What is the equation of the line that passes through the point (-5, 7) and has a slope of -2/5?
Answer:
I hope that it will be help full for u
Step-by-step explanation:
As we know the equation of line is ,
y= mx+ cAs given
slope=m=-2/5
also given (x, y)= (-5, 7)
we get x=-5 , y=7
putt in the equation of line all these values we get ,
7=(-2/5)(-5) +c
c=7-2
c=5 now putt the value of c and m in equation of line we will get ,required equation of line
y = (-2/5)x + 5 Ans
Using slope intercept form, the equation of the line that passes through the point (-5,7) and has a slope of -2/5 is y = - 2/5x + 5.
What is slope intercept form?
The equation of the "straight line is in the form y = mx + b where 'm' is the slope of the line, 'b' is the y - intercept form" is called slope intercept form.
According to the question,
The line passes through the point (-5,7) and has slope of -2/5,
The equation of the straight line y = m x + c. Substitute (-5,7) and slope -2/5 in general equation we have 7 = -2/5 (-5) + c
7 = 2 + c
c = 7-2
c = 5
Hence, using slope intercept form, the equation of the line that passes through the point (-5,7) and has a slope of -2/5 is y = - 2/5x + 5.

inches, what will be the height?
Answer:
18 inches!
Step-by-step explanation:
Since you are multiplying the original size by 3 times (4 in. originally • 3 = 12 inches) you just multiple the original height by 3 (6•3=18)

Point T is at (-3, 8). What are the coordinates of T' after R(y-axis) o R(x-axis)?
Given:
Point is T(-3,8).
To find:
The coordinates of T' after [tex]R(y-axis)\circ R(x-axis)[/tex].
Solution:
We know that, [tex]R(y-axis)\circ R(x-axis)[/tex] means the figure reflected across the x-axis then reflected across y-axis.
If a figure reflected across x-axis, then
[tex](x,y)\to (x,-y)[/tex]
[tex]T(-3,8)\to T_1(-3,-8)[/tex]
If a figure reflected across y-axis, then
[tex](x,y)\to (-x,y)[/tex]
[tex]T_1(-3,-8)\to T'(-(-3),-8)[/tex]
[tex]T_1(-3,-8)\to T'(3,-8)[/tex]
Therefore, the required point is T'(3,-8).
An architect is trying different dimensions for the room shown below. Write an algebraic expression the architect can use to find the area of the room then find the area when x is 6 m. Show your work.
Answer:
x² + 12
48m²
Step-by-step explanation:
Find the diagram attached.
The room can be segregated into two rectangles
The area of the room = Area of bottom rectangle + area of the top rectangle
Area of the bottom rectangle = x * (x-3) = x² - 3x
Area of the top rectangle = 3* (4+x) = 12 + 3x
The area of the room = x² - 3x + 12 + 3x
Area of the room = x² + 12
Hence the algebraic expression that the architect can use to find the area of the room is x² + 12
Given x = 6m
The area of the room = x² + 12
The area of the room = 6² + 12
The area of the room = 36 + 12
The area of the room = 48m²
30. One segment of the Mayan civilization started in 300 B.C.E. and ended in 250 C.E. How long did that segment of the Mayan civilization last?
A. 50 years
B. 300 years
C. 250 years
D. 550 years
Answer:
D. 550 years
Step-by-step explanation:
Firstly, you need to understand the meaning of B.C.E. and C.E. B.C.E. means "Before common era", where "common era" is the year where Jesus Christ was born (I will just call it "The Year" since the name is so long). The date has been used as a dating system for many years.
In this case, 300 B.C.E. means 300 years before "The Year" whereas 250 C.E. means 250 years after "The Year". Thus, the total would be:
300 + 250 = 550 years
What does 9+10 equal?
Identify the type of slope and then find the slope of the line.
Answer:
-1/2, negative slopeStep-by-step explanation:
As per graph it is visible that the slope is negative, it goes down when x-value increases
Use two points to find the slope:
(-4, -1) and (0, -3)Slope formula:
m = (y2 - y1)/(x2 - x1)Value of the slope:
m = (-3 - (-1))/(0 - (-4)) = -2/4 = -1/2The figures are similar

Which of the following inequalities matches the graph? (1 point)
Answer: 2x + y < 7
Step-by-step explanation:
In the graph we can see that:
The line is a dashed line, and the shaded area is below the dashed line, then we will have something like:
y < a*x + b
We also can see that the slope of the line is negative, and that the y-intercept is +7
Then the inequality will be something like:
y < a*x + 7
Now we can see that the line passes through the points (0, 7) and (3, 1)
Then the slope will be:
a = (1 - 7)/(3 - 0) = -6/3 = -2
that is negative, as we already said.
Then we have:
y < -2*x + 7
we can rewrite this as:
2x + y < 7
This is the first solution shown.

Thes slope is -4/ -7
Step-by-step explanation:
You use the equation Y2 - Y1 / X2 - X1
So this would look like this: -3 -1 / 0 - 7 when you plugin the numbers
So when you do the math, you're left with -4 / -7, which is the slope

16. A truck traveling 45 miles per hour and a train traveling 60 miles per hour cover the same distance. The truck travels 2 hours longer than the train. How many hours does each travel?
What equation would represent the total distance traveled by both the train and the truck? [Hint: Remember the distance traveled formula d = rt.]
A. 105x + 90
B. 105x
C. 45x + 90
D. 60x
Answer:
The equation representing the total distance would be A. 105x + 90.
The time the truck has travelled would be 8 hours while the time traveled by the train would be 6 hours.
Step-by-step explanation:
Firstly, let's set the time travelled by the train to be x hours.
According to the question, the equation would be 45(x + 2) = 60x, because the truck has travelled 2 more hours than the train.
Hence:
[tex]45(x + 2) = 60x[/tex]
[tex]45x + 90 = 60x[/tex]
[tex]90 = 60x - 45x[/tex]
[tex]15x = 90[/tex]
[tex]x = 6[/tex]
Therefore, the truck has travelled a total of (6 + 2) hours = 8 hours, and the train has travelled for 6 hours.
Also, the equation can be found by adding both equations up:
[tex]45(x + 2) + 60x[/tex]
[tex]= 45x + 90 + 60x[/tex]
[tex]= 105x + 90[/tex]
