor for the data set?
g. What is the phase shift for the data set?
h. Write an equation using the sine function that models this data set.
i. When would you expect the temperature in Phoenix to be 82°?
Answer:
a. Please find attached the required scatter plot
b. The minimum temperature in the data set is 67°F
c. The maximum temperature in the data set is 106°F
d. The vertical shift for the data set is 67°F
e. The amplitude 19.5 °F
f. The period is 12 months, the frequency = 1/12 months
h. The sine function equation that models the data set is 19.5·sin(π·t/6 - π/2) + 86.5
i. After the second and before the third month or after the ninth and before the 10th month
Step-by-step explanation:
The equation for the sinusoidal variation of temperature with time can be presented as follows;
y = A·sin(Bt + C) + D
Where;
A = The amplitude = (The Maximum value - The minimum value)/2
The amplitude = (106 - 67)/2 = 19.5°F
B = 2·π/(The period) = 2·π/12 = π/6
t = The time in months
C = The phase shift = -π/2
D = The midline = (The Maximum value + The minimum value)/2 = (106 + 67)/2 = 86.5 °F
The equation that models the data = 19.5·sin(π·t/6 - π/2) + 86.5
When the temperature is 82°, we have;
82 = 19.5·sin(π·t/6 - π/2) + 86.5
82 - 86.5 = 19.5·sin(π·t/6 - π/2)
-4.5°F = 19.5·sin(π·t/6 - π/2)
sin⁻¹(-4.5/12) = π·t/6 - π/2
-0.3844 = π·t/6 - π/2
-0.2329 = π·t/6 - π/2
t = 2.55 or 12 - 2.55 = 9.44
Which is either after the second and before the third month or after the ninth and before the 10th month.
In this exercise we have to use the function knowledge to calculate the temperature that is requested in each alternative, so we have to:
a. The answer is in the scatter plot
b. The minimum is 67°F
c. The maximum is 106°F
d. The vertical shift is 67°F
e. The amplitude 19.5 °F
f. The frequency is 1/12 months and the period is 12.
h. The sine function equation that models the data set is [tex]19.5sin(\pi t/6 - \pi /2) + 86.5[/tex]
i. After the second and before the third month or after the ninth and before the 10th month
The equation for the sinusoidal variation of temperature with time can be presented as follows;
[tex]y = Asin(Bt + C) + D[/tex]
Where;
A = [tex](106 - 67)/2 = 19.5\°F[/tex]B = [tex]2\pi /(T) = 2\pi/12 = \pi/6[/tex]t = 12 C = [tex]\pi/2[/tex]D = [tex](106 + 67)/2 = 86.5 \°F[/tex]The equation that models the data is given by:
[tex]19.5sin(\pi t/6 - \pi/2) + 86.5[/tex]
When the temperature is 82°, we have;
[tex]82 = 19.5sin(\pi t/6 - \pi/2) + 86.5\\82 - 86.5 = 19.5sin(\pi t/6 - \pi/2)\\-4.5\°F = 19.5sin(\pi t/6 - \pi/2)\\sin^{-1}(-4.5/12) = \pi t/6 - \pi /2\\-0.3844 = \pi t/6 - \pi /2 \\-0.2329 = \pi t/6 - \pi /2\\t = 2.55 \ or \ 9.44[/tex]
Which is either after the second and before the third month or after the ninth and before the 10th month.
