Answer:
y = -23x + 85
Step-by-step explanation:
for an equation to be parallel to another, they must have the same slope. So plugging in (4, -7) we get -7 = -23(4) + P. P being the new y intercept we must find. Now simple algebra add -23(4) = -92 to both sides and we get 85 = P. Plug in to y = mx + b and we get
y = -23x + 85

What is an equation in point-slope form of the line that passes through (-7. 1) and (-3, 9)?
A. y+ 3 = 2(x-9)
B. y-3 = 2(x +9)
C. y + 9 = 2(x - 3)
D. y - 9 = 2(x + 3)
Answer:
D
Step-by-step explanation:
general equation of point slope is
(y-y1)=m(x-x1) where
m-is the slope
(x1,x2) is any point that belongs to the line
For (-7,1) and (-3, 9) you have to
first find the slope
m= (y2-y1) /(x2-x1) = (9-1)/ (-3- -7)= 8/(-3+7) = 8/4 =2
second pick any of your 2 given points for example (-3, 9)
now you substitute m=2, and (-3,9) in your general equation
(y-9) = 2( x- -3) so the equation is (x-9) =2(x+3)

m =
5m + 4 = 7m + 6 solve for m
Answer: m=-1
Step-by-step explanation:
Whenever a question says "solve" it means that you have to find the constant (m in this case).
You do this by rearranging the equation so that in one side is the constant and the other side the numbers.
5m+4=7m+6 becomes: 5m-7m=6-4
Then: -2m=2
: m=-2/2
: m=-1

Graph of an inequality
The graph represented in the image is a line and we have two clear points through which the line passes.
Those points are (0,1) and (5,0).
The equation of a line can have the slope-intercept form:
y=mx+b
Substituting the point (0,1):
1=0+b
b=1
Substituting the point (5,0):
0=m(5)+1
Solving for m:
[tex]\displaystyle m=-\frac{1}{5}[/tex]
The equation of the line is:
[tex]\displaystyle y=-\frac{1}{5}x+1[/tex]
The origin belongs to the solution if we substitute (0,0) the inequality should stand:
0<1
Or:
0≤1
Since the line is dashed, the boundary line is not part of the solution
Thus the inequality is:
[tex]\boxed{\displaystyle y<-\frac{1}{5}x+1}[/tex]

om each drop-down menu. Megan's commute to work includes an 8-mile drive and a 21-mile train ride. This expression can be used to find the total time it takes Megan to get to work, where xis her average driving speed in miles/hour. 21
Answer: The answers are x+20 and 0.50 hrs
I just took the test so ik these are right
The total time it takes Megan to get to work,
⇒ (8 / x) + (21 / y)
where, x is her average driving speed in miles/hour. 2
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10
Given that:
Average driving speed = x mph
Miles driven to work = 8 mile
Miles by train to work = 21 miles
Average train speed = y
Hence, Total time taken to get to work is,
We know that;
⇒ Time taken = distance / speed
Hence,
⇒ Time taken = total distance / average driving speed
⇒ Total time taken = (8 / x) + (21 / y) hours
⇒ Total time taken = (8 / x) + (21 / y) hours

the ratio of number of girls and boys in a class is 4:3 if there are 20 girls find the number of boys. plz do it in process
Answer:
15 boys
Step-by-step explanation:
Whatever number one side of the ratio is multiplied by, the other side has to be multiplied by that same number. So, we have to find the number that 4 is multiplied by to get 20. We can represent this as an equation, where the unknown number is x:
4x = 20
Divide both sides of the equation by 4 to find the value of x:
x = 5
4 was multiplied by 5 to get 20.
To find the number of boys, multiply 3 by 5:
3 * 5 = 15
If there are 20 girls, there will be 15 boys.
