Answers
Given:
A new four way intersection is being constructed in New York Hyde park through point P(-3,-15).
Equation of line of one road : [tex]y=-\dfrac{3}{4}x+7[/tex].
New road that will run perpendicular to the first road
To find:
The equation of line for the new road.
Solution:
The slope intercept form of a line is
[tex]y=mx+b[/tex]
where, m is slope and b is y-intercept.
We have,
[tex]y=-\dfrac{3}{4}x+7[/tex]
Slope of this line is [tex]-\dfrac{3}{4}[/tex] and y-intercept is 7.
Product of slopes of two perpendicular line is -1.
[tex]m_1\times m_2=-1[/tex]
[tex]-\dfrac{3}{4}\times m_2=-1[/tex]
[tex]m_2=\dfrac{4}{3}[/tex]
The point slope form of a line is
[tex]y-y_1=m(x-x_1)[/tex]
where, m is slope.
The slope of new line is [tex]\dfrac{4}{3}[/tex] and it passes through P(-3,-15). So, the equation of line of new road is
[tex]y-(-15)=\dfrac{4}{3}(x-(-3))[/tex]
[tex]y+15=\dfrac{4}{3}(x+3)[/tex]
[tex]y+15=\dfrac{4}{3}x+4[/tex]
Subtract 15 from both sides.
[tex]y=\dfrac{4}{3}x+4-15[/tex]
[tex]y=\dfrac{4}{3}x-11[/tex]
Therefore, the equation of the line representing the new road is [tex]y=\dfrac{4}{3}x-11[/tex].

Step-by-step explanation:
Given the expression that Tayler tried to evaluate as:
[tex](22-5\times3) + 6[/tex]
We will solve this equation using PEDMAS
Multiplication before addition and subtraction
On solving:
[tex]Step \ 1\\= (22-5\times3) + 6\\= (22-(15)) + 6\\\\Step\ 2\\= (22-15) + 6\\\\Step \ 3\\= 7+6\\= 13[/tex]
From the steps above, we can see that Tayler made an error in step 3 by taking the difference of 7 and 6 and arriving at 1 instead of summing up to get 13 as shown above.

Do przygotowania jednej porcji gofrow potrzeba 1 i pul szklanki maki pszennej, 1i jedna trzecia szkalanki mleka oraz 0,5 szkalnki oleju pszennego. Szklanka maki wazy 16 dag, szklanka mleka-24 dag, a szklanka oleju-21,5 dag.Ile dekagramow waza lacznie skladniki potrzeba na jedna porcje gofrow?
Answers
Odpowiedź:
5,075 dekagramu
Wyjaśnienie krok po kroku:
Biorąc pod uwagę, że:
Na jedną porcję gofra:
mąka pszenna = 1 szklanka
mleko = 1 szklanka
olej pszeniczny = 0,5 szklanki
Waga na filiżankę:
1 szklanka mąki = 16 gramów
Szklanka mleka = 24 g
Dziewczęta oliwy = 21,5 g
Na jedną porcję gofra:
(1 * 16 gramów) + (1 * 24 gramów) + (0,5 * 21,5 gramów)
16 gramów + 24 gramów + 10,75 gramów
= 50,75 grama
Odwołanie :
1 gram = 0,1 dekagramu
50,75 gramów = (50,75 * 0,1)
= 5,075 dekagramu

What is the equation in point slope form for a linear function with a slope of m=−4 that passes through the point (2,−7)?
Answers
Answer: y+7=-4(x-2)
Step-by-step explanation:
point slope formula is y-y1=m(x-x1)
it gives you m = -4
(x1,y1) = (-1,-7)
y-(-7) = -4(x-2)
negative of a negative number is positive
y+7=-4(x-2)
you leave that as your answer because thats what point slope for is
its in that form ^
The equation in point slope form for a linear function is [tex]y=4x+15[/tex]
Given the following points:
Points on the x-axis = 2 Points on the y-axis = -7 Slope, m = -4
To write an equation in point slope form for a linear function:
The standard form of an equation of line is given by the formula;
[tex]y-y_1=m(x-x_1)[/tex]
Where:
x and y are the points. m is the slope.Substituting the given parameters into the formula, we have;
[tex]y-(-7)=-4(x-2)\\\\y+7=4x-8\\\\y=4x-8+7\\\\y=4x+15[/tex]
