Answer:
y=0.5x+6
Step-by-step explanation:
6 is the y-intercept because you go up 1 over 2.
Answer: The equation of line is [tex]2y - x - 12 = 0[/tex]
Step-by-step explanation:
The formula for finding the equation of a line when slope and a point is gives is :
[tex]y-y_{1}=m(x-x_{1})[/tex]
[tex]x_{1}=-2[/tex]
[tex]y_{1}=5[/tex]
[tex]m = 1/2[/tex]

Answer:
33
Step-by-step explanation:
You find the measure of B, which is 180 - (93 + 58) = 29 degrees
You use the law of sines which is 16/sin(29) = (BC)/sin(93)
You multiply both sides by sin(93) and get:
sin(93)*16/sin(29) = BC
You plug this into a calculator and get:

Step-by-step explanation:
There are 3 less than twice as many cats than dogs in the local animal shelter. If there are 210 cats and
dogs combined, how many dogs are in the animal shelter?
There are 71 dogs in the local animal shelter.
To determine the number of dogs and cats in the shelter, let's denote the number of dogs by D and the number of cats by C. According to the problem statement, there are twice as many cats as dogs, minus three. Mathematically, this is represented as C = 2D - 3. We also know that the combined total of cats and dogs is 210, which can be expressed as C + D = 210. To find the number of dogs, we can solve these two equations simultaneously.
From the first equation, we solve for C in terms of D: C = 2D - 3.
Substitute C into the second equation: (2D - 3) + D = 210.
Combine like terms: 3D - 3 = 210.
Add 3 to both sides of the equation: 3D = 213.
Divide both sides by 3 to solve for D: D = 71.
Therefore, there are 71 dogs in the local animal shelter.

Angle 1 is 100 degrees. What is the measure of angle 3?
Answer:
Angle 3 is also 100
Step-by-step explanation:
They are vertical angles and vertical angles are always congruent.
The angle 3 is in the given figure is ∠3 = 100°.
What are parallel lines?
The parallel lines are a group of straight lines that never intersect with one another. The distance between two parallel is always the same.
The measure of angle 1 is given as ∠1 = 100°.
When two lines intersect each other, the pair of vertically opposite angles are equal.
Since, angle 1 and angle 3 are vertically opposite, they are equal.
Thus, ∠3 = 100°.
Hence, the measure of angle 3 is 100°.

The slope of M would be 3/4.
Step-by-step explanation:
m = y^2 - y^1/x^2 - x^1 = 7 - 4/ 8 - 4 = 3/4. m = 3/4.
y = mx + b
y = 3/4 x + b
4 = (3/4)(4) + b
b = 4 - 3 = 1
The equation of line AB is y = 3/4 x + 1.

Ethan will subtract a 3-digit number
from 920. He says the difference could be a 1-digit
number, a 2-digit number, or a 3-digit numbens
Write three subtraction equations that show each
difference. Be sure you start with 920 and subtract a
3-digit number each time
Subtracting smaller 3-digit numbers from 920 results in 3-digit answers, subtracting larger 3-digit numbers gives 2-digit answers, and subtracting even larger 3-digit numbers results in 1-digit answers. Examples include: 920 - 120 = 800, 920 - 825 = 95, and 920 - 915 = 5.
Explanation:This question involves simple subtraction operations. Here are three subtraction equations that meet the conditions:
For a 3-digit result: 920 - 120 = 800. Here, subtracting a 3-digit number (120) from our original number (920) results in a 3-digit number (800). For a 2-digit result: 920 - 825 = 95. In this case, subtracting a bigger 3-digit number (825) leaves us with a 2-digit number (95). For a 1-digit result: 920 - 915 = 5. Subtraction of an even larger 3-digit number (915) results in a 1-digit number (5).
As we increase the 3-digit number that we subtract from 920, the result decreases in the number of digits,

To subtract 3 digit numbers from 920 and end up with a 1-digit, 2-digit or 3-digit number, the following equations are provided: 920 - 911 = 9, 920 - 815 = 105 and 920 - 100 = 820.
Explanation:To find three subtraction equations that show the difference when subtracting a 3-digit number from 920, we need to consider all possible scenarios for the difference.
The smallest possible difference would be a 1-digit number.
To get a 1-digit number, 2-digit number, or a 3-digit number as the result while subtracting a 3-digit number from 920, here are three equations:
• The smallest possible difference would be a 1-digit number. 920 - 911 = 9
• The next possible difference would be a 2-digit number. 920 - 815 = 105
• The largest possible difference would be a 3-digit number. 920 - 100 = 820
In each equation, we started with 920 and subtracted a 3-digit number. Given that the numbers we subtract are less than 920, it becomes possible to get a 1-digit, 2-digit, or 3-digit result.

3.5(2.25 + x) = 14
Answer:
1.75
Step-by-step explanation:
Use the distributive property first.
(3.5 x 2.25) (3.5 x X) = 14
7.875 + 3.5x = 14 Now subtract 7.875 from both sides
3.5x = 6.125 Now divide 3.5 by both sides
x = 1.75
The equation 3.5(2.25 + x) = 14 is solved by first distributing 3.5 through the parentheses, then isolating x on one side, yielding a result of x = 1.75.
Explanation:In this mathematical equation, the first step is to distribute 3.5 to (2.25 + x). The result is 7.875 + 3.5x = 14. We then subtract 7.875 from both sides to isolate the term with x which gives 3.5x = 6.125. Finally, to solve for x, we divide both sides by 3.5. This gives us x = 1.75.

Step-by-step explanation:
[tex]100*19=1900\\10*11=110\\1900+110=2010[/tex]
Answer:
11
Step-by-step explanation:
Let x be how many $10 bills there are.
Let y be how many $100 bills there are
x + y = 30
x = 30 - y
10x + 100y = 2010
10(30 - y) + 100y = 2010
300 - 10y + 100y = 2010
-10y + 100y = 2010 - 300
90y = 1710
y = 1710 / 90
y = 19
x = 30 - 19
