Learning Task 1: Graph each pair of linear equations in one coordinate plane.
1. y = 2x + 2 and 2y = 4x + 4
2. Y= x-5 and y = -x + 3
3. Y = 2x-3 and y = 2x + 4
Answers
Answer:
We kindly invite you to see the explanation and images attached below.
Step-by-step explanation:
From Geometry we know that every line can be formed by knowing two two distinct points in a plane. Our stategy consist in using two distinct points for each linear equation in order to create our plot.
1) [tex]y = 2\cdot x + 2[/tex], [tex]A(x,y) = (0, 2)[/tex] and [tex]B(x,y) = (1,4)[/tex].
The line [tex]2\cdot y = 4\cdot x + 4[/tex] is a multiple of [tex]y = 2\cdot x + 2[/tex]. We present the graph below.
2) [tex]y = x-5[/tex], [tex]A(x,y) = (0,-5)[/tex] and [tex]B(x,y) =(1,-4)[/tex].
[tex]y = -x+3[/tex], [tex]C(x,y) = (0, 3)[/tex] and [tex]D(x,y) = (1,2)[/tex].
Finally, we proceed to plot each line and present the results below.
3) [tex]y = 2\cdot x-3[/tex], [tex]A(x,y) = (0,-3)[/tex] and [tex]B(x,y) = (1, -1)[/tex].
[tex]y = 2\cdot x + 4[/tex], [tex]C(x,y) = (0,4)[/tex] and [tex]D(x,y) = (1,6)[/tex].
Finally, we proceed to plot each line and present the results below.

Answer:
8. 9.1
9. 12.2
Step-by-step explanation:
8. let x represent the missing side:
Using pythagoras theorem;
13.3² = x² + 9.7²
x² = 13.3² - 9.7²
x² = 82.8 taking the square root of both sides;
x = 9.1
9. let y represent the missing side:
Using pythagoras theorem;
y² = 10² + 7²
y² = 149 taking the square root of both sides;
y = 12.2

A wouldn’t work, because 11 + 21 = 32, which is smaller than 33.
B wouldn’t work either, because 14 + 27 = 41, which is smaller than 43
C would work, because 11 + 13 = 24, which is larger than 23
D wouldn’t work, because 5 + 8 = 13, which is smaller than 15.
C is the only one that works, so the answer is C.

What is an sequence ?"Sequence and series is one of the basic topics in Arithmetic. An itemized collection of elements in which repetitions of any sort are allowed is known as a sequence, whereas series is the sum of all elements. An arithmetic progression is one of the common examples of sequence and series.
In short, a sequence is a list of items/objects which have been arranged in a sequential way.
A series can be highly generalized as the sum of all the terms in a sequence. However, there has to be a definite relationship between all the terms of the sequence."
The given sequence is 20, 40, 80, 160, 320
So it is clear that the each term of the sequence is being multiplied by 2. Hence, C is the correct option.
