Given:
The equation of a line is:
[tex]y=-\dfrac{5}{7}x+2[/tex]
A line passes through the point (-5,-3) and perpendicular to the given line.
To find:
The equation of the line.
Solution:
Slope intercept form of a line is:
[tex]y=mx+b[/tex] ...(i)
Where, m is the slope and b is the y-intercept.
We have,
[tex]y=-\dfrac{5}{7}x+2[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]m=-\dfrac{5}{7}[/tex]
We know that the product of slopes of two perpendicular lines is always -1.
[tex]m_1\times m_2=-1[/tex]
[tex]-\dfrac{5}{7}\times m_2=-1[/tex]
[tex]m_2=\dfrac{7}{5}[/tex]
Slope of the required line is [tex]\dfrac{7}{5}[/tex] and it passes through the point (-5,-3). So, the equation of the line is:
[tex]y-y_1=m_2(x-x_1)[/tex]
[tex]y-(-3)=\dfrac{7}{5}(x-(-5))[/tex]
[tex]y+3=\dfrac{7}{5}(x+5)[/tex]
Using distributive property, we get
[tex]y+3=\dfrac{7}{5}(x)+\dfrac{7}{5}(5)[/tex]
[tex]y+3=\dfrac{7}{5}x+7[/tex]
[tex]y=\dfrac{7}{5}x+7-3[/tex]
[tex]y=\dfrac{7}{5}x+4[/tex]
Therefore, the equation of the line is [tex]y=\dfrac{7}{5}x+4[/tex]. Hence, option A is correct.

Does anyone know the answers with big ideas!
Answer:
k = 3
Step-by-step explanation:
Parent function is f(x) = [tex]0.25^{x}[/tex]
As shown in the graph, function 'f' has been shifted 3 units upwards to form an image function 'g'.
If the given function is shifted 3 units upwards, equation of the new function will be,
g(x) = [tex]0.25^{x}+3[/tex]
Therefore, the value of k will be,
k = 3
What is infinity + infinity??
Answer:
Although this makes for a lot of potential fun with formulas, mind experiments and arguments, the answer is plain.
Infinity is already everything so there is no more to it, infinity plus infinity would be still just infinity, which is btw infinite.

Ifthe fish commission states that the mean length of all fish in spring run is mean =15cm,withthe standard deviation of variance=4cm,what will be the probability that a fish is caught in spring run :between 15cm&19cm?
Answer:
Step-by-step explanation:
z(lower) = (15-15)/4 = 0
z(upper) = (19-15)/4= 1
z at 0 = .5
z at 1 = 0.841344746
(look these up in a Z table)
probability "between" = 0.841344746 - .5 = 0.3841344746
0.384 is the probability that a fish is caught in spring run between 15cm and 19cm
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
Given that fish commission states that the mean length of all fish in spring run is mean =15cm
the standard deviation of variance=4cm,
We need to find the probability that a fish is caught in spring run :between 15cm and 19cm
The z score formula is z=x-µ/σ
z(lower) = (15-15)/4 = 0
z(upper) = (19-15)/4= 1
From the table of z values we get
z at 0 is 0.5
z at 1 is 0.841344746
probability between 0.841344746 -0 .5 is 0.3841344746
Hence, 0.384 is the probability that a fish is caught in spring run between 15cm and 19cm

If the area of a circle is 36 pi, what is it's circumference?
Answer:
C = 12π or 37.7
Step-by-step explanation:
A = πr²
36π = πr²
π's get divided out and you are left with:
r² = 36
if you take the square root of 'r' it will equal the square root of 36, which is 6
C = 2πr
C = 2π(6)
C = 12π or 37.7
Answer
the answer is 12*sqrt pi

A) The axis of symmetry is x = 1.5 and the vertex is (1.5, 12.75).
B) The axis of symmetry is x = −1 and the vertex is (−1, −3).
C) The axis of symmetry is x = −1.5 and the vertex is (−1.5, 8.25).
D) The axis of symmetry is x = 0 and the vertex is (0, 6).
Answer:
C) The axis of symmetry is x = −1.5 and the vertex is (−1.5, 8.25).
Step-by-step explanation:
The axis of symmetry is x = − b/2a
= -(-3) / 2(-1)
= 3/(-2)
= -1.5
the vertex => x = -1.5
y= -(-1.5)²-3(-1.5)+6 =

4x=6y= 6 and 2x+5y=11 by elimination show all work
Please help me!!! I will mark brainlist !!
Answer:
ans: x= 11/4 and y= 11/8
Step-by-step explanation:
4x=6y=6 mean
4x= 6 and 6y= 6 so, 6-6=0 i.e
4x - 6y = 0 say equation ....1
and given
2x + 5y = 11 say equation ....2
to solve by eliminating methods,
multiply equation....2 by 2 and subtract from ....1
i.e
4x - 6y =0
4x + 10y= 22
(-) (-) (-)
0+ (-)16y = - 22
y = -22/-16
y = 11/ 8
to get , x put y in either equation 1 or 2
I.e x= 11/4

Una empresa fabrica protectores faciales, según los estudios de mercado que se han hecho, se ha de vender a S/.9 la unidad. La empresa tiene unos gastos fijos mensuales de local y personal de S/.9000, y además, fabricar cada unidad protector facial cuesta S/. 3. ¿Cuántas unidades ha de vender mensualmente si no quiere tener pérdidas?
Answer:
The number of units sell is 2.
Step-by-step explanation:
selling cost of one unit = $ 0.9
Monthly expense = $ 0.9
Manufacturing cost = $ 0.3
Let the number of unit sell is x.
So,
0.9 x = 0.9 + 0.3 x
0.6 x = 0.9
x = 1.5
So, the number of units sell to get no loss is 2.

Given that y is directly proportional to x. If y = 30 and x= 5, write an equation that connects y with x.
Answer: y = 6x
Step-by-step explanation:
Since this is a direct proportion, we will introduce the constant of proportionality here and this will be:
y = kx
Since y = 30 and x= 5,
30 = 5 × k
30 = 5k
k = 30/5
k = 6
Therefore, the equation that connects y to x will be:
y = kx
y = 6x
The equation that connects y to x is y = 6x.

The seventh grade wants to break last year's record of 78 coats collected for the annual clothing drive. They have already collected 13 coats.
Which number line represents the graph of the solution to the inequality that represents the number of coats, c, that the seventh grade must still collect?
Answer:
The last number line or D.
Step-by-step explanation:
To find the remaining coats to be collected, subtract the coats that are collected from the total of coats needed.
So:
78 - 13= 65
They must collect a total of 65 and more to break the last year's record of 78 coats. Number line D, represents the solution of this inequality.
Hope this helps! Have a nice dayy! :)
