Answer:
To graph the equation of a line, we plot at least two points whose coordinates satisfy the equation, and then connect the points with a line. We call these equations "linear" because the graph of these equations is a straight line.There are two important things that can help you graph an equation, slope and y-intercept.SlopeWe're familiar with the word "slope" as it relates to mountains. Skiers and snowboarders refer to "hitting the slopes." On the coordinate plane, the steepness, or slant, of a line is called the slope. Slope is the ratio of the change in the y-value over the change in the x-value. Carpenters and builders call this ratio the "rise over the run." Using any two points on a line, you can calculate its slope using this formula.Find the measurement of angle A & B
Answer:
Angle A = 65
Angle B = 78
Step-by-step explanation:
This is a triangle, and the total angles in a triangle is 180 degrees. What you can do is make all of the angles equal 180 and then solve for x.
180 = (2x +4) + (2x - 9) + x
180 = 2x +4 + 2x - 9 + x
180 = 4x -5 +x
180 = 5x - 5
185 = 5x
37 = x
Now, plug in x to solve for the angles.
Angle A = 2(37) - 9 = 65 Angle B = 2(37) + 4 = 78Angle C = x = 37what is the slope of the line -9x + 7y = 63
Answer: I think its x = 38

Answer:
9/7
Step-by-step explanation:
find the value of the variable and BC, if B is between A and C.
AB = 5x, BC = 3x-1, AC = 47
Answer:
17
Step-by-step explanation:
AC = AB + BC
Since we know what each variable equals, we can write out the equation as shown:
47 = 5x + 3x - 1
Combining like terms:
47 = 8x - 1
Add 1 on both sides:
48 = 8x
Divide 8 on both sides:
X = 6
Now that we know what X equals, we can solve BC.
BC = 3(6) - 1
BC = 18 - 1
BC = 17
Therefore BC = 17.
What is the equation in slope-intercept form of the line that passes through the points (-4,2) and (12,6)?
slope intercept is y=mx+b
Answer:
______the answer is Y=0.25X+3
What is the equation in point slope form of the line that passes through the point (-1, -4) and has a slope of -3
Do NOT answer just for points.
Answer:
y+4=-3(x+1)
Step-by-step explanation:
point slope form = y-y1=m(x-x1)
so plug in the numbers
y - -4 = -3 (x - - 1)
if there are two negatives it becomes a positive so your final answer is y + 4 = -3 (x +1)

Test 21,753 for divisibility by 2, 3, 5, 9, and 10.
3 and 9
2, 3, and 9
3
2 and 9
Answer:
21,753 is divisible by 3 and 9
Step-by-step explanation:
A number is divisible by 2 if last digit of a number is 0, 2, 4 ,6 ,8
A number is divisible by 3 if sum of digits is divisible by 3.
A number is divisible by 5 if last digit of a number is 0 or 5
A number is divisible by 9 if sum of digits is divisible by 9
A number is divisible by 10 if last digit is 0.
So, according to these rules option (a) 3 ,9 is correct
Therefore , 21,753 is divisible by 3 and 9.
Five times of a positive integer is less than twice its square by 3.
Find the integer.
Answer:
The positive integer is 3.
Step-by-step explanation:
Let 'x' be the integer
Given that five times of a positive integer is less than twice its square by 3.
so
5 times of x = [tex]5x[/tex]
3 less than twice of the square of x = [tex]2x^{2} - 3[/tex]
so the equation becomes
[tex]5x = 2x^{2} - 3[/tex]
[tex]2x^2-5x-3=0[/tex]
Factorise
[tex]\left(2x+1\right)\left(x-3\right)=0[/tex]
Using the zero factor principle
if ab=0, then a=0 or b=0 (or both a=0 and b=0)
[tex]2x+1=0\quad \mathrm{or}\quad \:x-3=0[/tex]
solving
[tex]2x+1=0[/tex]
Subtract 1 from both sides
[tex]2x+1-1=0-1[/tex]
Simplify
[tex]2x=-1[/tex]
Divide both sides by 2
[tex]\frac{2x}{2}=\frac{-1}{2}[/tex]
Simplify
[tex]x=-\frac{1}{2}[/tex]
Also solving
[tex]x-3=0[/tex]
Add 3 to both sides
[tex]x-3+3=0+3[/tex]
simplify
[tex]x=3[/tex]
Thus, we got integers:
x = 3 or x = -1/2
As x can not be a negative integer according to the question.Therefore, the positive integer is 3.

You are offered two jobs that you like. One job pays an hourly rate of $15.00 per hour for a 40-hour work week. Employees can take a two-week paid vacation. The employer says you will work about 5 hours of overtime per week at time-and-a-half pay. The other job pays $38,000 per year. You will be expected to work at least 55 hours per week, and you will have two weeks vacation and sick leave. Which job would you choose? Why?
Answer:
Second Job
Step-by-step explanation:
I would take the second job because you will make more. And it has sick time in addition to vacation.
First job:
$15x40=$600 then add in overtime which will be paid at $22.50 (time and half) so $22.50x5=$112.50. Add the two together $600+112.50=$712.50 weekly.
Second job:
$38,000/52=$730.77 weekly

Answer:
Simplify both of them
Step-by-step explanation:
After simplify we get both ratio 2:7 and 10000:35000 are equal.
What is Ratio?
A ratio indicates how many times one number contain in another number.
Given that;
Both ratio are;
2:7 and 10000:35000
Now, Solve the ratio for simplifying;
Ratios are 2:7 and 10000:35000
First ratio is 2 : 7.
Clearly, This is already in simplest form.
Second ratio is 10000:35000
It can be written as;
10000:35000 = 10000/35000
= 10/35
= 2/7
Thus, After simplify we get both ratio 2:7 and 10000:35000 are equal.

What is the area, in square feet, of the shaded part of the rectangle below?
6-2x=y 14+3x=y plzzz helllllllllllllllp
Answer:
(- [tex]\frac{8}{5}[/tex], [tex]\frac{46}{5}[/tex] )
Step-by-step explanation:
Given the2 equations
6 - 2x = y → (1)
14 + 3x = y → (2)
Substitute y = 14 + 3x into (1)
6 - 2x = 14 + 3x ( subtract 3x from both sides )
6 - 5x = 14 ( subtract 6 from both sides )
- 5x = 8 ( divide both sides by - 5 )
x = - [tex]\frac{8}{5}[/tex]
Substitute x = - [tex]\frac{8}{5}[/tex] into either of the 2 equations for the corresponding value of y
Substituting into (1)
y = 6 - 2(- [tex]\frac{8}{5}[/tex] ) = [tex]\frac{30}{5}[/tex] + [tex]\frac{16}{5}[/tex] = [tex]\frac{46}{5}[/tex]
solution is ( - [tex]\frac{8}{5}[/tex], [tex]\frac{46}{5}[/tex] )
16. Find the value of y.
y + (2x -12) = 180 (since they are supplementary angles)
(2x-12) = 96 ( since they are alternate exterior angle)
2x = 96 + 12
2x = 108
x = 108/2
x = 54.
y+( 2x-12)=180
y+(2× 54 -12) = 180
y + (108-12) = 180
y + 96 = 180
y= 180-96
y = 84.

Answer:
The equation of the line passing through the points (4, 6) and (0, 6) will be:
y = 6The graph of the equation y = 6 is also attached.
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptGiven the points
(4, 6)(0, 6)Finding the slope between (4, 6)and (0, 6).
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [6 - 6] / [0 - 4]
= 0 / -4
= 0
Thus, the slope of the line = m = 0
The slope m = 0 means the line is horizontal. Because the slope of the horizontal line is 0.
As the y-values are not changing with respect to the x-values.
Therefore,
The equation of the line passing through the points (4, 6) and (0, 6) will be:
y = 6The graph of the equation y = 6 is also attached.

Each hexagon tile has an area of LaTeX: 18\sqrt{3} 18 3 in.2 . Solve for x. Then find the exact length of each side of the hexagon. (Hint: Six equilateral triangles make one hexagon.)
Answer:
The length of the side of the hexagon is [tex]2\sqrt{3}[/tex] inches.
Step-by-step explanation:
According to this question, we have a regular hexagon with a surface area of [tex]18\sqrt{3}\,in^{2}[/tex]. From Geometry, we know that all regular hexagons can be formed by six regular triangles, since the angle of one complete revolution (360º) divided by the number of triangles is equal to the internal angle of each triangle (60º). Then, the area of each triangle is found after dividing the complete area by the number of regular triangles:
[tex]A_{\triangle} = \frac{18\sqrt{3}\,in^{2}}{6}[/tex]
[tex]A_{\triangle} = 3\sqrt{3}\,in^{2}[/tex]
The area of the triangle as a function of the length of the side of the hexagon ([tex]l[/tex]), measured in inches, is determined by this equation:
[tex]A_{\triangle} = \frac{\sqrt{3}}{4} \cdot l^{2}[/tex] (1)
If we know that [tex]A_{\triangle} = 3\sqrt{3}\,in^{2}[/tex], then the length of the side of the hexagon is:
[tex]\frac{4}{\sqrt{3}}\cdot A_{\triangle} = l^{2}[/tex]
[tex]l^{2} = \frac{4\cdot \sqrt{3}}{3} \cdot A_{\triangle}[/tex]
[tex]l = 2\sqrt{\frac{\sqrt{3}}{3}\cdot A_{\triangle} }[/tex]
[tex]l = 2\sqrt{3}\,in[/tex]
The length of the side of the hexagon is [tex]2\sqrt{3}[/tex] inches.
