Evaluate 2-10+8-\left(-2\right)2−10+8−(−2)2, minus, 10, plus, 8, minus, left parenthesis, minus, 2, right parenthesis.
Answers
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.

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).

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.
Answers
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°.

Answers
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 ^-^

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?
Answers
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

Could someone please show me how to factor this using the x method
Answers
Answer:
(x + 2) (8x + 3)
Step-by-step explanation:
[tex]8x^{2}[/tex] + [tex]19x + 6[/tex]

L = 3/a = 3/8
R = 16/a = 16/8 = 2
\ac/
L V R
/ \
/ b \
where letters have their usual meaning. Comparing 8x² + 19x + 6 to ax² + bx + c,
ac = 8*6 = 48
b = 19
Factors of ac or 48 :-
1 * 48
2 * 24
3 * 16
As the sum of 3 and 16 is 19(or b), our required pair is 3 and 16.
On the left side:
L = 3/a = 3/8
On the right side:
R = 16/a = 16/8 = 2
Therefore, factorized form is (x + 3/8)(x + 2) which can be written as (8x + 3)(x + 2).
How this method works:
Make a X with ac and b on the top and bottom of the X, where ac and b are taken from ax² + bx + c.
On the left side we have d/a and e/a. Basically d and e are those values that we get after solving the whole question.
Step1: find the pair(s) for which sum of factors of ac = b. Here it is 3 and 16.
Step2: put these values in place of d and e.
Step3: solve left anf right of X,
Left = d/a = 3/8
Right = e/a = 16/8 = 2
Step4: whatever you get, put that in (x+?)(x+?) in place of ?.

What is the equation of a line parallel to the y axis and passing through the point (2,1)?
Answers
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.

Alyssa is trying to pick out an outfit for the first day of school. She can choose
from 4 pairs of pants, 8 t-shirts, 8 sweaters or hoodies, and 5 pairs of shoes.
How many different outfits does Alyssa have to choose from?
Answers
4x8x8x5 = 1280

How to determine the number of different outfits?From the question, we have the following parameters that can be used in our computation:
8 pairs of pants, 6 t-shirts, 6 sweaters or hoodies, and 2 pairs of shoes
The number of different outfits is equal to the products of the count of each apparel.
This is represented as;
Different outfits = Pants * T-shirts * Sweaters or hoodies * Pairs of shoes
Substitute the known values in the above equation;
Different outfits = 4 x 8 x 8 x 5
Evaluate;
Different outfits = 1280
Hence, there are 1280 different outfits
