Answer:
.........Purple color point in graph
............Red color Line
.......Blue color line
Step-by-step explanation:
Given:
To Solve:
Graphically
Solution:
we know x = a is a Line Parallel to Y-axis and x-coordinate will be always a throughout the line.
Therefore,
is a line parallel to Y-axis and x-coordinate will be always 3 throughout the line.
Similarly,
we know y = b is a Line Parallel to X-axis and y-coordinate will be always b throughout the line.
Therefore,
is a line parallel to X-axis and y-coordinate will be always -1/2 throughout the line.
Now both the line will intersect on a Point say A(3, -1/2) as shown in the Graph below
.........Purple color point in graph
............Red color Line
.......Blue color line
Step-by-step explanation:
Percentage for Rollerblading
= Total - Percentage for Swimming - Percentage for Biking
= 100% - 43% - 15%
= 42%.
Answer: x=3.6; y=-2.5
Step-by-step explanation:
To solve this pair of equations, we can use elimination method.
5x+4y=8
10x-4y=46
Add both equations together to cancel out 4y.
15x=54 [divide both sides by 15]
x=3.6
Now that we know x, we can plug it back into any equation to find y.
5(3.6)+4y=8 [multiply]
18+4y=8 [subtract both sides by 18]
4y=-10 [divide both sides by 4]
y=-2.5
Now, we have x=3.6 and y=-2.5.
Answer:
Pamela worked 9 hours if she prepared 72 kilograms of dough.
Step-by-step explanation:
First we divide 72 by 16.
72 ÷ 16 = 4.5
Next we multiply 4.5 by 2.
4.5 * 2 = 9
So, the answer is 9 hours.
Hope this helps! :)
Answer:
20°
Step-by-step explanation:
One way of doing this is to find the constant of proportionality, k:
8k + 6k + 4k = 90° Then 18k = 90°, and k turns out to be 90/18, or 5.
Then the angles are 8(5), 6(5) and 4(5). The smallest of these angles is thus 20°
