Answer:
Some Facts about lines (1) For non vertical line L, if L passes a point (x0,y0) with slope m, then an equation of line L is y − y0 = m(x − x0). (2) If a non vertical line L passes through distinct points (x1,y1) and x2(y2), then the slope of L is m = y2 − y1 x2 − x1 . x a + y b = 1.

Line segment JK is divided by point L in the ratio of 3:2. Endpoint J is at (-16, 2) and point L is at (-15, -20). What are the coordinates of endpoint K?
9514 1404 393
Answer:
K(-14 1/3, -34 2/3)
Step-by-step explanation:
The division ratio says ...
(L -J)/(K -L) = 3/2
2(L -J) = 3(K -L)
5L -2J = 3K
K = (5L -2J)/3
K = (5(-15, -20) -2(-16, 2))/3 = (-75+32, -100-4)/3 = (-43/3, -104/3)
K = (-14 1/3, -34 2/3)

Can someone help me with this
7x + 5 = 3(2x + 3) + x - 4
Answer:
Infinite Many Solutions
0 = 0
Step-by-step explanation:
7x + 5 = 3(2x + 3) + x - 4 (Given)
7x + 5 = 6x + 9 + x - 4 (Distributive Property Of Equality)
7x + 5 = 7x + 5 (Combine Like Terms)
0 = 0 (Subtraction Property Of Equality)
As you see it's the same thing in both sides and if you solve it gives 0 = 0 because it would cancel each other out and since 0 is equal to 0 it's infinite many solutions.
Example:
Brigette is putting a border around a scrapbook cover.
The cover is 12 inches tall and 14.5 inches wide. How

Answer:
Step-by-step explanation:
Brigitte is putting a border, so she needs a perimeter

The scale of a model train is 1 1 inch to 13.5 13.5 feet. One of the cars of the model train is 5 5 inches long. What is the length, in feet, of the actual train car?
Answer:
74.25feet
Step-by-step explanation:
Given the scale of a model train expressed as;
1in = 13.5feet
We are to express length of 5.5in in feet
5.5in = x
Divide both expressions
1/5.5 = 13.5/x
Cross multiply
1×x = 5.5× 13.5
x = 74.25feet
Hence the actual length of the car in feet is 74.25feet

Answer:
[tex]m\angle CBD=35^{\circ}[/tex]
Step-by-step explanation:
Since there are [tex]180^{\circ}[/tex] on each side of a line and [tex]\angle ABC[/tex] is marked as a right angle, [tex]m\angle CBE=180-90=90^{\circ}[/tex].
[tex]m\angle CBE=m\angle DBE+m\angle CBD[/tex], and [tex]m\angle DBE[/tex] is given as [tex]55^{\circ}[/tex].
Therefore, we can plug in our values and solve:
[tex]90=55+m\angle CBD,\\m\angle CBD=\fbox{35^{\circ}$}[/tex].

The sum of two numbers is 120. Three times
their difference is 48. What are the numbers?
TERS A.5(C) A.1(A), A1(B)
F. 16, 120
G 36, 52
H 52,68
J 68, 84
Pleasss help thank you :)
Answer:
The answer is 68 and 52
Step-by-step explanation:
x + y = 120
3(x - y ) = 48
We have 3x + 3y = 360
and 3x - 3y = 48
Adding we have the following:
6x = 408
x = 68
y = 120-48 = 52

Parson City Middle School has 1,340 students. About 38% of the students are in the seventh grade. About how many seventh-graders attend Parson City Middle School?
Answer: About 509 seventh-graders attend Parson City Middle School.
Step-by-step explanation:
Total students in the school = 1,340
About 38% of the students are in the seventh grade.
Number of students in the seventh grade = 38% of (Total students in the school)
= 0.38 x (1340) [38%= 0.38]
= 509.2 ≈ 509
Hence, About 509 seventh-graders attend Parson City Middle School.
