Line CD passes through points (0, 2) and (4, 6). Which equation represents line CD?
y = 2x – 2
y = 2x + 2
y = x + 2
y = x – 2
Answers
Answer:
C
Step-by-step explanation:
We know that line CD passes through the two points (0, 2) and (4, 6).
First and foremost, let’s find the slope of the line. We can use the slope formula:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Where (x₁, y₁) and (x₂, y₂) are our two points.
So, let’s let (0, 2) be (x₁, y₁) and (4, 6) be (x₂, y₂). Substitute appropriately:
[tex]\displaystyle m=\frac{6-2}{4-0}[/tex]
Evaluate:
[tex]\displaystyle m=\frac{4}{4}=1[/tex]
Hence, our slope is 1.
Now, we can use the slope-intercept form:
[tex]\displaystyle y=mx+b[/tex]
Where m is our slope and b is our y-intercept.
Notice from our given points that we are given (0, 2).
So, our y-intercept is 2.
Therefore, we will substitute 1 for m and 2 for b. This yields:
[tex]\displaystyle y=(1)x+(2)[/tex]
Simplify:
[tex]\displaystyle y=x+2[/tex]
Hence, our answer is C.

Answer:
13×11=143cm[tex]{2}[/tex]Step-by-step explanation:
you do base times height
Answer:
110.5 cm²
Step-by-step explanation:
The figure is composed of a rectangle with a triangle on top.
Area of rectangle = 13 × 6 = 78 cm²
Area of triangle = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
Here b = 13 and h = 11 - 6 = 5 cm , then
A = [tex]\frac{1}{2}[/tex] × 13 × 5 = 32.5 cm°
Thus
total area = 78 + 32.5 = 110.5 cm²
When writing the coordinates does it matter if we put x or y first?
Answers
Answer:
hii
Step-by-step explanation:
yes it does matter the The x-coordinate always comes first, followed by the y-coordinate.
Answer:To locate (2,5), move 2 units to the right on the x-axis and 5 units up on the y-axis. The order in which you write x- and y-coordinates in an ordered pair is very important. The x-coordinate always comes first, followed by the y-coordinate.

Johnny says that 600 cm is not enough moulding for the baseboards that measure 5642 mm. Is he right in his statement? Explain
Answers
Answer:
Johnny is wrong.
Step-by-step explanation:
To compare two quantities, they must both be written in the same units. In this case, both must be in centimeters or millimeters. So, we must convert 600cm to millimeters or vice versa.
If we choose to use milimeters, we have
600cm=600cm [tex]\frac{10mm}{1cm}[/tex]
600cm = (600)(10) mm
600cm = 6000 mm
Now, we must compare 6000 mm with 5642 mm. We can see that 6000mm is greater than 5642 mm. hence, it is enough moulding for the baseboards.
In fact, 6000-5642 mm =358 mm would remain.

When angles are complementary, the sum of their measures is 90 degrees. Two complementary angles have the measures of 2x - 10 degrees and 3x - 10 degrees. Find the measures of each angle
Answers
Answer:
2x - 10 = 34 degrees
3x - 10 = 56 degrees
Step-by-step explanation:
Since they're complementary, they'd equal 90-degrees.
Solve for x:
2x - 10 + 3x - 10 = 90
5x -20 = 90
5x = 110
x = 22
2(22)-10 = 34

KL = 7, JL = 24, and JK = 25. Find tan J.
Answers
Answer:
Tan J = 0.2917
Step-by-step explanation:
Here, we want to find the value of tan J
Firstly, we need to understand that the numbers 24, 25 and 7 are a Pythagorean triple and as such the three measures represent the values of length of the sides of a right angled triangle
The tangent of an angle= measure of the opposite/measure of the adjacent
In the question, the opposite to point J measures 7 while the adjacent measures 24
So ;
tan J = 7/24
= 0.2917

Rameez borrowed Rs. 20,000 from a bank at the rate 5% p.a compounded annually. What amount will he pay at the end of three years to clear the loan?
Answers
Answer:
23000
Step-by-step explanation:
If you multiply 20,000 * 0.05 (the percentage of the rate) you get 1000
This means that for 3 years he will pay an interest of 3000, plus the original loan 20000 which means he will pay 23000 :D

find an equation of the line that has a y-intercept of -1 that is parallel to the graph of the line x - 3y = 6

y = [tex]\frac{1}{3}[/tex] x - 1

x - 3y = 6 ⇔ y = [tex]\frac{1}{3}[/tex] x - 2
y = [tex]\frac{1}{3}[/tex] x - 1
3y = x - 6
y = 1/3x - 2
