Answer:
y-3 = (-1/4)(x-4)
Step-by-step explanation:
Point-slope form is written as y-y1 = m(x-x1)
The y - 3 portion comes from the coordinate plotted, where the y-coordinate is 3, so from the function y-y1, y1 = 3.
The m equals the slope, the rise over run. Choose the two coordinates, subtract the y's from each other and the x's from each other, get the absolute value of them, and then put in the fraction (y/x) to get your slope of m. The 2 coordinates you have are (0,4) and (4,3). You subtract |4-0| and |3-4|, so you get for the x's = 4, and the y's=1. Now the slope was y/x, so 1/4 is your slope for m.
For the x, use the same coordinate you got for your y to get your x, so the x was 4.
Plug them all into the point-slope function to get your answer, which is y - (3), (-1/4) (x - [4])
Evaluate: -8/9 + 4/9 - 2/9
A. -14/9
B. -2/3
C. 10/9
D. -1/3
Answer:
-2/3
Step-by-step explanation:
Add the first two then subtract
The answer to the equation is B, [tex]-\frac{2}{3}[/tex]
First, you must add the the fractions. You add the numerator because all three fractions have like denominators.
[tex]-\frac{8}{9} +\frac{4}{9} -\frac{2}{9}=\frac{6}{9}[/tex]
Then, you must simplify [tex]-\frac{6}{9}[/tex]
[tex]-\frac{6}{9} =-\frac{2}{3}[/tex]
The answer to the equation is [tex]-\frac{2}{3}[/tex]
What is the Equation of a line that has a slope
of -3 passes to the point (4,-5)
Answer:
y= -3x + 7:)
Step-by-step explanation:
Hope this helps!
Answer:
y = - 3x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 3 , thus
y = - 3x + c ← is the partial equation
To find c substitute (4, - 5) into the partial equation
- 5 = - 12 + c ⇒ c = - 5 + 12 = 7
y = - 3x + 7 ← equation of line

Answer:
∠ A = 60°
Step-by-step explanation:
Using the sine ratio in the right triangle
sinA = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{13}{15}[/tex] , thus
∠ A = [tex]sin^{-1}[/tex] ( [tex]\frac{13}{15}[/tex] ) ≈ 60°
------------------------------------------------
Using the cosine ratio in the right triangle
cosR = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{RT}{RS}[/tex] = [tex]\frac{8}{10}[/tex] , thus
∠ R = [tex]cos^{-1}[/tex] ( [tex]\frac{8}{10}[/tex] ) ≈ 36.9° ( to 1 dec. places )

Jessica prepared 36 kilograms of dough after working 6 hours. How much dough did Jessica prepare if she worked for 8 hours? Assume the relationship is directly proportional.
Answer:
48
Step-by-step explanation:
because 36 divided by 6 is 6 and that is how much dough she produces in an hour so if you added two more 6s to 6 to make it 8 meaning you are adding 12 because that is how much dough she makes in an hour

What are the numbers so I can do the problem.
Maria found the least common multiple of 6 and 15. Her work is shown below.
Multiples of 6: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, . . .
Multiples of 15: 15, 30, 45, 60, . . .
The least common multiple is 60.
What is Maria’s error?
Maria listed some values that were not multiples.
Maria listed factors of each number instead of multiples.
Maria should have multiplied 6 and 15 to find the least common multiple.
Maria selected a multiple that is not the least of the common multiples.
Answer:
I think its "Maria selected a multiple that is not the least of the common multiples"
Step-by-step explanation:
I think the real answer would be 30 because it the lowest number that they both share....
Answer: the answer is d, she selected a multiple that is not a least common multiple. The least common multiple is the number both sets of numbers share, which would be 30.
The perimeter of a kite can be found using the formula P = 2S + 2L. Which equation expresses S in terms of P and L?
Answer:
Step-by-step explanation:
P = 2S + 2L
2S + 2L = P
2S = P - 2L
S = [tex]\frac{P-2L}{2}[/tex]
Answer:
0.5P - L
Step-by-step explanation:
P = 2S + 2L
P - 2L = 2S +2L - 2L
P - 2L = 2S
0.5P - L = S

Explain how to write an equation from a graph in slope intercept form .
Step-by-step explanation:
To write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. This is the value of m in the equation. Next, find the coordinates of the y-intercept--this should be of the form (0, b). The y- coordinate is the value of b in the equation.

The slope intercept form is given by y = mx + c
What is the Slope Intercept Form of a Line?The graph of the linear equation y = mx + c is a line with m as slope, m and c as the y-intercept. This form of the linear equation is called the slope-intercept form, and the values of m and c are real numbers.
Given here: Slope intercept form
We know that, the equation of a line in point slope form, where (x1, y1) is the point and slope m is:
(y – y₁) = m(x – x₁)
Here, (x, y₁) = (0, c)
Substituting these values, we get;
y – c = m(x – 0)
y – c = mx
y = mx + c
Therefore, the point (x, y) on the line with slope m and y-intercept c lies on the line if and only if y = mx + c
Hence, The slope intercept form is given by y = mx + c

Hello!!! Princess Sakura here ^^

So first you have to plug in what you know...
[tex]3x+y>3\\3(\frac{3}{4})+(0)>3\\\frac{9}{4}+0>3\\\frac{9}{4} >3[/tex]
If it's hard to look at it that way you should make it look like this...

Now when you look at it you can tell that it's false, so [tex](\frac{3}{4},0 )[/tex] is not a solution f this inequality.
