How do you write the equation in slope intercept form given (3,-9),(0,3
Answer:
y = - 4x + 3Step-by-step explanation:
Slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{3-(-9)}{0-3}=\dfrac{12}{-3}=-4[/tex]
Point-slope frorm:
[tex]y-y_o=m(x-x_o)[/tex]
m = -4 ; point (0, 3) ⇒ x₀=0, y₀=3
y - 3 = - 4(x - 0)
y - 3 = - 4x
y = - 4x + 3 ← slope intercept form
What is x3 = 8/27
Help me please
Answer: x=8/81
Step-by-step explanation
3x divide by 3
8/27 divide by 3
it becomes x=8/27 divide by 3 and 3 becomes 1/3
8/27 x 1/3=8/81
x=8/81
The ratio of pretzels to crackers in a snack mix recipe is 11:9. What percent of the mix is
crackers?
Answer:
45%
Step-by-step explanation:
You would add 11 and 9 together to find the mix number, which would be 20. Then, you see that the crackers is 9. So, you would do 9 divided by 20 (to find the percentage). 9 divided by 20 is 0.45
0.45 as a percent is 45%.
Evaluate \left(-22\right)-14-\left(-22\right)+14(−22)−14−(−22)+14left parenthesis, minus, 22, right parenthesis, minus, 14, minus, left parenthesis, minus, 22, right parenthesis, plus, 14.
Answer:
0
Step-by-step explanation:
Given the expression
(-22)-14-(-22)+14
First you must knw the following sign operations
-×- = +
+×-= -
Using the operation in the question
(-22)-14-(-22)+14
= -22-14+22+14
= -22+22-14+14
= (22-22)-(14-14)
= 0-0
=0

Answer: 1 bulb
Step-by-step explanation:
Using the proportion of flawed bulbs in the first scenario, you can get the number of flawed bulbs in the other bath.
First scenario total bulbs = 2 + 36 = 38
Proportion of flawed bulbs = 2/38 = 1/19
In a batch of 19, the flawed bulbs are;
= 1/19 * 19
= 1 bulb

how can i find a form for y= mx + b using (200, 100) and (50,25)
Answer:
The answer is
[tex]y = \frac{7}{2}x - 600[/tex]
Step-by-step explanation:
Formula:
[tex]y = mx + b[/tex]
We first need to find the slope:
[tex] m = \frac{25 - 200}{50 - 100} = \frac{ - 175}{ - 50} = \frac{7}{2} [/tex]
Now we need to find the y-intercept:
y = mx + b (substitute)
100= 7/2(200) + b
100 = 700 + b
-700=-700
-600 = b
Using the information we now have:
[tex]y = \frac{7}{2}x \: - 600[/tex]
−2x−7y=30
7x+4y=18

A line with a slope of 5 passes through the points (3,8).which of the following is the value of the y-intercept
Answer:
-7
Step-by-step explanation:
The value of the y-intercept is -7.
Given that, slope=5 and the coordinate points is (3, 8).
What is a y-intercept?In Maths, an intercept is a point on the y-axis, through which the slope of the line passes. It is the y-coordinate of a point where a straight line or a curve intersects the y-axis. This is represented when we write the equation for a line, y = mx+c, where m is slope and c is the y-intercept.
Substitute m=5 and (x, y)=(3, 8) in y=mx+c, we get
8=5×3+c
⇒8=15+c
⇒c=-7
Therefore, the value of the y-intercept is -7.

Answer:
2s-10
Step-by-step explanation:
Answer: S - 10
Step-by-step explanation:
The question states the 3rd side is 10cm less than the 2nd side. The keyword is less, less means subtract. Knowing we have to subtract we can eliminate the 3rd and 4th answer. Since the 2nd is equal to “s”, and the third side is 10cm less than the 2nd, the 3rd side must be equal to:
“s - 10”.

(4) Fredrick borrows $ 1200 for 3 years at a rate of 5.6% per year simple
interest. Work out the total amount he pays back at the end of 3 years.
Answer:
The total amount he pays back will be $1,401.6
Step-by-step explanation:
First off, we transform 5.6% to a decimal and multiply it by 3 (years), and that will get us 0.168. Then we use the total amount borrowed and multiply it by 0.168 (total interest for 3 years). Finally, we add that to our total amount borrowed and we get the final answer.
1200 + (1200 * 0.168) = 1,401.6
The total amount he pays back at the end of 3 years is 1413.1 .
What is growth rate?Growth rates refer to the percentage change of a specific variable within a specific time period.
According to the question
Fredrick borrows $ 1200 for 3 years at a rate of 5.6% per year simple
interest.
Principal amount P = $ 1200
Time t = 3 years
Growth Rate r = 5.6 % = 0.056
Total amount = [tex]P(1+r)^{t}[/tex]
= [tex]1200(1+0.056)^{3}[/tex]
= [tex]1200(1.056)^{3}[/tex]
= 1413.1
The total amount he pays back at the end of 3 years is 1413.1 .

Which of the following equations represents an ellipse having a major axis of
length 18 and foci located at (4,7) and (4,11)?
Answer: the answer is A
Step-by-step explanation:
The equation of an ellipse having a major axis of length 18 and foci located at (4,7) and (4,11) is given by: Option A: (x-4)^2/77 + (x-9)^2/81 = 1
What is the equation of ellipse if its major and minor axis and center are given?Suppose that the major axis is of the length 2a units, and that minor axis is of 2b units, and let the ellipse is centered on (h,k) with major ellipse parallel to x-axis, then the equation of that ellipse would be:
[tex]\dfrac{(x-h)^2}{a^2} + \dfrac{(y-k)^2}{b^2} =1[/tex]
Coordinates of its foci would be: [tex](h \pm c, k)[/tex] where [tex]c^2 = a^2 - b^2[/tex]
If its major axis is parallel to y-axis, then,
coordinates of its foci would be: [tex](h , k\pm c)[/tex] where [tex]c^2 = a^2 - b^2[/tex] and its equation would be:
[tex]\dfrac{(x-h)^2}{b^2} + \dfrac{(y-k)^2}{a^2} =1[/tex]
For this case, we're specified that:
Ellipse has major axis of length 18 units,Its foci is located on (4,7) and (4,11)Assume that:
Its center is on (h,k)Its major axis is of length 2a units.Its minor axis is of length 2b units.Then, we get:
2a = 18, or a = 9 units
Also, as we have:
Coordinates of its foci as: (4,7), and (4,11)
Foci lie on major axis, and the x-coordinate of both foci is constant, so major axis is parallel to y-axis.
For such ellipse, its foci is [tex](h , k\pm c)[/tex]
The value of c is always non-negative as a ≥ b always as 2a is length of major axis and 2b is length of minor axis.
Thus, we get:
[tex]k - c = 7\\k + c = 11[/tex] (c isn't 0 as it has some effects as foci' y coordinates are different. Thus, c > 0. Andt therefore a fixed number - positive number < that fixed number + that positive number, therefore we alloted 7 and 11 to those foci).
From those 2 equations, we get:
[tex]k = c + 7\\k+ c =c+7+c = 11\\c = 2\\k = 2+7 = 9\\[/tex]
Also, from foci coordinates, we get h = 4
Thus, center of the ellipse considered is (h,k) = (4,9)
Also, as we've got [tex]c^2 = a^2 - b^2[/tex] and c = 2, and a = 9, therefore, we get:
[tex]2^2 =9^2 - b^2\\b^2 = 77[/tex]
Thus, the equation of the ellipse considered is:
[tex]\dfrac{(x-h)^2}{b^2} + \dfrac{(y-k)^2}{a^2} =1\\\\\dfrac{(x-4)^2}{77} + \dfrac{(y-9)^2}{81} =1[/tex]
Thus, the equation of an ellipse having a major axis of length 18 and foci located at (4,7) and (4,11) is given by: Option A: (x-4)^2/77 + (x-9)^2/81 = 1

A square's diagonal has a length equal to √(2) times the length of its sides. So if the side length is x, then the diagonal is such that
√(2) x = 10 cm
→ x = 10/√(2) cm ≈ 7.07 cm
The perimeter of a square is 4 times its side length, so the perimeter is
4 (10/√(2) cm) = 40/√(2) cm ≈ 28.3 cm
which makes 28.4 cm the closest answer.

A local hamburger shop sold a combined total of 628 hamburgers and cheeseburgers on Thursday. There were 72 fewer cheeseburgers sold than hamburgers
How many hamburgers were sold on Thursday?
Answer:
278 cheeseburgers and 350 hamburgers sold on Thursday
Step-by-step explanation:
To confirm that these combined equal 628 we can add them together using the equation 278 + 350. Once confirm that these both equal 628 when combined, we can find the difference between the 350 hamburgers and 278 cheeseburgers by subtracting one from the other using the equation, 350 - 278. When you do that, you will get a difference of 72 which means that there were 72 fewer cheeseburgers sold than hamburgers.
