What is the equation of a line parallel to the y axis and passing through the point (2,1)?
Answer:
x = 2
Step-by-step explanation:
lines parallel to the y-axis are always vertical and begin with 'x ='
Answer:
x=2
Step-by-step explanation:
Hi there!
A line parallel to the y-axis would make it a vertical line. Vertical lines have the equation x=d, where d is the x-intercept (the value of x when y=0).
We also need to know that every point a vertical line passes through has the same x-coordinate. Therefore, because this line passes through the point (2,1), we know that the x-intercept is (2,0).
Therefore, the equation of the line would be x=2.
I hope this helps!

Sarah hiked a path that took her from 34 feet below sea level to 52 feet above sea level . What was the change in her elevation?
Answer:
86 ft
Step-by-step explanation:
First method: Logical thinking
Think of the position 34 ft below sea level as -34.
The position above sea level is 52.
You need to find the distance between -34 and 52.
You go from 34 ft below sea level, -34 to 0. That is 34 ft.
Then you go from sea level, 0 ft, to 52 ft above sea level. That is 52 ft.
The total is 34 ft + 52 ft = 86 ft
Answer: 86 ft
Second method: Calculate a distance in math
The distance between two points on a number line is the absolute value of the difference of their coordinates. The coordinates are -34 and 52. Subtract the numbers in either order, and take the absolute value of the difference.
|-34 - 52| = |-86| = 86
If you did it in the other order, you'd get the same answer.
|52 - (-34)| = |52 + 34| = |86| = 86
Answer: 86 ft

Recall that two angles are complementary if the sum of their measures is 90. Find the measures of two complementary angles if one angle is 15 degree more than two times the other angle.
Answer: 25° and 65°
Step-by-step explanation:
Let the smaller angle of the complementary angle be represented by x.
Since the other angle is 15 degree more than two times the other angle, this will be:
= (2 × x) + 15°
= 2x + 15°.
Then we add both angles together and equate them to 90° and this will be:
x + 2x + 15° = 90°
3x + 15° = 90°
3x = 90° - 15°
3x = 75°
x = 75°/3
x = 25°
Then the other angle will be:
= 2x + 15°
= (2 × 25°) + 15°
= 50° + 15°
= 65°
Therefore, the angles are 25° and 65°.

Graph: y = |x-4| + 2
Click or tap the graph to plot a point
The graph of the absolute value function can be seen at the end of the answer.
How to graph the absolute value function?For an absolute value function:
y = |x - a| + b
We need to start by graphing the vertex, which is the point (a, b).
Then, depending on the slope, we graph the arms.
In our case:
y = |x - 4| + 2
The slope is 1, so both the arms will open upwards with a 45° angle, and we can see that the vertex is (4, 2).

Answer:
4 white horses.
Step-by-step explanation:
First, you need to find the total of the first set of horses (basically how many total were in the table).
~ 3+2+9+1 = 15
Next we need to find how many horses were white horses out of these 15 horses. In short the proportion would be White Horses/Total Horses.
~ [tex]\frac{3}{15}[/tex] (or [tex]\frac{1}{5}[/tex], simplified)
Now, all we need to do is create the proportion with 20 as the denominator (in this case, 20 will be the total horses, and we just need to find X, or how many horses are expected to be white out of all of those horses). The proportion will look somewhat like this:
~ [tex]\frac{1}{5}[/tex] = [tex]\frac{x}{20}[/tex]
The final step is to multiply across (1x20) then divide that number by the 5 to find X.
~ 20÷5 = 4
Anyways, that means it would be expected to have 4 white horses out of 20 total. Hope this helped ^-^
Evaluate 2-10+8-\left(-2\right)2−10+8−(−2)2, minus, 10, plus, 8, minus, left parenthesis, minus, 2, right parenthesis.
Answer:
Here we want to solve the equation:
"2, minus, 10, plus, 8, minus, left parenthesis, minus, 2, right parenthesis."
This can be written as:
2 - 10 + 8 - (-2)
Remember that we can solve this in any order we want, so let's go from left to right:
So we can solve first:
( 2 - 10) + 8 - (-2)
We know that:
2 - 10 = -8
Then we can replace that in the expression to get:
( 2 - 10) + 8 - (-2) = -8 + 8 -(-2)
Now we can solve:
(-8 + 8) - (-2)
We know that:
-8 + 8 = 0
Replacing that in the equation we get:
(-8 + 8) - (-2) = 0 - (-2) = -(-2)
And now we can remember the rule of the signs:
(+)*(+) = (+)
(-)*(-) = (+)
(-)*(+) = (-)
(+)*(-) = (-)
Then:
-(-2) = (-1)*(-2) = +(1)*(2) = 2
The solution of the expression is 2.
Answer:
The answer is 2

Find the value of x. -1x + 72 = -3x + 84
Answer:
x=6
Step-by-step explanation:
First, add x to each side.
72=-2x+84
Subtract 84 from each side
-12=-2x
Dive each side by -2
6=x
Answer:
x=6
Step-by-step explanation:
-1x+72=-3x+84
+3x on both sides
2x+72=84
subtract 72 on both sides
2x=12
divide by 2 on both sides
x=6
